Product: L-Isoleucine 98.5% feed grade
Uses:
1. Adding 0.84% isoleucine can maximize the weight gain of 0-3 week old broilers, and adding 0.82% isoleucine can maximize the feed conversion rate.
2. The leucine, isoleucine and valine requirements of the three-week-old broiler chickens with the highest weight gain and feed conversion rate were 1.61%, 0.80% and 0.90%, respectively.
3. Improve the laying rate of laying hens: The daily requirement for isoleucine at the peak of laying hens (26~36 weeks old) is 9.48mg/g egg 44.47mg/kg body weight, late egg production (46~ 56 weeks old) daily requirement is 12.11mg/g egg
For 6.86 mg/kg body weight, the hens with a medium body weight of 50 g eggs have an isoleucine requirement of 760-890 mg/d.
