Sows were fed isoenergetic diets with low protein∶high carbohydrate (6.5% crude protein, LP), adequate protein∶carbohydrate (12.1% crude protein, AP), and high protein∶low carbohydrate (30% crude protein, HP) ratios throughout pregnancy (EXP1).
Within a row, values not sharing a common superscript differ significantly (P<0.05) according to Tukey post hoc test.
Within diet and variable, values not sharing a common superscript differ significantly (P<0.05) according to Tukey post hoc test.
Values are least squares means ± SE per diet over 7 replicates.
ANOVA PROC MIXED, D = diet, R = replicate, T = time in days after insemination. D×R = interaction of diet×replicate. D×T = interaction of diet×time.
