Adults have ceased to grow and develop. To increase their fat deposition requires a large amount of energy, and other nutrients are only used to maintain life activities and to meet the needs of restoring the optimal state of muscles and other tissues and organs. Therefore, their nutritional needs are lower than lambs in addition to heat. When fats are grown for adult sheep of general breeds, the amount of heat energy required to achieve the same weight gain is slightly higher than that of meat breeds, which should increase by about 10%. During the fattening process, the meat quality of the sheep changes. With the improvement of the moisture content, the composition of the lamb is relatively reduced, the fat content is increased, the amount of heat produced is increased, and the protein content is relatively decreased. A comparative study of the changes in meat and fat content at different fattening stages of adult sheep demonstrated that the weight gain of adult sheep is almost entirely fat.
Prior to fattening, comprehensive health checks should be performed on the sheep. All sick sheep should be cured after fattening, and diseased sheep that cannot be treated should not be fattened. Sheep who are old and have difficulty in feeding do not need to be fattened, otherwise they will waste forage feed and will not achieve the expected results. Ramping the rams should be cast off about 10 days before fattening. Ewes can be bred to make them pregnant and to be fattened immediately after lambing. Adult sheep fattening period should not be too long, because the body's ability to deposit fat is limited, and when it is full, it will not increase again. Therefore, the fattening period is appropriate for 2 to 3 months, but at the same time, according to the fat condition of the finishing sheep, it is necessary to have a flexible grasp of the fattening time. In the grassy period, where there are grass slopes, the poorly-worn adult sheep can be bred and raised first. Using grass to reclaim the sheep and then fattening can save feed and reduce costs. During the fattening period, the rations should also be adjusted in accordance with the degree of glutinous growth, extended the fattening period or ended the fattening ahead of schedule. Usually weighing methods can be used to check the sheep's weight gain rate, or use the appearance method, touch method to determine the degree of their manure.
The sheep can be grazing and fattening where wild grasses are abundant, where the terrain is flat, and where water is available. However, it is difficult for sheep to be slaughtered in a short period of time by grazing alone, and it is difficult to reach fullness. It is generally advisable to grazing for 1 to 2 months, and in the later period, there should be no less than 1 month of feeding and fattening period, and the use of high-concentrate diets can be used to fatten the mutton in order to achieve the purpose of improving the quality of mutton. If there is a shortage of concentrate in this area, it can be grazing or feeding grass for about 4 months, and then feeding and fattening for 1 month, while restricting its exercise, it can be fattened and slaughtered in a short period of time. When adult sheep are grazing and fattening, if they are lack of pasture in spring, they should pay attention to feeding. In the case of free access to roughage, each sheep was fed a daily supplement of 0.75 kg of corn, wheat bran, and a small amount of soybean cake. When the pasture was abundant, the amount of supplement could be appropriately reduced.
Sheep fattening
The culling sheep and old cashmere sheep used for fattening are all adult sheep. This type of sheep is generally older and has a low meat yield and poor meat quality. After fattening, the fat between the muscles increases, the subcutaneous fat increases, the meat becomes tender, the flavor is also improved, and the economic value is greatly improved.
