Small Tail Han Sheep Selection
Small tailed sheep attract many farmers because of their large size, fast growth, lean meat, and strong reproductive performance. How to select the excellent Small Tail Han sheep is a concern for the purchase and breeding of Small Tail Han sheep. According to our breeding experience at the Xingle Small Tail Han Sheep Breeding Base for several years, we believe that we can select from the following aspects. The selection of production ewes in production, for the production of ewes, we generally require it to have the advantages of strong fertility, maternal strong, that can achieve a year of prolificacy, a production of multiple births, lambs produced by a major birth or significant, mother Goat's milk is full of water and its ability to bring lambs is strong. Therefore, the ewes must take five points. Choose from the physical aspect should choose moderate to large body. In general, larger ewes have larger litter weights or lamb birth weights. The weight of the smaller ewes or the birth weight of the lambs is significantly smaller. Under normal circumstances, the lamb's birth weight is directly proportional to its early growth rate, ie the greater the lamb’s birth weight, the faster its early growth. However, it should be noted that oversized ewes will show lower reproductive capacity for various reasons. From the tail shape, select the tail shape with the characteristics of the variety, that is, square peach (also called fan), but it should be noted that the tail should be thin and small. In general, the large and thick tails are mostly ewes with low production capacity. Their performance is one year of production and one birth. In the group, those who have a long reproductive interval and low productivity. Choose from the mental state should choose active, responsive, fast food intake, eating too much. Most of these ewes have the characteristics of producing a large number of lambs and lambs, and have a strong ability to protect lambs. Avoid mentally depressed, unresponsive, timid and appetite-free people. Most of these sheep are smaller and weaker, and their lambs are not physically strong and have a slow growth rate. Choose from the shape of the breast For the sheep, the breast contraction is good in the early stage of pregnancy, and the late pregnancy shows the breast fullness, thick nipples, and generally have a stronger lactation capacity. Because of their milk, these sheep grow fast and have strong physique. In addition, the eye-eating ewes also have the characteristics of strong lactation. Choose from the appearance of choice should be thin abdominal hair, obvious grass (gastric growth is good, metabolic exuberant); head Qingxiu, straight back, straight, limbs, white hair, or with a small amount of black flowers, half rough sheep (with varieties Features, no serious disqualifications). Avoid ewes with dense hair, large horns, sunken waist, limbs with irregular limbs, variegated spots other than black, and fine hair. Choice of Lambs For lambs, people pay more attention to its growth rate, physical fitness, and the size of the future, so it can be selected from four aspects. Choose from the body shape to choose a lamb with high leg length, strong limbs, wide and thick mouth, large ears and high head and well-shaped body. From the mental state, we must choose the lambs that are bright, bright, lively, responsive, and physically strong. Lambs from 7 to 8 months of age can be selected from the condition of the bedding change, and the lambs can be selected according to the change of lanugo fading (observe the hind legs and wrists to the hocks). Under normal circumstances, if the degree of fetal hair removal is similar, the larger the body grows faster, the closer the body is, the more dense the lanugo grows. When the lanugo is changed, the body is still too small, and most of them are stunted. Select from the appearance to choose the hair close, hair color white hair tenderness (indicating its good nutrition, good development). Should try to avoid the slender and thin lips, small and short ears, dark and long hair, slow and slow response, and bowed back without spirit. When selecting Small Tail Han sheep, if the above points are selected and combined with the characteristics of Small Tail Han sheep, the selected sheep's growth or breeding performance must be at the upper middle level.
