Precautions for ewes in early pregnancy
2021-05-10
Generally in the practice of
raising sheep, the pregnancy process of the ewe is generally divided into three stages. From conception to about one and a half months (45 days), it is called pre-pregnancy; from one and a half months to three months (90 days), it is called mid-pregnancy; from three months of pregnancy to delivery (140 days), Call it late pregnancy. Ewes have different requirements for feeding management and forage at different stages of pregnancy. Only by meeting the feeding and management methods and forage standards of pregnant ewes at different stages can the healthy development of the fetus and the health of the ewes be guaranteed.
Therefore, whether the ewe is through artificial insemination or natural mating, once the pregnancy is confirmed, six aspects should be started in terms of feeding and management. One is to manage the ewes and other sheep in groups in the early stages of pregnancy, so as to meet the needs of different sheep. The second is to pay attention to adjusting the drinking time. Generally, the drinking time of the ewes in the early pregnancy should be adjusted to after noon. The third is to provide tap water and well water for the sheep, and try to avoid drinking river water and snow water for the sheep, especially water with ice. Fourth, when you go out to graze and drive sheep to exercise, you must reasonably control the movement speed to prevent rapid drive and vigorous running. Fifth, it is necessary to artificially intervene the ewes in and out of the pen in the early stages of pregnancy to prevent squeezing and trampling. Sixth, for the flocks with grazing conditions, the time of grazing must be adjusted in time, and it is best to graze after the sun rises and the temperature rises.
In terms of forage, it is managed from two aspects. One is to increase the feed with higher protein content (pea, bean pod, oil pouring, etc.) in time to meet the healthy development of the fetus. The second is to increase high-quality hay (legume pastures) in time, temporarily not feed or feed less silage, and especially pay attention to prohibit feeding frozen silage that has deteriorated. At the same time, in the use of veterinary drugs, it is necessary to avoid the use of drugs with diarrhea effect and temporarily avoid the use of biological products that are sensitive to sheep's body reactions.
