What are primary factors affecting lamb survival rates?

The primary factors affecting lamb survival rates are indeed birth weight, mother's health, and environmental conditions.

Birth weight is crucial as it influences the lamb's ability to nurse and regulate its body temperature. Low birth weight can lead to weaker lambs that may struggle with survival, especially in adverse conditions. A healthy mother is essential since her nutrition and overall well-being directly impact the vitality of her offspring. If the mother is well-fed and free of disease, she is more likely to have healthy lambs with better chances of survival.

Environmental conditions also play a significant role. Factors such as temperature, shelter availability, and pasture quality can affect lambs' health and growth. For instance, extreme weather can impose stress on both the mother and the lambs, influencing their survival rates.

In summary, the interplay of these elements directly influences the outcome of lamb survival, making them critical factors in sheep management practices.
