Weaning of dairy calves is an early life husbandry management practice which involves the changeover from a liquid to a solid feed based diet. The objectives of the study were to use RNA-seq technology to examine the effect of (i) breed and (ii) gradual weaning, on the whole blood mRNA transcriptome of artificially reared Holstein-Friesian and Jersey calves. The calves were gradually weaned ove...

Commercial cow-calf producers commonly use the term “percent calf crop,” but what does it mean? Does percent calf crop represent the number of calves born relative to the number of cows bred, or perhaps it is the number of calves born relative to the number of cows exposed to a bull? Some might calculate percent calf crop as the number of calves weaned compared to the number of calves born, or ...

Feeding dairy beef, predominantly Holstein steers, has evolved into a highly specialized segment of the US beef industry. Producing acceptable-quality carcasses from dairy steers requires feeding high-energy diets and marketing them at a young age, 12 to 14 months, and weighing 1150 to 1300 lbs. Several aspects of the dairy beef program are unique compared with beef cattle. The calves are not r...
