With the development of the chicken industry, especially the industrialized chicken industry, the problem of handling and reusing chicken manure has been increasingly valued by people. Chicken manure is not only a good organic fertilizer for crops, but also a good feed for livestock and poultry, especially in the current situation of insufficient food production in China, it is of great significance to use chicken manure as feed for development and utilization. First, the nutritional value of chicken manure as feed The chicken's digestive tract is very short, only 7 times its body length, while cattle and sheep's digestive tract is 30 times the body length. The horse is 15 times. Therefore, the feedstuffs eaten by chickens stay in the digestive tract for a relatively short period of time, and the digestion and absorption rate is very low. For example, the chicken digestibility of corn is 80%, and the digestibility of wheat bran is only 48%. Therefore, Chicken manure contains many undigested nutrients. It was determined that the caged hens contained 89.7% of dry matter, 28.0% of crude protein, 11.3% of pure protein, 14.4% of digestible protein, 12.7% of crude fiber, 28.7% of nitrogen-free extract, 8.8% of calcium, and 2.5% of phosphorus. Lysine 0.5%, histidine 0.22%, methionine 0.1%, leucine 0.86%, and phenylalanine 0.48%. This shows that chicken manure is rich in nutrients, especially crude protein. However, 47%-69% of the crude protein composition is non-protein nitrogen, which is mainly in the form of uric acid. Therefore, the crude protein in chicken manure is not as valuable as monogastric animals such as pigs and poultry, as compared to cattle and sheep. In addition, chicken manure energy is low, with an average of 2.76-5.65 megajoules of metabolic energy per kilogram of dry chicken manure. Second, the chicken manure feed effect 1. Feed cattle. About 30% of dried chicken manure was incorporated into dairy cow compound feed. After 60 days of feeding, the milk production and milk fat percentage were not affected, and milk was not odor. 35% dried chicken manure was added to beef cattle compound feed. The daily gain increased by 20.5% and the feed conversion rate increased by 8.0%. 2. Feed sheep. Add 10-27% dry chicken manure to the sheep's diet. The daily weight gain and feeding effect of the lamb is equivalent to that of the feed meal. The feed cost is reduced by 17%; the chicken goat is used instead of 18% of the concentrate to feed the dairy goat. Weight gain and milk production are not affected. Milk consumption is reduced by 16% compared to adding soybean cake. 3. Feed the pigs. Adding 40% dry chicken manure to the hog ration resulted in higher daily weight gain and feed remuneration than that of the single feed mixture, and the economic benefit was improved by more than 90%. The meat quality and flavor were stopped 20 days before the slaughter. No effect. 4. Feed chickens. Add 5% dry chicken manure to the feed and feed 1-28 day-old chicks. Use feed ingredients for their growth, so that according to the specific biological characteristics of different species, the production direction, production performance, production stage, gender, and different Different nutrient levels are used during the season to give full play to the growth potential of pigs and improve the economic benefits of feed nutrition. According to reports, lean-type pigs need to obtain higher lean meat ratios, require diets containing relatively high levels of lysine, and grow-finish pigs to withdraw from diets with vitamins, trace elements, and even large quantities within 20 days of the end of the finishing process. Calcium, phosphorus, and sodium do not affect growth performance. For gilts to obtain better daily gain and feed efficiency, they need to add more protein than quail boars, increase appetite and ensure sufficient amounts of pigs in summer. When eating, it is necessary to increase the nutrient concentration of the feed, especially to increase the feed's amino acids, vitamins and trace elements, while adding sodium chloride, sodium bicarbonate and other electrolytes, in order to promote food intake, to ensure the production potential.
