How to raise sheep's benefit
First, the selection of fine varieties according to local conditions, the development of improved hybrid sheep good size, rapid growth, high reproduction rate, strong adaptability, good meat quality, high efficiency. At present, there are mainly Boer sheep, Sha Neng goats and Huang Huai goats. Most of the goats raised by farmers nowadays are mainly local breeds, with small individuals, slow growth, low slaughter rate, and low efficiency. In order to reverse this situation, Boer goats and Saanen goats should be introduced for crossbreeding purposes. For example, Boer goats and local goats can be crossbred. When they are 6 months old, they can gain nearly 10 kilograms more than local goats, which can significantly improve the benefits. Second, the scale of raising sheep should be appropriate for family size. It can be determined based on 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, the reform of the traditional feeding habits 1. Reconstitute the group grazing for a single group of 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. Change simple grazing to combine grazing and supplementation. 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 adopted in winter and spring to avoid the sheep consuming only physical strength and achieve the purpose of conservation. 3. To change the production of spring lamb for winter lamb production. Lambing in winter, the lamb's growth period of 10 to 11 months that year is very beneficial to the winter slaughter in the autumn of fattening in the same year. This will not only save the sheep from wintering, but also save manpower and material resources, accelerate the turnover of sheep and increase economic efficiency. 4. Change extensive feeding management for fine feeding management. First of all, we must do a good job of seasonal grazing, and the weather in autumn is cool. Baicao seed has high nutritional value and is a golden season for grazing. At this time, it is necessary to grazing as much as possible so that the sheep can eat more grass. In winter, the climate is cold, grazing is as low as possible, and proper amounts of exercise can be used to supplement high-quality hay and concentrates; the spring weather is cold. Changeable, let the sheep run less to eat; hot summer weather, mosquitoes and more, catch as soon as possible as soon as possible two grazing. Secondly, to make full use of farm-produced green concentrate feeds, especially lambs, pregnant ewes, and rams, grazing alone can not meet their nutritional needs, so it is always necessary to supplement concentrates and forages, 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 deworming and medicinal bathing sheep in the breeding process, can easily be infected on the body, the external parasite, resulting in slow growth of sheep, low resistance, serious will also cause death, so the sheep should be based on the parasite epidemic , annual deworming and medicine bath. 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 to 12, 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 of sheep Lamb dysentery, streptococcus disease, brucellosis, No. 5 disease, infectious conjunctivitis, etc., should do a good job of vaccination and integrated prevention and control work, strict formulation And perform a reasonable immunization program.
