Abstract

The study was conducted on 18 Awassi rams, Aged 1.5 - 2 years, divided in to two group; The first group (n = 9) red face and the second group (n = 9) black face, Presented in the farm of IPA Goat Station, Agurguf, Baghdad, Iraq. During the period from 1, March 2002, till the 1,May 2002. Semen were collected twice weekly by Artificial Vagina.
The study were undertaken to show the effect of line inbreed on characters of semen in Awassi ram. The following results had been obtained. Higher volume of ejaculate were observed at second group (0.92 ± 0.26) and lower at first group (0.76 ± 0.26) ml respectively. The breed had a significant effect (P<0.05) on sperm Mass activity and Individual motility. Higher motility were observed at first group (72.78 ± 13.26 and 71.12 ± 12.42)% respectively and lower at second group (70.0 ± 12.89 and 68.75 ± 12.07)% respectively. The inbreed had a significant effect (P<0.05) on sperm count per milliliter and per ejaculate. Higher sperm count per milliliter and per ejaculate were observed at first group (2.51 ± 1.43 and 2.39 ± 1.96) x 109 and lower at second group (1.73 ± 1.40 and 1.75 ± 1.91) x 109.
The inbreed showed no significant difference of group on (percentages of dead; pH of semen and abnormal spermatozoa). It was concluded from this study that inbreed affected on some of characteristics of semen and had no effects on other of character of semen.
