We investigated the relationship between heat-tolerant phenotypes and the genomic estimated breeding values (GEBVs) for Australian economic, productive, and heat tolerance selection indices in a Holstein Friesian lactating dairy cow herd. The study found positive associations between heat-toleran...

Heritabilities for average mature weight were 0.47 for Herefords and 0.73 for Wokalups compared to values of 0.29 and 0.54, respectively, for mature weights treated as repeated records. Rate of maturing was moderately heritable in both breeds, heritability estimates being 0.32 and 0.33. Genetic ...
plus Lake Nash in the Northern Territory. The business delivers premium beef to Australian and international markets, and has shifted its focus in more recent years to breeding purebred Wagyu cattle. The group is said to have at least

region include SNP within this region of the bovine growth hormone receptor gene, which has a marked effect on beef production traits [34], and the association of a SNP within the 5′UTR of the bovine lactoferrin (LF) gene with reproductive parameters and uterine infection in dairy cattle [...
A similar (though lesser) degree of sensitivity has been shown when comparing methods for handling the co-production of milk and meat in dairy systems (Cederberg and Stadig 2003; Casey and Holden 2005; Flysjö et al. 2011). These studies showed that system expansion resulted in considerably ...
To enable selection for improved heat tolerance, the aim of this study was to develop genomic estimated breeding values (GEBV) for heat tolerance in dairy cattle. Heat tolerance was defined as the rate of decline in production under heat stress. We combined herd test-day recording data from ...

The correlations between the breeding values from two consecutive runs were high ranging from 0.97 to 0.99. The MT RR TD model was able to make effective use of available information on young bulls and cows, and could offer an opportunity to breeders to utilize estimated breeding values for ...
