Extended transportation times for broiler chicks can cause chicks to become weak and dehydrated prior to placement. This study was conducted to evaluate the effects of delayed access to feed and water and use of semi-solid products (Omajand Irasis) on some biochemical parameters in broilers’ blood, from the hatching to marketing age (42 days). 640 day-old Ross 308 broiler chicks were obtained from a commercial hatchery nearby the rearing facility, and immediately transported to the facility, then allocated to treatment groups. The treatments included: 1) feeding a corn-SBM diet immediately after hatching (as a control), 2) fasting for 16, 32 and 48 h (with no access to water) after hatching, 3) feeding Omaj for 16 and 32 h (no water) after hatching, and 4) feeding Irasis for 16 and 32 h (no water) after hatching. All treatments were followed by feeding a corn-SBM starter (up to 21d), (22-35 d) and finisher (36-42 d) diets. Blood samples were taken at 16th and 32nd hours and 4th and 21st days after hatching. Sera were collected and frozen for later analysis. Samples were analyzed by auto analyzer for levels of glucose, cholesterol, triglycerides using appropriate commercial kits, and triiodothyronine (T3) level was assayed using [125I] RIA kit. For the second group of the treatments, serum glucose level was high in accordance to length of deprivation time. Levels of cholesterol and triglycerides were not affected significantly but serum T3 concentration, which may mediate some of the intestinal effects of feed deprivation, was decreased in fasted broilers. For the third and forth groups (Omaj and Irasis respectively) results were as follows: serum glucose levels for both groups decreased as long as experimental diet continued and after that returned to normal level. Cholesterol response was correlated to that of glucose, while TG levels did not change significantly. Finally, the levels of T3 at the beginning of treatments increased but at the end of the period decreased for both groups. This confirms the role of T3 to make glucose more available for cells.
