Abstract

This experiment was conducted to study the effects of ryegrass pellet diet on growth performance, slaughter performance and serum biochemical indexes of Yangzhou geese. A total of 300 one-day-old Yangzhou geese were randomly divided into 5 groups with 3 replicates per group and 20 geese per replicate. Geese in the groups were fed the diets supplemented with 0 (control group), 2% (group Ⅰ), 4% (group Ⅱ), 6% (group Ⅲ) and 8% (group Ⅳ) ryegrass, respectively. The experiment lasted for 21 days. The results showed as follow: 1) at 7 days of age, the average daily feed intake (ADFI) in groups Ⅱ and Ⅳ was significantly lower than that in control group (P<0.05), the average daily gain in group Ⅰ was significantly higher than that in control group (P<0.05); at 14 days of age, the ADFI in group Ⅱ was significantly lower than that in control group (P<0.05), the ratio of feed to gain in groups Ⅱ and Ⅲ was significantly lower than that in control group (P<0.05); at 21 days of age, the ADFI in group Ⅳ was significantly higher than that in control group (P<0.05). 2) The carcass weight, semi-eviscerated weight, eviscerated weight and leg muscle weight in groups Ⅰ, Ⅱ, Ⅲ and Ⅳ were higher than those in control group (P>0.05), there was no significant difference on stomachic pH among all groups (P>0.05). 3) There was no significant difference on the activities of glutamic oxalocetie transaminase and alkaline phosphatase in serum among all groups (P>0.05); the serum total protein content in groups Ⅰ, Ⅲ and Ⅳ was significantly higher than that in control group (P<0.05); the serum glucose content in groups Ⅰ and Ⅱ was significantly lower than that in control group (P<0.05); the serum glutamic-pyruvic transaminase activity in groups Ⅰ, Ⅱ and Ⅳ was significantly lower than that in control group (P<0.05). In conclusion, ryegrass pellet diet can improve the growth performance, slaughter performance and serum biochemical indexes of Yangzhou geese, and the optimal supplemental level of ryegrass is 6%.
