Supplemental Table S2. Least square means of BW, DMI, milk yield (MY) and fat- and protein-corrected milk yield (FPCMY), milk protein yield (MPY), milk composition (milk fat, milk protein, milk lactose and MUN), milk N efficiency (MNE) and feed efficiency for the CTRL, MetLys and MetLysHis treatment groups in the pre-experimental, depletion and cross-back period.

<strong>Supplemental Table S2.</strong> Least square means of BW, DMI, milk yield (MY) and fat- and protein-corrected milk yield (FPCMY), milk protein yield (MPY), milk composition (milk fat, milk protein, milk lactose and MUN), milk N efficiency (MNE) and feed efficiency for the CTRL, MetLys and MetLysHis treatment groups in the pre-experimental, depletion and cross-back period.补充表S2。本补充表列出了对照组（CTRL）、蛋氨酸赖氨酸组（MetLys）与蛋氨酸赖氨酸组氨酸组（MetLysHis）在预试验期、耗竭期及交叉回溯期的体重（Body Weight, BW）、干物质采食量（Dry Matter Intake, DMI）、产奶量（milk yield, MY）、乳脂乳蛋白校正产奶量（fat- and protein-corrected milk yield, FPCMY）、乳蛋白产量（milk protein yield, MPY）、乳成分（乳脂、乳蛋白、乳糖及牛奶尿素氮（milk urea nitrogen, MUN））、乳氮效率（milk N efficiency, MNE）与饲料效率的最小二乘均值。
