First, select fine varieties according to local conditions and carry out hybridization and improvement. 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 is nearly 10 kg heavier than a local goat at 6 months of age, which can significantly increase the benefits. Second, the scale of raising sheep 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. Third, reform the traditional feeding habits. 1. The remixed group grazing is a single group grazing. For the lambs, single-group grazing is performed according to physiological characteristics and life characteristics. The extensive management is carefully managed and the early cultivation is strengthened so that the lambs can eat good milk, early weaning, early grass feeding, and early feeding to speed up their growth and development. 2. Change simple grazing to grazing and feeding. In winter and spring withered grasses, it is difficult for herds 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 save the sheep from physical exertion, but also achieve the purpose of conservation. 3. Change the production of spring lamb to produce winter lamb. Lambs are born in winter. Lambs grow for 10 to 11 months in the same year, which is very beneficial to the winter slaughter in the autumn of fattening in the autumn. This can avoid the wintering of the flock, save manpower and material resources, accelerate the turnover of sheep, and increase economic efficiency. . 4. Extensive feeding management for fine feeding 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 as much as possible, so that sheep eat more grass; winter cold weather, grazing as little as possible, to achieve the right amount of exercise Yes, to add quality hay and fine ingredients; spring weather is cold and changeable, let the sheep run less to eat; hot summer weather, more mosquitoes, catch as soon as possible as soon as possible to graze. Secondly, to make full use of the farm-produced green concentrate feeds, especially lambs, pregnant ewes, and rams, grazing alone can not meet their nutritional needs, so be sure to add concentrate and forage, with particular attention to protein Supplies of 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. Fourth, regular insecticide and medicine bath. During the breeding process, sheep are highly susceptible to both parasites on the inside and outside of the body, resulting in slow growth, low resistance, and serious death. Therefore, the sheep farmers should conduct deworming and medicinal baths every 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. Fifth, do a good job in disease prevention and control. 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.
