Effects of Chitosan on Growth Performance, Slaughter Performance, Viscera Indices and Serum Biochemical Parameters of Geese during 14 to 70 Days of Age
摘要
Abstract
This experiment was conducted to study the effects of dietary different chitosan supplemental levels on growth performance, slaughter performance, viscera indices and serum biochemical parameters of geese during 14 to 70 days of age, and to explore the dietary optimal chitosan supplemental level for geese. Three hundred and sixty 14?day?old healthy male Yangzhou geese with similar body weight were randomly divided in?to 5 groups with 6 replicates per group and 12 geese per replicate. Geese in the control group were fed a basal diet, and the other geese in the experimental groups were fed experimental diets supplemented with 250, 500, 1000 and 2000 mg/kg chitosan, respectively. The experiment lasted for 56 days. The results showed as fol?lows: compared with the control group, 1 ) dietary supplemented with 500 mg/kg chitosan significantly in?creased the body weight of geese at 42, 56 and 70 days of age, average daily feed intake and average daily gain at 14 to 70 days of age ( P<0.05) , but significantly decreased the ratio of feed to gain of geese at 14 to 70 days of age ( P<0.05) . 2) Dietary supplemented with 250, 500, 1000 and 2000 mg/kg chitosan signifi?cantly decreased the percentage of abdominal fat of geese ( P<0. 05 ) . 3 ) Dietary supplemented with 500 mg/kg chitosan significantly increased the heart index, liver index, spleen index, jejunum index, ileum index, cecum index of geese (P<0.05). 4) Dietary supplemented with 500 mg/kg chitosan significantly in?creased serum globulin and glucose contents of geese ( P<0.05) , significantly decreased serum alkaline phos?phatase activity (P<0.05). Dietary supplemented with 250, 500 and 1000 mg/kg chitosan significantly de?creased serum triglycerides and total cholesterol contents ( P<0.05) . It is concluded that diet supplemented with chitosan can improve the growth performance of geese. They also have a certain influence on slaughter per?formance, viscera indices and serum biochemical parameters. Thus the effect of dietary supplemented with 500 mg/kg chitosan is better in the production practice of geese.关键词
