Heritabilities and genetic and phenotypic correlations were estimated from feedlot and carcass data collected from Brahman calves (n = 504) in central Florida from 1996 to 2000. Data were analyzed using animal models in MTDFREML. Models included contemporary group (n = 44; groups of calves of the same sex, fed in the same pen, slaughtered on the same day) as a fixed effect and calf age in days ...
DNA samples from 307 males of 13 Portuguese native cattle breeds, 57 males of the 3 major exotic breeds in Portugal (Charolais, Friesian, and Limousin), and 5 Brahman (Bos indicus) were tested for 5 single nucleotide polymorphisms, 1 "indel," and 7 microsatellites specific to the Y chromosome. The 13 Y-haplotypes defined included 3 previously described patrilines (Y1, Y2, and Y3) and 10 new hap...
The diversity and population genetics of copy number variation (CNV) in domesticated animals are not well understood. In this study, we analysed 75 genomes of major taurine and indicine cattle breeds (including Angus, Brahman, Gir, Holstein, Jersey, Limousin, Nelore, and Romagnola), sequenced to 11-fold coverage to identify 1,853 non-redundant CNV regions. Supported by high validation rates in ...
Cattle production in Cameroon is essentially under a traditional small-scale husbandry management system. The resultant effects are high inbreeding, low fertility, high mortalities of about 5-10% in adult cattle and 20% in calves (Tanya, unpublished results). In an effort to change the situation, the government has put in place a number of programs for cattle production improvement. In 1952 a p...
Additive genetic Angus-Brahman differences, heterosis effects, and least squares means for six carcass and six meat palatability traits were estimated using data from 1367 steers from the Angus-Brahman multibreed herd of the University of Florida collected from 1989 to 2009. Brahman carcasses had higher dressing percent (P<0.0001), lower marbling (P<0.0001), smaller ribeye area (P<0.0001), and ...
Introduction While there are many types of crossbreeding systems possible, the ones most likely to be useful and practical for use in Florida are some form of a rotational crossbreeding system or, in small herds and a few specialized systems, a terminal crossbreeding program. A third option, the rota-terminal, combines both systems and could also be considered for more intensively managed opera...
We investigated the effects of calpainsystem genetic markers on consumer beef quality ratings, including interactions of marker effects with hormonal growth promotant (HGP) use and tenderstretch hanging. Brahman cattle in New South Wales (NSW; n = 164) and Western Australia (WA; n = 141) were selected at weaning from commercial and research herds to achieve balance and divergence in calpastatin...
