Methods of Adding Garlic to Feed and Its Effects
Methods
When adding fresh garlic in small amounts, peel the fresh garlic, mash it, chop it, or grind it into garlic paste with a meat grinder, then add it to the feed, mix thoroughly, and feed. When adding it in large amounts, first mix the fresh garlic (peeling not required) with the main ingredient of the feed (generally corn) in the required amount, then grind it. This neither affects the grinding effect on the active ingredients nor prevents the garlic from being evenly mixed into the feed. The addition ratio is 1%-5%.
Adding dried garlic (residue) powder: Make garlic (residue, that is, the leftover material after steam distillation to extract oil) into dried powder, then add it directly to the feed in proportion or add it to a carrier to make a premix and then add it to the feed. The addition ratio in chicken feed is 0.2%-1%, and the addition ratio in pig and cattle feed is 0.5%-1.5%.
Adding garlic water extract or alcohol extract: When using the water extract, evaporate off the water after extraction; when using the alcohol extract, evaporate off the alcohol. The former is added at 0.02% in chicken feed and at 0.05% in pig and cattle feed; the latter is added at 0.03% in chicken feed and at 0.05%-0.1% in pig and cattle feed. For the premix formed after a carrier absorbs garlic oil (extracted from garlic or artificially synthesized), when feeding poultry it can be added at 0.05%-0.2% of the feed, when feeding pigs and cattle it can be added at 0.1%-0.3% of the feed, and when feeding fish it can be added at 0.08%-0.2% of the feed.
Effects
Feeding chickens: Adding peeled and chopped fresh garlic at a ratio of 3%-5% to broiler feed can not only enhance the appetite of broilers and improve chicken meat quality, but also increase the daily weight gain of broilers; adding 0.2% dried garlic powder to chick feed can increase their survival rate by 5.8%-15.6%; adding 2% garlic premix to laying hen feed can increase their laying rate by 9.8%; adding 2% garlic premix to meat-type breeder feed can increase the laying rate by 5.6%. Using an additive made from allicin (refined and processed from garlic), organic germanium, and selenium to feed laying hens can not only increase the laying rate, but also prolong the peak laying period. After feeding garlic to breeding roosters, their libido becomes strong, semen quality is good, and the fertilization rate of breeding eggs is increased. Frequently feeding garlic to chickens can improve body resistance, enhance immunity, and reduce the occurrence of diseases, especially making them less susceptible to digestive system diseases. In addition, garlic can also be used to prevent and treat pullorum disease in chickens, fowl cholera, and so on.
Feeding pigs: Adding 3% garlic to the feed of lactating sows can increase their daily feed intake by more than 2 kg; adding 2% garlic to the feed of piglets weaned for 15-25 days can increase their daily weight gain by more than 6.9%. The volatile sulfur-containing compounds in allicin can give off a special garlic odor that drives away mosquitoes and insects from biting and sucking on feed or manure; allicin can also be converted into allicin-like pungent compounds in the pig body, and after being excreted in urine and entering the manure storage pit, it prevents mosquitoes and flies from reproducing in manure and urine and from larval growth, reduces disease transmission, increases the survival rate of weaned piglets, and improves the surrounding environment. In addition, allicin can also inhibit mold metabolism and kill many molds in piglet feed, including Aspergillus flavus, Aspergillus niger, Aspergillus fumigatus, and others, extending the storage period of feed. Allicin can effectively kill many pathogenic bacteria such as Shigella dysenteriae, Pasteurella, Vibrio cholerae, Salmonella typhi, Staphylococcus, Streptococcus pneumoniae, Proteus, Pseudomonas aeruginosa, Salmonella enteritidis, and others, and has functions such as enhancing resistance to viral diseases, replacing some antibiotic drugs in piglet diets, and promoting growth. Moreover, garlic is low in price, leaves no drug residues, can improve the flavor of livestock products, and improves meat quality.
Feeding dairy cows: Adding 3%-5% garlic to dairy cow feed can produce a very good feeding attraction effect, and can increase the daily milk yield of each dairy cow by about 2 kg while reducing daily concentrate consumption by 0.8 kg.
