Several additive additives for piglets
To maintain a high growth rate and a high survival rate of piglets, it is necessary to meet their needs. In addition to using conventional feed, adding vitamins, minerals, and trace elements, it is necessary to rationally use some additives in accordance with the physiological characteristics of piglets. Here are some useful additives for piglets, for the majority of pig farmers reference! First, vitamin E and biotin. Recent studies have shown that using high doses of vitamin E in piglet diets can increase pig immunity, reduce weaning piglet mortality, prevent edema disease in piglets, and reduce weaning stress in piglets. In practical applications, the amount of vitamin E added is 40-60 g/ton. Biotin is mainly used as a coenzyme to participate in various important metabolisms, which can promote the growth of piglets and improve the feed conversion rate. Currently, the biotin content sold in the market is generally 2%, and the added amount is 30-50 g/ton, which can achieve better feeding results. Second, enzyme preparations. Due to poor digestive function of the gastrointestinal tract of piglets, digestive enzymes are obviously insufficient. Therefore, it is necessary to add enzyme preparations to the feed of the piglets to compensate for the lack of digestive physiology of the piglets and increase the utilization rate of the feed. The enzyme preparation preferably contains a complex enzyme such as an amylases, a protease, a lipase, and a cellulase. According to the experiment, adding 0.1% compound enzyme to the 35-day-old weaned piglet diet can increase the daily weight gain by 8.29% and the feed conversion rate by 38.89%. Third, flavoring agents. In order to increase the feed intake of piglets, to improve the bad odors in the feed, and to increase the palatability, flavouring agents such as U.S. suckling pigs and suckling pigs are usually added to the feed for piglets. It has been reported that adding piglet and suckling pig to the feed can increase the daily gain of piglets by 11% to 18% and the feed intake by 10% to 15%. The amount of flavoring agent in the feed is generally 400-500 g/ton. Fourth, acidification agent. The addition of citric acid, fumarate, calcium formate, and other organic acids to the piglet diet can reduce the pH of the feed and the gastrointestinal tract, promote the growth and development of the larvae, improve feed utilization, and control the reproduction of harmful microorganisms, effectively preventing piglet diseases. (as follows, etc.) occur. According to reports, the addition of 1.5%-2% fumaric acid to the piglet diet can increase the average daily gain of piglets by 9%, feed intake by 5.2%, and feed utilization by 4.4%. According to another report, adding 1%-1.5% calcium formate to the diet of piglets can increase the daily gain by 2.8%-4.9%, and it can significantly reduce the incidence of diarrhea in piglets. Fifth, microbial preparations. Microbiological agents (such as probiotics, etc.) are new growth-promoting agents that maintain the dynamic balance of gut bacteria, inhibit and reject pathogens such as pathogenic E. coli, Salmonella, etc.; increase lactic acid and stabilize digestive tract PH The level regulates the electrolyte balance in the intestine, prevents the occurrence of diarrhea, and improves the animal's immune-stress abilities. According to reports: Feeding of probiotics directly from piglets 1-2 days after birth can increase the survival rate of weaned piglets by 4%-5%. It is also reported that the addition of microbial preparations can increase the survival rate of piglets by 7% and the rate of dehydration by 20%. %. In practice, prebiotics can be added to piglets at 2-3 kg/ton.
