摘要
将300只1日龄雄性朗德鹅饲养至98日龄,从中选出体重相近的健康鹅150只,随机分成5组。预饲7 d后,各组日粮中依次添加0、40、80、160、320 mg/kg茶多酚,经过21 d的超饲养后统一屠宰,测定产肝性能、肥肝抗氧化性能和血液生化指标。结果表明:(1)160 mg/kg添加组肥肝重、肝脏与屠体比、肝脏与活重比最大。(2)80、160 mg/kg两添加组SOD活性最高;40、80 mg/kg两添加组GSH-Px活性最高;对照组MDA含量最高。试验表明:玉米型日粮中添加160 mg/kg茶多酚朗德鹅产肝性能和肥肝抗氧化功能最佳。
300 male Landes geese hatched on the same day were housed collectively, bred under the same conditions of light and temperature to 98 d age, then 150 healthy geese with similar body weight were selected and randomly divided into 5 treatments. After seven - days＇ pre- overfeeding, tea polyphenols（TP）was supplied in basal diets with dosage of 0, 40, 80, 160, 320 mg/kg, respectively. After overfeeding for 21 d the geese were slaughtered and their fatty liver performance, antioxidant ability and senma parameters were determined. Results are as follows： （1）The highest liver weight, the highest ratio of liver weight to carcass, and the highest ratio of liver weight to body weigh are given from group 160 mg/kg. （2）The highest SOD activity is from groups 80 mg/kg and 160 mg/kg; the highest GSH - Px activity is from groups 40 mg/kg and 80 mg/kg; and the highest MDA content is from the control group. It is proved that the supplementation to corn based diets with tea polyphenols of dosage 160 mg/kg gives the best results in the fatty liver performance and antioxidant ability.
