Intake and annual performance of Limousin × Holstein-Friesian and Simmental × Holstein-Friesian beef suckler cows, and pre-weaning growth of their calves
Intake and annual performance of Limousin × Holstein-Friesian and Simmental × Holstein-Friesian beef suckler cows, and pre-weaning growth of their calves Beef cross dairy heifers remain a significant source of replacement breeding stock for the suckler herd in Ireland. Previous studies at this centre have compared Hereford × Friesian beef suckler dams with Charolais × Friesian and Limousin × Fr...
متن کاملCharacterisation of the Whole Blood mRNA Transcriptome in Holstein-Friesian and Jersey Calves in Response to Gradual Weaning
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...
