1, the benefits of tail off. (1) During the grazing period, the sheep that haven't been cut off during the grazing period eat grass, and the excrement is thin. The tail swings left and right, which easily leads to contamination of the hindquarters and middle torso hair and reduces the commodity value of wool. In winter, excrement freezes and freezes, damaging the tail. (2) The tail is easily punctured by shrubs and pupa pupa when the sheep is not grazing. (3) The tailed sheep is beautiful, neat and clean. (4) Facilitate breeding and artificial insemination. 2, the timing of the tail: (1) should be 7-14 days after the birth of the lamb, such as weak constitution, the weather is too cold, can be postponed for a few days, the sooner the better the lamb as soon as possible. (2) Sheep without tails can be carried out anytime, anywhere. 3, tail off method. Use a flexible rubber band, such as a bicycle inner tube, to cut the apron with a diameter of 1 cm. In the middle of the third and fourth tail vertebrae, push the skin to the upper end by hand, and then use a rubber ring to tighten it. After 8-10 days of lambs and 25-30 days of age, the tails will gradually shrink and naturally fall off (do not cut them to prevent tetanus). This method is simple and easy to do, does not bleed, heal quickly, and has good results.
