The dietary valine requirement for prolific lactating sows does not exceed
the National Research Council estimate1,2
Two studies were conducted to determine
the effect of increasing the valine:lysine (V:L) ratio
in diets of lactating sows above the minimum proposed
by the NRC (1998). The first experiment involved 189
PIC, Camborough product sows (parity 1 to 4) that were
allotted to 1 of 3 dietary treatments.
