I am from Yongcheng, Henan Province. I want to raise sheep. I don't know which kind of sheep is suitable.

I want to raise sheep in Yongcheng, Henan Province. I don't know which kind of sheep is suitable-- the following two kinds of sheep are more suitable: small-tailed Han sheep are produced in southern Hebei, eastern and northeastern Henan, southern Shandong and northern Anhui and northern Jiangsu. Small-tailed Han sheep are mainly distributed in Jiaxiang, Cao County, Wenshang, Liangshan and other counties of Shandong Province and some areas of northern Jiangsu, northern Anhui and Henan. The producing area belongs to Huang-Huai alluvial plain with low topography, fertile soil and mild climate. The annual average temperature is 13: 15 ℃, January is-14: 0 ℃, July is 24: 29 ℃, annual precipitation is 500: 900 mm, frost-free period is 160-240 days. The producing area is one of the main producing areas of wheat, miscellaneous grains and cash crops in China. Crops can be cropped twice a year or three crops in two years, rich in agricultural and sideline products, and provide a lot of forage for raising sheep. Breed characteristics small tail Han sheep are symmetrical in shape and strong in physique. The bridge of the nose is bulging and the ears are big and drooping. The ram has a large neck and a large spiral angle, while the ewe has a small neck with small horns, ginger horns or horns. The ram has a deep chest, high hammerhead, straight waist, tall body and square side view. The limbs are stout and the hooves are strong. The fat tail is slightly oval, with a longitudinal groove at the lower end, and the tail length does not exceed the hock joint. The hair is white and heterogeneous, with a small amount of dry dead hair, a few individuals with color spots on the head, and some sheep with black bristles around their eyes. According to the shape of the coat, it can be divided into three types: fur type, fine hair type and coarse hair type, with a proportion of 52.89%, 39.58%, and 7.53%, respectively. Fur-type small-tailed Han sheep have a large number, large physique, high lambing rate, clear wool strands, many and obvious flower bends, beautiful spikes and high value in making fur; fine-wool small-tailed Han sheep have fine and dense hairs, unclear wool strands, less flower bends, delicate and compact physique, small physique and good meat production. The number of coarse wool small tail Han sheep is less, the wool strands are curved, the wool is rough and dry, there are more dry dead hair, the physique is large and the bones are loose. The average body height of adult rams and ewes is 90.33 cm and 80 cm respectively; the body height of 6-month-old rams and ewes is 70.54 cm and 68.66 cm respectively; and that of 12-month-old rams and ewes is 82.55 cm and 75.80 cm respectively, reaching 91% and 94.75% of that of annual rams and ewes, respectively. 2. The birth weight of male and female lambs is 3.72kg and 3.53kg respectively, that of 3-month-old male and female lambs is 27.08kg and 23.68kg, that of 6-month-old male and female lambs is 47.60kg and 38.15kg, that of one-year-old male and female sheep is 113.92 kg and 70.10kg respectively, that of adult male and female sheep is 160.52 kg and 72.30kg respectively. Growth and development characteristics 1. body weight development characteristics of small-tailed Han sheep the body weight of adult ram is 80.50 kg and that of adult ewe is 57.30 kg. The body weight of rams and ewes is poor after 5 and 18 months of age, respectively: the sex difference increases significantly from the first year of age, which may be less than that of the remaining ram and can be well cultivated in the early stage. In fact, how to put the head of the  stem, the Qin and the leg on the head of Laiqin, the discharge of D-stalk isthmus? It basically increased steadily from the age of month to adulthood, and the maximum monthly increase occurred at the age of 2, 3 and 10 months, which was 5.8 kg / month, 5.4 kg / month and 4.5 kg / month respectively, and the body weight of ram increased more frequently at the age of 2, 3, 6, 9 and 11 months, respectively, indicating that the weight of ewe was precocious than that of ram. The body height, length, chest circumference and tube circumference of adult rams are 90.33cm, 94.33cm, 110.33 cm and 10.50cm, respectively, while those of adult ewes are 80.00cm, 82.96cm, 100.35 cm and 9.04cm respectively. Compared with body weight, the increase of body size was more uniform, and the gender difference was not significant, but the mass consistency of each body size of ewes was significantly better than that of rams. The common feed of small-tailed Han sheep: green feed: 1 green corn, sorghum 2 green barley, oats 3 ryegrass 4 awnless brome 5 alfalfa 6 sweet clover 7 purple yunying, etc., can be directly fed, can also be prepared into hay or made into silage. Coarse fodder: 1 hay 2 straw (corn straw, wheat straw, rice straw, rice straw, bean straw, etc.) 3 blighted husk (bean pod, grain husk, cottonseed shell, etc.) silage: 1 green cut corn with ear corn 2 green corn straw 3 main points of all kinds of silage raw materials: the fine stem forage should be 7-8 cm, and the thicker straw such as corn should not exceed 1 cm. -- Reproductive characteristics 1. The average proestrus of sexually mature small-tailed Han sheep is 186-255 days, and there is a great difference in sexual maturity, mainly because sexual maturity is affected by birth season, number of lambs, birth weight and growth and development. The weight of a 6-month-old ewe is 60% of that of an one-year-old sheep, but its uterus weighs more than 76% of its one-year-old uterus. Thus it can be seen that the early maturity of reproductive organs is an important germplasm characteristic of high fecundity varieties. The ram of Han sheep with small tail matures at the age of 5 months. The young ram has sexual desire and climbing behavior at the age of 4 months, and the penis is aroused at the age of 5 months. 85% of the mature sperm were found in the vas deferens at the age of 5 months and 100% at the age of 6 months. At this time, the sperm density in the original semen was 3 billion / ml, which basically reached the standard of insemination. However, the stage body maturity has not yet been completed, so it is not suitable to participate in mating. A small amount of mating can be used in 8-month-old rams, but it is necessary to strengthen breeding. In general, it is best for 1-year-old rams to participate in mating on the premise that their nutritional needs are met. The estrus cycle of small tail Han sheep is 17.2 ±2.17 days, the duration of estrus is 2.66 ±1.15 days, and the duration of first estrus is the shortest. This is related to age and nutritional status. In well-nourished adult ewes, the estrous cycle is short, the days of postpartum estrus is 71.88 ±23.78 days, the first fetus is the longest and the fourth fetus is the shortest. 3. The gestation period of small tail Han sheep during pregnancy was 148.6 ±1.93. there was no significant difference among different parity, and there was little difference among different lambing types. Due to the difference of age and nutritional status, there were some differences, but the difference was not significant. 4. Non-seasonal reproduction is a remarkable characteristic of small-tailed Han sheep. According to the statistics of 170 ewes, 45 ewes were delivered from January to March, accounting for 26.47%, 61 ewes were delivered from April to June, accounting for 35.58%, 23 ewes were delivered from July to September, accounting for 13.53%, and 41 ewes were delivered from October to December, accounting for 24.12%. -and many of them give birth twice a year. According to the statistics of 2101 births from 1964 to 1991, the small-tailed Han sheep is a prolific breed, with an average lambing rate of 281.9% and a maximum of 9 lambs per litter. Its reproductive performance has two remarkable characteristics: first, within the first four births, the lambing rate increases greatly with the increase of parity; second, the third lamb rate and fourth lamb rate of the third and fourth parity are about twice that of the first and second parity, accounting for more than 40% of the number of ewes delivered.
