Abstract
This experiment was conducted in two trials to examine the effect of Probiotics and honey in Ovo and early feeding on performance, immune system and intestinal micro biota of broiler chicks. The first trial carried out in a completely randomized design as 2×2 factorial arrangement with two levels of Probiotics (0 and 0.1% in distilled water) and two levels of honey (0 and 16% in distilled water). On d 18 of incubation, 0.5 ml of experimental solutions was injected into the eggs. After hatching, chicks were without access to feed and water for 48 h. Experimental groups in the second trial were as: 1-control (without access to feed and water in 48 h after hatch) 2- feeding with water containing 10 gr Probiotics per L in 48 h after hatch 3- feeding with water containing 5 percent honey in 48 h after hatch 4- feeding with water containing 10 gr Probiotics per L and 5 percent honey in 48 h after hatch. Both two trials had four treatments, three replicates and 12 fertile eggs in each replicate and hatched chick were raised for 49 days. Results of first trail showed that injection of experimental solutions had no or negative effects on feed intake (P<0.05). Injection of solution containing 0.1 percent Probiotics and 0 percent honey improved weight gain and FCR in whole experiment (1-49 d). Injection of Probiotics increased antibody titer against first and second challenging with sheep red blood cell. Main effects of neither Probiotics nor honey were not significant against NDV (P>0.05). In second trial, feeding with experimental solutions had no effect on feed intake (P>0.05) but birds received Probiotics, honey and Probiotics +honey had higher weight gain, antibody titer against sheep red blood cell and Ileal lactic acid bacterial population (P<0.05).
