Luxi Little Tail Han sheep is hailed as the “Chinese National Treasure†and “the Pearl of the Worldâ€. It has characteristics of strong fertility, high physique, rapid growth and development, and strong adaptability. There have been lambs with a body weight of 55 kg. Taking advantage of these characteristics, scientific breeding will have a good effect on the three levels. First choice pure breed In order to achieve the purity of choice for Small Tail Han sheep, the following characteristics must be mastered at the time of introduction: First, form standards: 1. The ram has a large head, a thick neck, and a pair of large spiral horns on its head. The ewes have small heads, fine necks, and two small horns or no horns on their heads. 2. The limbs are high-spirited, correct, and slender in body and cylindrical. 3. The tail is hypertrophic and has a round fan shape. The tip of the tail is turned over to the hocks. Second, the characteristics of hair type: 1. Attack skin type. This type accounts for about 55%-90% of the group composition. It is characterized by clear hair strands, obvious flower bends and high lambing rate. 2. Fine hair type. About 10% to 14% of the group composition is characterized by capillary and dense, smaller flower bends, and lower lambing rate. 3. Coarse type. Less than 10% of the group composition is characterized by thick hair, large flowers, and middle lambing rate. Third, reproductive characteristics: purebred Small Tail Han estrus to the spring and autumn is more concentrated, the initial allocation of rams for 8 months, ewes 6-7 months, estrus cycle 16-18 days, estrus sustained 24-36 hours, during pregnancy The average is about 150 days. The average number of litters born is 2.5, and the average initial weight of lambs is 3.6 kg. The weaning survival rate is over 90%. The second pass raises the survival rate of lambs The key to raising the economic benefits of raising small-tailed Han sheep is to increase the survival rate of lambs. The main measures are: First, the good ewes are pregnant. General ewes 6 months of age can be estrus mating, estrus sheep showed redness and congestion of the vulva, there is oozing from the vulva outflow and cross reflection phenomenon, this time for the best breeding "breathing", seize the opportunity to breed. The virgin sheep had obvious estrus, and many refused to climb. When they refused, they had to stand on Baoding. Once not enough, you can take multiple seasons to breed. During pregnancy, it is necessary to strengthen management, mainly feeding, grazing supplements, or complete feeding. Feed high quality feeds to ensure nutritional needs. Mountains should avoid grazing on steep slopes to prevent miscarriage. Winter ewes should drink warm water for pregnant ewes. Do not drink iced water. Second, the lambs and lactation off: After giving birth, let the ewes feed on the lamb's fetal water first, when the weather is cold, it is necessary to make it warm. For newly-born lambs, the confinement person must put his index finger into the lamb's mouth to allow him to suck it and allow the lamb to eat colostrum in time. The colostrum is rich in antibodies, magnesium and other substances, which can enhance the lamb's disease. The immune system promotes the discharge of meconium. Manual feeding is the best way to make up when the ewes are one-child-big and the teats and milk are relatively inadequate. Fresh milk, milk powder, millet soup, etc. will be fed into the bottle. Third, the lamb disease: Common diseases, iron deficiency, lack of selenium nutrition diarrhea and bacterial diarrhea. In this regard, under the guidance of veterinarians to apply LH iron preparations and trace elements added selenium, bacillary dysentery must use drugs for timely treatment.
