Application of sodium dichloroacetate in preparation of low protein feed for pigs

Abstract

The invention discloses application of sodium dichloroacetate in preparation of a low protein feed for pigs. The inventor firstly classifies raw materials into three types; the first type is known as a micro-class raw material with the mixing proportion less than 2 percent, the second type is known as a medium-class raw material with the mixing proportion greater than 2 percent and less than 5 percent, and the third type is known as a large-class raw material with the mixing proportion greater than 5 percent. The low protein feed for the pigs is prepared by the following steps: firstly, mixing the first type of feed raw materials, fully and uniformly mixing the raw materials through a stirrer, then mixing the raw materials with the medium-class raw materials, thus obtaining a mixture, and finally, mixing the mixture with the large-class raw materials, thus obtaining the amino acid metabolism thrift-based low protein feed for the pigs; granulating the mixture according to the particle size of 8 to 12 mm; and transferring the particles into a drying machine for drying at the temperature of 95 to 105 DEG C, thus preparing a particulate feed finished product. The feed is wide in source, low in cost and comprehensive in nutrition; the level of coarse proteins in the feed can be obviously reduced; the growing performance of the animal cannot be affected; and the low protein feed is applicable to large-scale production.

Description

technical field [0001] The invention belongs to the field of livestock and poultry breeding feed, and in particular relates to the application of sodium dichloroacetate in preparing pig low-protein feed. [0002] technical background [0003] In recent years, environmental pollution caused by nitrogen emissions has become increasingly serious with the continuous expansion of the scale and intensification of livestock and poultry farming. At present, the estimated value of global nitrogen emissions from livestock and poultry is as high as 89-164 million tons; the nitrogen emissions from livestock and poultry in my country is about 30 million tons, of which the nitrogen emissions from monogastric animals (mainly pigs) account for about 30 million tons of total nitrogen emissions 60% of. At the same time, the shortage of protein resources is a common problem faced by the whole world; in 2015, China imported about 81.69 million tons of soybeans, and the import dependence of fishm...
