The main points of improving the survival rate of lambs

The survival rate of lambs is directly related to the economic benefits of the year. When the lambs are well raised, the whole flock can have a good sexual cycle. The experiences and revelations of improving the survival rate of lambs are shared as follows:

First, make sure you eat colostrum in time.

1. Be ready to pick up the lambs. The lambing in March every year is at the turn of winter and spring, and the climate is cold. Due to the poor thermoregulation ability of newborn lambs, heating lamps and other methods should be used to ensure the warmth of the delivery room. Strictly disinfect before using the delivery room and maintain good ventilation.

two。 Make sure you eat colostrum in time. Before feeding the lambs after delivery, wash the ewes' breasts with warm water and ensure that colostrum is eaten within 30 minutes after birth. If you have more than one lamb, you should first weak lamb, lamb, then strong lamb, big lamb, to ensure that each lamb can eat colostrum.

3. Pay attention to the environmental hygiene inside and outside the house. Do a good job in the sanitary management of the sheep house and its surrounding environment. Change the mat grass frequently and keep the sheep shed dry. When a sick lamb is found, it should be isolated in time to prevent the lamb from coming into contact with the sick lamb.

II. Prevention of common diseases in lambs

1. Prevention of leukomyopathy. The ewes during pregnancy were fed with special trace element premix. In sheep farms prone to leukomyopathy, lambs are subcutaneously or intramuscularly injected with 0.2% sodium selenite VE solution 1 ml about 20 days after birth, and 1.5 ml is injected after an interval of 20 days. Pilot projects should be made before use to avoid blind use.

two。 Sheep mouth sores. Pick out the feed with thorns or sharp points in time, provide fine forage for the lambs, and do not graze young sheep in the hard grass area. In the popular season, add an appropriate amount of trace elements and or salt to the sheep. In the areas where the disease is endemic, attenuated sheep mouth ulcer cell lyophilized vaccine can be used every year from February to March. For lambs, it is necessary to strengthen immunization after 3 months. In addition, rinse the lips with 0.1 to 0.2% potassium permanganate solution, and then smear with iodine glycerol for prevention.

3. Lamb dysentery. Ewes were vaccinated with triple tetrad vaccine before or after pregnancy, and sheep after 15 days old were vaccinated with triple tetrad vaccine, no matter how big or small they were, each sheep was vaccinated with 1.0ml twice a year. Lambs can be given oxytetracycline and pepsin twice a day for prevention. 4. Sheep infectious pleuropneumonia. Keep the sheep shed ventilated, dry, warm and clean; pay attention to weather changes, reduce stress, prevent cold and warm in winter and spring, prevent wind and rain after sweat in summer, inactivated vaccine against infectious pleuropneumonia in goats, injected subcutaneously or intramuscularly on the cervical side; inactivated vaccine against Mycoplasma pneumoniae in sheep, subcutaneously or intramuscularly on the cervical side.
