Effects of Kinggrass on Growth Performance and Blood Physiological and Biochemical Indexes of Geese

This experiment was conducted to study the effects of kinggrass on growth performance and blood physiological and biochemical indexes of geese. A total of 240 28-day-old Hainan indigenous geese with similar body weight were randomly divided into 4 groups with 3 pens of 20 geese per group and fed for 60 days. Three sets of diets were used in this trail were control diet and diet supplemented with 7.5%, 10% or 12.5% kinggrass, respectively. The results showed as follows:1) kinggrass diet significantly improved geese's body weight, daily weight gain, daily feed intake (P < 0.05) and Feed intake/gain of groupⅡ was the lowest (P < 0.05).2) kinggrass diet had no significantly effect on blood Physiological indexes.3) kinggrass diet significantly decreased the GPT, TP and TG content and improved other blood biochemical indexes. In conclusion, kinggrass will not harmful to health of geese, and supplementing 10% kinggrass on goose's diet could improve.
