Summary:

Data used in the present study which was performed at Central Cattle Breeding and Dairy Farm (CCBDF), Savar, Dhaka. The productive efficiency on sixteen bulls of three genetic groups (8 Brahman cross, 5 Friesian cross and 3 Local) over a period of 9 months (April to December, 2015) were analyzed to comparison, estimate of heritability, and genetic and phenotypic correlations of semen parameters where semen of Brahman crossbred bulls was used to inseminate indigenous cows to investigate the meat production potentialities of local cattle. Parameters of semen as volume (ml), color, consistency, mass activity, motility (%), sperm concentration (×106/ml) and non-return rate (%) were considered. Genotype ranking was also taken into account for the study.The individual genotypes had significant (p<0.05) effect on semen parameters. The maximum ejaculate volume (7.86±0.19 ml), progressive motility (65.80±1.51%) and sperm concentration (1516.59±33.07 ×106/ml) was established in FG, BG and LG, respectively. According to the phenotypic value of semen parameters, the genetic groups of Local were superior to other genotypes and the lowest value in FG but BG stood an in-between position.
