Selecting good varieties and carrying out crossbreeding Good sheep breeds have large size, fast growth, high reproduction rate, strong adaptability, good meat quality, and high efficiency. At present, there are mainly Boer goats, Sha Neng goats and Huang Huai goats. Most of the goats raised by farmers nowadays are dominated by local breeds. Their individuality is small, their growth is slow, and their slaughter rate is low, so the benefit is not high. In order to reverse this situation, Boer goats and Sha Neng goats should be introduced for crossbreeding. For example, a cross between a Boer goat and a local goat, which is nearly 10 kilograms heavier than a local goat at 6 months of age, can significantly increase the benefits. Scale should be appropriate The scale of family raising of sheep should be measured by force. It can be determined according to the number of cultivated land, the size of pasture, the amount of forage and feed, the labor force and the amount of funds invested. Generally, the scale of professional breeding households is 15 to 25 breeding ewes. Change feeding habits The remixing group grazing is a single group grazing to the lambs, single-group grazing is performed according to physiological characteristics and living characteristics, the extensive management is carefully managed, and the early cultivation is enhanced so that the lambs eat good milk, early weaning, early grazing, and early feeding. Speed ​​up its growth and development. Combining grazing and supplementary feeding in winter and spring withered grasses, it is difficult for sheep to satisfy their nutritional needs by grazing alone. Therefore, half-day grazing and half-day supplementary feeding are conducted in winter and spring, which can not only avoid the exhaustion of the sheep, but also achieve The purpose of security. Lambs are born in winter to raise lambs in winter, and lambs are born in winter. Lambs have a long growth period of 10 to 11 months. They are very beneficial to the slaughter of autumn breeding, which can avoid the wintering of sheep and save manpower and material resources. Sheep turnover, improve economic efficiency. Precise management First of all, we must do a good job of seasonal grazing, autumn weather is cool, the nutritional value of paraquat seeds is high, is the golden season of grazing, then we must try to grazing more, let the sheep eat more grass; winter cold weather, grazing as little as possible, moderate exercise You can add high quality hay and fine ingredients; the spring weather is cold and changeable, let the sheep run less and eat more; in the summer, the weather is hot and the mosquitoes and flies are numerous. Grasping as soon as possible should be done as much as possible. Second, make full use of Qingjing feed for supplementation, especially lambs, pregnant ewes, and rams. Grazing alone can not meet its nutritional needs, so be sure to add concentrate and forage, with particular attention to the supply of protein, minerals, and vitamins. Third, pay attention to providing clean drinking water and improve environmental hygiene. Clean the sheep house every day and clean the feed trough and sink to ensure that the sheep house is cool in winter and cool in summer. Regularly deworming In the rearing process, sheep are highly susceptible to both parasites in the body and inside, resulting in slow growth of the sheep, low resistance, and severe death. Therefore, the sheep farmer should carry out deworming and medicinal bathing each year according to the parasite prevalence. Usually the first insect repellent in the spring, and more with levamisole or insect nemesis, etc. drive nematodes, every 5 to 7 days, and then necrophagous nematodes 1 times, and then again in autumn. The medicinal bath is conducted once a year in spring and autumn, and the weather is selected to be warm and sunny. The water temperature is 35° C., and 0.5 to 2% of trichlorfon is used for adding sulfur for 1 to 2 minutes. Disease prevention and treatment Lamb dysentery, streptococcal disease, brucellosis, No. 5 disease, infectious pyrematitis, etc., are serious diseases that are harmful to sheep. Vaccination and comprehensive prevention and control work should be done well, and strict immunization should be established and implemented. program.
