The fast fattening of the mutton sheep allows lambs to be slaughtered for two months, weighing 15-20 kilograms and a survival rate of over 98%. The fattening soup has the following points:
First, choose lamb fattening. From the lamb population, lambs with large individuals, well-developed animals, high feeding power, and no disease were selected to form a fattening group after weaning. It is better to choose the male lamb because the male lamb grows faster and does not reach sexual maturity at this time.
Second, the lamb supplement. Cereal feed can be used with appropriate amount of soybean cake, and mixed concentrates can also be used, such as corn 45%, wheat bran 22%, soybean meal 30%, salt 1%, and fishmeal 2%. Lamb's concentrate feed increases with the age of the month. At the age of 20-30 days, the amount of lambs per lamb is 50-70 grams; at the age of 1-2 months, it is 100-150 grams; at the age of 2-3 months, it is 200 grams and it is fed twice a day.
Third, timely termination of the tail. Lamb tailing can accelerate the growth of mutton sheep, improve meat quality, and reduce odor. Lambs can be tailed at 2-21 days of age, but are most suitable for 2-7 days of age. The tail-breaking time is best performed on a sunny day. Method: 1 rubber band broken tail. Use rubber elastics with better elasticity and fit between the 2-3 caudal vertebrae of the lamb so that the lower part of the tail is not nutrition and shrinks. After 10 days, it can fall off on its own. 2 fast knife broken tail. First, tie the tail with a string, cut off the circulation of blood, and then cut off with a sharp knife at 4-5 cm from the tail and wrap it with gauze. In the afternoon of the same day, the tether can be untied and healed after 5-7 days.
Fourth, castration promoted. Chlamydial castration is generally performed at the same time as the tailing, and the rubber band method and surgical method can be used. Commonly used is the rubber band method. The testicles of a male lamb within 7 days are squeezed into the scrotum. The spermatic cord is tightly tangled with the scrotum with a rubber band. After 20-30 days, the scrotum and the plug pill will dry naturally and fall off. .
Fifth, timely disinfection. In the feeding and management of mutton sheep, there must always be sufficient and clean drinking water supply. The interior should be kept well ventilated, the ground should be dry, there should be bedding, and the feed should not be contaminated. Clean and disinfect sheep pens, sheep houses, chutes, and sinks; lambs, grasses, forages, utensils, etc. should be grounded in the sun, and work clothes and medical equipment should be boiled and sterilized.
Sixth, prevent diseases. According to the local epidemic characteristics of sheep disease, adhere to the principle of “prevention and treatment†and systematically carry out drug prevention and immunization against herds to prevent the occurrence of infectious diseases and parasitic diseases.
7. Sled out in time. The fattening sheep can be slaughtered in accordance with the market conditions in a timely manner, which can shorten the fattening cycle of mutton sheep and increase the economic benefits of raising sheep.
