How to maintain a good and scientific ram
Rams are used for breeding, and their fertility is productivity. The quality of semen provided by a ram is directly related to the lamb's lambing rate and the lamb's production performance. In order to improve the economic efficiency of raising sheep, we must do a good job in breeding and management of breeding rams. 1. Carefully selected rams should choose those rams whose appearances are in line with the characteristics of the species, with strong spirits, liveliness, and robust rams as species, special attention should be paid to observing external genital organs, eliminating single testes and cryptorchid rams. The pedigree of the selected ram must also be identified. Individuals with ancestral hereditary diseases and inbreeding should not be kept for seed use. They should be preserved from twin lambs and lambs. To adopt the principle of keeping multiple selections, two screenings are generally conducted. The first screening at 3 months of weaning is performed. The individuals with good physical development are selected. At the age of 6 months, the average daily weight gain is faster and the second sex is selected. Significant individuals. Second, scientific breeding ram 1, nutrition full price. Rams must have more than half of the sensation, and their diet should be reasonable, especially the supply of protein, minerals and vitamins. Insufficient supply of protein will delay the development of ram's genitals and decrease spermatogenesis. Therefore, feed should contain adequate amounts of protein. Commonly used protein feeds include soybean cakes, peanut cakes, legume grasses, fishmeal, etc., and should be supplied during the breeding period. Animal protein feed. The lack of minerals will result in incomplete sperm development and decreased vitality. It is necessary to add shell flour, calcium phosphate and other mineral feeds in the feed. The ratio of calcium to phosphorus is controlled at 1.5-2:1. Lack of vitamins will reduce the libido of the sire, increase the green and juicy feed to increase the vitamin content, and mix the multi-dimensional multi-dimensional ingredients in the concentrate during the subtilis period. 2, strengthen sports. Long-term lack of exercise in the ram, the body is not strong, easy to obesity, reduce breeding ability. The rams should be given adequate outdoor exercise and light, an average of 4-6 hours a day. In the summer, enough water should be provided after exercise. 3, single circle feeding. The rams should be raised in a single circle and the area of ​​the pens is 2 square meters. In this way, the number of matings caused by male and female polyculture can be prevented, and the ram's reflective decline can be prevented, and rams can fight each other and consume physical strength. In addition, sheep should be brushed every day and regular work such as shearing, hoof repair, medicine bath, and epidemic prevention should be conducted to ensure that the ram is healthy and disease-free. Third, the rational use of species rams 1, grasp the breeding time. The use of rams will affect their own development too early, and the use of rams will increase the cost of raising them too late. It is advisable to start breeding at the stage between sexual maturity and maturity. The rams are sexually mature for 6-10 months, and the initial age is 12-15 months. There will be differences between different breeds. The ram's useful life is generally 6-8 years. 2, control the number of breeding. The number of rams mating is too many, seriously affecting semen quality and useful life. Therefore, we must strictly control the number of mating rams, 1-2 times a day (2 intervals of 8 hours), each mating 5-6 days, rest 1 day is appropriate. The number of breedings may be increased in the fall, but not more than 3 times per day. 3, using artificial insemination technology. To increase the utilization of rams and reduce the spread of reproductive tract diseases, we should adopt artificial insemination techniques. The ram has a strong ability to produce sperm. Each time it shoots two to three billion sperm, the natural mating of each ram is 30 to 50 per year. If artificial insemination is used, it can be increased to 700 to 1,000, greatly improving the public Sheep breeding performance.
