摘要
试验旨在研究固体蛋氨酸与液体蛋氨酸对樱桃谷鸭生长性能的生物效价影响。试验选用樱桃谷鸭鸭苗7 257只,分两个养殖户饲养,每个养殖户两个鸭棚。试验1、2组分别饲喂添加液体蛋氨酸产品MHA-FA和固体蛋氨酸产品DLM的日粮,试验期为37 d,观察并记录体增重、饲料消耗量等指标。试验结果表明,樱桃谷鸭日粮DLM:MHA-FA为65:100(用产品重量比)替代MHA-FA,饲喂效果相同,但可降低饲料成本。
This study was conducted to study the impact of solid methionine and liquid methionine biological potency of Cherry Valley on growth performance. 7 257 Cherry Valley ducklings were selected and divided into two farmers farming, each farmer had two duck sheds. Test group 1 and 2 were fed with MHA-FA diet and add DLM di- et. Trial period for 37 days. Test observe and record the body weight gain, feed consumption and other indicators. The results showed that Cherry Valley diets with 65： 100（DLM： MHA-FA, product weight ratio） alternative MHA-FA, with the same feeding effects, it can reduce feed costs
