1. Protein: Protein is the most important nutrient in chicken diet. In order to further advance the sexual development of high-quality broilers, the crown is red, preserve its meat quality and taste, improve the feather luster, and make it timely, and feed the protein level in the early stage ( 0~4 weeks) 20%~22%, late stage (after 4 weeks) 18.5%~19.5%, and appropriate addition of sulfur-containing amino acids, such as methionine. The methionine in the diet was 0.45%~0.47% in the early stage and 0.4%~0.42% in the later stage in Poultry Equipment for Sale.

2. Sulfur: Sulfur in poultry usually exists in the form of sulfur-containing amino acids. The feathers and claws of high-quality broilers contain a lot of sulfur. When chickens are deficient in sulfur, they are prone to beech. Chickens are panicked, hiding in the corners to prevent bedding, or seeing many parts of the chicken body without long hair. At the same time, copper sulfate and iron sulfate should be added, because cystine is partially sulfated due to insufficient sulfate in the body, which makes the extremely difficult methionine more scarce. This is because methionine and cystine have in vivo. Collaboration and functionality.

3, vitamins: Because high-quality broilers can not store large amounts of vitamin B2 in the body, on the other hand, the addition of anti-coccidial drugs and other antibacterial drugs in the feed can cause the absorption of vitamin B2 to be blocked, causing the toe claws to curl inward and growth retardation. Therefore, it is necessary to add vitamin B2 as appropriate. In addition, vitamin B2 can promote the growth and development of high quality broilers, maintain skin health, and promote feather and skin coloration for chicken cages prices in South Africa.
