Abstract
This study was conducted to evaluate the effects of using rapeseed and wheat irradiated with electron on performance, blood parameters, antibody titer and intestinal morphology in broiler chickens. In this study, 300 one-day-old broiler chickens (mixed male and female) of Ross 308 strain were assigned to 4 experimental treatments with five repetitions and 15 chickens in each repetition in a completely random design. The experimental treatments included the control group (without rapeseed meal and wheat) and the treatments containing rapeseed meal and wheat with radiation dose of 10, 20 and 30 kGy. The results showed that in the body weight during the grower period, the control group had the highest body weight compared to other treatments (P<0.05). In the total period, the control group and the treatment group with a radiation dose of 30 kGy had the highest body weight (P<0.05). In the feed consumed during the grower period and the total period, the control and treatment groups with a radiation dose of 30 kGy had the highest amount (P<0.05). In the feed conversion ratio, the control group had the lowest value compared to other treatments in the final period and the total period (P<0.05). The treatment with radiation dose of 30 kGy had the highest villus length and layer thickness compared to other treatments (P<0.05).The general results of the present study showed that irradiation of rapeseed and wheat flour with a dose of 30 kGy improved the characteristics of growth performance and morphology of the jejunum.
