Later-period compound feed for environment-friendly nonresistant broilers

Abstract

The invention relates to a later-period compound feed for environment-friendly nonresistant broilers. The compound feed has high animal digestion utilization rate, can maintain the flora balance of digestive tracts effectively and is low in cost, and environment pollution is reduced. The later-period compound feed is prepared from the following raw materials in part by weight: 580 to 630 parts ofcorn, 90 to 120 parts of bean pulp, 85 to 105 parts of wheat middlings, 25 to 45 parts of vegetable dregs, 50 to 70 parts of distiller dried grain with soluble (DDGS), 20 to 40 parts of corn albumen powder, 20 to 30 parts of meat bone meal, 3 to 7 parts of calcium carbonate, 0.3 to 0.7 part of composite vitamin, 10 to 30 parts of grease, 2.0 to 6.0 parts of lysine, 0.2 to 0.6 part of methionine, 0.1 to 0.5 part of threonine, 2.0 to 3.0 parts of table salt, 0.3 to 0.7 part of antioxidant, 0.3 to 0.7 part of microecological preparation and 0.1 to 0.5 part of phytase.

Description

1. Technical field: [0001] The invention relates to a feed, in particular to an environment-friendly and non-resistance broiler late-stage compound feed without adding additional trace elements and antibiotics. 2. Background technology: [0002] The current products have the following shortcomings: 1. The amount of trace elements added in the late growth period of broilers is the same as that in the early and middle stages, which increases the cost and pollutes the environment; 2. The content and utilization rate of trace elements in the basic diet are not considered, blindly Increase the amount of trace elements added. 3. The use of high doses of drug feed additives, the abuse of antibiotics leads to drug resistance; 4. The use of some miscellaneous meal, meat and bone meal and other feed materials with relatively low digestibility, resulting in low energy-to-egg ratio and low feed utilization. Excessive excretion of nitrogen, phosphorus and other minerals aggravates the e...

[0002] The current products have the following shortcomings: 1. The amount of trace elements added in the late growth period of broilers is the same as that in the early and middle stages, which increases the cost and pollutes the environment; 2. The content and utilization rate of trace elements in the basic diet are not considered, blindly Increase the amount of trace elements added

3. The use of high doses of drug feed additives, the abuse of antibiotics leads to drug resistance; 4. The use of some miscellaneous meal, meat and bone meal and other feed materials with relatively low digestibility, resulting in low energy-to-egg ratio and low feed utilization. Excessive excretion of nitrogen, phosphorus and other minerals aggravates the environmental burden; 5. Did not try to use probiotics, always put the use of antibiotics in the first place, ignoring the need to establish normal intestinal flora in order to make the intestinal tract healthy; 6. The quality of raw materials used is unstable, resulting in inconsistent product quality in the market; 7. Following the design of similar products in the market, only considering the immediate market demand, without long-term consideration
