Genomic editing technology increasingly shows potential for improving disease resistance within livestock populations, as researchers in China report success introducing resistance to the CSFV in pigs.
When raising replacement heifers, cost per pound of gain is a far more important metric than daily feed cost, according to Tamilee Nennich, dairy nutritionist and board member for the Dairy Calf and Heifer Association.
As one of the researchers who helped developed pigs resistant to the Porcine Reproductive and Respiratory Syndrome (PRRS) virus said, "At the very least, the development of PRRS-resistant pigs is a new tool for im
Pregnant heifers are one cohort on dairies that don’t need nutrient-rich diets. In fact, over-feeding mature heifers can lead to excess fat deposition, which may cause calving difficulties and challenging lactation transitions.
Genomic editing technology such as CRISPR/Cas9 offers tremendous potential for accelerating genetic progress, but a new ruling from the European Court of Justice (ECJ) appears likely to stifle research and development.
The health and productivity of young calves can be affected by a wide range of metabolic and pathogenic conditions. Among the maladies that can profoundly affect calves’ health is their intake and balance of sodium.
Researchers at UC-Davis have developed a handy, easy-to-use diagnostic tool to streamline monitoring of calves for respiratory disease, so they can be detected and cared for early in the disease process.
