Five kinds of additives which are beneficial to the health of piglets

Piglets play a very important role in the whole growth stage of piglets, and it is very important to strengthen the nutrition of piglets. This paper introduces five kinds of additives which are beneficial to the health of piglets. The introduction is as follows: 1. Vitamin E and biotin recent studies have shown that the use of high dose of vitamin E in piglet feed can enhance pig immunity, reduce the mortality of weaned piglets, prevent the occurrence of edema disease of piglets and reduce weaning stress. In practical application, the addition amount of vitamin E is 40g / ton. Biotin, mainly as a coenzyme, participates in a variety of important metabolism, which can promote the growth of piglets and improve feed conversion rate. At present, the biotin content sold in the market is generally 2%, and the addition amount is 30g / ton, which can achieve better feeding effect. 2. Enzyme preparation due to poor digestive function of piglets and obvious shortage of digestive enzymes, it is necessary to add enzyme preparation to piglet feed to make up for the deficiency of digestive physiology of piglets and improve the utilization rate of feed. Amylase, protease, lipase, cellulase and other compound enzymes are ideal for enzyme preparation. According to the experiment, adding 0.1% compound enzyme to the diet of 35-day-old weaned piglets could increase daily gain by 8% and feed conversion rate by more than 35%. In order to increase the feed intake of piglets, improve the bad smell in the feed and increase the palatability, seasoning agents are usually added to the piglet feed, such as American suckling pig incense, suckling pig treasure and so on. It is reported that by adding suckling pig incense and suckling pig treasure to the feed, the daily gain of piglets can be increased by 10%-18%, and the feed intake can be increased by 10%-15%. The flavoring agent is generally 40000g / ton. 4. Acidifier adding citric acid, fumaric acid, calcium formate and other organic acids to piglet feed can reduce the PH value of feed and gastrointestinal tract, promote the growth and development of piglets, improve feed utilization rate, and control the reproduction of harmful microorganisms. effectively prevent the occurrence of piglet diseases. It is reported that adding 1.5%-2% fumaric acid to piglet feed can increase piglet daily gain by 8%, feed intake by 5.2%, and feed utilization rate by 4.4%. Adding 1-1.5% calcium formate to the diet of piglets could increase daily gain by 2.8%-4.9%, and significantly reduce the incidence of dysentery in piglets. Microbial preparation is a new type of growth-promoting agent, which can maintain the dynamic balance of digestive tract bacteria, inhibit and repel dominant bacteria, such as Escherichia coli and salmonella, increase lactic acid, stabilize the PH level of digestive tract, regulate the balance of electrolytes in intestinal tract, prevent the occurrence of diarrhea, and improve the immune stress ability of animals. It is reported that when piglets are fed probiotics directly from 1 to 2 days after birth, the survival rate of weaned piglets can be increased by 45.5%, while it is also reported that the addition of microbial preparations can increase the survival rate of piglets by 7% and reduce the rate of dysentery by 20%. In practical application, 2kg / ton of probiotics can be added to piglet feed. -Yes, but we don't use seasoning and microbial preparations now, and the feeling effect is also good.
