The effects of zinc sulphate administration to pregnant sheep on some biochemical parameters in blood sera of sheep and its lambs, and birth weights of lambs

The aims of this study were to demonstrate the effects of zinc sulphate adm inistration (2 g/week PO, 2% solution) on zinc, copper, iron, calcium and m agnesium levels in blood serum of 20 pregnant Ivesi sheep during the last 2 month of pregnancy, immediately post partum as well as in their newborn la mbs. In these 20 lambs, also total serum protein, gamma globulin and birth weight were determined. The control group consisted of 15 pregnant sheep an d their 15 Iambs housed under the same conditions. Zinc sulphate administer ed to sheep caused significant increases in their serum levels of zinc as w ell as in those of their lambs. The lambs of the zinc supplemented group ha d also slightly higher birth weights (not significant) and significant high er gamma globulin levels, whereas the total protein values was almost ident ical in both groups.
