Pay attention to the selection and selection of the cultivar that produces 2 or 2 annual fertility, such as Han sheep, or chooses the first-born to produce double lambs and 2 to 5 fetal lambs to breed. Or the selection of multiple ewes based on family status is a reliable way to increase the reproductive survival rate of newly born ewes. The breeding yield of the first-born ewes of the local improved species is 20%-25% higher than that of the newly-born ewes of the improved varieties.
Note that age-appropriate, age-matched sheep are generally sexually mature from 7 months to 8 months of age, but sexual maturation does not mean that sheep are suitable for the start of breeding time. Because the sheep did not reach full development in the early stages of sexual maturity, if mating at this time, it will affect itself and the development of the fetus. The first-born ewes should generally start breeding at the age of one and a half years.
There is a positive correlation between body weight and ovulation rate of first-maturity ewes. When the body weight is increased by 1 kilogram, the ovulation rate can be increased by about 2%. The appropriate breeding weight of ewe differs depending on the species. The weight of Han sheep is generally about 40 kilograms. It is appropriate.
Note that nutrient nutrition is the material basis for maintaining the life and reproduction of the sheep. To improve fertility, it is necessary to ensure the nutrient supply of male and female ewes during the mating season, and do well in feeding and management such as grazing and feeding. Poultry and ewes with poor body condition can increase the amount of protein feeds such as bean cakes, so that the ewes can have more ovulation. The breeding rams can be fed with 1 or 2 eggs a day to produce a large amount of high-quality semen and raise the conception rate.
Pay attention to the use of male ram Rams fertility level, directly affecting the ewes' abortions and lambs produced by the quality. In terms of the ram's genitalia, the scrotum circumference should be more than 36cm, and the testis weight should be 250g~300g. At the same time, sperm viability is required to be above 0.85 and the density is above 75 million. If more than 3 primiparous ewes are repeatedly incompatible with the same ram when estrus is normal, the rams should be eliminated in time.
Attention to the use of artificial insemination technology artificial insemination has improved the utilization rate of high-quality rams, reduced the amount of rams, reduced feeding costs, and reduced the spread of diseases such as skin diseases and the reproductive system. It is not subject to geographical restrictions, timely breeding, easy to grasp, and giving birth. High rates, many litters and other advantages. Therefore, we should vigorously promote the artificial insemination technology of ewe. As artificial insemination technology is a technology with high technical content and strict requirements, the inseminator should have the spirit of love, respect, dedication and hard work. At the same time, it must have excellent technology and operate in strict accordance with the procedures. The temperature of the insemination chamber is preferably 18°C~28°C. The equipment used for insemination must be strictly sterilized before it can be used. The treatment of semen should be careful, and the vitality and density of microscopic examination must be up to the standard before insemination.
Pay attention to the cultivation of lambs
1. Cultivation before birth (from ewe mating to birth before birth): The biological value of the protein in the feed for ewe needs to be high, vitamins must be rich, and full price nutrition is needed to ensure normal development and perfection of various tissues and organs. . In the second trimester of pregnancy, the ewes must be supplemented with soya bean cake, corn, wheat bran and other fine materials, high-quality green grass or hay (preferably leguminous), bone meal and other mineral feeds to increase the weight of ewes by 10% to 15%. Due to hereditary decisions, the ewes are large in size and the lambs are usually born with a large weight, and they are well developed and robust.
2. Incubation after birth (from the birth of the lamb to the weaning): The ewes need more artificial labor. After the birth, the umbilical cord is manually broken. At the same time, the ewes of the ewes are rubbed on the lambs in order to allow the ewes to have their own lambs. The lambs can be divided into three phases, front, middle, and back, depending on the feeding and management of the lambs.
Pre-lactation (from birth to 20 days to 25 days). At this stage, we must increase the quantity and quality of breast milk as a basic measure of cultivation work. In addition to properly increasing the concentrate of ewes, we must increase the amount of succulent feeds such as carrots, squash and leafy vegetables to promote lactation. force. Under normal circumstances, the lamb needs 500g of breast milk for each 100g of weight gain. This phase mainly focuses on three things: First, it is timely to eat colostrum. Lambs should eat colostrum within 1 hour after birth. The second is to make up as much as possible in advance. Lambs should normally start feeding after about 10 days of age in order to train their ability to feed roughage, but also increase nutrition to meet the needs of the growth and development of lambs. Training method: In the spacious and bright sheep house, use the column-type split sheep fence (the distance between the fence column is only suitable for the lambs to enter and exit), separate the appropriate area of ​​the lamb supplemental feeding fence, put the feeding trough, and evenly in the trough Sprinkle some fried yellow material, chopped carrots, grass, or hay. The hay can also be tied up with straw bales (it is advisable for the lamb to be eaten by the lamb). The third is to exercise as early as possible to enhance the body of the lamb.
Mid-lactation (grazing from mother to child at 20 days to 25 days). The lamb's feed in this period should be diversified, and less feed should be added. Breastfeeding regularly, usually 3 times to 4 times a day, once in the morning and evening breastfeeding. Always pay attention to the growth and development of the lamb so that the entire population develops evenly.
Late lactation (grazing from mother to child to weaning at about 4 months of age). Places where conditions permit, lambs can be grouped individually to grazing where the quality of the forage is good and closer to the sheep's house. The distance between the ewes and the lambs is not suitable for the sound of mutual crows. Mother and son gather in the night.
While grasping the three phases of feeding and management of lambs, we must pay attention to the disease prevention and control of lambs, among which the prevention and control of lamb fleas is particularly important, and the ratio of sulfadiazine to enemy bacteria can be 1:5, lambs per kilogram body weight 25 mg. Once a day, use 2 times, the effect is good.
