Bibliographic record
Abstract
Les statistiques sur les paramètres démographiques et zootechniques du cheptel bovin est essentielles pour l'élaboration des stratégies de développement appropriées et l'intensification durable de la production laitière en Afrique de l’Ouest. C’est dans cette optique que la présente étude est menée. L’objectif de l’étude est de déterminer les paramètres démographiques et zootechniques du cheptel bovin de la zone péri-urbaine de Bobo-Dioulasso, à l’Ouest du Burkina Faso. La méthode d’enquête rétrospective des douze derniers mois (12mo) a été utilisée. Il a concerné au total 64 troupeaux laitiers installés à la périphérie de la ville dans quatre campements riverains. Les résultats obtenus indiquent que la taille moyenne des troupeaux est de 46 têtes dont 70% de femelles. Les races Zébus peulh soudanien et les métis Méré sont les races dominantes avec respectivement 80% et 15%. Les autres races notamment le Zébu Goudali, le Zébu M’Bororo, Zébu Azawak, le Gir et leurs métis ne représentent que 5% du cheptel enquêté. Le taux de mise bas pour les 12 mois qui ont précédés l’enquête varie entre 46,77% et 56,35% pour l’ensemble des troupeaux. Le taux de mortalité global est en moyenne de 6,85% ; il est relativement plus élevé chez les veaux (24,82%). Le taux d’exploitation global est de 13,20% dont 22,70% pour les mâles et de 9,71% pour les femelles. Les performances des troupeaux enquêtés sont caractéristiques des troupeaux laitiers extensifs en voix d’intensification.

English Title: Analyses of demographic and zootechnic parameters of peri-urban dairy herd of Bobo Dioulasso, Burkina Faso Information on the demographic and zootechnic parameters of cattle herds is key for designing appropriate development and sustainable intensification of dairy sector in West Africa. For this purpose, we conducted this study which aim is to assess the demographic and zootechnic parameters of the peri-urban dairy cattle herds in Bobo Dioulasso in western Burkina Faso. The 12 months’ retrospectives herd survey method (12mo) was used. It covered in total, sixty-four (64) dairy herds in the peri-urban area of the city from four livestock keepers’ camps. Results indicated that average herd size is 46 heads of cattle with 70% of females dairy cows. Zebu peulh Soudanien (also called Fulani Sudanese Zebu) and it crossed breeds with taurin breeds (called Méré) were the dominants breeds kept, representing about 80% et 15% of the total herd, respectively. Other breeds such as Zebu Goudali, Zebu M’Bororo, Zebu Azawak, Gir and their crossed breeds cows represent only 5% of the herds monitored. Birth rate of the 12 months preceding the survey varies from 46.77% to 56.35%. Average global mortality rate was estimated about 6.85% but mortality rate for youth animals was higher (24.82%). Global off take rate is estimated about 13.20% with higher rate for male (22.70%) as compared to females (9.71%). Our findings show that the peri-urban herds monitored are in extensive dairy production systems towards intensification. Keywords: 12mo Survey, demographic and zootechnic parameters, peri-urban livestock, sub humid zone, Burkina Faso.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
