Rational application of allicin feed additive

Allicin can improve the growth environment of livestock and poultry. The volatile sulfur compounds in allicin can not only emit a special smell of garlic and drive away the bite of mosquitoes and flies on feed or feces, but also be transformed into allicin under the action of enzymes in livestock and poultry, which can prevent the reproduction and growth of mosquitoes and flies in feces and improve the surrounding environment.

Allicin has disease-resistant effect on livestock and poultry. Allicin can effectively kill Shigella, Pasteurella, Salmonella enteritis, Pseudomonas aeruginosa and other pathogenic bacteria, and can enhance resistance to viral diseases. replace some antibiotics in livestock and poultry diet and promote growth and other functions, compared with antibiotics, low price, no drug residue, can improve the flavor of livestock and poultry products, improve meat quality. In livestock and poultry production, the research on the application and development of allicin instead of antibiotics is an important prerequisite and guarantee to ensure the healthy growth of livestock and poultry, the production of pollution-free animal products, and the efficient and sustainable development of breeding industry, so as to effectively improve economic benefits.

Direct application of garlic products

In the main garlic producing areas, it is more economical to use fresh garlic directly in feed. In general, fresh garlic is mixed with corn, crushed and used directly, which can effectively use the active ingredients in garlic, and the general dosage is 1%-2%. Garlic can also be dried into dry powder, and then added to the feed, the general dosage is about 0.5%.

Application of allicin preparation

The effective ingredient of allicin is chemically synthesized, and then a certain effective content of commercial allicin is made. easy to use, less dosage, is the most common way, the commonly used effective content of commercial allicin is 15% to 25%. When selecting, we should pay attention to its effective content, especially the effective content of diallyl trisulfide in garlic. Generally, the content of diallyl trisulfide in allicin should be more than 60%. Allicin is a volatile substance and is not resistant to pressure and high temperature. some allicin is treated by special techniques such as coating, so that allicin can withstand high temperature and maintain garlic for a long time, so it is more suitable for products that need to be granulated at high temperature. therefore, it should be selected reasonably according to the actual situation.

Use dose

If the dosage of garlic is too small, the effect is not obvious; if the dosage is too large, in addition to waste, the effect may also be counterproductive. The dosage should be determined reasonably according to the species of animals and the characteristics of different growth stages, combined with the effective content of allicin, so as to maximize the effect of allicin and save production cost. In general, the use of 50 ~ 100 grams of allicin per ton of livestock and poultry feed has a better effect. In the case of the use of fish meal, cottonseed meal and other raw materials, as well as the application of aroma agents and antioxidants, the dosage should be increased appropriately.

Application according to the growth stage

Although allicin can be used in various periods of animals, but in the period of rearing and weaning, as well as some animals in poor health, because their immunity is low and their resistance to disease is not strong, it is best to use some other additives to expand the antibacterial spectrum, enhance antibacterial power, and improve the effect in feed. Allicin has no incompatibility taboos, can be used with antibiotics and other additives, generally will not produce antagonistic effect.

Application effect of allicin in Animal production

The experiment showed that the laying rate of laying hens fed with 50 mg, 67 mg, 84 mg and 100 mg allicin per kilogram diet increased by 2.73%, 5.95%, 11.10% and 7.83%, respectively, compared with those fed with non-allicin fodder. the difference was significant. The experiment on dairy cows showed that allicin could produce a strong natural flavor in cow concentrate and had a strong food-inducing effect on dairy cows. Statistics show that the daily milk yield of each cow can be increased by 2.28kg, the feed intake of roughage can be reduced by 0.08kg / day, and the daily income can be increased by 6 ~ 8 yuan. In the experiment of lactating sows, it was found that allicin could increase the feed intake of pigs. The experiment on weaned piglets from 15 days to 28 days showed that the daily gain of piglets increased with the addition of 100 mg / kg allicin. The ratio of feed to meat decreased, which was significantly different from that of piglets fed without allicin feed.
