A federal and provincial cost-shared program was initiated in 2001 around Riding Mountain National Park in southwestern Manitoba, Canada to provide free game wire barrier fences for baled hay storage areas to prevent transmission of TB among cattle (Bos taurus), wild elk (Cervus elaphus), and deer (Odocoileus virginianus). Farmer observations of cervids on their farms were evaluated by interviewing 50 farmers that owned a game wire fence for >1 year. Of those interviewed, 82% reported some type of elk or deer damage to hay bales in the field or in their yard prior to fencing. After fencing, 23% of respondents reported some annual damage to stored hay bales that were not inside the fence, but there was a 100% decrease in the estimated annual value of hay losses. Incursions of deer inside the barrier fence were reported by 18% of respondents and most of these were due to leaving gates open. No incursions of elk inside a barrier fence were reported. Despite the important successes achieved, barrier fencing of hay bales alone does not completely protect cattle from bovine tuberculosis.
2001 年，在加拿大马尼托巴省西南部的 Riding Mountain 国家公园周围，启动了一个联邦和省级共同出资的项目，为捆干草储存区提供免费的猎场铁丝围栏，以防止牛（Bos taurus）、野生麋鹿（Cervus elaphus）和鹿（Odocoileus virginianus）之间传播结核病。通过采访拥有猎场铁丝围栏超过 1 年的 50 名农民，评估了农民对其农场中鹿科动物的观察结果。在接受采访的人中，82%的人报告说在围栏之前，田间或院子里的干草捆有某种类型的麋鹿或鹿损坏。围栏后，23%的受访者报告说，储存在围栏外的干草捆每年都会受到一些损坏，但干草损失的估计年价值减少了 100%。18%的受访者报告说有鹿闯入围栏，其中大部分是因为门没关。没有报告说有麋鹿闯入围栏。尽管取得了重要的成功，但仅用猎场铁丝围栏围住干草并不能完全保护牛免受牛结核病的侵害。
