| Abstract |
Physiological and productive responses to recombinant bovine somatotropin (rbST) injection and calcium soap of fatty acids (CSFA) supplementation were studied in post-weaning male Rahmani lambs. Male lambs (n=20) of similar initial body weight (27.9kg) and age (162d) were divided randomly into four equal groups. The first was fed the basal diet and served as control; the second GH) was injected with 100mg of rbST biweekly; the third (CSFA) was supplemented with 50g/d of calcium soap of fatty acids and the fourth (GH+CSFA) was injected with 100mg of rbST biweekly plus 50g/d of CSFA. Treatments increased (p<0.05) average daily gain and final body weight. Concentration of insulin-like growth factor-l (IGF-l) in lambs treated with (GH) and (GH+CSFA) was higher (p<0.01) than that of CSF A and control groups. Hematological parameters (RBC, WBC, and hemoglobin concentrations) did not change. Animals injected with rbST had higher (p<0.05) serum total protein than other treated groups and controls. Control lambs showed the least serum albumin concentration. Injection of rbST and supplementation of CSFA increased serum glucose in treated lambs compared to controls. Serum urea concentration was not affected by injection of GH, while CSF A supplementation decreased (p<0.05) serum urea concentration compared to the control group. Serum triglycerides concentration decreased (p<0.0l) in rbST injected lambs than other treatment groups. Lambs supplemented with CSFA only or in combination with rbST injection had higher (p<0.05) concentration of serum cholesterol than control or rbST-injected lambs. The results of the present study suggest that rbST and CSF A may increase the average daily gain and improve the physiological status of growing lambs.
Key Words: rbST. CSFA, average daily gain, IGF-l, cholesterol
