Also females: egg production (H.D %), mass, eggshell strength, eggs for hatching, fertility, hatching fertile total eggs, weight hatched chicks, blood estrogen, FSH concentrations, also improved FCR H/L ratio. While, seemed lower dead sperm. Females in: cracked embryos. Whereas there non-significant differences among all treatment males: mortality, left-right testicular ratio, shape hormone, females Intake. From had positively performance, males females' parameters, more effective than
