死亡率，起飞和饲养措施的96个随机选择的用户的社区为基础的动物卫生（BAHS）计划进行了比较，96匹配的部分用户和96个非用户，分别。1997年7月至1999年2月期间，进行了5000多次农场视察，其中3724次视察用于这次评价。进行了单变量和多变量分析，以比较三个用户类别之间的农场特征和牲畜性能。结果表明，与部分使用者和非使用者相比，该方案的使用者拥有更多的反刍动物群和更多的鸡。对于非使用者，小牛（3.2%）、绵羊和山羊（2.8%）和鸡（4.4%）的平均月死亡率是使用者农场（1.4、1.3和2.0%）的两倍，在单变量分析中未显示出显著差异。本研究中监测的所有牲畜物种均显示，在14个月的评估期内，数量有所下降。1997年12月至1998年11月期间，平均年牛出栏量为10.5%（使用者）、9.5%（部分使用者）和7.8%（非使用者），数据变异性很大，使用者类别之间没有显著差异。有大量的牛进出牛栏。这些动物是由各自的农民管理但不拥有的。BAHS方案的使用者比其他任何一个群体更经常地采用某些畜牧业和管理措施。在1999年1月和2月的最后访谈中，与部分使用者和非使用者相比，BAHS使用者对过去一年的牲畜健康和生产情况感到更加积极。总的来说，这项研究的结果表明，在马拉维北方的小农户使用BAHS有助于降低死亡率，从而提高牲畜的产量。(C)2001 Elsevier Science B.V.保留所有权利。
Mortality, off-take and husbandry measures of 96 randomly selected users of a community-based animal health (BAHS) programme were compared with 96 matched part-users and 96 non-users, respectively. More than 5000 farm visits were conducted between July 1997 and February 1999, of which 3724 visits were used for this evaluation. Univariate and multivariable analyses were performed to compare farm characteristics and livestock performance among the three user categories. The results showed that users of the programme owned larger herds of ruminants and more chickens compared to part-users and non-users. For non-users, mean monthly mortalities in calves (3.2%), sheep and goats (2.8%) and chickens (4.4%) were twice as high compared to user farms (1.4, 1.3, and 2.0%) not showing a significant difference in the univariate analysis. All livestock species monitored in this study showed a decline in numbers dining the 14 months period of evaluation. Mean annual cattle off-takes between December 1997 and November 1998 on average were 10.5% (users), 9.5% (part-users) and 7.8% (non-users) with large data variability and no significant differences between user categories. There were large movements of cattle into and out of kraals. These were animals that were managed but not owned by respective farmers. Users of the BAHS programme applied some livestock husbandry and management measures more often than either of the other groups. During concluding interviews in January and February 1999, BAHS-users felt significantly more positive about the past year in terms of livestock health and production compared to part- and non-users. Overall, the results of this study suggested that usage of BAHS by smallholder farmers in northern Malawi contributes towards reduced mortality and thus improved production in livestock.
