Objectif: Cette etude a eu pour but d’evaluer les performances de croissance des agneaux de race Djallonke dans le departement du pool district d’Ignie en milieu paysan. Methodologie et resultats: Elle a porte sur 74 agneaux issus de 68 brebis et 7 males dans la periode d’Aout 2017 a Mars 2018. Les donnees zootechniques (poids vif, gain moyen quotidien) ont ete recueillies hebdomadairement de la naissance a 180 jours d’âge. Les resultats obtenus ont montre une difference significative de poids a la naissance. Les agneaux issus des naissances simples etaient plus lourds (1,95±0,13kg) que les agneaux des naissances doubles et triples (1,05±0,14kg et 1±00). A partir de 120 jours, les poids des agneaux issus des triples naissances avaient augmente significativement (12,5±0,82kg). Le facteur sexe a influence de maniere significative la croissance ponderale des agneaux de la naissance a J180. Le GMQ (Gain Moyen Quotidien) a ete influence par le type de naissance. Les agneaux nes uniques ont montre des GMQ superieurs suivi des naissances doubles et triples. L’experience des meres a montre des GMQ plus important chez les agneaux issus des meres dont l’âge est compris entre 3 et 4ans alors que les plus faibles ont ete enregistres chez les agneaux issus des meres experimentees (5ans). Le facteur sexe n’a pas influence le gain moyen quotidien a 30 jours (p>0,05). Il a ete cependant determinant par la suite (30-180j) auquel le GMQ des mâles a fortement domine sur celui des femelles. Conclusion et application des resultats: Les resultats obtenus dans cette etude montrent une bonne disposition de la race Djallonke en milieu tropical. Il sied neanmoins de noter que, les performances (croissance ponderale et le gain moyen quotidien) ont ete plus meilleures chez les portees uniques. La  croissance ponderale et le gain moyen quotidien eleves chez les naissances triples met en eclair le probleme de la competition au niveau de leur alimentation avant sevrage au sein d’une meme portee.

Methodology and results: It related to 74 lambs resulting from 68 ewes and 7 rams during the time from August 2017 to March 2018. The zootechnical data (live weight, daily average profit) were collected weekly of the birth at 180 days of age. The results showed a significant difference in weight to the birth. The lambs resulting from the simple births were heavier (1,95±0,13kg) that lambs of the births double and triple (1,05±0,14kg and 1±00). From 120 days, the weights of the lambs resulting from the triple births had increased significantly (12,5±0,82kg). The factor sex significantly influenced the ponderal growth of the lambs of the birth with J180. The GMQ was influenced by the type of birth. The lambs born single showed followed higher GMQ by the double and triple births. The experiment of the mothers showed more important GMQ in the lambs resulting from the mothers whose age lies between 3 and 4ans whereas weakest were recorded in the lambs resulting from the experienced mothers (5ans). The factor sex did not influence the daily average profit at 30 days (p>0,05). It was however determining thereafter (30-180j) to which the GMQ of the males strongly dominated over that of the females. Conclusion and application of results: The results got in this study show a good provision of the Djallonke race in tropical medium. It sied nevertheless to note that, the performances (ponderal growth and daily average profit) were better at the single ranges. The ponderal growth and the average profit daily high at the triple births put in flash the problem of the competition at the level of their food before weaning within the same range Keywords: performance-sheep villager-department Djallonke-medium of the pool
