However, we can't believe and rely too much on the need for good feeding management to raise chickens.
You can mash garlic with skin about 0.3% or mix it directly with allicin, and mix it evenly according to the product instructions.
If the early management is good, you can mix the materials 7 days before the slaughter, and it will also have the effect of attracting food and gaining weight.
You can also use it at ordinary times. There are no compatibility taboos.
I've used allicin, and the finished product works well.
