Grasping variety breeding Fertility is heritable, and the fertility of different breeds is also different. Two or three births a year are produced, but most breeds produce 2 to 3 lambs, and individual lambs can reach 4 to 8 lambs. Therefore, to improve fecundity, it is necessary to introduce prolific characteristics in hybrid improvement, or to select prolific mutations to fundamentally improve the performance of herds, and to establish a sound breeding registration system and improved breeding system. Picking good breed sheep The excellent sheep are in good condition, energetic, short and thick round neck, strong in physique, rectangular in shape, wide in chest, flat in back, long and wide in hips, moderate in testicle size, symmetrical in symmetry, and relatively open to the base of scrotum. Far, the quality of semen is good. Any sheep that is deformed in the testosterone, cryptorchidism and any genital organs cannot be used for breeding. The species of ewes should be large in size, compact in size, plump in muscle, elastic in skin, wide in chest, straight in back, slightly larger in posterior abdomen, with straight limbs, wide spacing, rapid growth and development, high meat yield, and lamb production. More, the breasts are soft and spherical, have good lactation performance, are dexterous, lively and lively, walk briskly, have high heads, and have a shiny coat. Optimize the flock structure Female goats generally do not exceed 7 to 8 years old, and the overall structure ratio of the sheep is 47% for educable ewes, 50% for ewes and sheep born in the same year, and 3% for rams. In addition, in addition to replacing male rams every year to prevent inbreeding, we must also strengthen the elimination of old sheep, diseased sheep, weak sheep, and perennial infertile sheep so as to ensure that the age-appropriate sheep account for more than 70% of the total number of sheep. ,high yield. Strengthen feeding management Spring: The weather is cold and changeable, and it is a lambing season. Ewes are heavy and have weak constitutions. When grazing, we must control the sheep, require strong and weak, run less, and eat more grass. Summer: There are many days of hot mosquitoes. Grasping the grazing in the morning and evening will create a cool environment for the sheep. Try to extend your time and allow the sheep to eat more grass. Fall: When grazing, it is necessary to change the grass frequently, choose where the grass seeds are to be grazing, and urge the sheep to accumulate more fat and lay the foundation for breeding and wintering. Winter: Most ewes are in late pregnancy, and the climate is cold, so the grazing should be secure, and the amount of exercise is appropriate. Conditional farm owners should properly add some quality hay and concentrates. Our mission: To protect the health of ear, throat and nose with medical frontier knowledge and technological innovation.
