CRISPR/CAS9 mediated gene editing for the improvement of beef and dairy cattle
With the growing demands on agricultural production around the world, it is becoming increasingly important to figure out how to feed the growing population. For thousands of years we have been optimizing our agricultural outputs in livestock species through reproductive selection based on …

Influence of feed efficiency ranking and maternal nutrition on gut microbiome, metabolome, and transcriptome in beef and dairy cattle
… efficiency independent of the level of growth and production performance. The RFI has become a commonly used measure for feed efficiency in beef and dairy cattle. The first experiment was to determine differences in major ruminal bacteria and ruminal epithelium gene expression between …

A Prevalence Study of Southeast Origin Sale Barn Beef Cattle, Comingled in Warren County, Kentucky, Persistently Infected with Bovine Viral Diarrhea Virus, including the Effects of Season and Body Weight
… (BVD) is an economically important disease of cattle. Calves persistently infected (PI) with the bovine viral diarrhea virus (BVDV) are a powerful agent for spread of the virus. A total of 24,423 southeast origin beef cattle comingled at three Warren County, Kentucky locations were tested from …

Effect of exogenous enzymes on ruminal fermentation, pelletability and palatability of blueberry products in equine feed, and the effects of quantity of protein and starch on equine cecal environment
… is an important consideration for producers of beef and dairy cattle. One method for enhancing fermentation of fiber is application of exogenous fibrolytic enzymes (EFE) to feed. To determine whether method used to apply EFE impacts fermentation parameters by bovine ruminal microorganisms, 3 …
