Effects of Tryptophan on Livestock and Poultry

Tryptophan is an important nutrient. It can participate in the renewal of plasma proteins in animals, and can promote the function of riboflavin, and also help the synthesis of niacin and heme, which can significantly increase the antibodies in the fetus of pregnant animals. Stagnation, weight loss, decreased fat accumulation, atrophy of testes in breeding males. Tryptophan can increase the content of animal globulin, thereby enhancing disease resistance; it can also be used with lysine, methionine, and threonine to strengthen amino acids. Adding 0.02% tryptophan and 0.1% lysine to corn products can significantly increase protein titer.

For poultry tryptophan can reduce the nitrogen emission of poultry manure, improve the utilization rate of crude protein, and reduce the environmental pollution caused by intensive livestock and poultry farming. Adding tryptophan can reduce aggression and reduce feather pecking.

For pigs, from related research, adding a certain amount of tryptophan to the diet can increase the pig’s feed intake, promote its growth, reduce stress, improve its immunity and improve meat quality. Similarly, pig tail biting due to weaning and close feeding can also be solved by tryptophan supplementation.

For dairy cows, it promotes lactation in lactating dairy cows.

In general, only a small amount of tryptophan in the feed can produce great results. The effect of tryptophan on the nutritional metabolism of pigs and poultry is mainly achieved through the following aspects: Tryptophan can be converted into nicotinamide to promote the growth of livestock and poultry and prevent the occurrence of nicotinamide deficiency; Tryptophan has an effect on fat metabolism, which can reduce Poultry liver fat content; Tryptophan can improve the protein synthesis rate of growing pig liver, skin, and overall components; Tryptophan plays a role in feed intake, production performance and feed conversion of livestock and poultry; Tryptophan also Have an impact on livestock and poultry behavior, reduce aggressive behavior, and reduce stress response.
