Cross-sectional analyses of a national database to determine if superior genetic merit translates to superior dairy cow performance

Liver fatty acid metabolism associations with reproductive performance of dairy cattle

The response to genetic merit for milk production in dairy cows differs by cow body weight

“…Information is generally lacking on the association between cow BW (stratified within herd) and longevity, especially in grazing production systems where feed is generally limited. The implications of the results from the present study are that expected phenotypic differences among animals (i.e., dams or sires) based on their respective estimates of genetic merit (Ring et al, 2021) would need to be rescaled based on the BW of the cow. The extent of rescaling would be a function of the BW of the cow herself.…”

Sensory Consumer and Descriptive Analysis of Steaks from Beef Animals Selected from Tough and Tender Animal Genotypes: Genetic Meat Quality Traits Can Be Detected by Consumers

“…Previous studies have compared the phenotypic performance of cattle differing in genetic merit [31][32][33][34]; the hypothesis of the present study was that a detectable difference in meat tenderness should indeed exist between the two genotypes of cattle divergent in the genetic merit for tenderness. In fact, the observed mean difference in the tenderness score between both genotypes, when assessed by the trained panels (0.22 to 0.37), was larger than the expectation of 0.13 based on the difference in EBV of the heifers themselves (i.e., average of the EBV of the sire and dam).…”

“…Several breeding goals exist in the dairy [37], beef [31,38] and beef-on-dairy industries [39]. These breeding goals are comprised of many traits thought to influence profit, thus providing a proven [32,38,40] vehicle to achieving genetic gain in a number of traits simultaneously, even if antagonistically correlated. Inclusion of meat sensory traits in such breeding goals is crucial to achieve generation-on-generation gains in these metrics.…”
