Allicin is a kind of feed additive which is widely used in recent years. Due to its safety, low cost, green color, non-toxicity and no residue, it is favored by the majority of farmers. Adding proper amount of allicin to the diet to grow pigs. It has an immeasurable effect.
Allicin contains natural garlic oil with a strong garlic smell. Garlic oil is mainly composed of diallyl disulfide and diallyl trisulfide, with a total content of 80% or more, strong antibacterial activity, causing diarrhea, diarrhea caused by dysentery bacillus, typhoid bacillus, etc., caused by Pasteurella Pneumonia, bronchitis has a significant effect. Allicin has a pure and natural strong fragrance. It can replace other flavoring agents in the feed. Adding 50ppm~150ppm of allicin to the feed can improve the odor of the feed, stimulate the pigs to produce a strong attracting effect, and increase the appetite. The feed intake also increases, which in turn increases the net weight.
The physicochemical properties of allicin mainly depend on garlic oil, which is light yellow to brownish red liquid with a density of 1.050~1.095 and a refractive index of 1.550~1.580. It is soluble in most non-volatile oils, partially soluble in ethanol, insoluble in water, glycerin and propylene glycol. . Strong acid, strong oxidants and UV rays can cause deterioration.
The addition of allicin to the swine feed improves the aroma and quality of the meat. To make the flavor thicker, the method of adding allicin to the feed is simple and easy, as long as the garlic is soaked, peeled, sliced, dried (or dried), and then pulverized. Volatile sulfur compounds in allicin can drive away the sucking of feed and feces by mosquitoes and flies. Garlic is converted into garlicin under the action of enzymes in pigs. It can enter the pit after excretion of urine, which can prevent mosquitoes from flying. Reproduction in feces and larvae, reducing harassment of mosquitoes and animals, reducing disease transmission and improving the surrounding environment.
The addition of allicin can maintain the original fixed flavor of the original feed, although it will release a special smell, but a large number of test results show that the pigs prefer the smell of garlic. Adding 25% allicin to 200 mg per ton of the healthy and disease-free Du Changda binary hybrid weaned pig diet at the age of 20 days. Antibiotics were added to the control group. The results showed that the day of the addition of the allicin group was compared with the control group. The weight gain increased by 16.5%, the feed-to-weight ratio decreased by 13%, and there was no significant difference in feed intake, indicating that allicin has a growth-promoting effect on piglets. Allicin can significantly increase weight gain and improve feed returns.
Allicin can also be used to control many swine diseases such as ascariasis, ascariasis, paratyphoid fever, gastroenteritis, rheumatism and tetanus.
In summary, the addition of allicin to the feed of piglets is an effective method to prevent environmental pollution and promote the development of aquaculture, and has broad prospects for development and application.
