The breeding age of sheep is generally 2-5 years old. Ewes that are oversized are susceptible to mastitis and the amount of lactation is reduced. When the age is too small, it is still in the stage of growth and development, and the amount of lactation is insufficient. According to the survey, the peasants' general mating age of the ewes is generally not controlled. The old ones are still mated until 7-8 years old. The younger hens will start breeding when they are younger than 4-5 months. This will easily result in production of weak lambs. High-quality small-tailed sheep rams and breeding ewes play a significant role in the growth quality of sheep. Therefore, the selection of high-quality small-tail sheep is the key to the success of sheep breeding. The selection and selection of breeding ewes is poor, and the breeding ewes must be selected. The old and weak ewes are resolutely eliminated. The ewes were selected from the ancestors of the ewes, themselves and their offspring. Ewes with the following conditions were selected according to their growth and development, body shape and production performance. The sheep's mental condition is better, and the eyes are plentiful. The head and ears should be straight, the ears should be large, the tail should be small, there should be no stray hair, and the fat and lean should be moderate. Look at the teeth to estimate the age, and look at the genitals, eyes, breasts, and hooves for diseases. At the same time, their body length, chest circumference and height were measured one by one according to a predetermined standard. Prevent the introduction of ewes that are older, less able to reproduce, or have disease defects, and groom them until 6-12 months before starting breeding. The physical characteristics of the ram's selection of rams are very important. As the saying goes: “The rams are good, they are good, they are ewes, and they are good.†The breeding and management of the breeding sheep breeder has a great influence on the reproduction rate. The breeding weight of the ewe before mating and the libido is strong, the mating rate and the lambing rate are high. Therefore, the usual feeding and management of ewes should be strengthened to meet the needs of various nutrients. And do a good job of short-term superior feeding before breeding, increase energy, protein and vitamins and other feed, in order to lay the foundation for improving the fetus and lambing rate. While grazing and eating green, each sheep feeds 100 grams of soybean powder daily, 200 grams of corn or barley flour, 200 grams of bran, 15 grams of salt and 15 grams of baking soda, and is mixed and fed with water, and feed for 30 days. Can quickly enhance physical fitness, promote estrus and improve conception rates.
