Abstract
This study was conducted to investigate the effects of feeding modes and low nutrient levels on growth performance and serum biochemical indexes of meat geese aged from 5 to 8 weeks. Two-factor experi-mental design was used with different feeding modes ( net bed rearing and ground level rearing) and different energy and crude protein levels (group A: 9.50 MJ/kg, 13.00%; group B: 10.00 MJ/kg, 14.00%; group C:10.50 MJ/kg, 15.00%). A total of 360 geese with an initial body weight of (1 226.89±13.23) g were randomly distributed into 6 groups with 3 replicates per group and 10 geese per replicate. The experiment lasted for 28 days. The results showed that the average daily feed intake ( ADFI) and feed to gain ratio ( F/G) of geese were not significantly affected by feeding mode ( P>0.05) , while the average daily gain ( ADG) of net bed rearing was significantly higher than that of ground level rearing ( P<0.05) . It was also demonstrated that the growth performance of geese was not significantly affected by the low nutrient level and the interaction of the two factors, although ADG and F/G of group B displayed better value. The serum uric acid ( UA) content of net bed rearing was significantly lower than that of ground level rearing ( P<0.05) , and serum triglycerides ( TG) content of net bed rearing was significantly higher than that of ground level rearing ( P<0.01) . The ser-um UA content of group B was significantly higher than that of group C ( P<0.05) . The interaction of the two factors displayed significant effect on serum glucose (GLU) content (P<0.05). It is concluded that net bed rearing can be more conducive to the growth of geese, and the optimal energy and crude protein levels for 5 to 8 weeks geese is 9.50 to 10.00 MJ/kg and 13.00% to 14.00%, respectively.关键词
