Litter size and litter weight at birth, individual birth weight of progeny, and cumulative body weight (BW) and back fat (BF) gain from insemination until 109 dpc of sows 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) (modified after [4]).

a–cWithin a row, values not sharing a common superscript differ significantly (P<0.05) according to Tukey post hoc test.
1Values are least squares means ± SE per diet over 7 replicates.
2ANOVA PROC GLM, D = diet. Effect of replicate and interaction of diet×replicate were not significant.
