Influence 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...
متن کاملEvaluation of the Brix refractometer to estimate immunoglobulin G concentration in bovine colostrum.
Refractometry using a Brix refractometer has been proposed as a means to estimate IgG concentration in bovine maternal colostrum (MC). The refractometer has advantages over other methods of estimating IgG concentration in that the Brix refractometer is inexpensive, readily available, less fragile, and less sensitive to variation in colostral temperature, season of the year and other factors. Sa...

15 صفحه اولImmunoglobulin derived from bovine plasma as a replacement for colostrum in newborn lambs.
Newborn lambs (n = 45) at the Agricultural Research Institute of Northern Ireland were fed either 50 grams of commercial lamb milk replacer or 50 grams of commercial colostrum replacer (bovine origin) in 200 ml of water four times during the first 24 hours of life or were given ad libitum access to the ewe. Total plasma protein at 24 hours of age was highest in lambs allowed to suckle the ewe (...
