Composite pre-mix material for pig and preparation thereof

Abstract

The invention provides a composite pre-mix material used for pigs, which is characterized by comprising components in the following weight percent: 20 percent to 50 percent of calcium carbonate, 1 percent to 25 percent of calcium hydrophosphate, 2.01 percent to 27 percent of synthetic amino acid, 0.5 percent to 17 percent of organic microelement, 0.001 percent to 0.2 percent of potassium iodide with 5 percent of purity, 1.1 percent to 5.5 percent of enzyme preparation, 5 percent to 10 percent of salt, 0.2 percent to 2 percent of composite multi-fiber used for pigs, 0.3 percent to 2 percent of antioxidant, and 1 percent to 40 percent of carrier. The invention also provides the preparation method of the composite pre-mix material used for pigs. The product of the invention reduces the addition of phosphorus and improves the ration nutrient digestion rate by adding the enzyme preparation , so as to reduce the emission of nitrogen and the phosphorus; provides microelements, such as copper, iron, zinc, manganese, selenium, etc. by adding composite amino acid chelate complex, which not only greatly reduces the emission of the microelements and prevents environmental pollution, but also prevents the sediment of the microelements in pork, and ensures the eating safety of the pork.

Description

technical field

[0001] The invention relates to a feed additive for livestock and poultry, in particular to a compound premix for pigs; the invention also relates to a preparation method of the compound premix. Background technique

[0002] While the pig industry provides humans with a large amount of high-quality pork products, it also discharges a large amount of excrement and harmful gases to the environment, polluting the environment. With the continuous improvement of human living standards, the demand for pork continues to increase, resulting in larger and larger pig production scales, higher and higher levels of modernization and intensification, that is, a sharp increase in the number and density of pigs. A large amount of excrement and waste produced in the process of livestock and poultry feeding and live processing has become more and more prominent in the pollution of human beings, other organisms and the living environment of livestock and poultry themselves.
