Feeding technology for mutton sheep
1. Breeding ewes feeding technology The ewes are responsible for the heavy tasks of breeding, gestation, and breastfeeding. They should be given good husbandry to ensure multiple births, prolificacy, more living, and more prosperous growth. Breeding ewes are divided into empty period, gestation period and lactation period according to physiological stages. The empty period refers to the period from the weaning of the lamb to the breeding of the ewes again, and also to the recovery period, about 3 months. During this period, the focus of ewes rearing is to rejuvenate and rejuvenate, and the body condition is restored to medium or above, so as to facilitate breeding. In the first condition, the pregnancies can reach 80% to 85% in the first condition and only 65% ​​to 75% in the poor condition. Strengthen the ewes breeding one and a half months before, try to choose a good grassland grazing, extend the grazing time, such as poor grassland grass, when they are not enough, each sheep daily feed 0.2 ~ 0.3 kg of mixed concentrate , To achieve more than moderate levels of nutrition, in order to promote estrus, so that the heat and tidy, improve the conception rate and double lambs rate. The gestation period of ewes during pregnancy is 5 months. The first 3 months are pre-pregnancy and the latter 2 months are late pregnancy. In the early pregnancy, the fetus develops slowly in the mother and only occupies 10% to 20% of the birth weight. The ewe can maintain the body weight before mating. This period coincides with autumn, which is a grass seeding period with rich nutrition. Grazing can meet the nutritional needs of ewes without supplementation. In late pregnancy, the fetus grows and develops faster in the mother's body. About 80% to 90% of the fetus's body weight is formed in the latter part of pregnancy. It needs to be supplied with higher nutrition. If the nutrition is insufficient, the lamb's birth weight is small, the survival rate is low, and the ewes' lactation capacity is low. decline. At this time, the ewes nutrition, the energy than the empty period increased by 30% to 40%, protein increased by 40% to 60%, calcium scale increased 1 to 2 times, vitamin increased 2 times. In addition to grazing, feed 0.5–1 kg of wild hay; 1 kg of silage; 0.5–1 kg of concentrate; 52% corn, 25% soybean cake, 18% bran, salt, stone meal, bone meal, baking soda , Premix 1% each. Breastfeeding during lactation is 2.5 to 3 months. After lambs are born, the ewes should drink some warm salt water or add some bran in warm salt water to regulate the digestive function and promote the discharge of lochia. Ewes can only feed some high quality hay within 3 days after delivery, and do not feed concentrates and juicy materials to avoid indigestion or mastitis. After 3 days, they can feed a small amount of mixed concentrates and juicy ingredients and gradually reach breast-feeding. Period of the amount of feed. After lambing, lactation levels gradually increased, peaked at 4 to 6 weeks, and began to decline after 10 weeks. Lambs produced 20 days of nutrition entirely dependent on breast milk supply. The first 1.5 months after lambing is the pre-lactation period. The ewes are raised on a standard of 1.5 kg of wild hay, 1 kg of silage, 0.5 kg of carrots, and 1 to 1.5 kg of mixed concentrate (52% of corn, 18% of bran and 25% of bean cake). 1% for salt, baking soda, rock meal, bone meal, and premix. After 1.5 months for the late lactation period, ewes feeding standards: 1 to 1.5 kg of wild hay, 1 kg of silage, 0.5 kg of carrots, and 0.5 to 1 kg of mixed concentrates; II. Breeding sheep rearing techniques for bred sheep means from weaning to The first maternal and maternal juvenile sheep (3 to 18 months of age), after 3 to 4 months after weaning, have a fast growth and a large weight gain, and require high feeding conditions. However, this stage is often overlooked. The weaning is done on the basis of the fact that the material is cut off and no feeding is done during the weedy period, resulting in malnutrition. The body is weak, the body is narrow and shallow, and the species value is lost. After the weaning of the lambs, it is the lambs that have been most productive during the period of weaning. However, the function of the rumen is still not perfect. The utilization rate of roughage is low, and the diet is mainly concentrated, and the quality hay and silage juicy materials are supplied. The mixed concentrates were fed with 0.2-0.3 kg per day (corn 50%, soybean cake 25%, rice bran 20%, stone powder, salt, bone meal, baking soda, premix 1% each). By June, the pasture has good quality grass, and the sheep can only eat 3 to 40% of the full time per day without supplementation. The rearing technology of the late breeding period is in the period of withered grass and the weather is cold. It is also during the development of the ewes and maintains the consumption of physical energy. It is necessary to strengthen the supplementary feeding, each feeding 1 kg of wild hay, 1 kg of silage and 0.5 kg of carrots. Mixing concentrate 0.4-0.7 kg (corn 55%, bean cake 20%, bran 20%, salt, stone powder, bone meal, baking soda, premix 1%). III. Lamb feeding techniques Lambs are young sheep from birth to weaning (lactating). Generally weaning at 2 to 3 months of age, but also according to the lamb's body weight discretion, generally weighing more than 20 kilograms. After the lamb is born, it has a weak constitution, low resistance, poor adaptability and easy to get sick. Doing a good job in lambs is the key to improving the survival rate of lambs. Eat early and eat good colostrums should eat colostrum within 1.5 hours after birth. Colostrum is rich in protein, magnesium and antibodies. Magnesium has a laxative effect, promotes rapid excretion of the fetus and enhances the body's immunity. After the lamb is born, it can stand and walk about 10 minutes to find a nipple. When the frail lamb cannot find the ewes' nipples, they should artificially hold the lambs to the ewes to induce their milk. After 20 days of eating, the regular milk lambs will have a 1 hour feeding time. After 20 days, they will have an interval of 4 hours. As the age increases, the number of feedings decreases, the interval increases, and the duration of each feeding increases relatively. For lambs who have lost their mothers or mothers without milk or enough milk to eat, seek lambs for lambs. Can also be artificially supplemented milk, milk must be sterilized after 70 °C to drink, so that timing, constant temperature, quantitative, temperature 38 ~ 42 °C is appropriate. Within 7 days postpartum, feed once per hour, then gradually change to 8 times a day, and keep feeding every 4 hours after 20 days. Lambs born throughout the day generally have 1/5th of the birth weight, and the amount of feed every other week increases by 1/4 to 1/3. Early feeding and feeding the lambs should be trained for eating and eating 7 to 10 days after birth. Hang the grass to attract the lambs and use the saute to induce the lamb to eat. From the 15th to the 20th day after the lamb is born, the lamb is supplemented with a mixed concentrate, preferably 50 grams per day per lamb, and the amount of the supplemented concentrate is gradually increased as the lamb grows and the nutrient required is gradually increased. Once every 5 to 7 days, once the lamb's age reaches 60 days, the total amount of mixed concentrates supplemented should reach 300-350 grams. Lamb supplements and concentrates formula: corn 50%, bran 15%, bean cake 30%, salt, stone powder, bone meal, baking soda, premix 1% each.
