Causes of high mortality of lambs and preventive measures

At present, the market price of mutton is still relatively high, and the market demand is only increasing, which attracts many people to start raising sheep, but farmers have found that the mortality rate of lambs is relatively high. So what caused it at this time? How to prevent it? Let's get to know it.

1. Insufficient lactation of ewes

If the lamb is not late for sufficient breast milk in time after birth, it will affect the physique and health of the lamb, resulting in a large number of casualties, which is mainly related to the insufficient lactation of ewes, and there are two main reasons for insufficient lactation of ewes. One is the lack of nutrition and drinking water, and the other is that the ewe suffering from mastitis affects normal lactation.

Preventive measures: ewes should check whether they suffer from mastitis and unobstructed chicken nipples. Under normal circumstances, ewes can be fed with some bean cake soup to appropriately increase the amount of green succulent feed such as grass and carrots, and to prevent mastitis. Keep the sheep house clean after delivery, regularly clean the breasts with hot towels and disinfect the nipples with iodophor, and isolate the lambs in time if they suffer from labor costs. Use drug treatment, and then breast-feed the lambs later, at this stage, the lambs can be farmed.

2. Malnutrition of ewes

More than 80% of the birth weight of the lamb is obtained in the middle and late pregnancy of the ew. if the nutrition intake of the ewe in the middle and late pregnancy can not meet the needs of their own consumption and the growth and development of the lamb, the physique of the lamb will be weak. And malnutrition will also affect the postpartum lactation ability of ewes. If there are too many lambs, it is very easy for the lambs to die.

Preventive measures: in the middle and later stages of pregnancy, ewes need to appropriately increase the supply of nutrition, the first thing is to increase the amount of concentrate feeding, the proportion of concentrate in the diet should be more than 15%, and the proportion of concentrate in the diet of high-yield ewes should be more than 20%. It is to pay attention to the supplement of minerals, trace elements and vitamins in the feed, and the third is to increase the exercise and lighting time of ewes to promote digestion and nutrition accumulation.

3. Lamb paralysis

Lamb paralysis has become one of the high incidence diseases in sheep industry in recent years, which mainly occurs in lambs less than one month old. Lambs with better fat condition are more likely to get sick, sick lambs suddenly fall ill, unable to lie on the ground, weak, unable to breastfeed, dyspepsia, and undigested milk in the stomach.

Preventive measures: ewes in the middle and later stages of pregnancy must strengthen feeding management, appropriately increase the amount of exercise and green succulent feed, so that ewes and lambs can have a good physique. The heat preservation material should be made after the lamb is born, and the nutrition level of the feed should be properly reduced when the mother's milk is thick, but the intake of green succulent feed should be ensured. After the lamb has symptoms of soft paralysis, the lamb can be injected intramuscularly with 2 ml of compound vitamin B injection. Oral pepsin tablets 5: 10, twice a day, after 3 days, most lambs can get better.
