L'étude analyse les déterminants socioéconomiques et institutionnels favorisant les échecs de traitement aux trypanocides contre la trypanosomose animale africaine dans l'Ouest du Burkina Faso. Elle met en évidence que le sous-dosage, l'usage de produits de mauvaise qualité et la faiblesse de l'encadrement vétérinaire accentuent la résistance parasitaire, nécessitant une approche de lutte intégrée.

This study aims to analyze the determinants of the acceptability of solar meat drying in the municipalities of Kaya and Kongoussi in the livestock potential. The methodology combined qualitative and quantitative approaches, through five focus groups and the administration of individual survey forms to 138 actors in the meat sector (processors, butchers, restaurateurs, and grillers). A logit model was used to identify the determinants of the acceptability of meat dried in solar dryers. The results indicate that the tested technology was well received by respondents. They also reveal that prior knowledge of the technology have a positive influence on its acceptability. However, the high cost of the dryer remains the main barrier to its acceptability. It is essential to strengthen awareness raising activities on the usefulness of the technology. The price of the solar dryer should also be s...

Background: Pastoral and agropastoral households in Burkina Faso face ecological and social pressures that may influence their adaptation strategies. Aims: To identify the factors associated with the selection of pastoral adaptation strategies to understand the diversity of observed practices and guide policies that support herders. Study Design: Cross-sectional household survey with a semi-structured questionnaire; stratified purposive sampling of households. Place and Duration of Study: 38 villages in nine communes of the Sahelian and Sudanian zones of Burkina Faso, October 2023. Methodology: Data were obtained through interviews with the heads of 125 pastoral and agropastoral households using a semi-structured questionnaire. Households could report several strategies. Associations with household status, herd composition and commune were tested with chi-square tests (Monte Carlo P v...

L’étude visait à évaluer les caractéristiques chimiques des substrats organiques locaux utilisés pour amender les parcelles agricoles dans la zone cotonnière à l’ouest du Burkina Faso afin de favoriser une meilleure valorisation de ces substrats locaux. Pour la conduite, sept types de fumures organiques notamment le compost villageois, fumier d’étable, fumier de petits ruminants, terre de parc, ordures ménagères et deux fumiers expérimentaux ont été collectés sur six sites dans les provinces de Tuy et Mouhoun au Burkina Faso. Les mesures ont été effectuées sur le pHeau, la teneur en matière organique, et les teneurs en éléments nutritifs majeurs (N,P,K). Les fumures organiques se sont révélées faiblement acide à légèrement basique (6,96±0,82 à 8,82±0,15) et une teneur acceptable en matière organique (13,56±5,03% à 38,05±10,46%) par rapport aux normes recommandées (10% à plus de 30%). Le...

Introduction : L’amputation correspond à la perte de tout ou partie d’un ou de plusieurs membres. Elle entraine une modification biomécanique majeure de l’appareil locomoteur. En Afrique les possibilités d’appareillage sont souvent limitées. L’objectif de cette étude était de décrire les aspects épidémiologiques, cliniques, thérapeutiques et le devenir des amputés de membres d’origine non traumatique. Patients et méthode : Il s’est agi d’une étude rétrospective sur une période 36 mois. Les données socioprofessionnelles, cliniques, para cliniques et thérapeutiques des patients admis dans le service de chirurgie pour une amputation d’origine non traumatique de membre ont été analysées. Résultats : Quarante-sept patients (31 hommes et 16 femmes) ont été colligés. Ils étaient en majorité des cultivateurs (N=28) et des ménagères (N=16). L’âge moyen était de 57 ans. Le délai...

The processes involved in feeding a warehouse require such a high level of expertise that they are generally entrusted to an IT specialist (data administrator). This requires, first, that decision-makers express their needs to the IT specialist and, second, that the data warehouse developed by this IT specialist be validated. In the era of open decision-making information (self-service BI), decision-makers increasingly want to integrate and analyze data themselves without the help of experts. Added to this is the diversity of data, its speed of evolution, and its ever-increasing volume, which hinder traditional ETL approaches because they can no longer meet new requirements. We therefore offer an assistance process that allows decision-makers to integrate data themselves (Extract-Transform-Load: ETL) into a data warehouse using Large Language Models (LLMs) and ontology, without the need...

Background: Fermented Zamné is a traditional condiment produced from Senegalia macrostachya seeds. Aims: This study aims to isolate and characterise predominant Bacillus-related bacteria from fermented Zamné and to evaluate their antimicrobial activity against selected indicator microorganisms. Methods: A total of 65 aerobic mesophilic bacterial isolates obtained from four independent fermentations were characterised using morphological and biochemical methods. Forty-four isolates were spore-forming, and 29 isolates displaying morphological characteristics consistent with Bacillus-related bacteria were further characterised and identified using the API 50 CHB system. The antimicrobial activity of the isolates was evaluated by an agar well diffusion assay against 13 indicator microorganisms, including Gram-positive and Gram-negative bacteria, yeasts, and moulds. Results: The isola...

Approximately 65% of agricultural land in the Sudano-Sahelian zone of Burkina Faso consists of degraded bare soils requiring urgent restoration. Although zaï technology is widely adopted, the influence of pit dimensions and their interaction with organic and mineral fertilisation on soil restoration remain insufficiently understood. A split-plot design was installed in 2019 on two contrasting bare soils: Toyendé (moderately acidic lixisol, Sudano-Sahelian) and Gouéré (near-neutral plinthosol, Sahelian). The main factor comprised four rectangular zaï pit lengths (30, 35, 40, 45 cm) and one circular pit (30 cm), all 20 cm deep in order to compare the performance of the two types of zaï in terms of water collection and the trapping of plant residues in the pits. The sub-factor comprised four fertilisation regimes: no input, compost (250–500 g/pit), NPK (6.5 g/pit) and compost + NPK. After t...

We develop a nonlinear host–vector model to describe the transmission dynamics of Tomato Yellow Leaf Curl Virus (TYLCV) in tomato crops. The model couples an SEIR structure for the plant population with an SI formulation for the vector Bemisia tabaci, incorporating logistic growth and saturated incidence functions

In African catfish hatchery systems, post-stripping egg storage duration may vary among operators, and different additives are sometimes used empirically for sperm activation during artificial fertilisation. This study assessed the effects of post-stripping egg storage duration and sperm activation media on sperm motility characteristics and fertilisation success in C. gariepinus. Three egg storage durations (11, 38, and 71 min) and four sperm activation media (borehole water, sugar–salt borehole water, sugar borehole water, and saline borehole water) were evaluated with three replicates. Regarding sperm motility characteristics, borehole water resulted in the highest motility rate (83.3 ± 5.8%), whereas salt-containing activation media produced the lowest values (10.0 ± 8.7% and 4.0 ± 1.7%). However, no significant relationship was observed between sperm motility parameters (motility ra...
