这项研究旨在对公共环境中水牛的健康和生产力进行概况分析。使用Epi-Info版本6.04进行数据管理，使用编码信息系统来容纳来自参考人群的数据。分别对出生和挤奶的小牛和奶牛进行了6个月的登记和监测。本研究监测的主要结果包括死亡率、发病率和生产率。研究结果显示，犊牛存活6个月的概率为93.7%，计算出的真实死亡率为每1000个犊牛日死亡0.7人。在6个月的观察期内，有3头小牛死亡，平均死亡年龄为3天。产率方差分析表明，寄生负荷，特别是球虫、肝吸虫和锥虫影响犊牛的生长速度。本研究奶牛的产奶能力也受到动物体内寄生虫负荷和疾病状况的高度影响。单因素分析显示，小牛冲刷与奶牛乳腺炎（mastitis）之间存在显著相关性（P=0.066）。同时，对奶牛而言，寄生负荷尤其是片形虫病（P=0.000）、球虫病（P=0.002）和锥虫病（P=0.094） （P < 0.10）也显著影响产奶量。研究结果对这些动物的健康和生产力之间的关系有了更清晰的认识。
This study aimed to generate a profile of the health and productivity of water buffaloes in a communal setting. Using the Epi-Info version 6.04 for data management, a coded information system was used to accommodate data coming from the reference population. Calves and cows that were born and milked, respectively, were enrolled and monitored for six months. The key outcomes of interest monitored in this study included mortality, morbidity and productivity. Results of the study showed a 93.7 percent probability of the calves surviving up to six months with a calculated mortality true rate of 0.7 deaths per 1000 calf-days at risk. Three calves died during the six month observation period with a mean age at death of 3 days. Analysis of variance on productivity showed that the parasitic load, specifically coccidia, liver fluke and trypanosoma affected the growth rate of the calves. The productivity of cows in the study in terms of milk production was also highly affected by the endoparasitic load and disease condition of the animal. Univariate analysis revealed a significant association between calf scouring and cow's mastitis (MASTITIS)(P=0.066). Meanwhile, for the cows, the parasitic load particularly fasciolosis (P=0.000), coccidiosis (P=0.002) and trypanosomosis (P=0.094) (P < 0.10) also significantly affected the milk production. The results give a clearer view of the relationship between the health and productivity profiles of these animals.
