Farmers can't raise sheep only by grazing. They want to build a simple enclosure in the yard to keep out the wind and rain. Simply relying on grazing leads to unstable productivity. In summer and autumn, they gain weight, while in winter and spring, they grow slowly. It is necessary to change with the seasons, not to feed in summer and autumn, and to supplement excellent feed in winter. In winter and spring, it is necessary to combine animal husbandry and housing to prevent "thin winter and lack of spring". In addition, grazing is prohibited in mountainous areas because of returning farmland to forests, and farmers in plain areas reclaim land for farming, so the scope of grazing is getting smaller and smaller. Therefore, semi-grazing and semi-shed feeding are most suitable for farmers to raise sheep.
Advantages of semi-grazing and semi-house-feeding: In the season when green and yellow are not connected, sheep can eat green feed with various nutrients, which can not only meet their physiological needs, but also exercise their physique through wandering grazing and achieve the purpose of promoting health. After grazing for more than 6 hours, sheep don't need to be fed except drinking light salt water, which reduces the investment. House feeding can fully play its role in rainy season, winter and spring, and grass and feed can be added on time to make the life of sheep regular and prevent hunger from affecting the health of sheep.
(2) Problems that farmers should pay attention to when raising sheep.
1. Cooperation among sheep farmers.
Sporadic sheep farmers in rural areas should organize joint ventures and set up sheep raising consortia. The first is the memory problem. Choose 3~5 households in the consortium to raise a ram with good character and provide paid services for other farmers. The consortium can also establish relations with nearby sheep farms. In addition to learning sheep breeding techniques, the sheep of the consortium members can also go to the sheep farm for artificial insemination during estrus, which avoids the loss caused by raising sheep in every household and reduces the production cost. That is, the prevention and control of recurrent diseases: farmers who raise sheep sporadically should also pay attention to the prevention and control of diseases. According to the local breeding experience, they should be injected with vaccines such as "three-four prevention" and "foot-and-mouth disease" on time. Farmers think that there are few sheep and it is not worth immunization. Moreover, once the vaccine is opened, it will be thrown away, causing waste. The consortium can purchase high-quality vaccine, inject epidemic prevention, purchase insect repellent and inject uniformly, which not only reduces consumption, but also ensures the healthy growth of sheep. In addition, the farmers' sheep-raising consortium can attract enough attention in purchasing medicine, selling sheep and learning successful breeding experience, give full play to the role of farmers' sheep-raising consortium, and improve farmers' sheep-raising efficiency.
2. update concepts and technologies.
The biggest disadvantage of farmers' raising sheep is their low management level, and they never pay attention to sheep nutrition and disease prevention. The nutritional deficiency of sheep can be ignored in grazing season, but special attention should be paid to the nutritional problems of sheep in spring and winter when forage is scarce. Every spring and summer, more and more sheep die of malnutrition and anemia.
Preventive measures:
(1) Harvest and dry in the lush season, stack and store, pay attention to rain and mildew, and store corn stalks in autumn. Don't be insatiable and don't pay attention to quality. The original EM fermented forage was chopped in spring and winter and put into plastic bags with a width of 1m and a length of 2m. Four to six plastic bags were divided into two groups to ferment forage alternately, which can meet the needs of sheep farmers.
(2) feeding at the right time. Feed should be supplemented in time in winter, with pregnant ewes 100- 150g and pregnant ewes 200-450g. Ingredients should make full use of bran, sweet potato residue, bean curd residue, corn husk, corn flour, etc. 0.05g/kg of iron-containing additive, 0.5% of sodium chloride, 2% of calcium hydrogen phosphate, 0.8g/kg of sodium selenite and vitamin E0. Use B 12 powder and 0.8g/kg multivitamin twice a month for one week to prevent malnutrition and anemia.
(3) Pay attention to feeding management and scientific nutrition and health care.
