The Effect of Four Barley Cultivars in Whole and Ground Forms on Performance, Nutrients Digestibility and Blood Lipid Parameters of Broiler Chickens

This experiment was conducted to evaluate the effect of barley cultivars and their feeding form on performance, jejunal digesta viscosity, nutrients digestibility and blood parameters of broiler chickens. A total of 512 day-old chicks (Ross 308), as mixed sex, were assigned to experimental treatments using a completely randomized design with factorial arrangement (4×2) for a period of 42 days. Barley cultivars were Dasht, Sahra, CB-74-2 and Makoei and feeding forms were in whole and ground as well. According to the results, barley cultivar had no significant effect on broilers performance and feeding whole grain increased feed intake and feed conversion ratio of the birds (P
