Relationship between lactation survival and litter birth weight variation (a, left) or total number born (b, right). The size of the points reflects the number (Nr) of litters included. Lactation survival decreases with increasing litter birth weight variation and litter birth weight variation increases with increasing litter sizes. Hence, larger litter sizes result in less uniform litters and lower survival during lactation.
