Genetic testing for the Y-chromosome can be performed within days of birth and can aid in the early identification of a sterile female bovine. Physical examination of the calf may also reveal differences: a subjective assessment is that frequently there is a lengthened tuft of hair at the ventral tip of the vulva in a freemartin heifer atypical ...
The field-based progeny testing is highly required when the selected bulls are to be distributed in a large area to many farmers in different environments. Conducting a field-based progeny testing, especially in smallholder production systems of Asia and Africa, require huge resources both financial and infrastructural - a large AI network ...
Animal breeding is a branch of animal science that addresses the evaluation (using best linear unbiased prediction and other methods) of the genetic value (estimated breeding value, EBV) of livestock. Selecting for breeding animals with superior EBV in growth rate, egg, meat, milk, or wool production, or with other desirable traits has ...
The Department of Health and Human Services will put in an additional $101 million to ramp up monitoring of people who have been exposed to sick animals, contact tracing and genetic testing of the ...

The Food and Agriculture Organization of the United Nations (FAO) has taken initiative and published two global assessments of livestock biodiversity: The State of the World's Animal Genetic Resources for Food and Agriculture (2007) and The Second Report on the State of the World's Animal Genetic Resources for Food and Agriculture (2015).
Polled genetics, long a staple in beef cattle breeding are becoming more popular among dairy farmers, with more polled calves being born to dairy cattle every year. Genetic testing can now determine if cattle carry genes for growing horns.
