Abstract
This study was conducted to evaluate the effects of feeding mash versus pellet with different thermal process on blood metabolites, carcass characteristics and broiler performance. 192 (one-day) Cobb broiler chicks were used in a completely randomized design with 4 experimental groups (diets) and 4 replicates of ten chicks each (totally 16 pens). The experimental treatment groups consisted of mash diet (control) and three experimental diets pelleted with temperatures of 72, 82 and 92 ◦C. Results indicated that effects of different temperatures of thermal process had a significant effect on feed intake in 1-42 days period (P<0.05). The process effect was significant on body weight gain between treatment groups only in starter period (P<0.05). Thermal processes of diets improved feed conversion in starter period (P<0.05). In total period, the process of 82 ◦C improved feed conversion in broiler chickens. Percentages of carcass traits including breast, thigh, gizzard and stomach, liver and gallbladder, intestines, heart and digestive system weren’t different among  experimental groups (P>0.05). Effect of the process on serum glucose, cholesterol, HDL, LDL and enzyme concentrations of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) wasn’t significant at 49 days (P>0.05).
