不同木薯干配比饲养肉鸭试验

木薯富含淀粉但含蛋白质极少且品质非常低劣,正确掌握其在日粮中的用量直接影响到肉鸭的生长。900只鸭的生长试验表明:木薯干在樱桃谷肉鸭(15至50日龄)日粮中的配比为30%时,既能保证最大生长速度,又能大幅度替代了玉米。配比大于35%时,明显抑制肉鸭生长,导致饲料报酬下降。

Feeding Meat-Duck With Rations Containing Different Amount of Cassava

The growth rates of 900 meat-ducks,which was divided into three groups of 300 individuals and fed with three rations containing 10,30 and 40 per cent of dry cassava separately,were investigated.The growth rate and feed-reward of ducks fed with the ration containing 30 per cent of dry cas- sava were greatly similar(P>0.1)to what fed with the ration conta- ining 10 per cent of dry cassava.When the ration contained more than 35 per cent of dry cassava,duck growth was greatly hampered and the feed- reward declined enormously.
