Lambs were slaughtered in three months and slaughtered. Feeding concentrates was supplemented by grazing. 40-day-old weaned, after 50 to 60 days of fattening after finishing slaughter, generally up to 30 to 40 kilograms, fresh and delicious lamb, economic efficiency has increased substantially. The technology is: Lamb breaking: Lambs can be tailed from 3 to 20 days old, but it is suitable for 3 to 10 days old. General choices are made on sunny days. The method is: using a rubber band with better elasticity, put it between the 2nd to 3rd caudal vertebrae of the lamb so that the lower part of the lamb's tail is not nutrition and shrinks. After 10 days, it falls off on its own. Can also be used to tie the tail of the string, cut off the blood circulation, and then use a sharp knife cut off at the end of 4 to 5 cm, with a good gauze bandage, the same afternoon, the string can be untied, a week or more. By severing the tail can accelerate the growth of mutton sheep, improve the meat quality and reduce the odor. Ram castration: It can be done at the same time as the tail. The testicles of male lambs within 8 days of age are squeezed into the scrotum, tightly tangled with the rubber band in the spermatic cord and the scrotum. After 20 to 30 days, the scrotum and testicles will dry naturally and fall off. Feeding in the pens: implement pens, feed feed, proper grazing. First of all, the deworming was carried out with an oral repellent of 5 to 10 mg per kilogram of body weight. The injection was injected subcutaneously at 5 to 10 mg per kilogram of body weight. The second is to formulate fine feed, the formula is: corn 54%, bean cake 15%, grass powder 22%, lime powder 1.5%, wheat bran 7%, salt 0.5%, mixed feed, 3 times a day, lamb 15 to 20 kilograms of body weight, 0.75 kilograms per day, with the increase of body weight, feed gradually increased, and appropriate grazing or forage. Note: After feeding the concentrate, let the sheep drink water. The lamb has just started to feed and sometimes falls out of the mouth. As the age increases, this phenomenon will gradually disappear. Under normal circumstances, the lamb's excrement is lumpy, yellow, and the weather may change or rainy days, and diarrhea may occur. Pay attention to heatstroke prevention in summer, moisture protection in autumn, cold protection in winter and spring, and always pay attention to various diseases. When the sheep only have the phenomenon of housing, increase the amount of salt and lime powder in the feed. China Agricultural Network Editor
