Practical approaches to increase whole milk total solids: effects on performance and health of dairy calves

This Supplementary Material is part of the manuscript "Practical approaches to increase whole milk total solids: effects on performance and health of dairy calves". This study aimed to evaluate the performance, metabolism, and health of Holstein calves fed whole milk adjusted for 15% total solids by adding a commercial solids corrector (24% crude protein and 4.8% crude fat) using two practical approaches: daily adjustment using a Brix refractometer or the addition of a fixed amount of the corrector based on mean milk solids content.

本补充材料隶属于学术论文《提升全乳总固体含量的实用方法：对荷斯坦犊牛（Holstein calves）生产性能与健康的影响》。本研究旨在评估两种实用方案下，向全乳中添加商用固体校正剂（粗蛋白含量24%、粗脂肪含量4.8%）将全乳总固体含量调整至15%后，饲喂荷斯坦犊牛的生产性能、代谢状态与健康水平。两种方案分别为：采用糖度折射仪（Brix refractometer）每日进行校正调整，或是基于平均乳固体含量固定添加校正剂用量。
