Distribution phenotypic of the dairy production of goat in Tunisia

Abstract

To identify some genetic specificities of goat meat production in southern Tunisia, sixteen years data monitoring of 993observations were analysed. Data distribution was studied to establish the performances regrouping pattern toward oasian breeding conditions depending on the dairy production. The average of production by lactation and daily lactation was 216.19 and 151.52 respectively. The coefficient of variation of those phenotypic varied largely between 0.5 and 0.25 respectively of production by lactation and daily lactation. Thus, goat data variation changes in relation to the phenotype.
