Nutritive value of feather meal
Feathers contain a large amount of keratin, which is not easily hydrolyzed by pepsin or trypsin in animals. Untreated feather powder has a lower value for feeding. The nutritional value of feather meal varies depending on the processing technology.

The crude protein content of hydrolyzed feather meal was 71%, the protein content of enzymatic feather powder was 82.6%,

and the crude protein content of expanded feather powder was 93.55%. Compared with the feather raw powder, the pepsin digestibility of the treated feather meal was significantly improved. In addition to low levels of lysine, methionine, histidine and tryptophan, feather meal is rich in other amino acids, especially cysteine,proline, arginine, isoleucine and threonine. In fish meal. Feather meal contains 0.45% to 2.02% calcium, 0.57% to 0.72% phosphorus, and 0.84mg/kg selenium. It also contains VB12 and unknown growth factors. The value in farming applications is very high.

It can improve the health level of fur animals, improve the feeding capacity, promote the improvement of fur condition, and make the coat color healthier and more lustrous. Through squeezing (expansion), feather meal has good palatability, high digestion and absorption rate, good safety, eliminates feed bacteria pollution, improves growth performance and cortex, promotes growth and development, and makes skin removal time more than 10 days earlier than usual. Increase feed return , It strengthens micronutrients and has a significant effect on preventing nutritional deficiencies such as hoof disease, self-biting and self-mutilation. It can also improve the anti-stress ability of animals and prevent the occurrence of red claw disease, dermatitis, dermatitis, skin keratosis, scab and chapped disease.
