Problems solved by technology

The protein materials produced by its high-protein substances are mainly 43% soybean meal, expanded soybean and super steam fish meal. If protein materials such as 43% soybean meal are not used or used less, although it can reduce fecal nitrogen and urine nitrogen emissions, it will affect the mother. Pig reproductive performance and production performance

Abstract

The invention discloses a low-protein balanced amino acid pig feed eaten by lactating sows. The low-protein balanced amino acid pig feed comprises 50-75 parts of Zea mays L., 10-20 parts of 43% soybean meal, 3-8 parts of extruded soybeans, 2-4 parts of super steam fish meal, 0.5-2 parts of soybean oil, 0.3-1.5 parts of amino acid compound bags, 0.01-0.1 part of compound enzyme preparation, 0.01-0.1 part of single probiotic preparation and 0.5-6 parts of lactating sow premix. According to the pig feed, the use amount of the 43% soybean meal is reduced, nitrogen emission pollution of the pig industry is reduced, the nitrogen pollution of the pig industry to the environment is relieved, high efficiency of reproductive performance of lactating sows and consistency of animal performance can be kept, the pig industry is green, environmentally friendly and low in cost, and dependence on imported soybeans can be reduced. The invention further discloses a preparation method of the low-protein balanced amino acid pig feed.

Description

technical field [0001] The invention relates to the technical field of pig feed, in particular to a low-protein balanced amino acid pig feed for lactating sows and a preparation method thereof. Background technique [0002] The aquaculture industry is a huge industry that feeds economic animals (pigs, cattle, chickens, ducks or aquatic products) and provides meat, eggs, milk and aquatic products for the society. During the breeding process, animals will inevitably discharge pollutants such as feces, urine and methane gas to the environment. Common pollutants in feces include nitrogen, phosphorus, common mineral elements and heavy metal elements. The generation of pollution has become an important factor restricting the development of the aquaculture industry, and it is also an urgent problem that needs to be solved urgently. [0003] A classic study found that when dietary protein was reduced by 4% or 8%, the fecal nitrogen and urine nitrogen emitted by pigs to the environm...
