In recent years, mutton sheep breeding is becoming a sunrise industry. Judging from the current international mutton market, the output is declining. Since the outbreak of "mad cow disease" in Britain, strict quarantine and mass slaughter have been carried out all over Europe, resulting in a reduction in mutton production of about 10%, about1/0000 tons, and the self-sufficiency rate has dropped from 8 1% to 76%. The United States opened the mutton market to Australia and New Zealand, and the output of Australian and New Zealand mutton decreased by about 2,000 tons. The cold winter in Russia in recent two years has led to a decline in the number of mutton sheep and limited mutton production. From the perspective of sheep industry in pastoral areas in China, mutton production has also been restricted to a certain extent. First, the grassland ecological environment in pastoral areas has deteriorated, grassland degradation and digestion have been serious, and forage yield has decreased, forcing pastoral areas to take compulsory grazing prohibition measures to reduce grassland carrying capacity. Second, two years ago, the pastoral area suffered a snowstorm that had never happened in 50 years. Just because of the cold weather and the lack of forage, a large number of sheep died. It will take at least 4-5 years for these areas to resume normal production. Due to the above factors, the mutton market is promising and the market demand is increasing. Internationally, due to the influence of livestock diseases, a large number of cattle and sheep in Europe are buried or burned. Broilers and pigs grow too fast, and their meat quality and palatability are getting worse and worse. In addition, a large number of hormones and drugs are used in the feeding process, which causes people's worries and even panic. Mutton has gradually become an ideal and safe substitute. The protein content in mutton is 12.6%- 15.2%, and the fat content is 6.6%- 13. 1%. In mutton protein, the content of lysine is higher than that of beef, pork and chicken, and the content of thiamine and riboflavin is also higher than that of other meats. In the process of feeding, sheep mainly use forage, rarely use concentrate and feed additives, which reduces the possibility of epidemic spread and has extremely low drug and hormone residues. It is a kind of natural health food which basically conforms to the modern consumption concept. In recent years, instant-boiled mutton has become one of the popular foods. Under the influence of these factors, the consumption of mutton shows a linear upward trend. From the benefit of mutton sheep breeding, mutton production is also a relatively stable project. In the first generation of small-tailed Han sheep, ewes can produce 3.7 live lambs every year, and the average weight of lambs when they are released is 40 kg, all of which are fed on crop straws, weeds and leaves. The price of live sheep in the market is 7 yuan per kilogram, and the output value of each ewe is above 900 yuan. As a sheep farmer, the cost of each sheep does not exceed 100 yuan. If each labor force raises 10 ewes every year, its output value can reach more than 8,000 yuan and its net income can reach more than 5,000 yuan. With the same investment, the market of livestock and poultry products such as pigs, chickens and cattle is unstable and the price fluctuates greatly. Because the breeding of mutton sheep is relatively slow, and the increase of the number is in a dynamic balance with the market demand, raising sheep has become a rich project with less investment, less risk, quick effect and stable income.
