Mastitis-free GM cows under test in China

An article The Dairy Site reports on the progress being made by Chinese scientists seeking to bring mastitis-free genetically modified cows to market. Sun Qixin, President of the Northwest Agriculture and Forestry University tells The Dairy Site that tests on the milk from their herd of 100 GM cows have so far shown it to be safe for human consumption. However, a further 3 years of...

New genetic history of cattle could lead to better breeding methods

Geneticist and anthropologists previously suspected that ancient Africans domesticated cattle native to the African continent nearly 10,000 years ago. Now, a team of University of Missouri researchers has completed the genetic history of 134 cattle breeds from around the world. In the process of completing this history, they found that ancient domesticated African cattle originated in the...

Genetic clues to TB-resistant cattle

Scientists have identified genetic traits in cattle that might allow farmers to breed livestock with increased resistance to bovine tuberculosis (TB). The study, which compared the genetic code of TB-infected animals with that of disease-free cattle, could help to impact on a disease that leads to major economic losses worldwide. Gene clues The research, led by the University...

New EBLEX manual on "Choosing bulls to breed for better returns"

EBLEX (the English Beef and Lamb Executive) has published a manual on " Choosing bulls  to breed for b etter returns " to help guide breeders to the best choice for their herd, whether using a bull or AI. The manual explains Estimated Breeding Values (EBVs) for traits such as  ease of  calving, carcase quality, herd fertility etc. The manual can be...

Genome-wide association study reveals four variants that influence conception rates in cows

Decreasing fertility is an area of concern to the dairy industry. A team of Japanese researchers have recently published the results of a genome-wide association study of Holstein cattle which has uncovered four variants, located at  PKP2, CTTNBP2NL, SETD6 , and  CACNB2 , that modulate conception rates. The scientists believe that PKP2  and  CTTNBP2NL ...
