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.
