Low-emission meat duck feed and preparing method thereof

Abstract

The invention discloses low-emission meat duck feed and a preparing method thereof. The feed is prepared from corn, peanut meal, corn DDGS, 46% cottonseed meal, wheat flour, nucleotide dregs, bolete, choline chloride, low-emission additives, vitamin premixes and organic microelement chelate. The low-emission meat duck feed and the preparing method have the advantages that scientific compatibility is carried out on the low-emission meat duck feed, the ideal feeding effect can be achieved, and the low-emission meat duck feed and the preparing method are efficient and environmentally friendly; low emission of nitrogen, phosphorus, manganese, zinc, copper and the like is achieved during breeding, and good social benefits and good economic benefits can be created. The feed is free of negative effects on the growing performance of meat ducks; the feed-weight ratio can be further improved; the use ratio of protein resources is increased, the economic benefits are increased, and excretion of the nitrogen is reduced; the manganese apparent use ratio, the zinc apparent use ratio and the copper apparent use ratio of the meat ducks can be increased, and the excretion amount of the manganese, the excretion amount of the zinc and the excretion amount of the copper are decreased. The use ratio of the nitrogen and the use ratio of the phosphorus can be effectively increased, the excretion amount of the nitrogen in excrement and the excretion amount of the phosphorus in the excrement can be decreased, and pollution to the environment can be reduced.

Description

technical field [0001] The invention relates to animal feed, in particular to a low-emission meat duck feed and a preparation method thereof. Background technique [0002] In 2011, my country had 1.525 billion ducks on hand and 3.94 billion ducks on the market, accounting for more than 80% of the world's total. It is the world's largest meat duck breeding country, and this proportion is increasing year by year. However, with the increase of livestock and poultry breeding, the excrement discharge will increase accordingly, and the pollution of the environment will become increasingly serious. The annual discharge of livestock and poultry manure in the country has increased year by year from 1.88 billion tons in 1988 to 3.5 billion tons in 1998. It is predicted that the total amount of manure in the country will reach 4.244 billion tons in 2020. N and P are the main nutrients in the feed, and they are also the two elements most likely to damage the ecological environment in...

AI Technical Summary

Problems solved by technology

According to statistics, about 65% of the N and 70% of the P ingested by livestock and poultry are not fully utilized and excreted, which not only causes waste of nutrients, but also leads to serious pollution of the environment

In recent years, in order to increase the growth rate of livestock and poultry and enhance their disease resistance, livestock and poultry feed usually contains a certain amount of Cu, Zn, Mn and other trace element additives, which may have a promoting effect in terms of purely considering animal production performance, but for some The exact absorption mechanism of some trace elements is still unclear, so they are rarely absorbed by animals, and more are excreted through feces, causing environmental pollution

[0003] Because the absorption rate of inorganic trace elements is only 2% to 10%, many farms at home and abroad use a large amount of high-zinc and high-copper feed, resulting in serious excess zinc and copper residues in meat, eggs, dairy products and animal manure, and to serious pollution of the environment
