INTRODUCTION The demand for high quality meat and the competition with other protein sources imposes the introduction of new technologies in the Brazilian beef cattle system of production. Most of breeding evaluation programs in Brazil, have given emphasis to records of weights and scrotal circumference (SC) at different ages, ignoring carcass traits (CT) and other growth traits. Carcass traits...
Heterosis effects for birth weight, ADG from birth to weaning, 200-d weight, ADG from weaning to 368 d, 368-d weight, 368-d height, 368-d condition score, and 368-d muscling score (males only) were evaluated separately for each sex in F1, F2, and combined F3 and F4 generations in three composite beef cattle populations. Breed effects were evaluated for the nine parental breeds (i.e., Red Poll [...
The objective of this study was to determine the relative contributions of Piedmontese inheritance (0, 25, 50, or 75%) and myostatin genotype (+/+, mh/+, and mh/mh) to tenderness of four major muscles. Matings were made to produce animals with 0 (+/+), 1 (mh/+), or 2 (mh/mh) inactive myostatin alleles that were known to result in normal muscling, heavy muscling, and extremely heavy muscling, re...
Molecular biology has enabled the identification of the mechanisms whereby inactive myostatin increases skeletal muscle growth in double-muscled (DM) animals. Myostatin is a secreted growth differentiation factor belonging to the transforming growth factor-β superfamily. Mutations make the myostatin gene inactive, resulting in muscle hypertrophy. The relationship between the different character...
