Garlic feed additive processing method
Garlic has long been recognized for its beneficial effects on animal health and productivity when used as a feed additive. Its natural compounds, such as allicin, have antimicrobial, antioxidant, and immune-boosting properties that can enhance growth, improve meat quality, and increase egg production in poultry, while also supporting the overall well-being of livestock.
In broiler chickens, adding crushed or chopped raw garlic at a rate of 3-5% in their diet can significantly boost their appetite, leading to better weight gain and improved meat quality. The flavor of the chicken becomes more pronounced, which is highly desirable in the market. Additionally, including 0.2% dry garlic powder in the diet of chicks can improve survival rates by up to 15.6%. For laying hens, adding 2% garlic premix can increase egg production by as much as 98%, while for broiler breeders, it can raise egg production by around 5.6%. When combined with allicin, organic germanium, and selenium, garlic additives not only enhance egg production but also extend the peak laying period.
For pigs, even small amounts of garlic can promote better growth and development. Adding 3% garlic to the diets of lactating sows increases their daily feed intake by over 2 kg. In weaned piglets aged 15-25 days, adding 2% garlic can boost daily weight gain by more than 6.9%. In dairy cows, 3-5% garlic in the feed can stimulate milk production, increasing daily yield by about 2 kg per cow while reducing the need for concentrate feed by 0.8 kg. Garlic is also effective in treating common issues like white piglet syndrome, bloat, indigestion, enteritis, and diarrhea caused by weak digestive systems.
The processing methods for garlic feed additives vary depending on the form used. When using fresh garlic in small quantities, it can be crushed, chopped, or made into a puree using a food processor before being mixed thoroughly into the feed. For larger quantities, whole unpeeled garlic can be mixed with the main feed ingredients, such as Corn, and then ground together without affecting the potency of the active compounds. This method ensures even distribution and maintains the effectiveness of the garlic.
When using garlic dry powder or residue, the garlic should first be dried—either the fresh product or the leftover material from steam distillation and oil extraction. It can then be directly added to the feed or blended with a carrier to create a premix. The recommended addition levels are generally 0.2–1% for poultry and 0.5–1.5% for pigs and cattle.
For garlic water or alcohol extracts, the liquid is typically concentrated by removing moisture or alcohol before use. These extracts can be added at lower concentrations: 0.02% for chickens and 0.05% for pigs and cattle when using water-based extracts, and 0.03% for chickens, with 0.05–0.1% for pigs and cattle when using alcohol-based extracts.
By incorporating garlic into animal feed, farmers can naturally enhance performance, reduce the need for synthetic additives, and improve the overall health and productivity of their livestock.
