1. Postpartum ewes care
After the ewes are born, their bodies are weak, they should be allowed to rest, and they should be given some warm saline water; they should be fed bran and hay. Fetal clothing is usually discharged 2-3 hours after childbirth and should be removed in time to prevent ewes swallowing. The sheep should cut off the hair around the breast and teach the ewes to protect the lamb and give milk.
The nutrition of lambs during lactation depends mainly on the ewes. Breast milk is the main source of nutrition for the growth and development of lambs. Ewes and lambs are good for growth and development, with strong resistance to disease and high survival rate. Therefore, ewes should be supplemented 1 to 3 days after childbirth. The supplementary feeding of ewes must be based on local specific conditions to supplement the supply of juicy and high-quality hay, supplement the feed properly, and 0.25 to 0.5 kg of supplements per ewe per day. Common feed formulations such as corn Powder 35%, wheat bran 47%, beancake or vegetable (cotton) seed cake 15%, salt 0.5%, and mineral premix 2.5%; or corn flour 54.0%, wheat bran 27.0 %, 8.0% black beans, 8.0% soybean cake, 1.0% bone meal, 1.0% aluminum dihydrogen phosphate, 1.0% salt.
Ewes 1 to 3 days after childbirth, can not be fed too much concentrate to prevent indigestion and mastitis; ewe can not drink cold water and ice water soon after birth; when the lamb is weaned, it is also necessary to reduce the ewes Feed, silage and concentrate feeds.
2. Lamb Care
(1) The auxiliary lamb eats colostrum. Colostrum is thick, nutritious, and contains the antibodies, antioxidants, and enzymes required for newborn lambs. Lambs eat colostrum to promote the discharge of meconium and enhance the resistance of the disease. Lambs can walk and eat milk 1 hour after they are born. If they cannot feed themselves, they should be assisted by the confinement staff to ensure that the lambs eat colostrum.
(2) Lamb feeding. The lamb's lactation period is generally 2 to 3 months. The ewe's milk volume is gradually reduced after 1 month of delivery, and it is often unable to meet the needs of the lamb's growth and development. Therefore, 10-15 days after birth, the lamb should train its ability to feed. First, let the lamb learn to eat forage leaves, or choose high-quality, soft grass and legume grass, tie into a small 5 cm diameter grass, hanging in the sheep house for 4 weeks, let it feed; 30-day-old lamb To allow them to eat mixed concentrates, each 50 to 100 grams per day, 60-day-old lambs from 100 to 150 grams. The supplemented salt and bone meal can be mixed into the concentrate and fed.
(3) The castration of the lamb. A lamb that is not suitable for breeding can be castrated within 15 to 30 days after birth. After castration is easier to manage, easy fattening. If the early fattening sale is not castration.
(4) Weaning and grouping of lambs. After 30 days of age, the physiological function of the digestive tract of the lamb gradually improved, gradually changing from the breast-feeding to the feeding of forage; after 60 days of age, the pre-stomach of the lamb is mature and its function is basically the same as that of the adult sheep. At this time, the lamb can be weaned. Now. Determine the lamb's weaning time to consider: body weight up to 2.5 times the birth weight, dry feed intake feed more than 30 grams. Usually weaned 42 to 84 days of age. Lambs are reared in groups after weaning, with strong and weak males and females.
(5) Prevention of lamb disease. There are two kinds of diseases that can easily occur in lambs. One is Lamb dysentery and the other is pneumonia. Lamb dysentery is caused mainly by infection with Escherichia coli, Salmonella, and Clostridium welchii. Generally, after 2-4 days of birth, lambs appear diarrhea, feces appear pale, pale yellow or green, and are affixed near the anus, with special smelly feeding. There is also blood in the feces. Lamb spirit, loss of appetite, ear, nose and limbs cold back arch, neck flexion, head and body weakness, the mortality rate of this disease is high, should pay attention to prevention and timely treatment. In sheep farms where lamb diarrhea has occurred, in order to prevent them, injectable vaccines or continuous penicillin tablets (50,000 units/tablet) are given to the lambs once a day for 1 to 2 tablets for 4 to 5 days. Individual lambs appear diarrhea, you can inject 125,000 units of chloramphenicol, 2 or 3 times a day; you can also use chlortetracycline 20 to 40 mg, sodium glycinate 2 to 4 mg dissolved after intravenous injection; you can also use sulfamethoxazole 0 .5 grams, 0.2 grams of sodium hyponitrite, 0.2 grams of tannic acid protein, 0.2 grams of baking soda, and appropriate amount of water, once every 8 hours, once every 2 to 3 days. Pneumonia is mainly caused by the fact that the climate has become colder or the sheep house is too moist and carbon dioxide gas cannot be discharged in time. Suffering from forced breathing, coughing, wheezing, runny nose, increased body temperature and no appetite. Treatment can be injected 100,000 units of penicillin, injected twice a day; can also take sulfathiazole,; the first feed 2 grams, after each l grams, 3 times a day, and even served 3-4 days. Prevention of white muscle disease can be taken from the material, oral sodium sulfite 3 to 5 mg, every 7 days and then once again; to prevent intestinal diseases, can drink 0.1% potassium permanganate water once a week; to prevent outside the body The infection and spread of parasites are prophylactically deterred each spring and fall.
