Abstract

This experiment was conducted to study the effects of cellulase added to peanut seedling diets on growth performance, nutrient apparent utilization and digestive enzyme activities of meat geese. A total of 120 four-week-old Zhedong white geese were randomly divided into 3 groups. Geese were fed diets with 15% (group A), 23% (group B) and 23% (group C) peanut seedling powder, respectively, and 3‰ cellulose was added in the group C. Each group consisted of 5 replicates with 8 geese per replicate, and males and females were in half. The body weight, feed intake, nutrient apparent utilization and endogenous digestive enzyme activities in the pancreas, muscular stomach and duodenum were measured. The results showed that compared with group B, adding 3‰ cellulase in peanut seedling diets (9.7% crude fiber) significantly increased the average daily gain of geese (P<0.05), but the average daily feed intake and feed to weight ratio were not significantly affected (P>0.05); significantly increased the digestibility of crude ash, crude protein, crude fiber, calcium, total phosphorus, glycine, cysteine and methionine (P<0.05 or P<0.01); significantly enhanced protease and amylase activities in pancreatic (P<0.05), protease activity in muscular stomach (P<0.05), and lipase activity in intestine (P<0.05). In conclusion, adding 3‰ cellulase to the peanut seedling diets with high crude fiber can enhance the digestive enzyme activity and improve the nutrient apparent utilization of diets. It is an effective way to exploit and utilize the peanut seedlings feed resources.
