Effects of natural zeolite clinoptilolite on passive immunity and diarrhea in newborn Holstein calves
In the present study, the effects of natural zeolite clinoptilolite on absorption of immunoglobulins from colostrum and incidence of enteric diseases were evaluated. In a completely randomised design, thirty Holstein calves were fed pooled colostrum and then milk containing zero (control), 0.5 (T1), 1.0 (T2), 1.5 (T3) and 2.0 (T4) g clinoptilolite per kg body weight per day through day 45. Bloo...
متن کاملEffect of Saccharomyces Cerevisiae Yeast Metabolites on Colostrum Quality and Passive Immunity Transfer in Calves
Basic nutrients, minerals, total protein and its fractions in colostrum from cows fed feed supplemented with yeast metabolites (60 g/d/animal) in perinatal period, as well as the level of immunoglobulins in calves’ blood serum on the 2 and 35 d of their life were determined. Additionally, the total immunoglobulin index in calves aged 3-4 weeks was calculated. It was demonstrated that feed with ...

since the 1960s the age effects on learning both first and second language have been explored by many linguists and applied linguists (e.g lennerberg, 1967; schachter, 1996; long, 1990) and the existence of critical period for language acquisition was found to be a common ground of all these studies. in spite of some common findings, some issues about the impacts of age on acquiring a second or...
15 صفحه اولFormulation of colostrum supplements, colostrum replacers and acquisition of passive immunity in neonatal calves.
Provision of an adequate mass of IgG from maternal colostrum is essential to health and survival of neonatal calves. Colostrum supplements (CS) have been developed to provide supplemental immunoglobulin when maternal colostrum is of poor quality. However, colostrum replacers (CR) that provide > or = 100 g of IgG have not been formulated. Our objective was to determine the absorption of IgG in n...
