Pig hair is long, stringed and difficult to shave.

Ladies and gentlemen, let's talk about, now farmers use our concentrated feed, pig hair is long, strands are beaten, there are people who kill pigs themselves, the reaction hair is not easy to shave, and the piglet feed he uses throughout the process, I don't understand why on earth. Is it the reason for the arsine preparation? is there any reason for choline? our formula is 5 kg / ton. It has something to do with whether the addition is too large. Hehe, it should be caused by environment and heredity.
