Description
Technical Field
The invention relates to the technical field of pig feed, and particularly relates to low-protein balanced amino acid pig feed for lactating sows and a preparation method thereof.
Background
The breeding industry is a huge industry for feeding economic animals (pigs, cows, chickens, ducks or aquatic products) and providing meat, eggs, milk and aquatic products for the society. The animals inevitably discharge pollutants such as excrement, urine, methane gas and the like to the environment in the breeding process, wherein the common pollutants in the excrement comprise nitrogen, phosphorus, common mineral elements, heavy metal elements and the like. The generation of pollution becomes an important factor for restricting the development of the breeding industry and is an urgent problem to be solved.
Classical studies have found that the reduction of feed protein by 4% or 8% results in a reduction of 0.2% -3.5% and 20.7% -44.7% in fecal and urinary nitrogen respectively emitted by pigs (T CanH, 1998). Therefore, the reduction of the generation of pollutants through the regulation and control of the nutrition of the feed is a better technical measure. At present, due to the particularity of the lactating sows, the feed of the lactating sows is high in protein, so that the content of fecal nitrogen and urinary nitrogen discharged into the environment by the lactating sows is higher than that of other animals. 43 percent of soybean meal, expanded soybean, super steam fish meal and other protein raw materials in the traditional high-protein lactating sow feed formula are accumulated in a dosage of more than 28 percent, and the crude protein content of the feed is generally 18 percent or more. The protein raw materials generated by the high-protein substances mainly comprise 43% of soybean meal, expanded soybeans and super steam fish meal, and if the protein raw materials such as the 43% of soybean meal are not adopted or are used less, the emission of fecal nitrogen and urinary nitrogen can be reduced, but the reproductive performance and the production performance of sows can be influenced. Therefore, if other substances are added to reduce high protein in the formula (namely, 43% of protein raw materials such as soybean meal and the like are reduced) and the reproductive performance and the production performance of the sow can be ensured, the reduction of the content of fecal nitrogen and urinary nitrogen discharged into the environment by the sow can be realized.
