Application of allicin in aquaculture

Allicin is the general name for the main biologically active ingredients in garlic. In our country, garlicin has a long history as a medicine. It is a broad-spectrum antibacterial drug with many biological functions such as anti-inflammation, lowering blood pressure, lowering blood fat, inhibiting platelet aggregation, anti-cancer anti-virus, and so on. Aquaculture feed additives are researched, developed and utilized according to the development of rural aquaculture, and have the value of promotion. Practice has shown that allicin can significantly improve production performance, reduce morbidity, reduce mortality, and increase aquaculture efficiency. It can partially replace antibiotics to reduce the antibiotic resistance produced by microorganisms and have a beneficial effect on the health of livestock and fish. The addition of allicin to feed can be used as a way to solve antibiotic problems.
The functional role of allicin bactericidal effect of allicin on animal husbandry and aquatic animal diseases caused by Escherichia coli, Salmonella, Pseudomonas aeruginosa and other have a good inhibition and killing effect, especially for dairy cows and pigs enteritis, grass carp gizzard disease Diseases such as erythroderma and fish outbreaks are particularly effective. They are currently effective drugs for rural areas to save investment in the development of aquaculture and prevent and control diseases.
Improve the palatability of feed In recent years, many farmers often use feeds with poor palatability or add some growth-promoting agents to reduce the feed cost, causing feed intake or decline in feed intake. Causes the animals to grow slowly and thin. By adding allicin can significantly improve the palatability of feed and increase feed intake.
Allicin attracts animals through the odor of garlic, giving them appetite, thereby increasing feed intake. Most animals, especially fish, like the smell of allicin.
Improve production performance Allicin can not only increase the feed intake of animals, but also can prevent and cure various diseases, improve immune function, improve the function of various tissues in animals, promote gastrointestinal motility and secretion of various digestive enzymes, and increase livestock husbandry. Digestion and utilization of feed, so as to improve production performance and reduce feed costs.
Allicin can be changed to garlic cloves under the action of enzymes and excreted in the form of excrement. This can prevent the breeding and growth of pests in the culture and improve the environment of the pens and ponds.
The use of garlic and the amount of additives to add fresh garlic, mash, chopped or minced meat machine made of garlic, and then added to the feed. Or mix fresh garlic with feed ingredients and smash it. The proportion of fresh garlic in feed is 1%~10%, which is added according to the size of livestock and poultry, generally divided into small, medium and large types (ie, 1%~2%, medium 2%~6%, large) 8%~10%).
Effects of Allicin on Livestock Production The experiment showed that 50 mg, 67 mg, 84 mg, and 100 mg of allicin were added to each kg of layer diets compared to those fed without added allicin. The egg production rate increased by 2.73%, 5.95%, 11.10%, and 7.83%, respectively, with significant differences. Tests on dairy cows have shown that allicin can produce dense natural aromas for dairy cow concentrates, and has a strong attractant effect on dairy cows. Statistics show that the daily milk yield per cow can be increased by 2.28 kilograms, the feed intake for roughage can be reduced by 0.08 kilograms per day, and the daily income can be increased by 6 yuan to 8 yuan. In trials of lactating sows, allicin has been shown to increase pig feed intake. Tests on piglets weaned for 15 days to 28 days showed that pigs fed diets supplemented with 100 mg/kg allicin increased the daily gains of piglets and decreased the feed-to-meat ratios, which was different from those of piglets fed diets without allicin. Significant.
The effect of allicin in fish production experiments showed that allicin has a strong attracting effect. Tilapia fed with 500 mg/kg of allicin for 45 days increased the feed remuneration by 11%. With an increase of 12%, the survival rate increased by 2% to 5%, and the weight gain rate also increased. Using allicin has a good lure effect on carp, grass carp, carp, etc. The dried garlic roots were ground, minced into powder with a meat grinder, and heated and distilled to obtain a mixture of oil and water. After separation, the obtained garlic oil was fed to grass carp by 0.008% of bait weight to increase the survival rate. Above 15%, tilapia feeding increased by 10% to 15%.
