Characterisation 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...
متن کاملBlood metabolic profiles in Uruguayan Holstein and Uruguayan Holstein x New Zealand Holstein-Friesian dairy cows
Blood metabolic profiles were determined from 40 days prepartum to 60 days postpartum in Uruguayan Holstein (UH) (n = 13) and UH x New Zealand Holstein-Friesian first cross (UH-NZHF) (n = 13) cows with seven in each group experiencing their second lactation (L2) and six experiencing their third lactation (L3). Non-esterified fatty acids increased around calving and tended to be greater in UH-L3...
متن کاملIntake 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 کاملEstimation of plasma volume in Holstein and Jersey calves.
The concentration of immunoglobulin (Ig) G in the blood of neonatal calves shortly after birth is a widely used criterion to determine the degree of acquisition of passive immunity. Another method used to determine the biological mechanisms of IgG absorption is calculation of the apparent efficiency of IgG absorption. Estimation of the efficiency of IgG absorption requires the estimation of pla...
متن کاملTaqI Polymorphism in MYF5 Gene and its Association with Body Weight in Friesian Bull Calves
Objective: The effect of MYF5 gene polymorphism on body weight was investigated in 100 Friesian bull calves. Methodology: Blood samples were collected from each animal for DNA extraction. The PCR-TaqI digestion of 1190 bp of a fragment of MYF5 gene revealed that, two fragments (983 and 207 bp) for genotype BB, three fragments (1190, 983 and 207 bp) for genotype AB and undigested fragment (1190 ...
