Develop forage resources and provide balanced supply throughout the year Under the premise of vigorously developing existing forage fodder resources, some high-quality forage grasses should also be planted. During use, they should be properly matched, and a certain amount of dry, roughage, and concentrate feeds should be fed daily to meet the nutritional needs of the diet. It can also reduce the incidence of diseases caused by feed factors and reduce the cost of feeding. Sheltered sheep building should be standardized and scientific The construction of sheep houses must take into account the sheep's preference for dryness, disgusting wet habits and local climatic conditions. All localities should select suitable building materials and suitable sheep building patterns according to the local natural conditions, and strictly follow the sheep's habits and eating habits to conduct scientific and rational design and construction, and must not construct buildings at will. Selecting high quality varieties for hybrid use For the species to be bred, the species with strong adaptability, high production performance, good product quality, short feeding period, and high economic benefit should be selected according to local conditions. Sheep can use Charolais, Suffolk, Dorset and so on. Domestic breeds can be selected for crossing with small sheep and local sheep. Goats should vigorously promote crossbreeding techniques that use Boer goats to improve local production by improving hybrid goats. Adopt advanced breeding technology The sheep belong to estrus animals in the short-day sunshine season. There are certain individual differences in the signs and duration of estrus, especially in the case of house feeding. Owing to the lack of estrus detection methods, the most suitable breeding time is delayed, resulting in greater reproductive production. loss. Advanced breeding management techniques should be adopted to increase sheep breeding efficiency and lambing rate, shorten lambing intervals, centrally cultivate lambs, and increase the survival and breeding rate of lambs. The specific requirement is to change the passiveness and initiative in the breeding of sheep. At the most favorable time for the production of fodder, artificial insemination technology is used to breed, breed lambs, cultivate lambs, maximize the utilization value of breeding sheep, and improve the economy. benefit. Fattening technology Under house-feeding conditions, short-term fattening is generally used to achieve the desired weight gain. Lamb fattening is generally 6 to 8 months old, and the market weight is 25 to 35 kg. At the same time, according to the breed type, age, live weight, public opinion and weight gain plan of the fattening sheep, appropriate feeding standards and determining the fattening dietary standards should be selected. The composition of fattening rations should be sourced locally and raw materials should be diversified. Concentrates can account for 45 to 50% of the diet. The fattening sheep house is 0.75-0.95 square meters for each lamb and 1.1-1.5 square meters for big sheep. In management, summer should pay attention to heatstroke cooling, winter should pay attention to cold and warm, so that it is warm in winter and cool in summer. In the summer and autumn, the excrement should be removed promptly and the ventilation should be kept well. Forage, feed, and drinking water should be kept clean, mildew-free grass and materials should not be provided, and deep well or warm water should be consumed in winter and early spring, and drinking and clean water in summer.
