This study was conducted by investigation the effect of different concentration eggplant peel extract (0, 2, 4, 6 and 8 percent/ml) in extender with based Tris-egg yolk on the experiment Farahani ram breeding. Semen samples were collected from five mature Farahani ram breeding twice in the week by an artificial vagina, after equilibration at five degrees centigrade the samples, sealing by 0/5 straw and were frozen with nitrogen vapor and immersed in liquid nitrogen and were stored by using for assessment. Semen’s were thawed at 37℃ and then assessed for analysis of membrane integrity (HOST) by computer analysis (CASA). The result of this experiment showed that the extender containing about 2 percent/ml of eggplant peel extract significantly improved cell membrane integrity compared to control group (p<0/01). After that the extenders containing about 4 percent/ml from eggplant extract peel and control groups had an equal relation of significant (p<0/01). With the attention this conclude of this experiment addition 2 percent/ml of eggplant peel extract to Tris extender could be suitable for preservation of cell membrane integrity.
