The method of drawing bristles from live pigs
It is best to pull out bristles from live pigs in summer, when it is the period of changing hair and taking off mane. Five minutes before the first plucking, feed the pig some lees to expand its pores, then touch the pig with one hand while the pig is eating or lying still, and pull the bristle with the other hand to see if it is pulled off gently. If the hair root has been loosened, it shows that it is the most appropriate time to pull it out at this time. When it is known that the hair root is loose, you can comb the mane of the pig from back to front with a fine wood comb. The mane can be combed, sorted out and stored in a pre-prepared paper bag. If the hairy root is not very loose, you can first use the thumb, index finger and middle finger, hold three or five manes and pull them up, once every 1-3 days, not too much each time until you are finished. In this way, as long as the hair is plucked in time, a pig with 100kg weight can pull out bristle 1~2kg. Pulling out bristles from live pigs will not affect the normal growth and development of pigs, because of the stimulation of pulling bristles, it can not only increase the appetite of pigs, but also accelerate fat gain.
