Two-stage sheep breeding
The "two-stage" method of raising sheep will be divided into summer and autumn grazing from May 16 to November 15 each year, and winter and spring feeding period from November 16 to May 15. Summer and autumn grazing grazing management key points in summer days, we should adopt the "starry sky" type of grazing method, early morning return early in the morning, evening late evening return, rest at noon. Do a good job of "drying sheep". Do not grazing in low-lying areas to prevent parasitic diseases. Gradually fall and grazing all day long in the fall. In late August and early September, lambs can be weaned from 4 months to 5 months of age. In early October, breeding starts. In mid-October, the "insect nemesis" was used to drive off the parasites in the body. In late October, the sheep were given preventive injections of "mutant sheep triple vaccine" (goat epidemic, sheep enterocytosis, and sheep lice). Shelter maintenance was carried out in early November. Each sheep occupies an area of ​​1 square meter. The sheep pen is a playground outside the area, which is twice or three times the area of ​​the sheep pen. There are facilities such as feeding trough, straw trough and salt sink in the sports ground. . Rehabilitate the flock in early November to eliminate old, weak, sick, disabled and infertile sheep. At the same time, to provide enough forage, hay, various crop stalks, peanut pods, sweet vines, pastures, etc. are good feed for wintering. Each sheep should prepare winter forage, 200 kg of straw, 300 kg of green and succulent and silage, and 20 kg to 30 kg of concentrate. A large number of corn stalks, straw, wheat straw, etc. can be silage, semi-dry storage, ammoniation, micro-storage. A selenium injection was given in mid-November. In the winter and spring feeding period, the main points of feeding and management started from the beginning of the winter season. The curtains of the rams' bottoms were removed, and the breeding was carried out in "little snow." Strengthen the breeding management of rams. In the non-matching season, feed 1.5 kg to 2.5 kg of high-quality hay or peanut meal, 1 kg to 1.5 kg of succulent feed such as carrots and radish, and mix concentrate (corn 84%, soybean meal 15%, multivitamin 1). %) 0.5 kg to 0.7 kg, bone meal 10 grams, salt 10 grams -15 grams. One-and-a-half months before the start of breeding, they were fed a breeding period, and mixed concentrates (corn 74%, soybean meal 25%, multi-vitamin 1%) 1kg - 1.5kg were added every day and hay was allowed to feed. Carrots, large radish 1 kg to 1.5 kg, 2 eggs to 6 pieces, 10 grams of bone meal, 10 grams of salt to 15 grams. 20 days before the ewes are mated, short-term excellent feeding is conducted. 0.2 kg of mixed concentrate is fed daily and 0.5 kg of green feed is fed. In the pre-pregnancy period, 0.3 kg of mixed concentrate (corn 74%, soybean meal 25%, multi-vitamin 1%) was fed daily. After weaning, the lambs were fed 0.3 kg of mixed fines each day, and the straw feed was allowed to feed and freely drink water. Deworming and epidemic prevention were carried out with the ewes in the same period. At the beginning of April, the ewes were lambing one after another. Lactating ewes feed 1 kg to 1.5 kg of hay or straw daily, 1 kg to 1.5 kg of silage corn, and 0.2 kg to 0.3 kg of mixed concentrate. The lamb was allowed to eat enough colostrum within one week after birth and was trained to feed on forage during the first half of the year. Afterwards, the amount of concentrate was gradually increased, and the amount of feeding was gradually reduced. After one and a half months of birth, the lamb was grazing with the herd. From the end of March to the beginning of April, combing, using a combed tweezers, slowly merging from the head to the hindquarters until it is combed. In early May, an injection of triple sheep vaccine was performed. May mid-shorn shearing, while deworming. In the middle of May, selenium injections are also given to all sheep. In the beginning of summer, use sheep's nests to set up "Sheep Storks" in sheep's nests to prevent them from getting cold and getting sick.
