Abstract | The experiment was conducted to study the physiological indicator of Tegal duck based on the hematological parameters and its relation to reproduction performances.ÃÂÃÂ The research materials were 20 heads of male and 100 heads of female Tegal ducks. Parameters measured were erytrocyte, leucocyte, differential leucocyte, hemoglobin, hematocrit, protein total, albumin and globulin, and reproduction performances (semen volume and egg production).ÃÂÃÂ Method of the research was experimental with Completely Randomized Design,ÃÂÃÂ and data were analysed using analysis of variance and correlation.ÃÂÃÂ The result of the experiment showed that hematological parameters of Tegal duck that had high production were high significantly (P<0,05) different than the others, except on albumin value.ÃÂÃÂ It was concluded that reprodution performances of Tegal duck was highly affected by its hematologys status.
