title: Effect of Ultra-fine Traditional Chinese Medicine Compounds on Regulation of Lipid Metabolism and Reduction in Egg Cholesterol of Laying Hens

description: ABSTRACT This study has the objective of investigating the effects of traditional Chinese medicine prescriptions (TCM) on serum lipid, abdominal and hepatic fat percentage, cholesterol content in eggs, and mRNA expression of genes apoA I and apoB100. One hundred and thirty five healthy (300-day-old) layers were randomly assigned to three treatments. The hens in control group were fed with the basal diet. The hens in the experimental groups (TCM 1 and TCM 2) were fed with the basal diet supplemented with 1% TCM 1 and 1% TCM 2 respectively over a period of 60 days. Laying performance and the serum parameters relevant to fat metabolism were measured. The results showed that no significant differences were found in average daily feed intake and egg weight among three treatments. Average daily laying rate in TCM treatments was increased, and the cholesterol content in eggs was decreased. The serum triglyceride (TG), total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) levels in experimental treatments were decreased (p&lt;0.05), while the serum high-density lipoprotein cholesterol (HDL-C) level was increased (p&lt;0.05) compared to the control group. Additionally, abdominal fat percentage decreased in TCM 1 treatment (p&lt;0.05), and hepatic fat percentage decreased in both TCM treatments (p&lt;0.05). The expression of apolipoproteinA I (apoA I) and apolipoproteinB100 (apoB100) mRNA in the liver increased in both TCM treatments (p&lt;0.05). These results suggest that the diet supplemented with TCM could increase the expression of apoA I and apoB100 mRNA in the liver, and decrease lipid content in the serum, and reduce egg cholesterol in layers.

title: COMPUTATIONAL CHEMISTRY EMPLOYMENT IN VERIFICATION AND VALIDATION OF DETONATION PRESSURE OF PLASTIC EXPLOSIVE - PBX

description: Prediction of chemical explosions parameters is an important step for blast tests for civil and military applications. Applying computational chemistry and experimental results, this paper presents the decay rate of pressure in air from the epicenter of 2.70 kg of PBX-Plastic bonded explosive detonation to the distance of 2.0 meters. Pressure in the epicenter was calculated using reactive molecular dynamics simulations and the incident pressure at 1.3; 1.6 and 2.0 meters were measured with piezoelectric pressure sensors. The explosive for the full-scale test were non-confined in a cylindrical shape. Results of simulation and recorded values were consolidated and the rate of pressure decay was verified by statistic regression. Good agreement was verified between computational and experimental pressures data. This research can help designers to prepare protection devices in test areas, storages of explosives or important buildings for military proposes.

title: Proposal for Prediction of Wind Speed through Hybrid Modeling Elaborated from ARIMAX and ANN Models

description: Abstract In this paper, a hybrid model capable of predicting wind speed (monthly and hourly averages) with good accuracy in regions of the Brazilian Northeast. This model is elaborated from the combination of two models, the Auto-Regressive Integrated Moving Average with eXogenous inputs (ARIMAX) and Artificial Neural Networks (ANN). The choice for these models was motivated by the fact that they can incorporate both linear (ARIMAX) and nonlinear (ANN) features commonly found in time series. The hybrid model correlates pressure, temperature and precipitation with wind speed in order to consider important local meteorological characteristics. It is possible to verify the efficiency of the hybrid model to provide good adjustments to the observed data of the winds speeds, being this affirmation based on the values found by means of accuracy measurements, with average percentage error of approximately 5.0%, and coefficient value of Nash-Sutcliffe efficiency of 0.96. These results confirm the existence of precision for the winds speeds predicted following the profile of their observations, in particular it is possible to identify similarities between both time series (in terms of maximum and minimum values), thus showing the capacity of the model in represent characteristics of seasonality.

title: Duration of co-feeding on the Nishikigoi Cyprinus carpio larvae during weaning from live to inert food in an indoor system

description: ABSTRACT: This study aimed to evaluate the effects of the co-feeding period (C) on the survival and growth of larvae of nishikigoi Cyprinus carpio, during the weaning period from live to inert food. A total of 1680 larvae with initial weight of 1.33 ± 0.12mg and initial length of 6.0 ± 0.33mm were used. The inert diet used was a commercial ration with 55% crude protein and the live food was the newly hatched nauplii of Artemia franciscana. The experiment was conducted following a completely randomized design with six treatments and four replications. Treatments constituted of: a) LF = supply of live food throughout the experimental period; b) C4 = 6 days of live food + 4 days of co-feeding (inert diet and live food) + 16 days of inert diet; c) C8 = 6 days of live food + 8 days of co-feeding + 12 days of inert diet; d) C12 = 6 days of live food + 12 days of co-feeding + 8 days of inert diet; e) IF = supply with inert diet throughout the experimental period; and f) F = fasting. Our results showed that the co-feeding period influences the survival and growth of the larvae. Survival in the treatment with the longest co-feeding period showed an improvement of over 70% when compared to the shortest period. Further, we noted a doubling of the juvenile weight after 26 days of age. There was a quadratic effect for all parameters, with maximum points ranging between 19.4 and 22.6 days of supply of live food. We concluded that the supply of commercial feed as exclusive food is unworkable in nishikigoi larviculture.

title: Gender and live weight on carcass and meat characteristics of donkeys

description: ABSTRACT: One hundred eighty-nine Catalan crossbreed donkeys (Equus africanus asinus) were used to evaluate the effect of gender (gelding, n=106; or female, n=83) and live weight at slaughter (LW) (&lt;100kg, n=25; 101 to 125kg, n=42; 126 to 150kg, n=85; and 151&gt;kg, n=37) on carcass characteristics, non-carcass components and meat and fat color. Geldings had greater (P&lt;0.05) carcass weight, carcass dressing and *L value of subcutaneous fat than females; but females had greater (P&lt;0.05) cooling loss, a* value of semitendinosus muscle and b* value of subcutaneous fat. Donkeys with more than 126kg of LW showed greater (P&lt;0.05) carcass weight and dressing and lower (P&lt;0.05) cooling loss compared to lighter donkeys. The a* value of semitendinosus muscle and abdominal fat was greater in heaviest donkeys (&gt;151kg). Meanwhile, the LW did not affect the color (L*, a* and b* values) of subcutaneous fat (P&gt;0.05). These results suggested that both gender and live weight should be considered when producing meat from donkeys. It is advisable to use geldings weighing more than 126kg at slaughter to obtain the greatest weight and carcass yield.

title: Formation of homogeneous groups of bovine milk production units via multivariate statistical techniques

description: ABSTRACT: Milk supply chain in Brazil exhibits significant production system heterogeneity in all federal units. Thus, the objective of this study was to form homogeneous groups of bovine milk production units based on the chemical and microbiological quality of the milk via multivariate statistical techniques. A total of 1,541 milk producing units (MPUs), corresponding to 44,089 samples, were analyzed. The first three principal components accounted for 81.38% of the total variation in the data. Principal component 1 (PC1) was associated with the chemical quality of milk (fat, protein [PROT] and total dry extract [TDE] content), while PC2 and PC3 were associated with microbiological quality (somatic cell count [SCC] and total bacterial count [TBC]). The concurrent analysis of the two two-dimensional projections characterized the different productive strata by their quality attributes and identified the positive/negative points of milk microbiological characteristics in each production group. Thus, the dimensionality of the set of 1,541 MPUs was reduced to 15 homogeneous production groups. This method optimizes the use of the dairy industry monthly database and characterizes all the heterogeneities present in dairy production systems.

title: Performance and feed intake of beef heifers on rotational grazing of natural grassland receiving protein and energy supplement in cool season

description: ABSTRACT: The aim of this study was to evaluate the performance and feed intake of grazing beef heifers on two grazing intervals determined by thermal sum related to leaf elongation duration during cool season on natural grasslands. A complete randomized block design experiment with two treatments and three replications was conducted from May to September 2011 in the central part of the state of Rio Grande do Sul, Brazil. The treatments were two thermal sums calculated at 375 and 750 degrees-days (DD) to determine the intervals between grazing periods in a rotational grazing system. Thirty six beef heifers with average age of 18 months old and (initial body weight = 220±14kg) were used, all heifers received ground corn supplement at a rate of 5g kg-1 of body weight per day, at 2p.m., throughout the experiment and had free access to mineral and protein supplementation (450g kg-1 of CP). Similar average daily gain (ADG), beef production gain (BPG) and feed intake (FI), were obtained in both treatments. Leaf elongation duration is an alternative grazing management tool for improved animal production and to increase animal stocking rate.

title: MORPHOLOGIC CHARACTERIZATION OF GUAVA GERMPLASM FROM MÉXICO: IMPLICATIONS ABOUT ITS CONSERVATION AND BREEDING

description: ABSTRACT Guavas (Psidium guajava L.) growing throughout Mexico show broad morphologic and productive variation due the crop is commonly sexual-propagated. The characterization of genetic diversity of Mexican guava germplasm will allow identify potential parents for genetic improvement as well as the production of new clonal cultivars. In this work 88 guava accessions [87 belong to P. guajava and one from P. friedrichsthalianum (Berg.) Niedz] growing in Huanusco, Zacatecas Mexico were characterized on the basis of 50 morphologic descriptors. The 95% of germplasm shows ovoid or round fruit shape; 92% fruits with beige or white mesocarp and 87.5% has yellow fruits. Fruits with these traits are locally named as ‘China’ or ‘Media China’ and they are preferred for fresh use. Seven quantitative traits were those that better described the morphologic variability of germplasm: two from trees (stem thickness and leaf length) and five from fruits (polar and equatorial diameter; sepal size; calyx cavity diameter; and total solid soluble content). Three accessions (numbers 68, 52, and 49) outstand due their high values of tree growth under field conditions although showing small fruit sizes while other five accessions (numbers 79, 57, 60, 78, and 56) exhibited small tree sizes but high values for fruit, sepals and calyx cavity, and total solid soluble contents.

title: Characterization and Marmelade processing potential of quince cultivars cultivated in tropical regions

description: Abstract With the purpose of adding value to the final product and aiming to identify which cultivars implanted in tropical regions are more appropriate for the processing of marmelade, the objective of this study was to characterize and evaluate the influence of different cultivars of quince (‘Fuller’, ‘Smyrna’, ‘Portugal’, ‘Provence’, ‘Mendonza Inta-37’, ‘Alaranjado’, ‘Lajeado’, ‘CTS 207’, ‘D’Angers’ and ‘Bereczy’) grown in tropical Brazilian regions, on the physical-chemical characteristics, rheological properties and the consumer acceptance of the obtained marmelade. The different quince cultivars presented great variability among themselves in relation to physical and physicochemical characteristics. However, the cultivars studied gave rise to marmelades that were similar to each other, which had a high sensory acceptance, except for the cultivar Mendonza Inta-37, which resulted in a less accepted marmelade.
