Feeding management of various types of sheep
1. Feeding and breeding of rams The breeding of rams should maintain good sensation and enable them to have strong physique, strong sexual desire and good semen quality, so as to better complete the breeding task and bring into play their species. value. The breeding of male rams can be divided into breeding period breeding and non breeding breeding period. The mating period of the diet is roughly: 1 kg of fine material, 2 kg of alfalfa hay or wild grass, 0.5-1.5 kg of carrots, 15-20 g of salt, and 5-10 g of bone meal. All coarse and fine materials can be divided into 2-3 Feeding times. The non-breeding period should be supplemented with 0.5 kg of concentrate, 3 kg of hay, 0.5 kg of carrots, and 5-10 grams of salt. The breeding of rams is mainly based on the combination of grazing and house feeding. The breeding rams are mainly bred during the breeding period, supplemented by grazing. However, exercise should be strengthened, brushing should be done daily, and hooves should be repaired in time. The type of rams should be selected for ventilation, drying, and sunny areas. Each ram needs an area of ​​about 2 square meters, and there must be a wider sports field. Second, the sheep ewes feeding and management ewes responsible for breeding, pregnancy, breast-feeding and other tasks, should maintain a good level of nutrition, so as to achieve multiple births, more productive, more lively, more vigorous purpose. 1. Breeding for pre-breeding: 1.5 months before mating, grasp and rejuvenate, and provide adequate nutrition for breeding and pregnancy. 2. Feeding during pregnancy: The pregnancy period is 150 days. The first 3 months after conception is pre-pregnancy. The early fetus develops slowly and requires less nutrients. As long as the ewe’s body is in good condition, grazing and feeding can meet the needs. In the last 2 months of pregnancy, the fetus grows quickly and gains weight the fastest. This phase requires full-price nutrition and sufficient amounts of nutrients, increasing calcium and phosphorus by 40%-80%, and should not eat moldy, deteriorating feed, drink ice water, and keep the sheep cold. 3, feeding during lactation: breast-feeding period of about 4 months. Two months after birth, the lamb's nutrition depends mainly on breast milk. For every kilogram added to the lamb, it takes about 5 kilograms of breast milk. Normally, each sheep feeds 0.4-0.5 kg of concentrate, 0.7-1 kg of hay, and 1 kg of succulent feed per day. The ability of the ewes to decline gradually in the later period of the milk should be fed with feed concentrate. Within 1-3 days of lambing, if the ewes have good lye, they may not feed concentrate, succulent feed, and silage, but only feed quality hay to prevent indigestion or mastitis. Breastfeeding sheds are often cleaned and kept clean and dry. Tyres, wool, and other dirt should be promptly removed to prevent ewes or lambs from swallowing. Third, the lamb's cultivation Lambs grow fastest, plasticity is greater, the quality of feeding, will directly affect its growth and development at this stage. 1. Colostrum (primary to fifth day) The ewes within 5 days postpartum are called colostrum, which is rich in protein, fat, vitamins and other nutrients and antibodies. Lambs eat colostrum in time after birth, which plays an important role in enhancing physical fitness, fighting disease, and distributing fetuses. The sooner and more colostrum is eaten, the faster the weight gain and the stronger the constitution, the higher the survival rate. 2. During the period of constant milk (6-60 days), milk is the main food for lambs, but it is necessary to eat as early as possible and train forage to promote the development of the forefoot and increase the source of nutrition. Usually, after 10 days, the grass is started and the young hay is tied into the air so that the lamb can freely feed. After 20 days of age, we began to teach feeding. 3, milk and forage transition period (61-92 days), this stage, the lamb food began to milk and forage weight, pay attention to the energy, protein nutrition level and full price of the diet. After the lamb can feed, it is required to diversify the feed and it is best to feed the compound feed. Suggested formulas are as follows: Formula one: corn 50%, wheat bran 20%, rapeseed cake 5%, soybean cake 15%, bone meal 2% 1% of salt, 4% of fishmeal, 2.5% of sugar, and 0.5% of auxin. Formula II: corn 55%, bean cake 32%, bran 2%, lotus root starch 3%, sugar dense 5%, salt 1%, calcium carbonate 0.7%, calcium phosphate 1%, inorganic salt premix 0.3%. Formula 3: corn 48% - 50%, bean cake 30%, barley 10-12%, bran 1.6-4%, lotus root powder 1 - 1.6%, sugar dense 2-3%, salt 0.5%, calcium carbonate 0.8-0.9 %, calcium phosphate 1.8%, inorganic salt premix 0.3%. One month later, as the age of the lamb increases, the lamb is rushed to the pasture to grazing, and the grass is regularly supplied. Maternal and sub-grazing is conducive to gaining weight, grasping and preventing the spread of insects. In order to prevent the occurrence of white muscle disease, 5-6 days old lambs were injected with sodium selenate. The weaned lambs are all dewormed before being transferred or sold. IV. Rearing and management of bred sheep In general, each sheep feeds 200-300 g of mixed concentrate per day. According to the age of male and female ewes and the quality of forage, the amount of concentrate can be adjusted appropriately. Breeding sheep commonly used mixed concentrate formulations: corn 50%, 22% bran, soybean cake 17%, rapeseed cake 60%, urea 1.5%, bone meal 2%, salt 1%, inorganic salt premix 0.5%.
