In this experiment, the effect of garlic (GP) and tomato (TP) powders on performance, blood parameters, sex differentiation and hatchability of Ross-308 broiler breeders were examined and compared with In-Ovo injection of garlic or tomato hydroalcoholic extracts. In first experiment, 375 hens and 25 roosters (47 wk.) were randomly allocated to 5 treatments and 5 replicates, for 4 weeks. Treatments included: 1) basal diet (control), 2 and 3) basal diet+ 2 and 4 percent of GP, and 4 and 5) basal diet + 2 and 4 percent of TP, respectively. In second experiment, 200 hens and 20 roosters were randomly allocated to 2 treatments including 1) basal diet and 2) basal diet + 4% of TP (selected treatment of the Exp. 1) in 5 replications from 52-56 wk. During incubation period, experimental treatments included: 1) control group, 2) eggs from hens fed 4% TP, 3) In-Ovo injection of physiological serum and 4 and 5) In-Ovo injection of 0.1 and 0.3 ml of garlic and tomato hydroalcoholic extracts. The results of first experiment, adding garlic and tomato powders was not significant on egg qualitative traits and blood parameters (P>0.05). All In-Ovo injection treatments increased fertility percentage (P<0.05). The second experiment results showed that treatments had no significant effect on the percent of males and females (P>0.05). In general, addition of 4 percent tomato powder to broiler breeders in comparison to In-Ovo injection of hydroalcoholic extracts of garlic and tomato, did not increase male 1-d-old chicks’ percentage of hatched chicks.
