Abstract: Experiments were designed to associate serum gammaglobulin levels with various performance parameters in young stock. Gammaglobulin levels were higher in pregnant than non-gravid ewes and does. Gammaglobulin levels fell gradually during pregnancy; at 145 days they were comparable to those in non-gravid animals. Gammaglobulin levels and weight gains were lower and mortality was higher in bottle-raised lambs. Lambs with gammaglobulin levels ? 0.5 g/100 ml of serum at 24 h of age showed lower survival percentages than those with higher concentrations. Colostrum deprivation in lambs resulted in low levels of gammaglobulin which decreased up to 72 h of life, significantly (P?0.01) different from the colostrum-fed group. A 20% mortality was observed in colostrum-deprived lambs. Measurements of serum gammaglobulin were most reliable between 24 and 48 h after birth and accurately assessed the amount of passive transfer. Such measurements could be used as a monitoring technique when large numbers of lambs/kids are reared and would help control higher rates of morbidity and mortality in a newborn population. |
