Genome-wide association study between copy number variation regions and carcass- and meat-quality traits in Nellore cattle
(Csiro Publishing, 2021-04-27)
Context. Indicine breeds are the main source of beef products in tropical and subtropical regions. However, genetic improvement for carcass- and meat-quality traits in zebu cattle have been limited and genomics studies ...
Relationship between calpastatin gene polymorphism and beef cattle growth, carcass and meat quality traits.
(Amer Soc Animal Science, 2006-01-01)
Frequencies of candidate genes and associations with carcass and meat traits in nellore and crossbred cattle
(2016-02-01)
The objective of this work was to estimate allelic frequencies of the polymorphisms IGF2/MboII (G > T) of the insulin-like growth factor 2 (IGF2) gene, DQ499531.1:g.134A > T of the pro-melanin-concentrating hormone (PMCH) ...
Beef quality of young Angus x Nellore cattle supplemented with rumen-protected lipids during rearing and fatting periods
(Elsevier B.V., 2014-12-01)
This work evaluated the beef quality parameters of 108 bulls randomly administered to three treatments during rearing in pastures and two treatments during fatting in feedlots, including mineral and rumen-protected lipids. ...
Effects of freezing and thawing on microbiological and physical-chemical properties of dry-aged beef
(2020-03-01)
This study evaluated the effects of freezing, prior to and after dry aging, on the microbiological and physical-chemical quality of beef. Strip loins (n = 24) from 12 carcasses were assigned to four treatments: non-frozen ...
Gender status effect on carcass and meat quality traits of feedlot Angus × Nellore cattle
(2019-01-01)
The study evaluated the effect of gender status on carcass and meat quality of feedlot Angus × Nellore cattle. A total of 176 cattle, 20 months old, were confined for 190-days and assigned to four treatments: bulls, ...
Genome-enabled prediction of meat and carcass traits using Bayesian regression, single-step genomic best linear unbiased prediction and blending methods in Nelore cattle
(2021-01-01)
Several methods have been used for genome-enabled prediction (or genomic selection) of complex traits, for example, multiple regression models describing a target trait with a linear function of a set of genetic markers. ...
Effects of supplementation strategies during the growing phase on meat quality of beef cattle finished in different systems
(Elsevier B.V., 2021-05-01)
One hundred and twenty bulls were used in a randomized complete block design in 2 ? 2 factorial arrangement; two supplements during the growing phase: mineral (ad libitum; MIN) or protein + energy [0.3% of body weight ...
Genetic and management factors affecting beef quality in grazing Hereford steers
(Elsevier, 2012-12)
Attributes contributing to differences in beef quality of 206 Hereford steers finished on pasture were assessed. Beef quality traits evaluated were: Warner–Bratzler meat tenderness and muscle and fat color at one and seven ...
Effect of the genetic group, production system and sex on the meat quality and sensory traits of beef from crossbred animals
(2017-08-01)
The crossbreeding of two or more breeds from the Bos taurus and Bos indicus species is an alternative for obtaining high-quality meat from animals adapted to tropical climates. Quality and sensory attributes of beef, mainly ...
