It may be that the selection of sheep breeds is incorrect. 1, sheep breeding is incorrect. At present, there are many breeds of sheep, including a series of breeds with high fecundity, high meat yield, strong resistance and fast growth. However, many farmers do not do market research, and directly choose varieties that they think can make money. Of course, most people want to breed sheep breeds with good performance in all aspects, but no matter what kind of sheep, there are certain defects, so we can choose multiple breeds for mixed breeding when choosing breeds. The second is to know which breeds of sheep sell best in the market. 2. Unreasonable capital investment. Many farmers are not skilled in the allocation and management of funds, so there will often be such a situation in the capital investment of breeding, that is, the capital investment in the early stage is large, the capital chain in the later stage can not keep up, and finally there is no way to continue breeding. In fact, raising sheep is not a wealthy industry, and the economic benefits are not so fast. It is a long-term accumulation process. Therefore, it is necessary to arrange the capital investment reasonably and try to save as much as possible under the condition of saving costs. For example, when there are grazing conditions, you can graze or plant grass to raise sheep. Raising sheep in this way is not only low in cost, but also much better in meat quality than many feed-fed sheep, so it can naturally fetch a good price. 3. unscientific feeding management unscientific feeding management is a very important issue. The culture technology is not up to standard, there is no professional culture knowledge, and there is no special culture training, which leads to various problems in the later culture management. Improper feeding management is mainly manifested in the problems of farm cleaning, disinfection, feed collocation, grouping management, temperature and light management, reasonable exercise and so on. If not handled properly, it is a very important reason for the failure of breeding. 4. Disease control is not in place. Disease control is also one of the more important factors. Diseases have a great influence on sheep. For example, anthrax in sheep recently caused serious losses to farmers. Therefore, some commonly used vaccines and drugs should be prepared in farms at ordinary times, which can play a good role in prevention and control. At the same time, check the sheep from time to time and vaccinate the sheep from time to time. 5. I don't know the market situation. Nowadays, many people blindly raise sheep, not only blindly choose sheep breeds and invest money, but also do not investigate the market situation and breeding prospects. Finally, they waited until the time of selling sheep to cram for the last time to understand the market price and sales channels. Finally, there is no channel to sell their own sheepfolds and sales circles, and they can only be sold to some sheep dealers at low prices, resulting in losses.
