What are the processing methods for garlic feed additives?

I. The role of garlic in livestock and poultry production

1. Adding peeled and chopped raw garlic to broiler chicken feed at a ratio of 3%-5% can not only increase the appetite of broiler chickens, improve chicken meat quality, and make the chicken meat aroma richer, but also significantly increase the daily weight gain of broilers. Adding 0.2% dried garlic powder to chick feed can increase the survival rate of chicks by 5.8%-15.6%; adding 2% garlic premix to the diet of laying hens can increase the egg production rate by 98%; adding 2% garlic premix to the diet of meat-type and breeding chickens can increase the egg production rate by 5.6%; using allicin (extracted and processed from garlic), organic germanium and selenium to make an additive for feeding laying hens can not only increase the egg production rate, but also prolong the peak egg production period; after feeding breeding roosters with garlic, the weight gain efficiency of broilers can be improved.

2. Adding a small amount of garlic to pig feed is beneficial to the growth and development of pigs. Adding 3% garlic to the feed of lactating sows can increase the daily feed intake of sows by more than 2 kg; adding 2% garlic to piglets weaned for 15-25 days can increase the daily weight gain of piglets by more than 6.9%. Adding 3%-5% garlic to dairy cow feed can produce a very good feed-attracting effect on dairy cows, and the daily milk yield of each dairy cow can be increased by about 2 kg, while the daily concentrate consumption decreases by 0.8 kg. Garlic can also be used to treat diseases such as piglet white scour, bovine rumen bloat, gastric cold with refusal to eat, enteritis and diarrhea, and rumen impaction caused by weakness of the spleen and stomach.

II. Processing of garlic feed additives

1. Adding fresh garlic When the amount used is small, fresh garlic can be peeled, mashed, chopped, or made into garlic paste with a meat grinder, and then added to the feed and fully stirred for feeding; when the amount used is large, fresh garlic (without peeling) can first be mixed with the main ingredient of the feed (generally corn) according to the required amount, and then crushed. This neither affects the crushing effect of the active ingredients nor prevents the garlic from being evenly mixed in the feed. The addition amount is generally 1%-5%.

2. Adding dried garlic (residue) powder Garlic or residue (the leftover material after steam distillation to extract oil) is made into dried powder, and then directly added to the feed in proportion, or added to a carrier to make a premix and then added to the feed. The addition amount in the feed is: 0.2%-1% for chickens, and 0.5%-1.5% for pigs and cattle.

3. Adding garlic water or alcohol extract When using a water extract, evaporate the water after extraction; when using an alcohol extract, evaporate the alcohol. The former is added at 0.02% in chicken feed, and at 0.05% for pigs and cattle; the latter is added at 0.03% in chicken feed, and at 0.05%-0.1% for pigs and cattle.
