Description

Composite premix for pigs and preparation method thereof

technical field

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

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. Looking at the process of animal husbandry production from the perspective of environmental protection, it is not difficult to see that animal husbandry has become a source of pollution that cannot be ignored.

The pollution caused by pig farming to the environment is rooted in feed. Feed is the foundation of the pig industry and the basic guarantee for the production of high-quality and safe pork products. It is also the source of excrement pollution in the pig industry and an important factor in causing "environmental hazards" in the pig industry. In order to add trace elements such as copper, iron, zinc, manganese, selenium, etc. in pig feed, excessive use of inorganic salts, abuse of antibiotics and low digestibility of pig feed lead to a large amount of feed and trace elements without digestion and absorption. It is directly excreted from the body or deposited in animal products, which not only seriously pollutes the environment, but also affects the edible safety of animal products and causes a waste of feed resources.
