Abstract

In this research,the heritabilities of some testes characteristics in Ile de France IF x Akkaraman AK Bİ male lambs were estimated. While the heritabilities of left and right testes diameters, left and right testes lengths, left and right testes volumes and scrotal circumference determining before slaughtering were estimated as 0,21, 0,24, 0,04, 0,00, 0,31, 0,15 and 0,00,respectively, the heritabilities of left and right testes volumes, both testes weights, left and right testes circumference determining after slaughtering were estimated as 0,05, 0,00, 0,00, 0,33, 0,27 and 0,00, respectively.
