Basal plasma insulin and glucagon concentrations as well as insulin ratios of sows at 5 days before and 24, 66 and 108 days after insemination.

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).
1Values are least squares means ± SE per diet over 7 replicates. Values in parenthesis indicate numbers of sows within dietary group measured for certain plasma parameters if different from the number of sows generally used per group.
2ANOVA PROC MIXED, D = diet, R = replicate, T = time in days after insemination. D×R = interaction of diet×replicate. D×T = interaction of diet×time.

本试验1（EXP1）中，妊娠母猪全程饲喂三种等能日粮（isoenergetic diets），分别为低蛋白高碳水组（粗蛋白6.5%，LP）、适宜蛋白碳水比组（粗蛋白12.1%，AP）以及高蛋白低碳水组（粗蛋白30%，HP）。
1. 所有数值为7次重复试验中各日粮组的最小二乘均值（least squares means）±标准误（standard error, SE）。若某血浆指标的测定母猪数与每组常规使用的母猪数存在差异，则括号内标注该日粮组内该指标的实际测定母猪数。
2. 采用混合模型方差分析（ANOVA PROC MIXED），其中D代表日粮因素，R代表重复次数，T代表输精后天数；D×R代表日粮与重复次数的交互作用，D×T代表日粮与时间的交互作用。
