Colostral immunoglobulin G as a predictor for serum immunoglobulin G concentration in dairy calves
Feeding newborn calves high-quality colostrum is of well-recognised importance as calves that do not receive an adequate concentration of immunoglobulin-G (IgG) have an increased risk of morbidity and mortality. This experiment aimed to characterise IgG concentrations in colostrum from the first milking in New Zealand dairy cows, examine IgG status of calves, and to evaluate the use of a refrac...
متن کاملInfluence of parenteral administration of chamomile (Matricaria recutita L.) extract on colostral IgG absorption in neonatal calves
In this study, the effect of chamomile extract on the ability of neonatal calves to absorb immunoglobulin G (IgG) was evaluated. An ethanolic extract of chamomile was obtained with the concentration of 111 mg/ml. Calves were randomly divided into four groups, each receiving one of four chamomile treatments; 1: low dose (LC; 5.5 mg/kg body weight; 2: moderate dose (MC; 11 mg/kg); 3: high dose (H...
متن کاملVariation in colostral immunoglobulin G concentration in fat tailed sheep and evaluation of methods for estimation of colostral immunoglobulin content
In ruminants, colostrum is a vital source of immunoglobulins that provide passive immunity for their offspring during the neonatal period. It is suggested that colostral immunoglobulin G (IgG) concentration varies between and within breeds and could also be affected by maternal factors. The aim of this study was to investigate possible effects of litter type and ewe parturition number on colost...
متن کاملA Randomized Clinical Trial Evaluating Metabolism of Colostral and Plasma Derived Immunoglobulin G in Jersey Bull Calves
BACKGROUND Intravenous plasma administration has been recommended in healthy or sick calves with failure of passive immunity. HYPOTHESIS IV administered plasma-derived immunoglobulin G (IgG) undergoes increased catabolism as reflected by a rapid decrease in serum IgG concentration with an increase in fecal IgG concentrations within 48 h. ANIMALS Thirty newborn Jersey calves. Fifteen were fe...
متن کاملPharmacokinetics and dosage regimen of cefpirome in febrile cross-bred calves
The pharmacokinetics of cefpirome after a single intravenous injection of 10 mg.kg -1 was studied in febrile cross-bred calves. E. coli endotoxin was administered intravenously to induce fever in calves. Blood samples were collected at different time intervals and cefpirome levels were estimated by using microbiological assay technique. Based on the plasma drug levels, the pharmacokinetic pa...
