A brief analysis of the scientific breeding and barning techniques of the Xinji fine wool sheep

Xinji fine wool sheep is more beautiful in appearance, the body shape is symmetrical, the side is rectangular, the face is smooth, the chest is wide and deep, the back is straight, the body is round, the coat is white, most of the Xinji fine hair sheep ram has horns, the neck is loose, and the ewe has no horns. Adult rams weigh about 65 kg and adult ewes weigh about 38 kg. In breeding and production, farmers should be careful to prevent the close mating of the New Ji fine wool sheep, and they should exchange various rams, and the breeding rams in one flock should be used for two consecutive years, and then exchanged with the breeding rams of the same breed in other flocks. Reduce the number of inbreedings. Breeding rams are kept separately. In the breeding season, according to the blood relationship, the breeding rams with distant blood relations are selected for artificial auxiliary breeding or artificial fertilization. This method not only avoids inbreeding, but also controls the lambing time of the ewe and extends the life of the breeding ram.

Generally in the breeding season, about 1 kg of concentrate should be supplemented every day, of which oil cakes should account for one-third, and the rest should be fed to corn, barley, bran, dried melons and so on. You can also use grass such as planted grass, pasture grass, etc., the use of high-quality green hay and other roughage feeding, in the lack of grass, in addition to feeding artificial grass, you can also supplement carrots or pumpkin and other juicy feed 1 kg per day to ensure the need for vitamins. To prevent the miscarriage of pregnant ewes, farmers can start from enhancing the physique and disease resistance of pregnant sheep and effectively do a good job in breeding management. Do not feed moldy, acidic, frozen and toxic feed, do not drink cold and dirty water, and can not drink water on an empty stomach. The sheep barn feeding trough should be disinfected regularly and regularly, pay attention to weather changes, and prevent sudden winds and cold waves from making pregnant sheep sick. Usually, we should pay attention to observing the spirit, diet, movement and excretion of feces in pregnant sheep, and treat abnormalities immediately. For pregnant sheep with symptoms of early miscarriage, 10-30 ml of progesterone is injected once a day until the symptoms disappear.

The breeding of Xinji fine wool sheep does not make money, then it is necessary to grasp the time, in the appropriate weight of the column listing, which is the key link to improve the economic benefits of the New Ji fine wool sheep, the appropriate body of the New Ji fine wool sheep out of the pen is important according to the daily weight gain, feed utilization, slaughter rate and other production performance indicators and market demand to comprehensively determine. The weight of the pen is too low, the growth potential of the New Ji fine wool sheep is not fully utilized, and the meat production is also low; the weight of the pen is too high, although the meat production increases, but the feed utilization rate decreases. The peak period of growth of Xinji fine wool sheep is slower than that of local sheep, and its suitable weight should be larger than that of local sheep.
