First, the main growth characteristics of the small-tailed cold sheep analysis
1. Introduction to appearance characteristics
The small-tailed cold sheep has a relatively well-proportioned body, and the overall appearance is cylindrical, with a moderately sized head, and a good combination of head and neck. Its limbs are high, both the anterior and posterior drives are developed, the waist and back are straight, the eyes are relatively large and energetic, the nose is large, the bridge of the nose is high and raised, the ear size is medium, and the sagging. Brown or black spots are common on the head of the small-tailed cold sheep, the tail fat is short, the ram's tail is rounded and fanned, and the tip of the tail is turned up. The coat color of the small-tailed cold sheep is mainly white, and some sheep have brown spots or black spots on their heads and limbs, which are classified according to the coat, which can be divided into three types, namely coarse hair type, fine hair type and fur type.
2. Characteristics of varieties
Small-tailed cold sheep in the early stage has a faster growth and development rate, and its appearance is larger, the quality of meat is good, with the characteristics of four seasons of estrus, and the small-tailed cold sheep reproductive performance is strong, with stable heredity, compared with other types of sheep, its quality characteristics are more prominent, so that the breeding industry is more recognized is its multi-lamb and prolific characteristics. The small-tailed sheep have earlier sexual maturity, begin to be in heat at 5-6 months, and give birth to lambs in the same year. When the little-tailed sheep reach the age of one, the average weight of the ram is 65 kg and the average weight of the ewe is 46 kg. Adult rams weigh an average of up to 95 kg, while ewes weigh 49 kg. The small-tailed cold sheep has a strong adaptability, is not picky about roughage, and can be used for daily feeding with a wide variety of feeds, and if it is domesticated for a long time, it can develop captive habits, and the overall breeding success rate is very high.
Second, strengthen the practical application of breeding management technology
1. Control of the feeding management process of ewes
For farms, ewes are the basis of breeding, but also the main body of breeding, in order to ensure the health and condition of the ewe, it is necessary to give sufficient nutritional supply, when it is bred and pregnant, can provide enough growth energy for the fetus, and in the ewe after giving birth to sufficient milk, help the lamb to survive. During the non-pregnant period, it can be guaranteed that the diet of ewes is 0.3-0.5 kg of mixed refined feed, and 1.5 kg of hay needs to be provided in winter, plus 1 kg of silage or other types of green and succulent feed, if the ewe is in pregnancy, it is necessary to appropriately increase the amount of feed according to the actual situation. If grazing measures are taken for ewes, supplementary feeding is needed, and what needs to be paid more attention to is to do a good job in the daily management of feed and avoid feeding rotten, mildew or frozen feed, which can easily lead to abortive or disease of ewes.
2. Breeding management process control of breeding rams
In the small-tailed cold sheep, the number of breeding rams is relatively small, but the quality it has has a great impact on the reproduction of offspring, so the requirements for its breeding management are relatively high. In the breeding process of breeding rams, it is necessary to ensure that they have good physical condition, can not be overnutrition, resulting in obesity, but also can not be raised too thin, and then ensure that they have good quality semen and strong sexual desire. For the feed of breeding rams, it is not only necessary to have a scientific ratio, but also to have a strong diversity. To control the weight of breeding rams in the breeding period to about 80-90 kg, it is necessary to feed them 1 kg of refined feed, 2 kg of wild licorice or alfalfa hay, 1.5 kg of carrots, 15-20 g of table salt and 10 g of bone meal. In the non-breeding period, 0.5 kg of refined feed can be fed, and there is no restriction on roughage. In terms of feeding methods, 2-3 feedings can be used, and if the breeding period is in place, 1-2 fresh eggs can be added, and the amount of exercise is sufficient.
3. Control of lamb feeding management process
For the breeding of lambs, the main thing is to make it as full as colostrum as possible, while the lack of milk of lambs to carry out reasonable supplementary feeding, because the small tail cold sheep has the characteristics of multiple births, so if a fetus in more than 2-3 sheep need to be properly fed, you can use artificial methods, the use of goat milk, milk or milk powder for supplementary feeding, but the need to control the amount of feeding, health conditions and feeding quality. If conditions permit, to strengthen the practical application of lamb early weaning technology, under normal circumstances, when the lamb is 10-15 days old, you can give some fresh vegetable leaves or grass, you can also choose soft and easy to digest leaves and hay, promote the development of the lamb's digestive system. You can use sautéed soybeans or corn, grind them reasonably, and let the lamb lick them, or add them to the water to drink. Feeding according to the above methods, when the lamb reaches 20-30 days, can start normal feeding.
4. Control of the feeding and management process of fattening sheep
For lambs aged 3-4 months, straight-line fattening can be carried out, which can make them grow rapidly and get out of the pen early. Breeders should do the relevant preparatory work before carrying out fattening, first of all, to cut off the tail and castrate the lamb, the tail break can be carried out 1-3 weeks after the birth of the lamb, but the relatively best time is 2-7 days, castration and tail break can be carried out at the same time. If there is a trauma surface after the completion of the above two tasks, you can use 5% iodine wine for disinfection treatment; secondly, to do a good job of stomach deworming work for lambs, combined with the actual weight of lambs, feed according to 5g worm star powder or 2 worm buster capsules per 5 kg body weight, within 3d of the deworming drug feeding, each time need to use 25g of stomach powder, while yeast tablets 5-10 pieces, mixed with feed and fed, twice a day. You can use two ways of grazing fattening or house feeding fattening, if it is house feeding fattening, you need to adhere to the order of first coarse and then refined, while ensuring that the first material is fed after the water.
3. Effective measures for disease prevention and treatment
In terms of disease prevention and control, breeders need to carry out deworming work in late winter and early spring and autumn every year, if it is in summer, due to the hot weather, it is necessary to shear the hair first, and then take a medicinal bath, and at the same time need to strengthen the attention to immunization work, such as the vaccination of sheep rapid epidemic, sudden sniping and enterotoxemia triple vaccine, and also need to inoculate sheep pox seedlings. Attention should be paid to the hygiene of farms and sheep barns, regular cleaning and disinfection, and timely anti-mosquito and insect repellent.
Fourth, the small tail cold sheep has a strong ability to adapt to the environment and multi-lamb, prolific and other capabilities, and the success rate in daily breeding is relatively high, favored and recognized by the breeding industry, in order to improve the breeding performance of the small tail cold sheep, it is necessary for the farm to strengthen the attention of ewes, breeding rams, lambs and fattening sheep, do a good job in daily breeding management, and then increase their own economic benefits and improve the development efficiency of the breeding industry.
