WitrynaThe trait with the largest genetic variation was IgM. Colostral BRIX differed across parities and herds (P < 0.001), while it was similar across calving seasons (P = 0.247) and years (P = 0.400). The BRIX estimates of older cows (parities 3, 4, and ≥ 5) were larger than those of younger cows (parities 1 and 2; Fig. 1). WitrynaThe main topic of my research career has consisted in the study of the genetic influence in complex traits from a wet- and dry-lab double perspective.

WitrynaOne of potential causes for such different values of heritability coefficients are rearing conditions, housing and nutrition of cows on farms, i.e. applied management, through the effect on total variation of expressed traits. Different values of heritability of milk traits for Friesian cows in Egypt and Germany were investigated by TAWFIK at ... WitrynaBergmann (2003) reported variation from 0.08 to 0.83 for direct heritability for yearling weight in studies with various breeds of beef cattle, and the author further stated that due to the great use of the trait as a selection criterion, several authors have been concerned with obtaining more accurate estimates of the genetic parameters.

WitrynaBreeding for these traits makes it possible to produce cows with an inherently higher chance of experiencing better health and welfare or that can better fight off infection. Health traits may have a lower heritability than some other traits, but including them in your breeding decisions will have a positive cumulative effect on your herd. WitrynaDairy genetics help predict how characteristics such as milk production, increased solids or health and management traits are passed onto the next generation of cows. The effect of breeding decisions is cumulative, meaning they build over the generations and have a key role to play in farm profitability. We invest over £500,000 each year in ...
