1, the benefits of tail off. (1) During the grazing period, sheep that haven't been cut off grazing eat grass, and the excrement is thin. The tail swings left and right, which easily leads to contamination of the hindquarters and middle trunk hair and reduces the commodity value of wool. In winter, excrement freezes and freezes, damaging the tail. (2) The tail is easily punctured by bushes and pupa pupa when the sheep are 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, if the constitution is weak, the weather is too cold, can be postponed for a few days, the sooner the better the lamb tail. (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, non-bleeding, fast healing, and good results. China Agricultural Network Editor
