Capsaicin is not only safe and non-toxic, but also has the functions about antibacterial, anti-inflammatory, digestive and immune. It is widely used in food, medical, beauty, defense, and military fields. The capsaicin applies in livestock and poultry production, it has obvious effects of inhibiting bacteria and improving production performance, regulating intestinal flora, and improving immunity. It has the potential to replace antibiotics, and has broad application prospects and research significance.
1. Capsaicin applied in production performance of livestock and poultry
(1) Be egg yolk colorant
Capsaicin as a colorant can significantly deepen the color of egg yolk, even orange-red. Capsaicin is also used as a feed additive to improve the quality of egg yolks.
(2) Feed additives for broilers
Capsaicin as a feed additive can significantly improve the feed-to-meat ratio of Avian broilers.
In the 1990s, The University of Texas in the United States has demonstrated that the addition of capsaicin to the feed of white chickens can significantly inhibit Salmonella infection. Researchers believe that it may be because capsaicin stimulates peripheral afferent nerve endings, which in turn produces a variety of infectious changes, reducing the susceptibility of Salmonella in chickens and reducing infections.
(3) Pig feed additives
Capsaicin is also used as a growth-promoting additive in piglet feed. Adding 0.3% to 0.5% of chili powder to the piglet's basic diet can significantly promote the daily weight gain and feed conversion rate of piglets, and improve the piglet's body shape and hair color. Capsaicin can regulate the intestinal flora of pigs, thereby improving the immune capacity of pigs.
(4) Rex Rabbit Feed Additive
Studies have shown that by adding 7.5% paprika to the rex rabbit diet, the rex rabbit's growth performance and feed conversion rate are significantly improved.
2. Capsaicin applied in livestock and poultry regulation flora and immunity
Numerous studies have shown that capsaicin can inhibit the growth and reproduction of a variety of bacteria. Capsaicin can be quickly absorbed by pigs, cattle, and chickens by oral administration, and it can significantly inhibit some of the pathogenic bacteria in the digestive tract. Capsaicin can significantly inhibit the reproduction and growth of yeast, salmonella and E. coli.
3. Capsaicin applied in other aspects of livestock and poultry
In addition to the above effects, capsaicin is also used in the control and treatment of parasites such as intestinal nematodes of livestock, poultry, and pigs, the prevention of plague, and the treatment of inflammation and diarrhea in animals.
At present, as a widely planted cash crop, pepper is low in price, widely used in fields, and has high economic value and social benefits. In livestock and poultry, it has great research value and application space as a broad-spectrum bacteriostatic drug and immunomodulator. With the progress of society, China has paid more and more attention to the safety of animal products and the use of medicines. Natural plant feed additives, as substitutes for antibiotics, will definitely become research trends and hotspots, and have received widespread attention from all walks of life.
