Application of feed additives




1. Chicken

Chicken’s digestive tract is relatively short and the intestinal mucosal barrier is fragile. Under intensive breeding conditions, compared with animals with long digestive tracts, they are more susceptible to harmful microorganisms, leading to various diseases. The use of feed additives is one of the effective means to prevent and treat intestinal diseases and improve the performance of broilers and layers. The growth rate of broilers is fast, and the intensive production is greatly affected by the environment. The application of feed additives can improve the balance of intestinal flora, reduce the incidence and mortality of intestinal diseases, increase slaughter weight, reduce feed and meat ratio, and reduce Emissions of harmful gases such as ammonia and hydrogen sulfide in the chicken house can improve product quality. The application of feed additives in layer breeding can not only prevent diseases, improve production performance and feed remuneration, but also improve egg quality. Studies have shown that adding feed additives to the diet of laying hens can increase the Hastelloy unit of the eggs, reduce the cholesterol content of the eggs, and have the effects of improving the thickness of the eggshell and reducing soft-shell eggs.

2.Pig

Current research and application show that feed additives have achieved good application effects in the breeding of piglets, sows and fattening pigs. Adding feed additives to piglet diets can promote piglet intestinal development, improve intestinal health, reduce diarrhea rate, and increase piglet growth rate and feed conversion rate. For lactating piglets, adding feed additives helps to establish a dominant flora of probiotics; for weaned piglets, it can improve the adverse effects of diarrhea and growth retardation caused by factors such as the secretion of digestive enzymes and the antigenicity of the diet. Studies have shown that the use of feed additives in sow diets can improve intestinal health and improve sow immunity and reproductive performance. After adding feed additives, it can improve the ability to adjust the balance of the bacterial flora in the gastrointestinal tract, increase the feed intake of the sow during lactation, inhibit weight loss, increase the fat and protein content in the milk of the sow, and improve the survival rate of weaned piglets and weaned piglets body weight. Adding feed additives to the fattening pig diet can increase feed intake and feed conversion rate, improve health, shorten the fattening period, and have the effect of improving quality and reducing environmental pollution. Studies have shown that adding feed additives can reduce the diarrhea rate of fattening pigs, improve immunity, increase feed intake and feed digestibility, thereby increasing the utilization rate of diets and reducing the feed-to-meat ratio. In addition, feed additives have a certain promoting effect on increasing intramuscular fat and increasing the content of essential fatty acids, which can improve the quality of pork.

3. Ruminants

Studies have shown that feed additives can improve the weight gain rate of meat ruminants such as mutton sheep and beef cattle, increase carcass net meat rate, and improve meat quality. For milk-producing ruminants, feed additives can increase milk production, prolong the peak of milk production, increase milk fat rate, reduce the number of somatic cells in milk, and improve milk composition. It also has a certain effect on preventing mastitis and reproductive diseases. For calves whose digestive tract is not well developed, the use of additives can promote the establishment of the calf's gastrointestinal flora, adjust the balance of the flora, and reduce the occurrence of calf diarrhea. In addition, the use of feed additives can promote the weight gain of calves.

4. Aquatic products

The application of feed additives in aquatic products is embodied in two aspects: bait and water purification. Feed additives can improve the micro-ecological balance of aquatic animals, promote growth and development, play a role in preventing and controlling diseases and improving production performance. Probiotics can be colonized in the intestines of fish to promote the growth and development of fish and improve disease resistance. Feed additives for feed can reduce the incidence of prawns and increase survival rate and yield. Feed additives can be used as immunostimulants and adjuvants for aquatic animals to promote the development of immune organs, improve the level of humoral immunity, and improve immune function. This effect has been verified in a variety of aquatic animals. The photosynthetic bacteria and nitrifying bacteria in feed additives can consume organic matter in the water body, remove ammonia nitrogen, hydrogen sulfide, nitrite nitrogen, etc., are important beneficial microorganisms currently applied to improve the aquaculture environment. They are used in aquatic animals such as prawns and Japanese flounder. Good application effects are obtained in breeding.
