The broiler industry is the most developed livestock sector in Cameroon. This study aimed to evaluate the relationship between biosecurity implementation with production performance and antibiotic usage in broiler farms in Cameroon. Data concerning biosecurity, production performance (average daily gain or ADG, mortality rate, feed conversion ratio or FCR, and performance index or PI), and antimicrobial usage (AMU) were collected in 57 farms in the Adamawa and North regions. The average total biosecurity score of broiler farms was 52/100. ADG (46.54 ± 5.18 g versus 43.80 ± 4.16 g), FCR (1.59 ± 0.61 versus 1.75 ± 0.58), mortality rate (2.47% versus 6.65%), and PI (339.21 ± 105.79 versus 268.22 ± 101.09) were statistically better in farms with good biosecurity. The majority of antibiotics used (55.2%) were classified as critically important for human medicine, with 83.9% of antibiotics underdosed/overdosed. No correlation was found between biosecurity and AMU, although there was a trend towards reduced use in farms with good biosecurity. The misuse of antibiotics will result in an increased development of antimicrobial resistance, which can be transmitted to humans. This study highlights the importance of biosecurity in improving poultry performance and reducing AMU. Continuous training and awareness-raising efforts among farmers on the importance of biosecurity are needed to reduce AMU and improve farmers' profitability.
肉鸡产业是喀麦隆最发达的畜牧业部门。本研究旨在评估喀麦隆肉鸡养殖场生物安全措施的实施与生产性能及抗生素使用之间的关系。在阿达马瓦和北部地区的57个养殖场收集了有关生物安全、生产性能（平均日增重或ADG、死亡率、饲料转化率或FCR以及性能指数或PI）和抗菌药物使用（AMU）的数据。肉鸡养殖场的平均生物安全总评分为52/100。生物安全措施良好的养殖场在ADG（46.54±5.18克对43.80±4.16克）、FCR（1.59±0.61对1.75±0.58）、死亡率（2.47%对6.65%）和PI（339.21±105.79对268.22±101.09）方面在统计学上表现更好。使用的大多数抗生素（55.2%）被归类为对人类医学至关重要，83.9%的抗生素存在剂量不足/过量的情况。尽管生物安全措施良好的养殖场有抗生素使用减少的趋势，但未发现生物安全与AMU之间存在相关性。抗生素的滥用将导致抗菌药物耐药性的增加，这可能会传播给人类。本研究强调了生物安全在提高家禽生产性能和减少AMU方面的重要性。需要对农民进行持续培训并提高他们对生物安全重要性的认识，以减少AMU并提高农民的盈利能力。
