我发现在畜群营养调查中有用的生物学试验是瘤胃pH值、血清β-羟基丁酸（BHBA）、血浆非酯化脂肪酸（NEFA）、尿液pH值和牛奶或血液尿素氮（UN）。生物学测试在评估营养管理、口粮配方或疾病发生率中发现的问题时非常有用。然而，由于样本量、样本处理、相对于喂养的采集时间和实验室误差，它们会出现误差。因此，生物学试验结果通常不是独立的，而是应该得到畜群调查的其他数据的支持。
Biological tests that I have found useful in herd nutritional investigations are ruminal pH, serum beta-hydroxybutyric acid (BHBA), plasma non-esterified fatty acids (NEFA), urinary pH, and milk or blood urea nitrogen (UN). Biological tests can be very useful in assessing problems found in nutritional management, ration formulation, or disease incidence. However, they are subject to error due to sample size, sample handling, time of collection relative to feeding, and laboratory error. Thus, biological test results generally do not stand alone, but should be supported by other data from the herd investigation.
