Dietary inclusion of dried tomato pomace improves the seminal characteristics in Iranian native roosters. "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 ≤ 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 × time (wk) interaction was also found for most of seminal characteristics, except for the sperm forward motility (P ≤ 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."
