Some chicken farmers are accustomed to feeding raw grains such as corn, millet and sorghum to their chickens, which not only reduces feed utilization, but also causes harm to the chickens and can result in more waste of feed. No ground raw grains, both convenient and labor-saving , saving money but low feed utilization.
Since chickens do not have teeth and can swallow without chewing, they have a short intestinal tract. The food eaten by chickens stays in the intestine for a very short time, only four hours, which makes it difficult to digest and absorb completely, and the food is wasted. Since chickens are simply fed with some kind of raw food, the variety is single and the nutrient content is incomplete.
Long-term feeding will affect the growth and development of chickens. Feeding chickens with raw grain has low digestion level and incomplete nutrition, resulting in poor growth of chicks, slow growth of broilers, low egg production rate and low economic efficiency. The correct feeding method is to grind raw grains such as corn and wheat into flour and feed the chickens with other raw materials such as bran, soybean cake, fish meal, bone meal and stone meal to make pellet feed.
Chicks need higher energy and higher protein requirements to feed. In the general diet, grain (corn, broken rice, etc.) is 50-60%, bran (rice bran, wheat bran, etc.) is 5-10%; oil cake (peanut cake, soybean cake, hemp cake, etc.) 20-25%; animal feed (fish meal, meat meal, etc.) 7-20%; bone meal, shell meal 4-5%; salt 0.3-0.5%. Add feeding green feed, especially when there is no vitamin additive, can not break feeding green feed, feeding about 30-50% of the amount of concentrate feed.
Hens need specific levels of protein and minerals to lay eggs day in and day out. They do not have large reserves. In order to make eggshells, she must get calcium from her feed, deposit it in her bones, and then extract it from her bones. Egg whites are almost pure protein, so she needs a steady diet of protein to be able to excrete it as eggs.
In order to promote the normal growth of broilers, prevent diseases and improve production and economic efficiency, amino acids, vitamins, trace elements, antibiotics, antioxidants, fungicides, enzymes and colorants should be added to the pelleted feed to promote the growth and development of broilers.
The additives in the feed must be thoroughly mixed and stirred. The type and amount of additives should be based on actual needs, such as most feeds in the diet vitamin and trace element content is not complete, attention should be paid to the appropriate proportion of a variety of vitamins and trace elements to add additives, often add mold inhibitors and antioxidants in the summer rainy days.
