Ewes need to pay attention to during pregnancy:

1. In the first 3 months of pregnancy (the early period of pregnancy), the fetus of ewes develops slowly and does not require much nutrients. In addition to grazing, a small amount of supplementary feeding is required depending on the pasture conditions, and the ewes are required to maintain good fat storage. In terms of management, it is necessary to avoid eating frost grass or moldy feed, not making the ewes run away in fear, and not drinking ice water.

2. Pay attention to the hygiene of the sheep pen and keep it ventilated and dry to avoid the occurrence of infectious diseases.

3. Usually, lambs need to eat colostrum immediately when they are born. If the ewe is thin and has no milk, it is necessary to find another ewe to breastfeed, or to artificially breastfeed.
