Farmers’ perceptions of bovine brucellosis in Benin

TL;DR

This study explores how farmers in Benin perceive bovine brucellosis, revealing low awareness and highlighting the need for better education to improve disease control and public health.

Contribution

The study identifies distinct farmer perception groups and provides insights into knowledge gaps about bovine brucellosis in different agroecological zones of Benin.

Findings

Only 38% of farmers were aware of brucellosis, with higher knowledge in Zones 1 and 4.

Ethnic Dendi herders showed better knowledge compared to other groups.

Most farmers preferred treating sick animals rather than selling them.

Abstract

Cattle are the main source of meat in Benin. To improve the attitudes and practices of cattle breeders in relation to bovine brucellosis, a study has been carried out in Benin according to different agroecological zones. This study aimed to assess farmers’ knowledge and practices concerning bovine brucellosis to generate essential information for control programs and public health interventions.

The study was conducted from February to May 2022, during which 608 farmers were interviewed using a structured questionnaire that provided information on socioeconomic characteristics, knowledge, and practices related to bovine brucellosis. Analysis of variance, Poisson regression, and the proportion comparison test were used to compare these characteristics in the different agroecological zones. At the end of the surveys, three distinct and homogeneous groups of perceptions (hierarchical classification of Multiple Correspondence Analysis components of R software) of bovine brucellosis were identified (these groups only consider farmers who declared knowledge of the disease). Groups were formed by applying the multiple correspondence analysis function of the FactoMineR library in R software, followed by a hierarchical ascending classification using the hierarchical clustering on principal component function of the same software (Agrocampus Rennes, France).

Only 38% of respondents were aware of brucellosis. Knowledge of brucellosis was not related to sex or education level but was higher among farmers in agroecological Zones 1 and 4. Ethnic Dendi herders (62.16%) had better knowledge of the disease than those from other sociolinguistic groups (Somba: 50%, Fulani: 40.91%, Baribas: 26.97%, and others: 8.82%). Reduced milk production (98.29%), presence of hygroma (87.18%), and abortion (56.84%) are the main signs reported by herders familiar with the disease. All three groups had good knowledge of the disease and its zoonotic nature. Groups 1 (96% of breeders) and 2 (2.14%) were aware of the risk factors (contact with affected animals, the consumption of raw milk, the handling of runts, and reproductive rejection). In the case of Brucella, they prefer to treat animals rather than sell them and use both traditional and modern medicines. Group 3 (1.71%) did not know the risk factors and preferred to sell animals in the event of illness.

Pastoralists need to be made aware of the mode of transmission of bovine brucellosis, its clinical manifestations, its impact on animal health, and the zoonotic nature of the disease (impact on public health) so that bovine brucellosis can be rapidly detected in herds.
