1. It is advisable to build a sheep house with a land area of ​​1 to 2 square meters per sheep, which is suitable for dry, ventilated, well-watered and clean water sources, convenient traffic and telecommunications, adequate feed and sunlight, and convenient management, or be reconstructed by using vacant land. Set up a sheep bed, a grass rack, a feeding trough and an activity site and a septic tank to create a safe and comfortable environment.
Second, grouped rearing in accordance with the male and female, size, strength and time to group feeding, reduce the sheep's stress on the transfer group, is conducive to different levels of sheep according to different nutritional requirements of the situation to deploy feed, short-term intensity fattening, early Listing, increase efficiency. Before afloatation, albinoimidazole was used to completely repel insects, and the lambs were injected with four-joint vaccine (goat epidemic disease, sheep lice, sheep enterotoxemia, lamb dysentery) and sheep pox vaccine. The pens, feeders, and the surrounding environment should be disinfected with 2% formalin or 2% sodium hydroxide solution. The fattening period is about 80 days.
Third, to strengthen the management of the lamb began fattening, there should be a pre-feeding period: only 3 days of feeding hay, 4 to 6 days of hay diet, while adding a diet, 7 to 10 days can be supplied with diet, fine The crude material ratio was 36:64, the protein content was 12.9%, the digestion energy was 10.47 MJ, the calcium content was 0.78%, and the phosphorus content was 0.24%. During the pre-feeding period, feed 2 times a day. The amount of each feed should be within 45 minutes. Diligently inspect, observe the sheep's feeding activity, mental status and sensitive response to the noise, and find the problem in time to take appropriate measures to deal with it. After the pre-feeding period is over, it enters the formal fattening period. Different diets should be used according to the fattening plan and growth requirements.
For feeding and management, lambs were fed for 10 to 14 days in advance and then switched to silage-fattening diets or diets. The daily intake of lambs should not be less than 2 kilograms per day, otherwise it will not reach the expected daily weight gain. Clean the manger and feces every day, and regularly disinfect the sheep house and surrounding environment with formalin or sodium hydroxide solution.
