    Abstract:
    The recent outbreak of avian influenza in the poultry sector of Cameroon has raised a concern about the level of implementation of biosecurity measures (BM) on poultry farms. Therefore, a study using a questionnaire on 102 randomly selected poultry farms was undertaken. Some measures with high adoption levels (> 90%) included "protection of airing openings of poultry barns by a wire mesh," "no external animal allowed to enter the farm," "respect of all-in all-out principle," "functional footbath," "rodent control," and "feedstuff protection from access to rodents." The least implemented measures (less than 20%) were "wearing of dedicated clothing (clean coveralls and boots) by workers," "disinfection of visitors," and "presence of storage room for dead animals." Only for "isolation" component of biosecurity, compliance with biosecurity measures was good, with more than 50% of farms having an adoption rate greater than 75%. The mean biosecurity score for the assessed farms was 19.29 ± 1.89 for a maximum score of 38 points. The score was significantly and positively correlated (p < 0.05) with the number of chicken and the geographic location of farms. The other results showed that the mean number of broiler per cycle was 550.82 ± 76 for a stocking density of 27.20 ± 6.64 birds per m2. In conclusion, broiler production in the Western highland is dominated by small-scale units with low level of biosecurity practices positively and significantly (p < 0.05) influenced by some production characteristics. To improve biosecurity practices in the area, efforts must focus on measures concerning "sanitation" and "traffic control" components of biosecurity.
