نویسندگان
چکیده
This study was carried out to determine the phenotypic corelations between different udder sizes and marketable milk yield in Awassi sheep. The animal material of consisted primiparous vs multiparous Marketable were determined after weaning correlations examined features calculated with SPSS package program. At end study, positive significant (P<0.05 P<0.01) teat length, circumference width over teat, yield. It has been evaluated that these can be used selection breeding stocks.
