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 sho

Embodiment 1

[0026] The environmental protection ecological type broiler feed described in this embodiment is composed of: 528 parts of corn, 100 parts of wheat, 275 parts of 46% soybean meal, 5 parts of soybean oil, 50 parts of 60% high protein powder, 15 parts of stone powder, 3 powders of salt, Calcium hydrogen phosphate 13.5 parts, 99% methionine 1.3 parts, 65% lysine 4.05 parts, antioxidant 0.25 parts, chicken vitamin 0.31 parts, antiene sulfate 0.13 parts, phytase 0.11 parts, prebiotics 0.9 parts , 0.15 parts of Babaowei, 2.5 parts of choline, 0.5 parts of salinomycin, 1 part of broiler multimine, 0.5 parts of 10% bacitracin zinc, and 0.5 parts of youptin; the above are all parts by weight

[0027] The beneficial effect of the environmentally friendly ecological broiler feed described in this example is: adding phytase to the feed effectively improves the utilization rate of phosphorus in broilers, reduces the excretion of phosphorus, and increases the retention of nitrogen at the sam...

Embodiment 2

[0030]The broiler raising method described in this embodiment to reduce nitrogen and phosphorus discharge from chicken manure specifically includes the following steps:

[0031] A. Select the chicks;

[0032] B. Thoroughly clear the environment inside and outside the chicken house; raise the temperature of the chicken house to 33°C 5 hours before entering the chicks, and control the humidity at 65%;

[0033] C. 1-7 days old: The initial temperature of brooding is 33°C, and then it will drop by 1 degree every day, using 24 hours of light, the light intensity is 2.7 watts per square meter, the humidity is controlled at 70%, and the feed B is fed;

[0034] D, 8-14 days old: the temperature of the chicken house is controlled at 26°C, the lights are turned off for 1 hour at night, the ventilation is done well, the light intensity is 2.7 watts per square meter, the humidity is controlled at 65%, and feed B is fed;

[0035] E, 15-21 days old: the temperature is controlled between 24...

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...
