1
Data represent the mean of 5 cages (10 broiler chickens/cage) per treatment.
2
Control – diet without oilseeds. CAM.IR – diet with 15% of infrared-irradiated camelina seeds. SUN.IR – diet with 15% of infrared-irradiated sunflower seeds. FLA.IR - with 15% of infrared-irradiated flax seeds.
3
SEM - standard error of the mean.
4
P < 0.05; a,bstatistical differences.
5
Throughout the rearing cycle, the preparation and analysis of nutrient utilization lasted 7 d and ended on the last d of rearing: 35 and 42d.
