Winter fattening sheep technology
Around the winter season to the Spring Festival, which is the season when lamb is listed, the price of mutton is relatively high. Yangyang households can seize the favorable opportunity for long winter according to the individual conditions of goats and adopt scientific methods of fattening to round up the slaughter to obtain a higher economy. benefit. Choose a good variety: A good variety is a highly efficient 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 grouping: Ewes who have poor fertility will be castrated in time, and sheep that are not used for breeding will be castrated in time. All fattening sheep should be kept separately from other sheep and divided into groups according to age, individual, male and female, etc. Management to ensure the best fattening effect of winter sheep. Timely deworming: First, levamisole can be used in combination with avermectin or ivermectin, or 0.3% of veterinary dipterex solution or 12.5% ​​of double-bine glands 1:1000 times solution in fine weather. The body of the sheep 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 enough green hay: Yangyang households must prepare enough fodder before winter, such as vines, stalks, leaves, alfalfa, etc., which can collect soybeans, sweet potatoes, radishes, and root and tuber vegetables, and can also prepare some silage corn. Straw or dry straw for winter feed. In general, a sheep needs 3000 kg of forage in one winter. Appropriate supplements: 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 the hybrid sheep through supplementation can reach more than 200 grams.. Timely slaughter: the growth rate of adult sheep after a certain length of weight is greatly slowed down, and then continue to fatten not only Increasing the cost will also affect the quality of mutton.The fattening time of mature goats after castration will be 30-40% days, and the growth time of growing sheep and lambs can be appropriately extended, generally the fastest growth and development within 6 months of age. High, low investment, large profits.
