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 کاملPREPARATION OF ENRICHED IMMUNOGLOBULIN M AND IMMUNOGLOBULIN A FROM HUMAN PLASMA
As IgM and IgA-enriched preparations are needed to complete the immunotherapeutic spectrum, a simple procedure is described for the preparation of IgM and IgA enriched immunoglobulins. Fraction III which was prepared by cold ethanol fractionation was treated by octanoic acid followed by ethanol precipitation and ion-exchange chromatography using Sephadex DEAE A-50 and 0.1 M tris-D.35M NaCI ...
متن کاملInfluence of injectable immunoglobulin on serum immunoglobulin concentrations in dairy calves.
The influence of a purified Ig preparation on morbidity, mortality, and performance of purchased calves was evaluated. Calves (n = 187) were 3 to 8 d of age and were infused i.v. (blocks 1 and 2) or s.c. (blocks 3 and 4) with a purified Ig preparation derived from bovine blood that was obtained from an abattoir (n = 88) or were infused with 0.9% NaCl saline (n = 99). The Ig solution was purifie...
متن کاملAnticardiolipin Antibodies and Immunoglobulin M and A in Graves’ Disease
Background: Graves’ disease is an autoimmune disease, characterized by the presence of antibodies directed to TSH receptor or nearby regions as well as antibodies to double strands DNA (dsDNA) anticardiolipin and nuclear antibodies. This study evaluated anticardiolipin and rheumatoid factor, such as IgA and IgM antibodies in patients with Graves’ disease. Patients and methods: Anticardiolipin a...
متن کاملInfluence of Starch Sources in Prepartum Diet on Colostrum Quality and Blood Immunoglobulin Concentration of Calves
The main objective of this study was to evaluate the effect of dietary inclusion of wheat or corn as the main source of starch in prepartum diets on colostrum composition, colostrum IgG1 and IgG2 concentrations, serum IgG1 and IgG2 concentrations of calves and efficiency of IgG1, IgG2 and total Ig absorption. For this purpose, thirty primiparous and twenty multiparous Holstein cows were used in...
