First, the "two-stage" sheep breeding law division. From May 16th to November 15th, it was designated as summer and autumn grazing period; from November 16th to May 15th, the winter and spring feeding period was designated.
Second, the summer and autumn grazing management points. In summer, the “starry grazing†method was adopted, that is, early morning return early in the morning, evening return late afternoon, and rest at noon. Do a good job of "hanging the sheep." After the herd is harvested, the flock is rushed to the open or shaded areas, and it is only after the heat is released that it cools into the house or stays open overnight. Do not grazing in low-lying areas to prevent parasitic diseases. Gradually fall and grazing all day long in the fall. After the autumnal period, the grasshoppers will be used to make full use of the scattered grain, fallen leaves, wild grass seeds, and regenerated fresh grass grazing. From the end of August to the beginning of September, the lambs can be weaned at 4-5 months of age, and in the early October, cold lambs or fresh sperms can be used. In mid-l0. Use "Bug-star" to drive out the parasites in the body. In late October, the sheep were subjected to "three sheep vaccines" (goat epidemic, sheep enterocytosis, and chopped sheep) injections. Sheep house maintenance was carried out in early November. Each sheep covers an area of ​​1 square meter. Peripheral playgrounds, 2-3 times the area of ​​sheepfolds. A feeding trough, a grass trough and a salt replenishing trough are set on the sports ground. Rehabilitate the flock in early November and eliminate the old, weak, sick, stump sheep and infertile sheep. At the same time, provide enough forage. Sheep wood, wild hay, various crop stalks, peanut pods, sweet potato vines, pastures, etc. are good feeds 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 made into silage or semi-dry storage, ammoniation, micro-storage feeds. In the middle of November, selenium injection was performed. The drug was sodium selenite vitamin E.
Third, the winter and spring feeding period management points. Do a good job in the mating of lambs in late spring. From the beginning of winter, the "curtain" under the ram's belly is removed, and the snow breeds. Strengthen the breeding and management of rams. During the non-matching season, feed 1.5-2.5 kg of high-quality hay or peanut meal, beans, etc., and 1-1.5 kg of succulent feed such as carrots and radishes. Mix the concentrate (corn 84%, soybean meal 15%), and various vitamins. 1%) 0.5-0.7 kg, 10 grams of bone meal, 10-15 grams of salt. Feeding rations from the 1-1.5 months prior to breeding. Feed 1 to 1.5 kilograms of mixed concentrate (corn 74%, soybean meal 25%, multi-vitamin 1%) every day. Let hay be eaten, carrots, big radish 1-1.5 kilograms, eggs 2-6 pieces, bone meal 10 grams 10-15 grams of salt. Ewes were given short-term excellent feeding 20 days before mating, and 0.2 kg of mixed concentrate and 0.5 kg of green feed were fed daily. In the pre-pregnancy period, 0.15 kg of mixed concentrate (84% of corn, 15% of soybean meal, 1% of multi-vitamin) is fed daily. During the second and third trimesters of pregnancy, it is necessary to prevent crushing and crushing and prevent fecal leakage. Feed 0.3 kg of mixed condiment (corn 74%, soybean meal 25%, multivitamin 1%) 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. The lactating ewes feed 1-1.5 kg of wild hay or straw daily, 1-1.5 kg of corn silage, and 0.2-0.3 kg of mixed concentrate. Lambs eat colostrum less than one week of age, half a month old to feed on forage, and then gradually increase the amount of concentrate to reduce breastfeeding and grazing after 1.5-2 months of age. From the end of March to the beginning of April, combing from the head to the hindquarters was slowly combed, and in early May, the sheep triple injection was performed. In the middle of May, the hair was cut and the insects were dewormed and selenium injection was performed on all the sheep. In the beginning of the summer, "Sheep Storks" were set up on wooden boards in sheep pens to prevent the sheep from getting cold and getting sick.
"Two-stage" Sheep-rearing New Technology
Liaoning Fengcheng is a key production area of ​​Liaoning Cashmere goats. In recent years, the majority of sheep-raising households have changed the method of extensive sheep raising based on grazing and supplementary feeding, and actively promoted the “two-stage†sheep-raising technique, shortened the period of grazing, and extended the period of feeding, thereby reducing the Grassland grazing intensity relieves the contradiction between forestry and animal husbandry. Each sheep raises 50-100 grams of cashmere production, increases income by 15-30 yuan, and has significant economic benefits.
