Description
Technical Field
The invention relates to the technical field of livestock breeding. More particularly, it relates to a method for improving the flavor of the meat of the lamb.
Background
The Tarim basin multi-wave sheep are meat fat dual-purpose coarse and semi-coarse sheep formed by mixing blood of local soil breeding sheep and Afghanistan warky hip sheep, are excellent local meat varieties cultured by long-term natural selection and manual selection, and enjoy high reputation in Xinjiang; the Dulang mutton has the advantages of meat fragrance, delicious taste, light mutton smell and the like, is known to everyone and has witnessed sight, and the thumb is raised as long as the Dulang mutton is tasted by local people or domestic and foreign friends who travel from the basin; is a bright pearl in meat variety. Dolang sheep are mainly produced in the counties of Magaiti, Bacchu and Shache, in the counties of Hedong, and are spread over vast rural areas throughout the entire region, in the provinces of Yili, Aletai, Hami, Bazhou, Aksu, Kzhou, and Tian.
The Duolang sheep has the advantages of large body, precocity, rapid growth and development in early stage, great potential for later-stage weight increment, high reproduction rate, estrus all year round, two-yield in one year, multiple lambs in one yield, high meat quality, low cholesterol content, high feed reward and the like. The average weight of the yearly-aged stud rams is 66.7 kilograms, and the average weight of the female rams is 59.88 kilograms; the average weight of an adult ram is 118.92 kilograms, and the average weight of an adult ewe is 79.89 kilograms, so that the goat is a preferred variety for developing modernized mutton sheep industry in rural areas, and is an advantageous resource with huge development potential for poverty alleviation and enrichment and national strong people.
Glutamic acid, cystine and methionine can increase the delicate flavor and fragrance of mutton, so that the mutton is delicious and has good taste. Stearic acid is an important fatty acid causing the smell of mutton, and when the flavor of the mutton is considered, the reduction of the quality of the mutton caused by over strong smell of the mutton is controlled. The growth advantages of the goat are fully exerted in the cultivation of the Dulang sheep, the production benefit is improved, and the high-quality mutton is produced and the quality of the mutton is improved. Therefore, the lamb with high wave is generally weaned in 3 months, in order to ensure that the mutton has good flavor and high market price and sales, the lamb is generally slaughtered in about 3 months after weaning, and if the lamb is weaned right in winter, the lamb with high wave can only be bred by corn flour and silage. The feed intake rate of the weaned lambs to the coarse fodder is less than 50%, the cost is high and the flavor is poor by using the corn flour as the fine fodder, and because the weight of the unrestrained lambs is increased when the unrestrained lambs are slaughtered by more than 40 kg, the flavor becomes worse and worse, the market acceptance is gradually reduced, and the selling price of each kg is also lower and lower.
