The reason for the low survival rate of lambs

The main results are as follows: 1. Milk supplement is random, lambs are in a state of semi-hunger for a long time, and it is common for farmers to raise ewes in a state of postpartum physical weakness and delayed lactation; ewes give birth or ewe mating age is too early, breast development is poor; ewes' postpartum illness can not be treated in time. Some high-yield ewes give birth to too many lambs at one birth and some farmers ignore the feeding and management of lambs, resulting in random replenishment of milk, lambs in a state of semi-hunger for a long time, resulting in a weak physique. In the event of illness or sudden change in the weather, lambs are prone to freeze and starve to death.

2. The mixed grazing of lambs and adult sheep leads to the increase of accidents. Due to the limitation of conditions, there is no independent lamb pen; there is lack of cold protection and heat preservation measures during lambing in late autumn, winter and early spring cold seasons; separate lamb flocks are not organized, and some lambs that can only initially adapt to grazing are grazed far away with large flocks. Due to the mixed grazing of lambs and adult sheep, the forage and concentrate of lactating ewes and lambs are robbed by other sheep; crowding, deterioration of sanitary conditions, low temperature, humidity, distant grazing and so on, all affect and threaten the health of parturient ewes, lactating ewes and young lambs. At the same time, the feeding environment of mixed grazing of adult sheep and lambs has also created conditions for the occurrence and spread of some diseases.

3. it is not timely to replenish grass and feed, which leads to the fattening phenomenon of lambs. Some farmers rely too much on grazing for food. Entering the dry grass season in winter and spring, with the increase of lamb weight and growth rate, the demand for nutrients of lambs will gradually increase, some lambs are still in the weaning period, simple grazing alone can not meet the needs of lamb growth and development. If the forage feed is insufficient, the grass filling is not timely, or the lamb is mixed with the adult sheep, and the forage feed fed to the lamb is looted by other adult sheep and strong sheep, it will cause the lambs to lose fat generally, such as wind, rain (snow) weather. It is easy to endanger the lives of some weak, young and sick sheep.
