Quiniou et al2 reported that pigs weighing
< 1 kg at birth had very little chance of
being alive at weaning. Similarly, Gondret
et al3 found that 86% of piglets weighing
< 0.80 kg did not survive to weaning.
Gardner et al10 divided birth weights
into nine groups ranging from < 601 g
to > 2000 g. They reported that increases
in birth-weight category were associated
with increasing odds of 7-day and 21-day
survival, with maximum survival in the
highest birth-weight group.
