Roosters and hens should separate

According to the difference in the physiological characteristics of the male and female meat, chickens can be saved in groups and the economic benefit can be increased by 5-10%. Male and female chickens have different growth rates. The roosters grow fast. At 4, 6, and 8 weeks of age, the weights are 13%, 20%, and 27% higher than those of the hens. If the male and female polycultures have different weights, the food troughs and troughs have different requirements, and they tend to miss out on each other. The diet of hens is greatly affected. Male and female hens have different genetic properties. After 7 weeks of age, the growth rate of hens was relatively reduced, and the consumption per kilogram of weight increased sharply. At the age of 7 weeks, the hens were sold with high feed efficiency and economy. The growth rate of the rooster decreased after 9 weeks of age, so the best selling efficiency of the rooster was 9 weeks old. Male and female chickens have different environmental requirements. The early roosters require higher temperatures than hens and lower hens later. Because the cock weighs more than the hens. Therefore, the incidence of breast cysts is high, requiring loose material and appropriate thickening. The nutritional needs of male and female chickens vary. Roosters have poorer ability to deposit fat than hens, but roosters can use proteins more efficiently. The protein in the early cock feed can reach 25% and the hen can be 21-23%. The addition of lysine can significantly increase the growth rate and feed utilization rate of the rooster, while the hen response is small; feeding chlortetracycline can improve the hen's feed efficiency, while the rooster does not respond.

Chitosan Series

Chitosan is a product of n-deacetylated chitosan. Chitin, chitosan and cellulose have similar chemical structure. Cellulose is hydroxyl group at C2 position, chitin and chitosan are replaced by an acetyl group and an amino group respectively at C2 position. Chitin and chitosan have many unique properties such as biodegradability, cell affinity and biological effect, especially chitosan containing free amino group, which is the only basic polysaccharide in natural polysaccharides.

The amino groups in the chitosan molecular structure are more reactive than the acetylamino groups in the chitin molecule, which makes the polysaccharide have excellent biological functions and can carry out chemical modification reaction. Therefore, chitosan is considered as a functional biomaterial with greater application potential than cellulose.

Chitosan is the product of natural polysaccharide chitin removing part of the acetyl group, with biodegradability, biocompatibility, non-toxicity, antibacterial, anti-cancer, lipid-lowering, immune enhancement and other physiological functions. Widely used in food additives, textile, agriculture, environmental protection, beauty care, cosmetics, antibacterial agent, medical fiber, medical dressings, artificial tissue materials, drug slow release materials, gene transduction carrier, biomedical fields, medical absorbable materials, tissue engineering carrier materials, medical and drug development, and many other fields and other daily-use chemical industry.
