Because of a paucity of information on the effect of tomato pomace in male chickens, a study was undertaken to determine the influence of dietary inclusion of dried tomato pomace (DTP) on seminal characteristics in Iranian native breeder roosters. Fifty-four roosters (24 wk old) were randomly allotted to 3 treatment groups and received either a basal diet without DTP (T-0), or a diet containing 15% (T-15) or 30% (T-30) DTP for an 8-wk-long experimental period. Semen samples were obtained weekly by abdominal massage to evaluate the seminal characteristics. Dietary inclusion of DTP increased sperm concentration, accompanied by a decreased seminal volume (P %26lt;= 0.05). The percentage of live sperm in ejaculate was increased in T-15 and T-30 groups, but sperm forward motility was not affected by DTP inclusion. A decreased percentage of abnormal sperm and improved membrane integrity (as determined by the hypoosmotic swelling test) were observed in T-15 and T-30 groups. Lower concentration of thiobarbituric acid reactive substances (as an index of sperm membrane lipid peroxidation) was recorded in roosters fed DTP. A diet x time (wk) interaction was also found for most of seminal characteristics, except for the sperm forward motility (P %26lt;= 0.05). The results indicated that dietary inclusion of DTP up to 30% improved seminal quality attributes within 4 to 5 wk in roosters; however, the underlying mechanism(s) warrants further study.
