To this end, 311 Balamis sheep (75.9% females: 24.1% males) distributed over 99 holdings and 10 sites were characterized. Morphometric measurements have been used to evaluate the characteristics of various breeds of animals and could provide first-hand information on the suitability of animals for selection [4]. En effet, les paramètres phénotypiques quantitatifs sont directement corrélés aux paramètres de production (FAO, 2012), leur connaissance est donc importante pour la maîtrise et l’amélioration des performances de production des animaux. AJOL is annually audited and was also independently assessed in 2019 by E&Y.

Spatial variation in goat populations from Benin as revealed by multivariate analysis of morphological traits. Balami and Uda sheep were obtained from markets in these states. Productivity of ewes estimated as weight of weaned lamb per annum or as weight of weaned lamb per kg metabolic weight of ewe per annum increased with the age of ewe to about 55 months of age. Pour cela, et du fait que l’essentiel des variables principales mais aussi supplémentaires ont leurs cosinus carrés élevés sur ces axes, le premier plan factoriel (F1xF2) s’adapte bien pour l’interprétation des résultats de l’analyse.
