Abstract：
Herd health management is a planned program to optimize health, welfare, and production of dairy cows. A cross-sectional study focused on herd health management of dairy farms, was carried out to assess the biosecurity, health, and disease management practices with associated socio-demographic factors. A structured questionnaire with closed- and open-ended questions was employed for farmers\' interviews to acquire information on dairy farms. Data were collected from randomly selected 205 dairy farms in five districts (Dhaka-Savar, Mymensingh, Gazipur, Rangpur, and Sirajganj) of Bangladesh. Overall, 1.5% farms had \"good\", 17% had \"moderate\" and 81.5% had \"poor\" levels of biosecurity, health and disease management practices (BHDMP). Analysis of variance revealed that mean BHDMP scores were significantly (p < 0.05) higher in farms of Rangpur (27.6 ± 0.8) and Gazipur (26.7 ± 0.6) than those of the other three districts. Educational status had a significant effect on BHDMP scores. The farms owned by graduated farmers had the highest mean BHDMP score (30.4 ± 1.1) while the farms operated by illiterate farmers had the lowest BHDMP score (20.4 ± 0.4). Multiple linear regression analysis also revealed that educational status (secondary to post-graduation), training experience, area of study (Rangpur district), and herd size were significantly associated with BHDMP score of the farms. The findings lay a basis for improving dairy farms\' biosecurity, health and disease management practices, which further envisage the adoption and implementation of herd health management programs.
摘要：
牧群健康管理是一项有计划的计划，旨在优化健康，福利,和奶牛的生产。一项针对奶牛场羊群健康管理的横断面研究，是为了评估生物安全，健康,以及与社会人口因素相关的疾病管理实践。采用带有封闭式和开放式问题的结构化问卷进行农民访谈，以获取有关奶牛场的信息。数据是从五个地区（达卡-萨瓦尔，Mymensingh,Gazipur,Rangpur,和孟加拉国的Sirajganj）。总的来说,1.5%的农场有“良好”，17%的人有“中等”的生物安全水平，81.5%的人有“差”的生物安全水平，健康和疾病管理实践(BHDMP)。方差分析显示，Rangpur（27.6±0.8）和Gazipur（26.7±0.6）的农场的平均BHDMP得分显着（p<0.05）高于其他三个地区。教育状况对BHDMP成绩有显著影响。毕业农民拥有的农场的平均BHDMP得分最高（30.4±1.1），而文盲农民经营的农场的BHDMP得分最低（20.4±0.4）。多元线性回归分析还显示，教育状况(中学到毕业后)，培训经验,研究领域(朗普尔区)，和牛群大小与农场的BHDMP得分显著相关。这些发现为改善奶牛场的生物安全奠定了基础，健康和疾病管理实践，进一步设想采用和实施畜群健康管理方案。
