Every year from the winter season to the Spring Festival, it is the peak season for lamb to be listed. The price of lamb is high. The sheep owners can seize the opportunity of the long winter according to the individual conditions of the goat and adopt scientific methods of fattening to round up the slaughter to obtain a higher economy. benefit. 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, levamisole can be used in combination with avermectin or ivermectin, or on sunny days 0.3% veterinary solution of dipterex or 12.5% ​​of double thymus gland 1:1000 times solution In the body, it removes 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, and 30% to 40% of concentrated feed. Any sheep can freely feed and freely drink water. The reference formula for refined feed is 48.9% corn, soybean meal or cotton cake, 10% vegetable cake, 30% wheat bran rice bran, 10% distiller's grains, 0.1% salt, 1% additive.Generally, each sheep feeds 100-150% grams of mixed concentrate on a daily basis. Can not feed too much, so as to avoid sheep suffering from gastrointestinal diseases.The daily weight gain of supplemented sheep can reach more than 200 grams.When the adult sheep grows to a certain weight, the growth rate is slowed down, and it is not only the increase of fattening. The cost will also affect the quality of the mutton.The fattening time of adult goats after castration is 30-40%, and the growth time of growing sheep and lambs can be appropriately extended, generally the fastest growth and development within 6 months, and the high feed reward , less investment, large profits.
