The effect of dried corn steep liquor (DCSL) and probiotics on growth performance, intestinal microbial population and humoral immune response of broilers using 320 one-day-old Ross 308 broilers in a 2 × 4 factorial arrangement experiment with four DCSL levels (zero, two, four and six percent) and two levels of probiotic LactoFeed® (zero and 150 mg/kg) were evaluated in a completely randomized design with eight treatments, four replicates and 10 birds per replication for 42 days. Body weight gain, feed intake, feed conversion ratio, lactic acid and coliform bacterial populations, as well as the response of broiler chickens' humoral immune system against Newcastle disease, bronchitis and influenza viruses were measured. In the grower, finisher and whole period effect of LactoFeed probiotics and DCSL and their interaction on body weight gain and feed conversion ratio were not significantly different. In the starter period, birds fed diets containing four percent DCSL consumed more feed and gained more weight than chickens fed diet without DCSL (P<0.05). Interaction of six percent DCSL and probiotic increased feed intake in the starter period compared to diet lacking these compounds (P<0.05). The greatest antibody titer against Newcastle disease, influenza and bronchitis viruses was observed at six percent of DCSL (P<0.05). The interaction of DCSL and probiotics decreased the population of coliforms and increased the population of lactic acid bacteria (P<0.05). According to the results of this study, the use of DCSL and probiotics in the diet of broilers improves the humoral immune response and intestinal microbial population.

Abstract
In this research the effect of Bioplus B2 probiotic and galactooligosaccharide prebiotic (GOS) on performance, egg quality, and some blood parameters of commercial laying hens were investigated in a sample of 216 hy-line laying hens (w36) with the same average weight aging 50 to 62 weeks for a period ...

In this research the effect of Bioplus B2 probiotic and galactooligosaccharide prebiotic (GOS) on performance, egg quality, and some blood parameters of commercial laying hens were investigated in a sample of 216 hy-line laying hens (w36) with the same average weight aging 50 to 62 weeks for a period of 12 weeks in a completely randomized design with 6 treatments, 6 replications and 6 hens per each replication in the cage system. Experimental treatments included 1) without additives (as control), 2) diets containing 0.1% Bioplus B2 probiotic, 3) to 6) diets; containing, 0.05, 0.1, 0.15 and 0.20 % of galactooligosaccharides prebiotic, respectively. The results indicated that both egg weight and mass was increased significantly (P<0.05) in the Bioplus B2 probiotic treatment. Egg production percentage, feed intake and feed conversion ratio were not significantly influenced by treatments. Using galactooligosaccharide at the levels of 0.05, 0.1 and 0.2 percent improved dry eggshell weight significantly while the levels of 0.05, 0.15 and 0.2 percent increased eggshell weight per unit area compared to the control (P<0.05). Total protein and albumin of serum increased in the Bioplus B2 treatment (P<0.05). Using Bioplus B2 probiotic and 0.15% galactooligosaccharide significantly decreased blood cholesterol level (P<0.05). In general, the results showed that the using of prebiotic galactooligosaccharide at the level of 0.15 % increases the weight of eggshell per unit area, decreases the blood serum cholesterol, and improves some performance traits compared to control group, therefore it can be used instead of probiotic Bioplus B2.

Effect of different levels of ginger (Zingiber officinale) and Protexin® probiotics on performance, humoral immune response and Ileal microbial population were evaluated using 360 birds in a completely randomized design as 2 × 3 factorial arrangement with 3 levels of ginger powder (0, 2.5 and 5 g per kg), and 2 levels of probiotics (0 and 150 mg per kg) in 6 treatments and 5 replicates of 12 birds for 28 days. Birds consumed greater amount of diet containing 2.5 g/kg ginger (P<0.05). Birds fed diet containing 150 mg/kg of probiotics had higher feed intake and weight gain, and lower feed conversion ratio (P<0.05). Feed intake was higher in birds fed diet containing 2.5 g/kg ginger and 150 mg/kg probiotics compared with those birds received diet without ginger and probiotics (P<0.05). Consumption of probiotics, ginger and combination of probiotics and ginger increased antibody titer against secondary challenge with sheep red blood cells compared with those birds received diet without ginger and probiotics (P<0.05). Antibody titers against Newcastle virus were not affected by supplementation of ginger and probiotics. Supplementation of diet with probiotics alone and in combination with ginger increased Ileal lactic acid bacteria and total bacterial population compared with diet without ginger and probiotics (P<0.05). Based on the result of current study, supplementation of Japanese quail’s diet with 2.5 g/kg ginger and 150 mg/kg probiotics could improve feed intake, immune response and ileal microbial ecosystem.

Effect of Protexin to diminish negative consequences of feeding aflatoxin B1 (AFB1) contaminated diet on performance, immune response, meat quality and ileal microbial flora were examined using 320 seven-day-old Japanese quails fed four treatments [control diet (without additives), diet containing 2.5 mg AFB1/kg, diet containing 150 mg Protexin/kg, diet containing 2.5 mg AFB1/kg+150 mg Protexin/kg] with four replicates and 20 birds each in a completely randomized design. Feed intake of birds fed probiotic diet was higher than those birds in control group (P<0.05). Weight gain in birds fed aflatoxin contaminated diet was lower than birds in other treatments (P<0.05). Humoral immunity response in quails related to aflatoxin and probiotic groups was lower and higher than control group, respectively (P<0.05). Skin thickness increase after 48h challenging with dinitrochlorobenzene (DNCB) in birds fed aflatoxin contaminated diet was lower than the other groups (P<0.05). Concentration of malondialdehyde (after freezing meat for 30 days) in the meat of aflatoxin fed birds was higher than the other birds (P<0.05). Population of E. coli and lactic acid bacteria in birds fed protexin or aflatoxin+protexin was lower and higher than the two other groups, respectively (P<0.05). Based on the result of this research, dietary inclusion of protexin probiotics into aflatoxin contaminated diet could improve immunity response and intestinal microbial population in Japanese quails.
