Abstract
The maternal weigh-suckle-weigh (WSW) method for estimating milk production of sows was further evaluated by comparing this to the traditional WSW method. Twenty one estimates of hourly milk production were obtained by both methods. Total hourly milk production between the two methods was not significantly different (292.4 vs 303.3 g/h, p > 0.05). Hourly milk production determined by the maternal WSW method was highly correlated with hourly milk production estimates using the traditional WSW method (
