Authors: Barrett Paul E. , Dieck Christopher , Beasley Anthony J. , Singh Kulinder P. , Mason Paul A.
Published: November 2017

The Jansky Very Large Array was used to observe 121 magnetic cataclysmic variables (MCVs). We report radio detections of 18 stars. Thirteen are new radio sources, increasing the number of MCVs that are radio sources by more than twofold, from 8 to 21. Most detections are at 8.7 GHz (X-band) with a lesser number at 5.4 and 21.1 GHz (C- and K-bands). With the exception of AE Aqr, whose flux density is typically >5 mJy, the flux densities are in the range of 24–780 μJy. Thirteen of the detections show highly circularly polarized emission, which is characteristic of electron-cyclotron maser emission. The data suggest that MCVs could possibly be divided into two classes of radio emitters: those dominated by weakly polarized gyrosynchrotron emission and those by highly polarized electron-cyclotron maser emission.

Published: November 2017

After the early observations of the disrupted asteroid P/2016 G1 with the 10.4 m Gran Telescopio Canarias (GTC) and modeling of the dust ejecta, we have performed a follow-up observational campaign of this object using the Hubble Space Telescope (HST) during two epochs (2016 June 28 and July 11). The analysis of these HST images with the same model inputs obtained from the GTC images revealed a good consistency with the predicted evolution from the GTC images, so that the model is applicable to the entire observational period from 2016 late April to early July. This result confirms that the resulting dust ejecta was caused by a relatively short-duration event with onset about 350 days before perihelion and spanning about 30 days (HWHM). For a size distribution of particles with a geometric albedo of 0.15, having radii limits of 1 μm and 1 cm, and following a power-law with index −3.0, the total dust mass ejected is ∼2 × 107 kg. As was the case with the GTC observations, no condensations in the images that could be attributed to a nucleus or fragments released after the disruption event were found. However, the higher limiting magnitude reachable with the HST images in comparison to those from GTC allowed us to impose a more stringent upper limit to the observed fragments of ∼30 m.

HC3N is a ubiquitous molecule in interstellar environments, from external galaxies to Galactic interstellar clouds, star-forming regions, and planetary atmospheres. Observations of its rotational and vibrational transitions provide important information on the physical and chemical structures of the above environments. We present the most complete global analysis of the spectroscopic data of HC3N. We recorded the high-resolution infrared spectrum from 450 to 1350 cm−1, a region dominated by the intense

and

fundamental bands, located at 660 and 500 cm−1, respectively, and their associated hot bands. Pure rotational transitions in the ground and vibrationally excited states were recorded in the millimeter and submillimeter regions in order to extend the frequency range so far considered in previous investigations. All of the transitions from the literature and from this work involving energy levels lower than 1000 cm−1 were fitted together to an effective Hamiltonian. Because of the presence of various anharmonic resonances, the Hamiltonian includes a number of interaction constants, in addition to the conventional rotational and vibrational l-type resonance terms. The data set contains about 3400 ro-vibrational lines of 13 bands and some 1500 pure rotational lines belonging to 12 vibrational states. More than 120 spectroscopic constants were determined directly from the fit, without any assumption deduced from theoretical calculations or comparisons with similar molecules. An extensive list of highly accurate rest frequencies was produced to assist astronomical searches and data interpretation. These improved data enabled a refined analysis of the ALMA observations toward Sgr B2(N2).
Data-driven Modeling of the Solar Corona by a New Three-dimensional Path-conservative Osher–Solomon MHD Model

Published: November 2017

A second-order path-conservative scheme with a Godunov-type finite-volume method has been implemented to advance the equations of single-fluid solar wind plasma magnetohydrodynamics (MHD) in time. This code operates on the six-component composite grid system in three-dimensional spherical coordinates with hexahedral cells of quadrilateral frustum type. The generalized Osher–Solomon Riemann solver is employed based on a numerical integration of the path-dependent dissipation matrix. For simplicity, the straight line segment path is used, and the path integral is evaluated in a fully numerical way by a high-order numerical Gauss–Legendre quadrature. Besides its very close similarity to Godunov type, the resulting scheme retains the attractive features of the original solver: it is nonlinear, free of entropy-fix, differentiable, and complete, in that each characteristic field results in a different numerical viscosity, due to the full use of the MHD eigenstructure. By using a minmod limiter for spatial oscillation control, the path-conservative scheme is realized for the generalized Lagrange multiplier and the extended generalized Lagrange multiplier formulation of solar wind MHD systems. This new model that is second order in space and time is written in the FORTRAN language with Message Passing Interface parallelization and validated in modeling the time-dependent large-scale structure of the solar corona, driven continuously by Global Oscillation Network Group data. To demonstrate the suitability of our code for the simulation of solar wind, we present selected results from 2009 October 9 to 2009 December 29 show its capability of producing a structured solar corona in agreement with solar coronal observations.

Dans un récent travail de thèse présenté en décembre dernier (2010), Yann Calbérac porte son regard sur la manière dont les géographes ont pris l’habitude d’interroger la place qu’occupe le terrain au sein de leurs démarches, ou plutôt celle qu’ils ont longtemps prise de ne pas la questionner. Il souligne notamment le paradoxe entre l’importance ancienne que revêt celui-ci dans la démarche et l’identité du géographe, ainsi que le manque de réflexivité à son égard, l’impensé qu’il a longtemps pu constituer. Ce travail de thèse semble aujourd’hui participer à une certaine ré-interrogation de la pratique du terrain par les géographes.

Published: November 2017

In recent days nanotechnology has become one of the most excellent escalating technologies in the field of engineering and scientific areas. During the last decade there are numerous experimental analysis was carried out by many scholars on nanoparticles. This research work was carried out through different samples with varied composition of the nano-materials and the results were found on the optimisation of machining parameters of copper-multiwalled carbon nanotubes-graphene hybrids. The machining parameters of the hybrid composites were optimized using Taguchi method after the hybrid composite was made by stir casting process and analysis of variance (ANOVA) was used to analyse data and find the most influencing factor. The Taguchi’s signal to noise ratio was used is ‘smaller is better’. Confirmatory examinations were also performed for the purpose of validation after obtaining the optimized results. The hybrid nanocomposite specimens thus prepared were characterized by scanning electron microscope. From the results it was found that the addition of carbon nanotubes and graphene into copper leads to lower surface roughness values compared to pure copper.

Published: November 2017

In the present study, the effects of different parameters of needleless electrospinning systems on polyacrylonitrile (PAN) nanofibers morphology and diameter were studied. The electric field profile at the surface of the spinneret and electrospinning zone was evaluated by Finite Element Method. The PAN nanofibers were used as the precursor to fabricate carbon nanofibers. Scanning electron microscope (SEM), X-ray diffraction and Raman spectroscopy were used for electrospun nanofibers analysis. The results of electric field analysis indicated, in the spinning direction, the electric field was concentrated at the surface of the spinneret and decayed rapidly toward the surface of the collector. Increasing polymer solution concentration from 7.00 to 11.00 wt.% resulted increasing nanofibers diameter form 77.76 ± 19.44 to 202.42 ± 36.85. The results of X-ray diffraction and Raman spectroscopy show that heat treatments could convert needleless electrospun PAN nanofibers to carbon nanofibers.
Prenatal Diagnosis of Cross-fused Renal Ectopia: Still a Dilemma
Authors: Singhania Pooja
Published: November 2017

Cross-fused renal ectopia (CRE) is a rare congenital anomaly where during development of the fetus, one kidney migrates to the opposite side and fuses with the kidney of that side. Crossfused ectopic kidney with contralateral pelvic kidney is a rare finding. Proper knowledge of morphological variations of kidneys is essential to avoid postnatal renal dysfunction and morbidity.

Comparative Study of Potential Diagnostic Biomarkers in Myocardial Infarction with Survival and Myocardial Infarction without Survival
Authors: Patil Sangita M , Bankar Mangesh , Padalkar Ramchandra , Phatak Abhijit
Published: November 2017

Introduction

Because of the varied presentation and associated high mortality, the identification of patients with acute myocardial infarction (MI) is very critical for patient management and has a bearing on the prognosis. The goal of present study was to correlate the diagnostic value of cardiac biomarkers in MI with survival and MI without survival.

Materials and methods

Diagnostic case—control study was conducted on 110 MI patients presenting to the Emergency Department within 12 hours of acute chest pain, and 120 healthy age- and sex-matched volunteers formed the control group. Serum ischemia-modified albumin (IMA), troponin I (TnI), creatine kinase-MB (CK-MB), lactate dehydrogenase (LDH), and aspartate transaminase (AST) were measured. Statistical software SYSTAT version 12 was used to analyze the data. The results were expressed in mean ± standard deviation. Comparisons of study groups and study groups with control groups were done by applying Z test. Correlation was tested by Student's t-test at 5% (p = 0.05) and 1% (p = 0.01) level of significance.

Results

Mean levels of serum IMA, TnI, CK-MB, LDH, and AST levels were significantly higher (p < 0.01) in patients with MI as compared with healthy controls. Serum levels of cardiac biomarkers were significantly elevated (p < 0.01) in MI patients without survival as compared with MI with survival.

Conclusion

The serum levels of biomarkers were increased in MI without survival as compared with MI with survival. These study data prove that these changes might be helpful to obtain a comprehensive view of the infarct size and severity of vascular stenotic lesions.

Study of Parathyroid Hormone as an Independent Risk Marker of Heart Failure
Authors: Iyyapu Krishna M , Yerram Sreekanth , Sai Baba Kompella SS
Published: November 2017

Introduction

Heart failure (HF) is a clinical syndrome characterized by cardiac pump failure with signs and symptoms arising from salt and water retention. Heart failure is associated with considerable mortality and morbidity. Identification of modifiable risk factors may reduce incidence of HF and its complications. The aim of our study is to assess parathyroid hormone (PTH) as a risk marker for HF and its association with severity of HF.

Materials and methods

In this cross-sectional study, 120 subjects with HF were recruited and they were compared with 60 age- and sex-matched controls. Along with the routine parameters, N-terminal pro B-type natriuretic peptide (NT-proBNP), intact PTH, and vitamin D were estimated. The study group was divided into quartiles depending on PTH value.

Results

The median PTH (81.5 pg/mL) and NT-proBNP (3753 pg/mL) in HF patients are found to be significantly higher (p < 0.0001) when compared with control subjects. The median vitamin D concentration (18 ng/mL) though low in cases is not statistically significant when compared with controls. Demographic, clinical, and laboratory characteristics are compared across the quartiles of PTH. Highest number of New York Heart Association (NYHA) class IV HF cases are found in highest quartiles of PTH. Logistic regression analysis demonstrated that high concentration of PTH [odds ratio of 1.1113; 95% confidence interval (CI) 1.07—1.14; p < 0.0001] and low levels of vitamin D (odds ratio of 1.053; 95% CI 1.0079—1.1009) are significantly associated with HF.

Conclusion

This study has demonstrated that higher concentration of PTH is associated with severe form of HF. Vitamin D deficiency is also seen in the study group.

Published: November 2017

Abstract. Forty three bulls (13 Holstein, 12 crosses Holstein x Belgium Blue, 9 Slovak Pied and 9 crosses Slovak Pinzgauer x Piemontese) were taken in this experiment. Thirteen were stressed by mixing overnight before slaughter. Muscle values were analysed for glycogen ante mortem (M. semitendinosus), glycogen and pH post mortem (1 h, 3 h, 48 h) from logissimus dorsi. The ante mortem and post mortem (1 h, 3 h) muscle glycogen concentration was depleted (P < 0.01) in all stressed bulls. Differences (P < 0.01) were found also in pH (48 h). Significant correlations (P < 0.01) between ante mortem and post mortem (1 h, 3 h) muscle glycogen respectivelly and ultimate pH supported the possibility to measure of stress and to predict carcass ultimate pH of bulls.
Relationship between transferrin and ceruloplasmin polymorphism and the frequency of diarrhoea in piglets
Authors: Zyczko K. , Zyczko G. M.
Published: November 2017

Abstract. The relationship between a phenotype of transferrin (Tf) and ceruloplasmin (Cp) and the frequency of diarrhoea occurrence was analysed in 317 piglets. It was observed that diarrhoea caused by haemolytic Escherichia coli strains including K88 ab and K88 ac occurred with greater frequency in piglets with phenotypes Tf AB and Cp AB than in piglets with phenotypes Tf BB and Cp BB. It is believed that Polymorphie type of Tf A and Cp A is related with piglets susceptibility to colibacteriosis which is caused by strains E. coli K88 ab and K88 ac.

Abstract. Title of the paper: Mother-infant-relationships in a beef suckler cow herd A beef suckler cattle herd (25 cows, 23 calves) was observed on pasture for mother-infant behaviour. This behaviour varied substantially in that 20 different suckling positions (with one, two or three calves suckling per cow) were observed during 299 sucklings. The frequent occuring cross suckling, the diversity of suckling positions as well as the behaviour of cows during suckling are discussed in the context of the current literature. In contrast to the literature, our results showed a higher incidence of cross suckling and a variety of suckling positions, indicating a disturbed bonding between the cow and its calf during birth. The preferred lying order of the herd showed parallel lying positions along the periphery of the pasture. In conclusion, the results should encourage farmers to design their pastures according to the animal needs as well as including regular herd observations into herd management schemes.

Abstract. A total of 1,33,507 eggs obtained from 7864 pullets of two selected White Leghorn strains over four generations representing 304 sires and 1669 dams were incubated. The unhatched eggs were broken-open for examination of embryonic development and classified as early-dead (0-11d), late-dead (12-22d) and pips. The sire component heritabilities (%) pooled over years in the two strains, respectively were 10.5±3.4 and 11.0±3.2 for total incubation mortality; 2.2 ± 2.2 and 5.1 ± 2.4 for early-dead; 6.8 ± 3.0 and 8.0 ± 3.0 for late-dead and 8.7 ± 3.1 and 4.8 ± 2.4 for pips. Total embryonic mortality as well as its three components had high genetic correlations amongst each other. However, the genetic correlations of pipping mortality with early and late mortality were weaker as compared with those of early and late mortality.

Abstract. Title of the paper: Studies on the influence of synchronization of parturition as with regard to features of the animal health of partus sows and piglets The tests were carried out in a piglet produetion plant with 1275 sow places which is mn on a 7-day-cycle based on the penodical farrowing system. The tests were splitted into 2 stages. In the first stage 263 controlled sows were farrowing spontaneously after a gestation period of 112.9 ± 1.03 days. 637 sows still awaiting birth did get preferably on the 114th day an injection initiating parturition of Cloprostenol in the dosages of 50ug (N = 219) lOOug (N = 206) resp. 175 ug (N = l 12). Parturition did start on an average after 20.3; 24.4 resp. 21.2 hours and the quota of farrowing sows up to 36 hours post injectionem did reach 95.4; 94.2 resp. 97.2% (not significant). The partus sows treated biotechnically did show agalacttca less often (less 8.8%) and did have a normal body inner temperature (+ 8.7%). With an increasing partus period exceeding 4 hours the rate of stillbirth went up by 4% to 9.9%. An equalization of litter was made. In the second stage 170 sows with spontaneous parturition did form the control group. 369 sows were given 50ug Cloprostenol on the 114th day of gestation and another 187 sows which did not farrow within 24 hours got another injection of 0.07 mg Carbetocin in 1 ml Depotocin. Amongst the sows treated with biotechnical initiation of parturition 8.2 % did show less discharge. In both stages the rearing success ofthe sows treated biotechnically did exceed that one of the animals by 0.51 resp. 0.41 weaned piglets each litter (p < 0,05).

Abstract. Title of the paper: The influence of the age of first calving on fertility and Performance in dairy cows The influence of the age of first calving (respectively heifer conception age) on later fertility was investigated according to the lactation reports of 8 German herds (n = 4125), one US-American (n = 300) herd as well as to the annual average data of 206 Israeli herds. All the correlation coefficients were set nearly zero. The optimal sphare for the age of first calving regarding some milk performance characteristics is from 24–26 months. This can be infeired from the variance analyses from the comparisons among the groups. The analysis of 1032 heifer births showed a rising tendency in the frequency of dystocias in higher age of first calving.
An Illustration of lactation curves stratified by lactation yields within herd
Authors: Swalve H. H. , Guo Z.
Published: November 2017

Abstract. Based on the lactation curves ofa total of 817 cows from three herds the Variation of the shape of lactation curves is illustrated stratified by herd, lactation number and total lactation produetion. The data was collected from on-farm Computers connected to recording of yields on a daily basis. The results from this ongoing project show that a differentiation of cows according to total yield per lactation or 305-day yield based on records from early lactations is difficult and thus highly questions the set-up of yield groups in the beginning ofthe lactation. The results also illustrate that it is still debatable what kind of criterion for the persistency of lactation produetion should be used. This question should be answered in relation to the desired length of lactation. Today, random regression models for the genetic evaluation of dairy animals seem to be a promising alternative to more traditional methods. Future research in this field should make use of data from daily recordings since by this the impaet ofthe data structure can be analysed by mimicking different recording scenarios.
Genetic and economic evaluation of genetic improvement schemes in pigs – I. Methodology with an application to a three-way crossbreeding scheme
Authors: Wuensch U. , Nitter G. , Schueler L.
Published: November 2017

Abstract. A method is presented for evaluating selection strategies for a three-way cross in pigs. Multitrait selection is considered. The criteria of evaluation are the annual genetic gains in the breeding objeetive and its component traits, and the profit which is the net present value of return from investment in the scheme. Selection in the sire line (Pietrain) contributes higher returns than selection in the dam lines. Meat percentage is the dominant trait in the sire line and has the highest impact on the breeding objective. The sire line is characterised by a negligible economic weight for the reproduction trait and has higher weights than dam lines for growth and carcass traits. The higher discounted economic values of these traits for Pietrain compared to those for dam lines deviate considerably from the equal weighting often applied in practical breeding programmes.

Abstract. Title ofthe paper: Boar fattening with different protein supply in the diet In the literature numerous studies are found that proof a superior fattening performance and carcass composition for boars compared to female and castrated pigs. The results in the feeding experiment presented here do not confirm this to the same extend. Even with a high protein and lysine supplementation growth performance of boars was lower than in females. Lean content was determined by FOM grading which might underestimate the boars. Lean to fat ratio (areas of M. long dorsi and back fat) however was significantly different between castrates and all boar groups due to the reduced fat deposition. Sensoric tests detected significant boar taint in the majority ofthe samples from male carcasses. Considering the tendency on the market for increasing carcass weights and the risk of boar taint in heavier pigs boar fattening can not be recommended in Germany.

Abstract. Title of the paper: Inbreeding depression for litter traits and the development of growth in the Göttinger Minipig A data set of 1191 litters from 282 sows and 6777 piglets weights from the Göttinger Minipig was analysed to estimate inbreeding depression for litter traits and the early growth rates up to an age of 12 month. The population ofthe Göttinger Minipig shows an average inbreeding of sows and piglets of about 10% with a Standard deviation of 1.7% with a nearly normal distribution of the inbreeding coefficients in contrast to most other studies about inbreeding depression. There is no inbreeding depression observed for number of piglets bom alive or bom dead within a litter, neither for inbreeding of sows nor for inbreeding of litters. For average and individual birth weights the inbreeding of sows show a significant influence while the inbreeding of the litter is not significant. With a 10 percent increase of the inbreeding of sows a reduction on individual birth weight of 70 gram is observed (70% of the phenotypic Standard deviation). For the weight of piglets in the first 6 month both the inbreeding of sows and the inbreeding of litters show a significant effect. A 10 percent increase of inbreeding of sows or litters both leads to a reduction on weight within the first 6 month of 250 gram (20 % ofthe phenotypic Standard deviation.

Abstract. Three informative F2 families (by use of European Wild boar (W), Pietrain (P) and Meishan (M)), each with more than 300 animals, were genotyped for evenly spaced marker loci and recorded for more than 100 quantitative traits. Linkage and QTL mapping data for 8 chromosomes are presented (74, 76 and 75 mapped loci in families WxP, MxP and WxM, resp). Linkage maps gave evidence of heterogeneity in recombination between sexes and families. The male to female recombination ratio were 1.19 (WxP), 1.35 (MxP) and 1.27 (WxM). Several QTLs were mapped for performance traits of growth, carcass and meat quality. These QTLs are located on different chromosomes and influenced by families. Larger effects were found on chromosome 6 and 7, and e.g. up to 60% of the phenotypic F2 variance for meat quality traits was associated with chromosome 6. Candidate genes are proposed for some of the QTL intervals. The subsequent QTL mapping use a combined strategy of genome-wide marker mapping with a positional candidate gene approach in order to identify genes which are significant for breeding.

Abstract. Title of the paper: Relationships between parameters of the glucose tolerance test by young sires and estimated their breeding values A high milk Performance connected to a sound health regarding metabolism and a sufficient fertility in dairy cows depends on a well balanced distribution of energy in body. The terms "type of tumover" and "type of deposition" embody two extremes of food energy preferably for milk production or for body composition. Insulin plays an outstanding role based on its central position in energetic metabolism. The function of insulin may be recorded by means of the intravenous glucose tolerance test (GTT). The reaction of insulin and glucose was investigated after infusion of 1 g Glucose/kg075 because of the probable genetic determination of the reactive ability. The coefficients of heritability range from h2 = 0.16 + 0.10 to h2 = 0.28 ± 0.16. Investigating 28 sires the correlation coefficients amount to r = 0.5 for parameters of gluccose tolerance test and estimated breeding values which is closer than those between pedigree breeding value and glucose tolerance test.This is expecting additional Information for young sires before the insert of the test.

Abstract. The present study deals with estimation of genetic parameter for purebred and crossbred Performance of live born piglets, in order to choose the optimal selection method. Data sets of two pure breeds, line L03 and L04, with 5,422 sows, a two line crossbred, L303, with 3,553 sows and a three line crossbred, L350, with 3,609 sows of a North-German breeding Company were recorded. Estimated genetic correlation between purebred and crossbred Performance were rg = 0.59 and 0.40 for reciprocal crosses L03xL04 and L04xL03, respectively. Further investigations showed that the genetic correlation is influenced by genotype-environment interactions between a nucleus farm and a farm on production level. Full-sib effects showed a proportion of FS = 0.06 on the phenotypic variance of litter size. They were confounded with additive genetic variance and permanent environment variance, when full-sib effects were neglected. The percentage of equal selected purebred sires of line L03 were 80% when 30% of the sires selected on purebred or crossbred breeding values. Accuracy of estimated breeding values of purebred sires increased when crossbred Information were considered additionally from 0.32 to 0.38 for line L03 and 0.46 to 0.47 for line L04. Genetic correlation between purebred and crossbred Performance, the genetic connectedness between nucleus and production and the presence of genotype-environment interactions were analysed to have high influence on the value of additionally considered crossbred Performance.

Abstract. Title of the paper: Growth and development quality of dairy calves reared in groups with an automatic milk feeder. Physiological variables and their changes at specific age periods On 38 dairy calves (20 male, 18 female) measurements of growth Performance and of body temperature (RT) and blood sampling were made at 15, 30, 60 and 90 days of age of the calves. Blood was analysed for acid-base balance, biochemical and hematological values, minerals and hemoglobin derivatives. Effects of season (groupl: calvings from October tili December; group 2: calvings from January tili April) and of gender were considered. Growth Performance was different between the groups at all age points. Group effects existed at 15 days (RT, Hk, MetHb, Laktat, P), at 30 days (RT, P), at 60 days (Hb, O2CAP, pH, BE, HCO3, P), at 90 days (pCO2, blood urea, Mg, Fe). Gender effects became obvious at 30 days (O2CONT, O2SAT, MetHb, HHb, pCO2). Interactions of group and gender occured at 15 days (P), at 30 days (O2CONT, pCO2), at 60 days (COHb, Mg) and at 90 days (Hb, O2CAP). Between age point mean differences could be found for acid-base Status, total protein, albumin, Creatinine, blood urea, glucose, Mg and for the hematological variables. In most cases between age point changes of variables showed strong negativ correlations with the starting values at 15 days of age. Directed changes of most variables within life age periods developed with different degrees depending on development quality and on specific husbandry conditions.

Abstract. Production and reproduetive traits in Danish Landrace (LD) and Large White (LW) swine were analysed by restricted maximum likelihood methods to obtain heritabilities as well as genetic and phenotypic correlations. Production traits were: age, backfat thickness (BT), muscle depth (MD) and the ratio BT/MD, adjusted to Standard bodyweight of 85 kg. Reproduction traits were: number of pigs born (NB) and number of pigs weaned (NW) per sow and parity. Heritabilities for age, BT, MD and BT/MD were 0.60, 0.44, 0.51 and 0.42 for LD and 0.36, 0.44, 0.37 and 0.45 for LW, respectively. Genetic correlations between age and BT were −0.22 in LD and – 0.44 in LW. The genetic correlation between age and MD was close to zero in both breeds. Genetic correlation between BT and MD were −0.36 and −0.25 in LD and LW, respectively. Heritabilities for NB were 0.25 in LD and 0.13 in LW while heritabilities for NW were close to zero in both breeds. Genetic correlation between NB and NW was 0.46 and 0.70 in LD and LW, respectively.

Abstract. The effect of addition ofvitamin E (a-tocopherol) to pig diets on muscle metabolism of phosphorus Compounds, ATPase activity and meat quality was studied. Experimental pigs were fed with a diet supplemented with vitamin E (200 mg α-tocopherol/kg diet) for 60 days before slaughtered (110 kg live weight). Longissimus muscle (LD) Vitamin E level was more than twice higher (P < 0.01) in pigs supplemented with vitamin E Changes of muscle phosphorus Compounds like sugar phosphate (SP), inorganic phosphate (Pi), phosphoereatine (PCr), and adenosinetriphosphate (ATP) assessed by 31P NMR spectroscopy (15 min post mortem) differed between control pigs and vitamin E administered pigs. Significantly lower (P < 0.05) values of SP and significantly higher values of PCr were found in pigs administered with vitamin E. Efficiency of muscle energetic metabolism measured as index PCr/Pi was higher in pigs supplemented with vitamin E. ATPase activity of longissimus muscle (LD) was not influenced by vitamin E in diet. Drip loss of LD measured 24 h post mortem and conduetivity of semimembranosus (SM) and LD measured 3 h post mortem (P < 0.05) improved by administration with vitamin E. Differences between pH of LD and SM muscles measured 45 min post mortem were not significantly influenced. Dietary vitamin E administered for 60 days to finishing pigs may have beneficial effects on muscle energetic metabolism, electrical conduetivity, and drip loss.

Abstract. Birth weight (BW), weaning weight (WW), yearling weight (YW) and seven body measurements (cannon bone length at birth (CB); hip height at weaning (HHW); hip height at yearling (HHY); body length at weaning (BLW); body length at yearling (BLY); scrotum circumference at weaning (SCW) and scrotum circumference at yearling (SCY), measured in a Hereford stud (1497 animals) over a period of 19 years, were used in estimating genetic (co)variances, heritabilities and correlations. Nine different multitrait animal model evaluations were carried out whereby (co)variance components were estimated using the REML VCE 3.0 package. Estimates from different evaluations were pooled, weighing each estimate by the inverse of the sampling variance to calculate weighted mean variance ratios among the different traits. Generally, structural traits tended to have lower heritability estimates (CB = 0.24; HHW = 0.28; HHY = 0.33; BLW = 0.22; BLY= 0.14 ) when compared with literature values , while estimates for production traits compared well with estimates reported for the South African National Evaluation. Weights and linear body measurements were positively correlated (0.4−0.9). Negative correlations were found for scrotum, circumference at weaning and yearling with BW and CB respectively. SCW and BW: −0.54; SCY and BW: −0.65; SCW and CB: −0.66; SCY and CB: −.58. It is concluded that CB could serve as an early indicator of mature size and weights at different ages.

Abstract. During the laying period the changes in concentrations of plasma total lipids, cholesterol, glucose and urea were studied in the RIW laying line selected for the number of eggs laid during the eight month laying period. The feed mixtures were changed qualitatively causing both changes in plasma lipaemia, glycaemia and uremia and time-limited reduction in the body weight and laying intensity. Average concentrations of the individual blood indicators of the entire group of hens during the laying period ranged as follows: total lipids 5.06 ± 0.63 g.l−1 to 21.51 ± 5.28 g.l−1, cholesterol 1.99 ± 0.45 mmol. l−1 to 4.73 ± 1.54 mmol. l−1, glucose 4.43 ± 0.51 mmol .l−1 to 19.02 ± 5.25 mmol.l−1 and urea 3.53 ± 0.98 mmol.l−1 to 6.29 ± 2.51mmol.l−1. The concentrations of the given biochemical indicators were also studied to contrast at the age of 25 weeks in other lines of hens originating from the RIW and BPR lines. The average values of all the studied indicators were different in lines of different laying intensity and earliness (fed the same feed mixture in the same hall), i.e. total lipids 25.00 ±7.51 to 45.85 ± 11.98 g.l−1, cholesterol 3.25 ± 0.85 to 4.83 ± 0.81 mmol.l−1, glucose 11.91 ±2.69 to 15.15 ± 1.98 mmol.−1 and urea 3.08 ± 0.53 to 6.90 ± 1.61 mmol.l−1. We can say that during the laying period important changes in plasma lipaemia, glycaemia and uremia of the hens occur in dependence on changes in the feed mixture or in its quality too. These criteria monitor the level of interaction between the genotype and the environment on the level of pre-clinical response of the organism.

Abstract. Title of the paper: Considering health traits in breeding ofsport horses In breeding sport horses Performance and health traits are equally important to exhaust the horses' Performance potential. The need to consider health traits and to produce sound horses follows also from animal welfare and economic aspects. Often horses not successful in competitions are used in breeding. The time length of active participation in competitions and the reproductive Performance of horses are negatively affected by several diseases. Main causes are diseases of locomotor and respiratory organs whereby osteochondrosis dissecans and hemiplegia laryngis are the most frequent ones. These diseases have a sufficiently high heritability and can be selected for. In contrast, reproductive traits in horses have a very low heritability as found in other species. In defining selection policies to improve the health Status other factors besides heritability have to be considered such as way of inheritance, frequency of incidence and economic importance. In future the identification of defect genes may help in exactly diagnosing health problems and in breeding for sound Constitution. First actions to be taken by breeding organizations relate to testing early progenies. But also actions to improve nutrition, husbandry and training in rearing are important to reduce incidence and relevance of health problems in sport horses.

Abstract. Title of the paper: Genetic analysis of the course of individual growth and feed intake of group-penned Performance tested boars Objective of the study was to analyse the course of feed intake and growth of 661 boars of three lines (259, 208, and 194 animals of lines 3, 4, and 8, respectively) during an age dependent Performance test between the 100th and 170th day of age. Individual feed intake of the group-penned animals was recorded by electronic feeding stations during the first, third, fifth, seventh, and ninth week on test. Additionally, each animal was weighted in biweekly intervalls. A second order polynomial and a third order polynomial were individually fitted on feed intake and live weight. From these curves, individual information about daily feed intake, daily gain, and food conversion ratio were derived for five periods of 12 days and for the entire period. Genetic parameters were estimated simultaneously using a multiple trait animal model. Heritabilities of h2 = .50, .55, .40, and .39 for traits of entire test period were found for backfat thickness, daily gain, daily feed intake, and food conversion ratio, respectively. Estimated heritabilities for each test period from one to five were h2 = .50, .56, .54, .50, and .37 for daily gain, h2 = .18, .43, .46, .45, and .38 for daily feed intake, and h2 = .34, .42, .46, .44, and .39 for food conversion. The genetic correlation between daily gain and food conversion in period one (rg = −.84) was significantly different from correlations between these traits in the following periods (rg = −.32 to −.51). Genetic correlations between daily gain and daily feed intake in each period were rg = .56 to .42 from first to last period. Except of first period (rg = −.11), the genetic associations between food conversion and daily feed intake for periods were similar (rg = .52 to .56). The genetic associations indicate, that a high feed intake in the beginning of the fattening period is desirable, while afterwards a more reduced feed intake should be achieved to improve efficiency of fattening Performance. In order to optimise fattening Performance, the use of part test information from growth rate and feed intake is necessary.

Abstract. Title of the paper: Colour brightness L*, haem pigment and iron content in the musculus longissimus dorsi at Thuringian pig origins To the Identification of the Situation at the meat quality trait „meat colour" were the colour brightness L*, the reflection spectrum between 400 and 750 nm, the haem pigment content and the iron content at the musculus longissimus dorsi of 278 pigs from the Thuringian Performance testing center determined. While at the colour brightness L* measuring 24 h post mortem 90 % of the animals corresponded to the quality requirements at intact muscles the same samples of minced meat measuring 25 h post mortem presented a lower level of colour brightness L* predominantly. The haem pigment as well as the iron content (n = 104) showed means average values (1,06 mg/g resp. 4,18 mg/kg) which were too low in comparison with bibliographical references.The reflection at 525 nm was correlated with R = 0.7 to the extractive determined haem pigment content,
