One species of ewes
1. Before breeding and mating, it is necessary to do a good job of rejuvenation and reserve nutrition for mating. The grain is based on maintaining normal metabolism. After weaning, leaner ewes should be appropriately increased in nutrition to achieve recultivation purposes. The daily feed is mainly dry roughage, such as sweet potato vines, peanut stalks, etc., allowing them to freely feed, grazing for about 4 hours a day, during this period each supplement of each day is about 0.4 kg of mixed concentrate.
2. During the first trimester of pregnancy, the fetus develops slowly, and the nutritional needs are basically the same as the empty period. In the second trimester of pregnancy, the fetus develops rapidly, and 80% of body weight grows during these two months. Therefore, there should be adequate, full-priced nutrition, the metabolic level should be increased by 15 to 20% on the basis of the pre-pregnancy, calcium, phosphorus content should be increased by 40 to 50%, and there is sufficient vitamin A and vitamin D, every day Only 0.6 to 0.8 kg of mixed concentrate should be supplemented, and 3 to 5 grams of bone meal should be supplemented every day. Some succulent feed should be fed about 10 days before delivery. In addition, management should be strengthened to prevent crowding and frightening crowds. The daily activities should be dominated by “slow and steady†and must not eat mild feed and frozen feed to prevent abortion.
3. Feeding during lactation is 2 to 3 months postpartum for lactation. Within 2 months after delivery, breastmilk is an important nutrient for lambs and nutrient supply to the ewes should be guaranteed. In general, each ewlet feeds 1 to 2 kilograms of succulent feed daily and 0.6 to 1.0 kilograms of concentrate. The management of nursing ewes should pay attention to controlling the amount of concentrates. In 1 to 3 days after delivery, ewes cannot feed too much concentrate and can not feed cold or ice water. When lambs feed on feeds before weaning, the amount of mutton succulent feed and concentrate should be gradually reduced to prevent breast disease. The ewe's house should be cleaned and disinfected regularly, and dirt such as the placenta and hairballs should be promptly removed to prevent the lambs from swallowing the disease. Lambs are generally weaned until about 2 months of age.
Second, the kinds of rams Rams play an important role in raising the productivity of the flock and improving the low-yield sheep, must be strictly feeding and management, in order to maintain the strong ram bred physique, good sensation, strong sexual desire, good semen quality, quantity and more.
1. Nutritional requirements Male ram feed requirements are higher, there must be sufficient quality of protein, vitamin A, vitamin D and inorganic salts, and easy to digest, good palatability, preferably from bran, soybean meal, carrots, malt and other mixed Made. Animal protein is very important for rams. When the frequency of breeding or picking is high, raw eggs and milk must be supplemented.
2. Use rams for management and keep them in a single lap. Do not put them together with ewes at other times, except for breeding. Rams should be grazing and exercising in groups of 4 to 6 hours per day. The breeding season is usually 1 to 3 times a day, continuous collection of sperm 3 to 4 days off a day. After quietly picking, let it rest for a while, especially hot in summer and cold in winter. Ram's semen quality is poor, so it is not appropriate to collect sperm. The rams must also undergo regular quarantine, prevent vaccination and control of parasites in the body and the outside, and pay attention to observe the mental state of the rams in a routine manner and find problems in a timely manner.
