Seasons before and after the Spring Festival is the peak season for mutton listing. The price of mutton is relatively high. Yangyang households can seize the opportunity for long winter according to the individual conditions of goats and adopt scientific methods of fattening in batches for slaughter to obtain higher economic benefits. . Choosing good breeds is a good basis for raising sheep. It is optional to breed offspring of Boer goats, horse head goats, Saanen dairy goats, Nanjiang yellow goats and other local goats, because of the high breeding rate, slaughter rate and fast growth rate of this hybrid goat. Timely grazing of those ewes with poor fertility in time, and timely castration of lambs that are not used for breeding. All fattening sheep should be kept separately from other sheep, and divided into groups according to different ages, individuals, and parents. To ensure the best fattening effect of winter sheep. Timely deworming First, use levamisole in combination with avermectin or ivermectin, or use 0.5% veterinary solution or 12.5% ​​of bifidobacterium 1:1000 in fine weather. The solution was sprayed on the sheep body to remove 80% of the parasites inside and outside the sheep. Secondly, targeted drugs were used to repel certain parasites such as trematodes, cockroaches and cerebral lice. At the same time as deworming, prevention of epidemic diseases such as sheep dysentery, sheep aphthous disease, sheep pleuropneumonia, sheep epidemic disease, and goat pox should be done to avoid affecting the fattening effect. Prepare ready-made green grass Yangyang households must prepare enough fodder before winter, such as vines, stalks, leaves, alfalfa, etc., which can collect soybeans, sweet potatoes, radishes and other crops and root and tuber vegetables, as well as some silage corn stalks. Or dry straw for winter feed. In general, a sheep needs 3000 kg of forage in one winter. Appropriate supplementary feeding and fattening can achieve the best slaughter effect. While ensuring that fattening sheep eat enough forage every day, they should also feed their appropriate amount of concentrate to ensure their nutritional needs. The diet should contain 60% to 70% of roughage (30% to 40% of hay, 30% to 40% of straw, 30% to 40% of snow, and any sheep can freely feed and freely drink water.) The formula is corn 48.9%, soybean meal (or cotton cake, vegetable cake) 10%, wheat bran rice bran 30%, distiller's grains 10%, salt 0.1%, additive 1%.Generally every sheep is fed 100 to 150 grams of mixed concentrate feed daily. The concentrate feed can not be fed too much at a time, so as to prevent the sheep from suffering from gastrointestinal diseases.The daily gain of the improved hybrid sheep can reach more than 200 g through timely feeding. The growth rate of the grown sheep can be slowed down when the sheep grows to a certain weight. The fattening will not only increase the cost but also affect the quality of the mutton.The fattening time of adult goats after castration ranges from 30 to 40 days, and the growing time of growing sheep and lambs can be appropriately extended, generally the fastest growing and developing within 6 months of age. High returns, low investment, and high returns.
