Background
The feed additive is a small amount or trace substance added in the production, processing and using processes of feed, and the feed additive is small in dosage but remarkable in effect. The feed additive is a raw material inevitably used in modern feed industry, and has obvious effects on strengthening the nutritive value of basic feed, improving the production performance of animals, ensuring the health of the animals, saving the feed cost, improving the quality of animal products and the like.
The current research and application show that the feed additive has good application effect in the breeding of piglets, sows and fattening pigs. The feed additive is added into the daily ration of the fattening pig, so that the feed intake and the feed conversion rate can be improved, the health condition is improved, the fattening period is shortened, and the effects of improving the quality and reducing the environmental pollution are achieved. Researches show that the additive can reduce the diarrhea rate of fattening pigs, improve the immunity and improve the feed intake and the feed digestibility by adding the feed additive, thereby improving the utilization rate of daily ration and reducing the feed conversion ratio. In addition, the feed additive has certain promotion effects on increasing intramuscular fat and increasing the content of essential fatty acid, and can improve the quality of pork.
With the improvement of the living standard of people, the pork has great market demand on safe, nutritional and high-quality pork. In order to prevent diseases of pigs and improve the growth speed of pork pigs, antibiotics and chemical synthetic drugs are abused in actual production to cause drug residues in pork, destroy the ecological balance among microorganisms in the natural environment, seriously influence the disease treatment of people and the genetic health of people, and can not meet the requirements of people on safe, healthy and high-quality pork.
