| 摘 要： | 选1日龄艾维茵肉鸡120只,随机分为2个处理,每个处理6个重复,每个重复10只鸡,研究低温(LAT)和日粮中添加三碘甲状原氨酸(T3,1.5 mg/kg)诱导肉鸡腹水症(AS)时对肉鸡生产性能、能量及营养物质利用率的影响。结果表明:诱导肉鸡AS发病率和死亡率分别高达66.7%和23.3%;能显著降低肉鸡的生产性能(P<0.05),提高心脏指数(P<0.05);第2周时试验组肉鸡对能量和粗脂肪的利用率极显著低于对照组(P<0.01),粗蛋白显著低于对照组(P<0.05),多数氨基酸也极显著低于对照组,精氨酸却高于对照组;第3周时除蛋白外,其他的营养物质和能量都不同程度地低于对照组,而精氨酸差异不显著(P>0.05)。当肉鸡AS发病率高时,降低肉鸡的生产性能,使肉鸡对饲料能量及粗蛋白、粗脂肪、氨基酸(除Arg外)的利用率降低。

| Abstract: | An experiment was conducted to investigate the effect of ascites syndrome in broilers(AS) on the availability of the energy and nutrient.120 Avian chickens of 1 day old were randomly divided into 2 groups(control group and test group).There were 6 replicates with 10 broilers each.In test group,AS was induced with 3,3',5-triiodothyronine(T_3,1.5?mg/kg) and low ambient temperature(LAT).The results show that: T_3 and LAT can successfully induce AS in broilers,leading to 66.7% incidence and 23.3% mortality.AS significantly decreases performance(P<0.05) and increases heart index of broilers(P<0.05).During the 2~(nd) week,the availability of the energy and the ether extract are obviously significantly lower(P<0.01) and crude protein significantly lower(P<0.05),most amino acid is also obviously significantly lower except arginine in test group than in control group.During the 3~(rd) week,the availability of the nutrient and the energy is lower than in control group than in control group while protein keeps the same(P<0.05) in test group.The results indicate that the high AS incidence rate makes the availability of the energy and nutrient decline and growth tardiness in broilers. |
