title: Residual intake and gain for the evaluation of performance, non-carcass components, and carcass characteristics of confined crossbred Texel lambs

description: ABSTRACT We evaluated performance, non-carcass components, and carcass characteristics of crossbred Texel lambs in different categories of residual intake and gain (RIG). We assessed 77 crossbred (¼ Pantaneira and ¾ Texel) non-castrated animals in two study phases. The first phase included 47 lambs with an initial average weight of 29.9±5.5 kg, and the second phase included 30 lambs with initial average weight of 22.4±3.3 kg. Dry matter intake (DMI) and average daily gain (ADG) were evaluated for 70 days. Animals were divided into three groups in terms of efficiency: efficient (high RIG), intermediate (medium RIG), or inefficient (low RIG), based on the standard deviation of the mean for the RIG variable. We measured the yield of non-carcass components, carcass characteristics, and yield of meat cuts. Efficiency group had no association with DMI, nor with initial and final body weights of the animals. The ADG of efficient (0.310 kg day−1) and intermediate (0.290 kg day−1) animals was greater than observed in inefficient (0.260 kg day−1) animals. Lambs in the efficient and intermediate groups had significantly higher levels of all efficiency indicators evaluated. Efficient and intermediate animals yielded significantly more wool/skin in comparison with lambs in the inefficient group. Animals with high RIG also had lower relative weight of testicles/scrotal sac in comparison with inefficient animals. Fat deposition in the omentum and mesentery as well as total fat were decreased in efficient animals. No significant differences occurred among groups regarding carcass characteristics and yield of meat cuts. The RIG index allows for the identification of lambs with higher growth rates and greater wool/skin yield and lower proportion of visceral fat.

title: Performance and carcass characteristics of broilers fed whole corn germ

description: ABSTRACT The objective of this study was to evaluate the effect of including whole corn germ (WCG) on the performance; diet metabolizability; yields of carcass, cuts, and offal; and quality of meat of broilers. A total of 648 chicks were assigned to six treatments in a completely randomized design with six replicates, with 18 birds in each. Treatments consisted of a corn- and soybean meal-based control diet (0 g kg−1 WCG) and five test diets including WCG at the levels of 40, 80, 120, 160, and 200 g kg−1. Birds and diets were weighed at each seven days to determine feed intake (FI), body weight gain (BWG), and feed conversion ratio (FCR). The partial collection methodology was employed to determine the apparent metabolizable energy (AME), nitrogen-corrected AME (AMEn), and the apparent metabolizability coefficients of gross energy (AMCGE), dry matter (AMCDM), crude protein (AMCCP), and ether extract (AMCEE) of the diets. In the evaluation of meat quality, we analyzed the pH, cooking losses, shear force, water-holding capacity, color, and peroxide index of the meat. There was a difference for BWG and FCR in the total rearing period (1 to 42 days), for which optimum BWG was estimated as 2921 g/bird, with 118 g kg−1 inclusion of WCG. There was no difference for the AME, AMEn, and AMCCP of the diets, although AMCGE, AMCDM, and AMCEE declined as WCG was included. The increasing levels of WCG did not influence the yields of carcass and cuts or the meat quality. There was an increase in the yield of gizzard and proventriculus. Whole corn germ can be used at low levels in the diet of broilers without compromising their productive rates.

title: Quantification of floral abnormalities in a population generated from sexual polymorphism aiming at recurrent selection in papaya

description: ABSTRACT The aim of this study was to estimate the percentage of deformed fruits (carpelloid, pentandric, and bananoid), summer sterility, repeatability coefficients, and correlations among the variables for floral abnormalities; and select genotypes withthe lowest incidence of deformed fruits and summer sterility. In theexperiment, which involved 254 plants, traits were evaluated using the digital-phenotypic method and the obtained images were processed and analysed using ImageJ v1.48 software with the Cell Counter plugin. Summer sterility had the highest percentage of occurrence in the evaluated periods. Based on the quantificationof total abnormalities, the 30 genotypes with the lowest incidence offloral abnormalities were selected. Summer sterility is the main problem of the papaya crop in terms of floral abnormalities. The non-significant correlations between the traits: NDF/TNF+NFN (number of deformed fruits/number of fruits + number of fruitless nodes) and NFS/TNF+NFN (number of fruitless nodes/number of fruits + number of fruitless nodes); NDF/TNF+NFN and NFN/SUM(number of fruitless nodes/sum of abnormalities); andNFS/TNF+NFN and NDF/SUM (number of deformed fruits/sum of abnormalities) indicate that the variables are independent of each other. Of the 254 evaluated progenies, at least 30 were identified as having potential for selection, with lower occurrence of total floral abnormalities.

title: Production of forage potential of utilization of digit grass subjected to high defoliation frequencies

description: ABSTRACT The objective of this study was to evaluate the production of forage and the potential of utilization of digit grass subjected to four defoliation frequencies: very high (25cm), high (35cm), medium (45cm), and low (55cm), evaluated at two times of the year (higher and lower insolation), from January 2015 to January 2016. A randomized-block design with four replicates was adopted and measures repeated over time. The daily production of leaves was lower at the very high frequency in relation to the other frequencies. The reduction in defoliation frequency increased the daily production of stems, the daily leaf senescence, the total daily forage production, and the daily forage accumulation, and decreased the potential of forage utilization. At the time of higher insolation, the daily production of stems, the daily forage accumulation, the potential of utilization of forage were higher, and the daily leaf senescence was lower. The very high frequency of defoliation did not provide a good development of the plan, while the lower frequency displayed a high production of stems. The high and medium frequencies of defoliation are more indicated to the defoliation of digit grass, enabling a better proportion of leaves in relation to stems.

title: Antimicrobial resistance profile of Klebsiella pneumoniae isolated from domestic and wild animals

description: ABSTRACT Klebsiella pneumoniae is an opportunistic pathogen responsible for several types of nosocomial infections and is considered a multiresistant microorganism. Data in the literature that provide information regarding the resistance of this microorganism to antimicrobials in animal samples are scarce. Thus, the objective of this work was to evaluate the profile and its increase of antimicrobial resistance within Veterinary Medicine. A total of 67 K. pneumoniae isolates from different domestic (39/67) and wild (28/67) isolation sites were confirmed by sequencing the 16S rRNA gene. The highest percentage of K. pneumoniae isolation was from urine samples with 16% (11/67), faeces 15% (10/67) and lung 13.5% (09/67). In the resistance profile, 11 categories of antibiotics were tested, with the highest resistance to metronidazole being 97% (65/67), ampicillin 94% (63/67), amoxicillin 93% (62/67), sulfonamides 93% (62 / 67), 93% colistin (62/67), and 88% nitrofurantoin (59/67). The ones with the lowest resistance were: meropenem 3% (2/67), imipenem 6% (4/67) and amikacin 16% (11/67). All isolates were considered multiresistant bacteria (MDR), with the Multiple Resistance to Antibiotics Index (IRMA) ranging from 0.15 to 0.85 and with 60 types of resistance patterns. The result of this study reinforces that the animals are reservoirs of multiresistant K. pneumoniae.

title: Multivariate analysis of morphometry effect on race performance in Thoroughbred horses

description: ABSTRACT The objective of this study was to determine the effects of morphometric measurements on race performance (m/sec) of Thoroughbred horses. Data of morphometric measurements (withers height, rump height, chest girth, chest width, front chest width, chest depth, neck length, shoulder length, length of withers to rump, rump length, body length, head width, head length, and cannon circumference) were taken from 244 Thoroughbred horses chosen at random. A total of 2888 racing records were considered for race performance. The effects of environmental factors on morphometric measurements (stallion, gender, age, and mother age) and race performance (gender, age, mother age, year, hippodrome, race distance, racetrack, and race type) were analyzed using the least squares method. Principal component analysis (PCA) was performed for morphometric measurements, and then the factor loadings were rotated by Varimax method. Multiple linear regression analysis was applied for the significance of the obtained factors on race performance. Significant effects for stallion on all morphometric measurements, except head length and width, and for gender on withers height, cannon circumference, and head width were determined. Race performance was significantly influenced by stallion, gender, age, year, hippodrome, race distance, racetrack, and race type. After PCA, four factors with eigenvalues &gt;1 were attained. The effects of factors on race performance were not significant, according to the results of multiple linear regression analysis. Therefore, the effects of the morphometric measurements examined on the race performance were not significant in Thoroughbred horses.

title: Left Atrial Stiffness: A Predictor of Atrial Fibrillation Recurrence after Radiofrequency Catheter Ablation - A Systematic Review and Meta-Analysis

description: Abstract Background: Radiofrequency catheter ablation (RFCA) is a standard procedure for patients with atrial fibrillation (AF) not responsive to previous treatments, that has been increasingly considered as a first-line therapy. In this context, perioperative screening for risk factors has become important. A previous study showed that a high left atrial (LA) pressure is associated with AF recurrence after ablation, which may be secondary to a stiff left atrium. Objective: To investigate, through a systematic review and meta-analysis, if LA stiffness could be a predictor of AF recurrence after RFCA, and to discuss its clinical use. Methods: The meta-analysis followed the MOOSE recommendations. The search was performed in MEDLINE and Cochrane Central Register of Controlled Trials databases, until March 2018. Two authors performed screening, data extraction and quality assessment of the studies. Results: All studies were graded with good quality. A funnel plot was constructed, which did not show any publication bias. Four prospective observational studies were included in the systematic review and 3 of them in the meta-analysis. Statistical significance was defined at p value &lt; 0.05. LA stiffness was a strong independent predictor of AF recurrence after RFCA (HR = 3.55, 95% CI 1.75-4.73, p = 0.0002). Conclusion: A non-invasive assessment of LA stiffness prior to ablation can be used as a potential screening factor to select or to closely follow patients with higher risks of AF recurrence and development of the stiff LA syndrome.

title: Evaluation of two point-of-care tests to diagnosis of FIV and FeLV infections

description: ABSTRACT FIV and FeLV are Retrovirus associated mainly with feline neoplasms. Two point-of-care tests are commercially available in Brazil for diagnosis of these infections: a bidirectional flow immunochromatography kit (IDEXX SNAP ® Combo) and a lateral unidirectional flow immunochromatography kit (ALERE/BIONOTE Anigen Rapid). The aim of this study was to compare SNAP ® and ALERE tests. Blood samples obtained from 178 cats were evaluated using both tests. Quantitative real-time polymerase chain reaction (qPCR) was used as confirmatory test for all samples. The sensitivity and specificity of SNAP ® test was 100% for FIV, and for ALERE test was 96.15% and 98.68%, respectively. The sensitivity and specificity for FeLV was 93.02% and 96.30% for SNAP ® test and 90.70% and 97.78% for ALERE test. Three samples with a qPCR positive result for FeLV obtained a false negative result in both SNAP ® and ALERE tests. There was no statistically significant difference between the two methods. Considering qPCR as gold standard method, the SNAP® test showed higher sensitivity and specificity for FIV, and the ALERE test presented higher specificity for FeLV. The results showed good agreement among the tests.

title: Wood-decay fungi (Agaricomycetes, Basidiomycota) in three physiognomies in the Savannah region in Brazil

description: ABSTRACT This study was carried out aiming at determining whether the following factors are related to the diversity of wood-decay fungi: cerrado physiognomies, vegetation diversity (availability of substrates), preservation status of the area and its management backgrounds, and the existence of rivers nearby (humidity). 796 specimens were collected in four areas: one in the cerrado sensu stricto, one in the semi-deciduous forest and two in the riparian forest (one more preserved and the other less preserved). A total of 92 species of fungi were identified. Eleven species are common in the four areas sampled and 30 species occurred only once during the two-year sampling. Higher richness and abundance were observed in the more preserved area of riparian forest. This study showed that in the same macroclimate, the Agaricomycetes diversity is influenced by the vegetation’s physiognomy and diversity related to the soil characteristics, humidity, and conservation level of the area.

title: Analysis of the compressive strength of concrete with addition of ash from landfill

description: ABSTRACT The objective of this work is to identify the behavior of some traces of concrete in which there is the partial replacement of the natural sand by the landfill ash. Four traces were proposed, the first one with 100% natural sand, which will be used as reference traces, the second with 5% ash from the landfill, in relation to the natural sand mass, the third with 10% ash, the room with 15% ash. The traces of the concretes were composed of cement, sand / ash, gravel and water, and these were tested for their compressive strength. The results showed that the composite traces with ash showed good performance with respect to the compressive strength. The relevance of this study is due to the fact that landfills, when used the process of burning the garbage, produce ashes, causing an impact on nature that generates an important environmental liability. Therefore, the use of this type of waste makes it possible to reduce this environmental impact.
