“…Clearly the heritability for meat tenderness can present substantial variation even among animals of the same breed. Other reports in the literature also demonstrate heritabilities ranging from low to high magnitude, whether within or between breeds (BOUKHA et al, 2011;JOHNSTON et al, 2003;MINICK et al, 2004). However, there are few studies that are directly comparable with the results found in this study, because most of the research with gene prospection of meat quality features refers to Bos taurus breeds and their crossbreds with Zebu cattle (ELZO et al, 1998;JOHNSTON et al, 2003).…”

-The aim of the present study was to analyze the interrelationships among the variables and also estimate the genetic correlations between tenderness (WBSF), growth (ILW, FLW and ADG) and carcass (BF, RF and LMA) features. Other purpose was to identify individuals who were more likely to be carriers of favorable genes for tenderness. Growth, carcass and tenderness data from 415 Polled Nellore animals was analyzed. Factor analysis and canonical correlations were used to analyze the phenotypic relationships. The covariance components and genetic parameters were estimated using Gibbs Sampling method. Lack of phenotypical correlations between the WBSF and the other traits were observed. The genetic correlations between WBSF and the other evaluated traits were of a low magnitude, with values of -0.15; -0.18; -0.13; 0.10; -0.12 and 0.18, between WBSF and ILW, FLW, ADG, BF, RF and LMA, respectively. The results support the conclusion that tenderness selection will not affect the selection of other economic traits and vice-versa, but for a better knowledge of the genetic relationships between meat tenderness and other traits for Polled Nellore more studies are required. The heritability estimated for WBSF was of a low magnitude (0.11 ± 0.022). Based on the principle of probability of identical genes by ancestry individuals who were more likely to be carriers of favorable genes for tenderness were identified. Further work will include creation of a segregating population that will serve as experimental material for future gene prospecting and identification research.Key works: Carcass. Shear force.

Foi proposto também, identificar indivíduos que apresentem alta probabilidade de serem portadores de genes favoráveis à maciez. Analisouse dados de 415 animais Nelore Mocho, filhos de touros representativos das principais linhagens Nelore, avaliados para características de crescimento, carcaça e maciez. Para análises de relacionamentos fenotípicos foram utilizadas análises de fatores e correlações canônicas. Os componentes de variância necessários à obtenção dos parâmetros genéticos foram estimados pelo método da Amostragem de Gibbs. Observou-se ausência de correlações fenotípicas entre FC e as outras características produtivas. As correlações genéticas entre FC e PI, PF, GPD, EG, P8 e AOL foram de baixa magnitude (-0,15; -0,18; -0,13; 0,10; -0,12 e 0,18). A seleção para a maciez não influenciará na seleção de outras características de interesse econômico e vice-versa, porém serão necessários mais estudos para melhor conhecimento sobre as relações genéticas da maciez e outras características produtivas em bovinos Nelore Mocho. A estimativa de herdabilidade para a característica FC foi de baixa magnitude (0,11 ± 0,022). Baseando-se no princípio da probabilidade de genes idênticos por descendê...

Association between FTO polymorphism in exon 3 with carcass and meat quality traits in crossbred ducks

et al. 2015

ABSTRACT. The fat mass and obesity-associated gene (FTO) is an excellent candidate gene that affects energy metabolism. Single nucleotide polymorphisms (SNPs) in FTO are associated with carcass and meat quality traits in pigs, cattle, and rabbits. The aim of this study was to investigate the association between novel SNPs in the FTO coding region and carcass and meat quality traits in 95 crossbred ducks, using DNA sequencing. We found two transitions G/A (SNP 387 and 473) within exon 3. SNP 387 was a synonymous mutation, whereas SNP 473 was a missense mutation. Association analysis suggested that SNP g.387G>A was significantly associated with all of the carcass traits measured, the intramuscular fat content (IMF), cooking yield (CY), pH values 45 min after slaughter (pH45m), drip losses from the breast muscle, and the leg muscle (P < 0.05). For SNP g.473G>A, the genotype AA exhibited greater leg muscle weight than the genotypes GG or AG (P < 0.05). The D value suggested that the two SNPs exhibited strong linkage disequilibrium. Three haplotypes (G 1 G 2 , G 1 A 2 , and A 1 A 2 ) were significantly associated with IMF, CY, the a* value, and all of the carcass traits measured (P < 0.05). The results suggest W. Gan et al. 6700©FUNPEC-RP www.funpecrp.com.br Genetics and Molecular Research 14 (2): 6699-6714 (2015) that FTO is a candidate locus that affects carcass and meat quality traits in ducks.

“…Meat quality is commercially important for the animal husbandry industry and is affected by genetic background, management, nutrition and meat processing (Boukha et al, 2011;Cherel et al, 2012). As an exocrine or endocrine protein, prosaposin has important effects on many metabolic processes.…”

<i>PSAP</i> gene variants and haplotypes reveal significant effects on carcass and meat quality traits in Chinese Simmental-cross cattle

Abstract. Prosaposin (PSAP) is the precursor protein of four small lysosomal glycoproteins and plays vital roles in muscle growth and development of beef cattle. The aim of this study is to evaluate the association between PSAP gene polymorphisms with carcass composition and meat quality traits of Chinese Simmental-cross cattle. In the present study, six SNPs were identified within intron 10 and exon 11 of the PSAP gene from 380 beef cattle by direct DNA sequencing, and 47 traits of carcass composition and meat quality were measured in the studied population. Then, the relationship between variants of PSAP gene with economic traits was analyzed using statistical methods. The result revealed that I10-65G > A, I10-313C > T, E11-87C > T, and E11-93C > G were significantly associated with carcass traits, such as dressing percentage, fat coverage rate, carcass depth, and hind leg width, and I10-162C > T and I10-274C > T were significantly associated with marbling score traits. In addition, the individuals with GCCCGC haplotype showed significant higher dressed weight, dressing percentage and rib eye area (p < 0.01), and the individuals with ACCTCC haplotype showed a significant association with the pH of beef and backfat thickness in the cattle population (p < 0.05). Our results indicate that these SNPs and haplotypes of the PSAP gene are possible important genetic factors that influence carcass composition and meat quality traits, and they may be useful markers in future marker-assisted selection (MAS) programs in beef cattle breeding and production.
