Problems solved by technology

However, due to the influence of traditional breeding concepts and the existing market, the protein content of the low-protein diets currently studied and applied is still relatively high (decreasing by about 1-2 percentage points), and there are fewer types of amino acids (usually lysine) balanced. acid, methionine)
This somewhat limits the benefits of this technology (10-20% reduction in nitrogen content in pig excreta)

Abstract

The invention relates to a composite premix for reducing nitrogen pollution in the pig raising industry and a preparation method thereof. The composite premix comprises the following components in part by weight: 3 to 5 parts of L-isoleucine, 3 to 5 parts of L-lysine hydrochloride, 8 to 10 parts of DL-methionine, 3 to 5 parts of L-threonine, 3 to 5 parts of L-valine, 3 to 5 parts of DL-tryptophan and 65 to 75 parts of carrier; and the method comprises the following steps of: mixing and screening all amino acids and 1 / 4 weight carrier, adding the rest carrier, and uniformly mixing the components for 10 to 15 minutes to obtain a product. Compared with the prior art, the composite premix can reduce the protein in daily ration of piglets by 3 to 4 percent, reduce the nitrogen content of the piglet excrement by 25 to 35 percent and improve the survival rate of the piglets, is simple and convenient to use, and is easily used by various farms and feed factories.

Description

technical field [0001] The invention relates to a composite premix and a preparation method thereof, in particular to a composite premix for reducing nitrogen pollution in pig farming and a preparation method thereof. Background technique [0002] The pollution caused by animal husbandry to the environment cannot be ignored. It has attracted great attention from all over the world. Especially the pollution of the environment by pig farming is the most prominent. China ranks first in the world in both the number of pigs on hand and the output of pork. With the rapid development of the pig industry, the degree of scale and intensification is getting higher and higher, and the pressure on environmental governance is also increasing. These pollutants have caused serious pollution to the soil, water sources, air and the living environment of the surrounding residents, which not only affect people's health, but may also cause the spread and epidemic of diseases. The organic po...
