A partial budget model was developed to evaluate the economic value of Rumensin Controlled Release Capsule (CRC) boluses when administered before calving to reduce disease and increase milk production. After accounting for disease incidences in a herd and the percentage by which Rumensin CRC can reduce them, and the increase in milk production attributable to administration of Rumensin CRC, the return on investment (ROI) per lactation was 4:1. Another partial budget model was developed to estimate the economic value of propylene glycol (PG) to treat ketosis when diagnosed by 3 different cow-side tests or when administered to all cows without using any cow-side testing. After accounting for the sensitivity and specificity of each test, ROI per lactation ranged from 2:1 to 4:1. The ROI was 2:1 when no cow-side testing was used. In conclusion, prevention of diseases that occur in the postpartum period and treatment of ketosis after calving yielded a positive ROI that varies based on disease incidence and method of diagnosis.
开发了一个局部预算模型，以评估在产犊前投喂瘤胃素控释胶囊（CRC）丸剂以减少疾病并提高产奶量时的经济价值。在考虑了牛群中的疾病发生率以及瘤胃素CRC可降低疾病发生率的百分比，以及投喂瘤胃素CRC后产奶量的增加后，每个泌乳期的投资回报率（ROI）为4:1。还开发了另一个局部预算模型，以估计丙二醇（PG）在通过3种不同的现场奶牛检测诊断为酮病时或在不使用任何现场奶牛检测的情况下投喂给所有奶牛时治疗酮病的经济价值。在考虑了每种检测的敏感性和特异性后，每个泌乳期的投资回报率在2:1至4:1之间。当不使用现场奶牛检测时，投资回报率为2:1。总之，预防产后发生的疾病以及产犊后治疗酮病产生了正的投资回报率，该回报率因疾病发生率和诊断方法而异。
