Environment-friendly ecological broiler feed and broiler breeding method for reducing broiler manure nitrogen phosphorus discharge

Abstract

The invention discloses an environment-friendly ecological broiler feed which comprises, by weight, 528 parts of corn, 100 parts of wheat, 275 parts of 46% soybean meal, 5 parts of soya-bean oil, 50 parts of 60% high protein powder, 15 parts of stone flour, 3 parts of salt, 13.5 parts of calcium hydrogen phosphate, 1.3 parts of 99% methionine, 4.05 parts of 65% lysine, 0.25 part of anti-oxidants, 0.31 part of vitamin for chicken, 0.13 part of colistin sulfate, 0.11 part of phytase, 0.9 part of probiotics, 0.15 part of kemzyme, 2.5 parts of choline, 0.5 part of salinomycin, 1 part of broiler multi-minerals, 0.5 part of 10% bacitracin zinc, and 0.5 part of Youpuding. The breeding method using the broiler feed is a broiler breeding method for reducing broiler manure nitrogen phosphorus discharge; because of the addition of phytase and probiotics in the feed, the nitrogen and phosphorus utilization rates of broilers are effectively improved, the excretion amounts of nitrogen and phosphorus are decreased, and the utilization rate of the feed is improved.

Description

technical field [0001] The invention relates to a broiler feed and a feeding method, in particular to an environment-friendly ecological broiler feed and a broiler feeding method for reducing nitrogen and phosphorus emissions from chicken manure. Background technique [0002] Since the 1980s, my country's poultry industry has developed very rapidly, and the development of chicken farms has gradually moved towards scale, intensification and factoryization, and chicken farms with more than 100,000 chickens have sprung up like mushrooms after rain. With the construction of large-scale chicken farms, a large amount of feces and harmful gases emitted by chickens have continuously aggravated environmental pollution, which not only seriously affects the health and production performance of chickens, but also poses a great threat to human health. [0003] Chickens have a short digestive tract and low digestibility. Usually, 20% to 25% of the nutrients in the feed are not digested an...

Problems solved by technology

[0010] Theoretically speaking, the existing feed has been at a relatively suitable level after years of research. In conventional technology, phytase and probiotics have been directly added to the existing feed. For example, Chinese patent 200810136835 discloses a Feed, the plan is to directly add 1.5 parts of prebiotics and 0.3 parts of phytase to the existing feed. Since the original feed composition is a relatively suitable level, after adding phytase and probiotics, the content of the feed is improved. conversion rate, the nutritional level of the original feed components will appear too high, resulting in the excess of some nutrients, making the nutritional level of broilers unbalanced. It is precisely because of the imbalanced nutritional level that it is also not conducive to reducing the discharge of nitrogen and phosphorus. Practice has shown that the current Some add phytase and probiotic feed to feed broiler chickens, and the discharge of chicken manure nitrogen is more than 1.49%, and the discharge of phosphorus is more than 1.20%. The feed disclosed in Chinese patent 200810136835 has been tested, and the discharge of chicken manure nitrogen is 1.50% %, the discharge of phosphorus is 1.21%, and the feed-to-meat ratio (feed-to-meat ratio refers to the amount of feed consumed by raising livestock and poultry to gain one kilogram of weight. It is an important indicator for evaluating feed remuneration, and it is also the basis for preparing production plans and financial plans. The important basis for this is that a high feed-to-meat ratio means more feed is used, but less meat is grown; on the contrary, a low feed-to-meat ratio means less feed is used, but more meat is grown) at 1.85
