Application of feed additive "garlic"
Allicin is the general name of the main biological active ingredients in garlic. It has a long history of garlic in China. It is a broad-spectrum antibacterial agent with anti-inflammatory, blood pressure lowering, blood lipid lowering, platelet aggregation inhibition, cancer prevention and anti-virus, etc. A variety of biological functions, which are used for animal husbandry and aquaculture feed additives are researched and developed according to the development of rural aquaculture, and have promotional value. The author will now introduce the application technology as follows for the reader's reference.
(1) The functional role of allicin
1, bactericidal effect. Allicin has good inhibition and killing effect on Escherichia coli, Salmonella, Pseudomonas aeruginosa, etc., which cause diseases of livestock and aquatic animals, especially for cow and pig enteritis, grass rot, red skin disease and fish The fulminant infectious diseases are particularly effective, and it is an effective way for the majority of rural areas to save investment and develop aquaculture for disease prevention and control.
2. Improve the palatability of the feed. In recent years, in order to reduce the cost of feed, many farmers often use some poorly-suited feeds or some long-acting drugs in compound feeds, which cause the feed intake of farmed animals to decline or refuse to eat, resulting in slow and thin animals. By adding allicin, the palatability of the feed can be significantly improved and the feed intake can be improved.
Allicin attracts the animal's consumption of the feed through the smell of garlic, which causes appetite and thus increases feed intake. Most animals, especially fish, like the smell of allicin.
3. Improve production performance. Allicin can not only increase the feed intake of animals, but also 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 improve the feed of livestock and fish. Digestion and utilization, thereby improving production performance and reducing feed costs.
Allicin can be turned into garlic vinegar under the action of enzymes, and it can be discharged in the form of excrement, which can prevent the breeding and growth of pests in the breeding and improve the environment of the pens and ponds.
(B) the use of allicin and the amount of additives
Add fresh garlic. It is often made of mashed, chopped or ground meat with a meat grinder and then added to the feed. Or mix fresh garlic with the feed ingredients and smash them. Fresh garlic is added in the feed from 1% to 10%, and is added according to the size of the livestock. Generally, it is divided into three types: small, medium and large (ie, 1%-2%, 2%-4% or 5). %-6%, 8%-10% larger).
(3) Application effect of allicin in animal husbandry production
The author tested in the foreign-invested laying hen farm in our county, adding 50, 67, 84, 100 mg of allicin per kilogram of ration to the laying hens compared with the laying hens fed with no added garlicin. The increase was 2.73%, 5.95%, 11.10%, and 7.83%, and the difference was significant. The test on dairy cows shows that allicin can produce a strong natural flavor of dairy cow concentrate and has a strong attracting effect on dairy cows. Statistics show that the daily milk yield per cow can be increased by 2.28 kg, and the feed intake of roughage can be reduced by 0.08. Kilograms/day, increase income by 6-8 yuan per day. In the trial of lactating sows, it was found that allicin increased the feed intake of pigs. The piglet test for weaning for 15-28 days showed that the daily weight gain of the piglets was increased and the feed-to-meat ratio was lower than that of the piglets fed with garlicin, and the difference was significant compared with the piglets fed without the garlicin feed. With.
(4) The effect of allicin in fish production
In the Yanxia Reservoir of Tongshan County, Hubei Province, tilapia was fed with 500 mg/kg for 500 days. It was found that allicin had a strong attracting effect, the feed compensation increased by 11%, and the comprehensive evaluation of feed biology was improved. 12%, the survival rate increased by 2%-5%, and the weight gain rate also increased. The use of allicin in Rujiatian Reservoir of Tongshan County has a good attracting effect on carp, grass carp and carp. The Hubei Enan Feed Additive Technology Development Service Center uses dried rooted garlic heads. Grinding into a powder with a meat grinder, heating and steaming, to obtain a mixture of oil and water, after separation, the obtained garlic oil is added to the grass fish according to the weight of the bait of 0.008%, the survival rate is increased by more than 15%, feeding Luo Fei Fish weight gain increased by 10%-15%.
(5) Application prospects of allicin
According to the above practice, allicin can significantly improve production performance, reduce morbidity, reduce mortality, and increase breeding efficiency. It can partially replace antibiotics to reduce the resistance of microbes, and has a beneficial effect on the health of livestock and fish. Adding allicin to feed can be a way to solve the problem of antibiotics.
