Abstract

The purpose of this experiment was to study the effects of adding Eucommia ulmoides leaf extracts into diets on growth performance, serum biochemical, immune and antioxidant indexes of meat rabbits, and to discuss the application effect of Eucommia ulmoides leaf extract in the fattening period of meat rabbits. Eighty Hyla meat rabbits with similar birthday age, good health and no significant difference in body weight[(726.55±94.92) g] (P>0.05) were randomly divided into 4 groups with each group had 10 replicates and each replicate had 2 rabbits (half male and half female). The rabbits in control group were fed a basal diet (without any antibiotics), and those in test groups Ⅰ, Ⅱ and Ⅲ were fed the basal diet supplemented with 100, 200 and 300 mg/kg Eucommia ulmoides leaf extracts, respectively. There was a pretrial period of 5 d followed by an experimental period of 30 d. The results showed as follows:1) adding 100 to 300 mg/kg Eucommia ulmoides leaf extract into diets could increase the average daily gain and average daily feed intake of meat rabbits, but the differences between test groups and control group were not significant (P>0.05). 2) Compared the control group, adding 100 to 300 mg/kg Eucommia ulmoides leaf extracts into diets could significantly increase the serum total protein and albumin contents (P<0.05); meanwhile, adding 200 mg/kg Eucommia ulmoides leaf extracts into diets also could significantly increase the serum globulin content (P<0.05), and could increase the serum immunoglobulin A content (P<0.05), superoxide dismutase (P>0.05) and glutathione peroxidase activities (P<0.05) in different degrees. Considering all indexes of this experiment, among three Eucommia ulmoides leaf extracts adding amounts in this experiment, the effect of 200 mg/kg is the best.
