Increased colostral somatic cell counts reduce pre-weaning calf immunity, health and growth.
Our objective was to study the relationships between colostral somatic cell counts (SCC, a criterion for mastitis severity at parturition) and early calf growth, blood indicators of immunity, and pre-weaning faecal and health states. Sixty-nine Holstein cows were assigned to three groups of greater (n = 21, 5051 × 10(3)), medium (n = 38, 2138 × 10(3)) and lower (n = 10, 960 × 10(3)) colostral S...
متن کاملBlood Cell Growth Factors
SUMMARY Growth factors or colony stimulating factors (CSFs)recently became the subject of headlines around the world. Many published articles in the last few years indicate that the CSFs can correct anemia and pancytopenia of the great majority of patients. Recombinant CSFs are available to the many scientific and therapeutic centers in the U.S.A, Europe and Japan these days. Erythrop oieti...
متن کاملInterferon synthesis by human colostral leucocytes.
The antiviral potential of human colostral leucocytes was assessed by their capacity to produce interferon. Leucocytes cultured from colostrum were stimulated by mitogens or Newcastle disease virus (NDV) to produce interferon which, by metabolic and physicochemical criteria, corresponded to normal human leucocyte interferon. Prepartum cells produced higher levels than postpartum cells. Colostra...
متن کاملGrowth and Growth Factors
SOCS2 inactivation, which leads to growth hormone hypersensitivity and overgrowth, is selected as the mechanism of the year in this chapter. The second paper shows that PPAR plays a role in the growth of male mice. Under new paradigms, we learn that the disruption of a paternally expressed gene from the Gnas locus, XL s, is associated with poor postnatal growth, and we also discover a new molec...
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...
