Analysis of some components of hydrolyzed feather meal

1. Crude protein hydrolyzed feather meal contains 80%-85% crude protein, which is higher than fish meal, but the content of glycine and serine in amino acids is high, reaching 6.3% and 9.3% respectively; the content of valine, leucine and isoleucine The content is about 7.23%, 6.78%, 4.21%, respectively, which is higher than other animal proteins. Hydrolyzed feather meal has a high cystine content. Although it is destroyed during hydrolysis, it still contains 2.93%, ranking first among all natural feeds. The disadvantage is that the content of lysine and methionine is insufficient, which are equivalent to about 25% and 35% of fish meal respectively. Since cystine can replace 50% methionine in metabolism, adding an appropriate amount of hydrolyzed feather powder to the formula can supplement the lack of methionine. At the same time, hydrolyzed feather powder also has the function of balancing other amino acids. This resource should be fully and rationally utilized.

2. Effective energy value The crude fat content of hydrolyzed feather meal should be below 45%, the digestibility should be above 75%, and the chicken metabolizable energy value can reach 10.04MJ/kg.

3. Vitamins Except for the high content of vitamin B12 in hydrolyzed feather meal, the content of other vitamins is very low.

4. Minerals The sulfur content (up to 1.5%) is the highest among all feeds, but the calcium and phosphorus content is less, 0.4% and 0.7% respectively. In addition, feather meal also contains potassium, chlorine and various trace elements. The selenium content is relatively high, about 0.84mg/kg, second only to fish meal (2.0mg/kg) and some rapeseed meal (1.0mg/kg). ), much higher than other feeds.

Note: 1. Hydrolyzed feather meal belongs to animal-derived feed. According to the animal-derived feed product safety and sanitation management measures, administrative licenses must be obtained before production and operation can be carried out. The production enterprise must obtain the animal-derived feed product production enterprise safety and health certificate
