Estimation 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 کاملEffects of Feeding Colostrum and Milk of Holstein Cows on Growth Rate, Immunoglobulin Levels and Metabolic Traits in Jersey Calves Produced by Embryo Transfer: Comparison with Holstein Calves
The aim of the present study was to assess the effects of Holstein dam’s colostrum and milk on growth rate, immunoglobulin levels, and metabolic traits in Jersey calves produced by embryo transfer: comparison with Holstein calves. All calves received colostrum within half an hour after birth at the rate of 2.4-3.9 L were 10% BW basis, and continued for the first 3 days and milk from after that ...
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...
متن کاملCASE STUDY: Performance of Lactating Jersey and Jersey- Holstein Crossbred Versus Holstein Cows in a Wisconsin Confinement Dairy Herd
The objective of this trial was to measure performance of paired pens of lactating Jersey and Jersey-Holstein crossbred (JX) vs. Holstein (H) cows over a year in a Wisconsin confinement dairy herd. Average daily milk yield of JX was 5.5 kg/ cow less than H, whereas average milk fat and true protein percentages were 0.61 (4.26 vs. 3.65%) and 0.19 (3.05 vs. 2.86%) percentage units, respectively, ...
