1. Fishmeal: Fishmeal is the most ideal animal protein feed for chickens. Its protein content is high, generally 50 to 65%. With less than 12% of crude fat and less than 20% of ash content, it is rich in calcium, phosphorus and vitamin B12. It contains particularly rich lysine, methionine and tryptophan. These characteristics are suitable for the nutritional needs of black-bone chickens. They are chicks and species. Indispensable feed for chickens. However, the amount of salt depends on the level of salt, and may generally account for 5 to 10% of the diet. In addition, fishmeal contains more fat and is susceptible to deterioration. Attention should be paid when using it. 2. Flesh powder: It is processed from the slaughter of livestock and poultry waste. Blood meal is made from animal blood, containing more than 80% of crude protein, and rich in lysine, arginine and iron, but it has smell, poor palatability, not digestible, chicks are best not to use, breeders can use about 3%. The crude protein content of MBM is between 45 and 50%. The calcium and phosphorus content is relatively high and the proportion is appropriate, but the crude fat content is relatively high and it is easily spoiled and deteriorated. 3. Silkworm cocoon powder: high fat content, should be used after degreasing treatment. It usually contains about 60% of crude protein. However, silkworm cocoons have a certain amount of stink and odor. Feeding too much will affect the taste of the product. Therefore, the feed amount should not be too high and should be limited to 2 to 3%. 4. Feather powder: It is a new type of protein resource after feathers have hydrolyzed keratin protein. The protein content is as high as 80%. However, due to the extremely limited amino acid content, the quality is poor and the grade is low. It is not appropriate to feed more. In addition, unicellular algae protein is a new source of feed protein recently, many experts and scholars are working on this research, as well as new protein feeds such as feed yeast, etc., have gradually entered the ranks of protein feed. Protein is an indispensable material for the body and constitutes the main material for tissue cells. Therefore, it is recommended that you use good quality ingredients during the growth and development of chickens. Do not overlook the growth of chickens in order to save costs. This is not worth the candle. Optics,Blank Glass,Glass Blanks For Crafts,Glass Ornament Blanks Shandong Freedom Technology Co.,Ltd , https://www.sdfreedomtech.com
Protein feed is commonly used in chickens. The raw materials for protein feeds include fish meal, feather meal, silkworm meal and blood meal. Although these are commonly used, the use of fish meal in feeds is less because of high cost.
