The commercial value of the bovine carcass is determined by a set of traits, such as weight, yield, back fat thickness, and marbling; therefore, the genetic improvement of growth, meat, and carcass quality traits is an important tool to add value to the supply chain. Genomewide association studies (GWAS) enable the identification of loci that control phenotypic expression of quantitative traits (QTL). Therefore, the objective of this work was to perform a GWAS to identify genomic regions and genes associated with growth, carcass traits, and meat quality in Canchim beef cattle. These traits were yearling weight (YW), rib eye area (REA), back fat thickness (BFT), and marbling (MARB). To increase sample size and marker density, genotype imputation was performed, and only markers imputed with greater than 95% accuracy were used. Genomewide association study was performed using a Bayesian approach, by the Bayes B statistical method, incorporating genotypes and phenotypes from 614 animals from both the Canchim breed and the MA genetic group (offspring of Charolais bulls and one-half Canchim + one-half Zebu cows). This investigation identified 1 and 4 genomic regions explaining 0.23 and 7.35% of the genetic variance for REA and YW, respectively. These regions harbor a total of 19 genes, 7 of which were classified for biological functions by functional analysis. Significant associations were not observed for BFT and MARB. The identification of QTL that had been previously described in the literature reinforces associations found in this study.

ABSTRACT - The objective of this work was to evaluate the contamination by Salmonella sp. and enterobacteria in pig carcasses from the first and last
batches slaughtered in a same week, at different stages of the slaughtering line. Samples were collected from the first and last batches slaughtered on
Monday and Friday of each week, respectively, during five weeks, totaling ten batches. From each batch, ten carcasses were collected in eight stages of
the slaughter line: bleeding, scalding, singeing/evisceration, inspection, spinal cord removal, final washing, blast chilling, and after cooling. A total of 800
samples were analyzed for Salmonella sp. and enterobacteria quantification. The last batch of the week showed twice the chances of the pig carcasses being contaminated with Salmonella sp. and, consequently, a greater amount of enterobacteria (1.00 log10 CFU per square centimeter) than the first batch (0.88 log10 CFC per square centimeter). A higher count of enterobacteria was also observed in the stages of bleeding (2.37 log10 CFU per square centimeter) and scalding (2.36 log10 CFU per square centimeter). The last batches slaughtered in the week show a greater contamination than the first ones, and there is a greater contamination of carcasses by Salmonella sp. and enterobacteria in the initial stages of pig slaughter, i.e., at bleeding and scalding.
RESUMO - O objetivo deste trabalho foi avaliar a contaminação por Salmonella sp. e enterobactérias em carcaças suínas do primeiro e do último lote abatido na mesma semana, em diferentes etapas da linha de abate. Foram coletadas amostras do primeiro e do último lote abatido na segunda e na sexta-feira de cada semana, respectivamente, durante cinco semanas, o que totalizou dez lotes. De cada lote, foram coletadas dez carcaças, em oito etapas da linha de abate: sangria, escaldagem, chamuscador/evisceração, inspeção, retirada da medula espinhal, lavagem final, choque térmico e
refrigeração. Um total de 800 amostras foi analisado para quantificação de Salmonella sp. e enterobactérias. O último lote da semana apresentou duas
vezes mais chances de as carcaças estarem contaminadas com Salmonella sp. e, consequentemente, maior quantidade de enterobactérias (1,00 log10 UFC por centímetro quadrado) que o primeiro lote (0,88 log10 UFC por centímetro quadrado). Uma quantidade maior de enterobactérias também foi observada nas etapas de sangria (2,37 log10 UFC por centímetro quadrado) e escaldagem (2,36 log10 UFC por centímetro quadrado). Os últimos lotes abatidos na semana apresentam contaminação maior do que os primeiros, e há maior contaminação das carcaças suínas por Salmonella sp. e enterobactérias nas etapas iniciais do abate de suínos, isto é, na sangria e na escaldagem.
