Polyclonal anti-sera were collected from sheep and chicken immunized with adipocytes plasma membranes. Thirty two male wistar rats, weighing 185-215 grams, were divided randomly into 4 groups (trial 1: control group and treat group, trial 2: control group and treat group), with 8 rats in each group. The experiment lasted for 7 weeks. Trial one: The control group received four consecutive daily intraperitoneal injections of 1ml of sheep normal sera. The same 4 day daily dose of group sheep anti-rats sera adipocyte plasma membrane anti-sera was administered to the treat group. The results showed that the treatment for treat group increased body weight by 6.35% (p<0.05) and food intake by 6.85%, and improved food conversion efficiency (Food intake/gain) by 45.00% (p<0.05). Periernal, epididymal and omental adipose deposit weights were decreased by 23.92% (p<0.05), 34.45% (p<0.05) and 0.98% respectively, while total fat content decreased by 20.92%. Trial two: The control group received four consecutive daily intraperitoneal injections of 1 ml of chicken normal sera, the results of injections of chicken anti-rats sera adipocyte plasma membrane antis-era administered to the treat group indicated that chicken anti-rats adipocyte plasma membranes immunization had an disadvantageous effect on the growth of the wistar rats by the end of 7th wk, compared with the control group. The immunized group decreased in total weight by 40 gram (p<0.05) an averagely and in food intake noticeably (p<0.01). The deposition of fat and the rates of TG and FFA in serum had no statistical significance. |
