Piglets play a very important role in the whole growth stage of pigs. It is very important to strengthen the nutrition of piglets. This article introduces five additives that are beneficial to the health of piglets. Introduced as follows:
1. Vitamin E and biotin
Recent studies have shown that the use of high doses of vitamin E in piglet feed can enhance the immunity of pigs, reduce the mortality of weaned piglets, and prevent the occurrence of edema disease in piglets and reduce the weaning stress of piglets. In practical applications, the amount of vitamin E added is 40 to 60 g/ton. Biotin is mainly used as a coenzyme and participates in a variety of important metabolisms, which can promote the growth of piglets and increase the feed conversion rate. At present, the biotin content currently sold in the market is generally 2%, and the added amount is 30-50 g/ton, which can achieve better feeding effect.
Second, the enzyme preparation
Due to the poor digestive function of the gastrointestinal tract of piglets, the digestive enzymes are obviously insufficient. Therefore, it is necessary to add enzyme preparations to the feed of piglets to make up for the deficiency of digestive physiology of piglets and improve the utilization rate of feed. The enzyme preparation is preferably a complex enzyme such as amylase, protease, lipase and cellulase. According to the experiment, adding 0.1% compound enzyme to the diet of 35-day-old weaned piglets can increase the daily gain by 8% and increase the feed conversion rate by more than 35%.
Third, the flavoring agent
In order to improve the feed intake of piglets, improve the bad smell in the feed, and increase the palatability, seasonings such as the American suckling pig and the suckling pig are usually added to the piglet feed. According to reports: the addition of suckling pig and piglet in the feed, piglet daily weight gain can be increased by 10% to 18%, feed intake increased by 10% to 15%. The flavoring agent is generally 400 to 500 g/ton.
Fourth, acidifier
Adding organic acids such as citric acid, fumaric acid and calcium formate to piglet feed can reduce the pH of feed and gastrointestinal tract, promote the growth and development of piglets, improve feed utilization, and control the reproduction of harmful microorganisms, effectively preventing piglet diseases. occur. It has been reported that the addition of 1.5% to 2% fumarate to piglet feed can increase piglet daily gain by 8%, feed intake by 5.2%, and feed utilization by 4.4%. Adding 1~1.5% calcium formate to the piglet diet can increase the daily gain by 2.8%~4.9%, and can significantly reduce the incidence of dysentery in piglets.
5. Microbial preparations
Microbial preparation is a new type of growth promoter, which maintains the dynamic balance of digestive bacteria, inhibits and rejects the original bacteria, such as the causative Escherichia coli, Salmonella, etc.; increases lactic acid, stabilizes the pH level of the digestive tract, regulates the intestine electrolyte balance in the road, to prevent the occurrence of diarrhea, improve the animal's immune stress capability and other functions. It is reported that: starting from 1 Piglets 1-2 days after birth Probiotics fed directly, can increase the survival rate of piglets weaned 4-5%, and also reported adding microbial preparation can improve the survival rate of piglets 7%, a 20% reduction of diarrhea . In practice, the probiotics may be 2 to 3 kg / ton in piglet feed.
