comparative investigation of rumen urea loading in fistulated lactating Holstein cows: slow release vs. conventional urea

This dataset presents the results of a study designed to investigate the effects of two different urea hydrolysis rates—conventional urea (CU) and slow-release urea (SRU)—on nitrogen utilization in lactating Holstein cows. The study focuses on a comprehensive set of parameters, including blood and milk composition, animal performance metrics, and rumen fermentation characteristics. The dataset provides valuable insights into the physiological and metabolic responses to dietary nitrogen sources in dairy cattle.本数据集呈现了一项研究的成果，该研究旨在探究两种不同尿素水解速率的氮源——常规尿素（conventional urea, CU）与缓释尿素（slow-release urea, SRU）——对泌乳荷斯坦奶牛氮素利用效率的影响。本研究覆盖了多维度综合检测参数，包括血液与乳成分、动物生产性能指标以及瘤胃发酵特性。本数据集可为泌乳奶牛日粮氮源诱导的生理及代谢响应研究提供极具价值的科学参考。
