The cashmere goats' estrus is mainly in spring and autumn and autumn is the focus. The symptoms of estrus are loss of appetite, irritability, redness in the vulva, swelling of the vulva, mucus, frequent tailing, trailing of the ram, or crawling across Other ewes. When the ram approaches, the ram does not move, and the ram spreads when the hind limbs are separated. Accept the mating. Goat's estrus duration is 24 hours to 48 hours, and ovulation usually begins 30 to 40 hours after the onset of estrus. The timing of timely breeding should be 12 to 24 hours after estrus. Ewes can preliminarily think that they have become pregnant if they have not experienced another estrus after 1 – 2 months after mating. After two months, you can use the check method to confirm if you are pregnant. Pregnancy tests are generally performed in the morning when the fasting is carried out. The examiner clips the head and neck of the ewes between the two legs and bends down to place both hands on the front of the lower uterine udder in front of the ewes, pulling the abdomen slightly, and the left hand to the right of the sheep. The abdomen pushed slightly to the left. The index finger of the left thumb can touch the fetus. After 60 days, a harder piece can be touched; the fetus of 90 days to 120 days can touch the ribs of the hind legs, and the ribs of the hind leg are softened and hardened with the increase of the age of the month. When there is a hard mass in the abdomen, the fetus only has one; if there is a hard mass on each side, it is a twin lamb; when there is a hard mass behind the chest, it is a lamb. When checking, hand should be light and flexible. Carefully touch all parts and must not be careless, resulting in miscarriage of the ewes. Accurately grasp the estrus period, conduct timely mating, make a pregnancy check, and supplement the ewes according to their pregnancies to prepare for the successful lamb production.
