Authors : E.O. Amasaib , H.E. Mohamed and A.N.M.A. Fadel Elseed

Abstract: This study was conducted to compare some productive traits of imported versus locally bred and crossbred dairy cows (50, 56.5 and 62.5%) in 2 different farms in Khartoum, Sudan. The correlations between milk yield and lactation length for the 1st 3 lactations for Butana farm and the university farm were found to be 0.669 and 0.746, respectively. However, the correlation between total and 100 days mil yield for the 1st three lactations were found to be 0.762 and 0.746 for Butana and the university far, respectively. As for the breed effects, the 100 days milk yield were found to be 2156.6599, 1566.67383, 894.7352.01, 732.761711.1 and 888.03331.96 kg for imported Holstein-Friesian, locally born Holstein-Friesian, 50, 56 and 62.5% Friesian blood, respectively.
