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.
