Caractérisation phénotypique de la population ovine dans la région d’Oued Righ

Abstract

La caractérisation phénotypique de la population ovine de la région d’Oued righ. L'objectif de cette étude est la caractérisation phénotypiques de la population ovine de la région d’Oued rihg, des mesures corporelles ont été appliquées sur 60 tête (50 femelles et 10 males). Cette étude qui porte sur 18 variable, les donnés recueilles étés soumises à un barycentre des classes et de coefficient de corrélation. Les résultats obtenus ont montrées des corrélations très hautement significatives concernant (HG, HMA = 0,778), (TS, CT= 0,703), (CT, CA = 0,890), chez les femelles ; et (HG, HMA = 0,938), (HG, L = 0,829), (HG, TAB =0,821), (HMA, L)= 0,862), (HMA, CT = 0,781), (HMA, TAB =0,771), (L, CT= 0,741), (L, CA = 0,830), (L, Tcu= 0,861), (CT, CA = 0,894), chez les mâles. La population ovine de la région d'Oued righ se compose de trois classe pour chaque sexe, ce sont généralement de individus de petit format avec un poids vif (PV) moyenne est égale a 40,9kg chez les mâles et 36,08 kg chez les femelles.Phonotypical characterization of the sheep population the region of Oued Rihg The objective of this study the phenotypic characterization of the sheep population the region of Oued Rihg,body measurements were applied to 60 heads (50 females and 10 males). This study focuses on 18 variables, the data were subjected to a centered of classes and correlation. The results obtained have shown high correlation on (HG, HMA = 0,778), (TS, CT= 0,703), (CT, CA = 0,890), in females ; et (HG, HMA = 0,938), (HG, L = 0,829), (HG, TAB =0,821), (HMA, L)= 0,862), (HMA, CT = 0,781), (HMA, TAB =0,771), (L, CT= 0,741), (L, CA = 0,830), (L, Tcu= 0,861), (CT, CA = 0,894), in males. Sheep population in the region of Oued Rihg consists of three classes for each sex, they are usually a few small individuals with an average size PV is equal to 40,9 kg in males and 36,08kg in females.
