First, it is necessary to select good breeds of sheep breeds according to local conditions, large body size, fast growth, high reproduction rate, strong adaptability, good meat quality, and high efficiency, mainly Boer goats, Sha Neng goats, Huang Huai goats and so on. Most of the goats currently reared are native breeds, with small individuals, slow growth, and low slaughter rates, so the benefits are 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.
Secondly, the scale of family-scale sheep breeding should be sufficient. 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. General professional households can breed 15 to 25 fertile ewes.
Third, we must reform the traditional feeding habits
1, regrouping grazing for single group grazing. For the lambs, single-group grazing is performed according to physiological characteristics and living characteristics. Extensive management is carefully managed, and early cultivation is strengthened so that the lambs can eat good milk, early weaning, early grazing, and early feeding to speed up growth and development.
2, to change the simple grazing combination of grazing and feeding. In the withered grass period, it is difficult for the flock to meet its nutritional needs by grazing alone. Therefore, half-day grazing and half-day supplementary feeding are adopted in winter and spring to avoid the sheep consuming only physical strength and achieve the purpose of conservation.
3, change the production of spring lamb for the production of winter lambs. Lambing in winter, the lamb's growth period lasted for 10 to 11 months, which is very beneficial to the winter slaughter in the autumn of fattening in the same year. It can not only save the sheep from wintering and save manpower and material resources, but also accelerate the turnover of sheep and increase economic efficiency.
4, change the extensive feeding and management for fine feeding management. First of all, do a good job of seasonal grazing, autumn herbaceous seeds high nutritional value, is the golden season of grazing, as much as possible to grazing, so that more sheep grazing; winter when the cold is less grazing, moderate exercise can be, to add quality hay and fine materials; The weather in the spring is cold and changeable. Let the sheep run less and eat more. In the summer, the weather is hot and there are more mosquitoes and flies. Second, make full use of self-produced green sperm feed supplement. Lambs, pregnant ewes, and rams, in particular, cannot meet their nutritional needs because of grazing alone. Therefore, they must always supplement concentrates and forages, with particular attention to the supply of proteins, minerals, and vitamins. Third, pay attention to providing clean drinking water and improving environmental hygiene. Sweep the sheep house every day and clean the trough and sink to ensure that the sheep house is cool in winter and cool in summer.
Fourth, regular deworming and medicinal bathing sheep in the breeding process, can easily be infected on the body and the external parasites, resulting in slow growth of sheep, low resistance, serious will also cause death. Therefore, insect repellents and medicinal baths should be carried out every year according to the parasite prevalence. Usually the first insect repellent in the spring, and more with levamisole or insect nemesis drive nematodes, every 5-7 days and then use nitrochloropolistic nematode 1 times, and then again in autumn. The medicinal bath is conducted once a year in spring and autumn, and the weather is warm and sunny. The water temperature is 35° C., and 0.5% to 2% of trichlorfon is used to add sulfur for 1-2 minutes.
Fifth, we must do a good job in disease prevention and control Lamb dysentery, streptococcal disease, brucellosis, No. 5 disease, infectious pyrematitis, etc., which are more harmful to sheep, should be well prepared for vaccination and integrated prevention and control. Perform a reasonable immunization program.
