Function
1. L Tryptophan is an important nutrient.
2. L Tryptophan takes part in the renewal of animal blood plasma protein in the body
3. L Tryptophan helps nicotinic acid and the synthesis of hemoglobin. It can significantly increase antibody in pregnant animals baby.
4. L Tryptophan can promote lactation of cows and sows.
5. When animals are lack of Tryptophan,they stop growing,lose weight and reduce fat accumulation. The male breeding stock will testicular atrophy.
6. L Tryptophan is used as control agent of pellagra
Application
This product is an important nutrient. It can participate in the renewal of plasma proteins in animals and can promote the action of riboflavin. It also contributes to the synthesis of niacin and heme. It can significantly increase antibodies in pregnant fetuses and promote lactation in lactating dairy cows and sows. effect. When livestock and poultry lack tryptophan, growth stagnates, body weight decreases, and fat accumulation decreases, and the genital testes shrink.
It is used as a control agent for ecdysis in medicine.
