The research was conducted to study the effect of feeding broiler chickens on diets containing isomaltooligosaccharides on the growth performance, carcass traits and immune response. 90-one day old broiler chicks were used according to completely randomized two treatment groups and one control, 30 birds each. Birds fed ad-libitum on basal starter and grower-finisher diets for 35 day. Diets of treatment`s groups contained 0.5 g/Kg and 1 g/Kg of Isomaltooligosaccharides, while the control group fed on the basal diets without Isomaltooligosaccharides supplementation. Dietary supplementation of broiler chickens with Isomaltooligosaccharides improved body weight, feed conversion, carcass traits, two lymphoid organs weight and log antibody titer against avian flu vaccine. Most of the highest values were for birds fed low levels of Isomaltooligosaccharides. Feed intake decreases as Isomaltooligosaccharides level increases. Dietary supplementation with Isomaltooligosaccharides did not affect the lipids profile (triglycerides, total cholesterol, LDL and HDL), however the blood VLDL levels decreased with increased levels of Malondialdehyde and Glutathione reductase. Collectively, Dietary supplementation of broiler chickens with 0.5 g/Kg diet of Isomaltooligosaccharides improved growth performance, carcass traits and immune status.

Oregano Essential Oil

Abstract Essential oils are plant-derived aromatic volatile oils, and they contain bioactive compounds that have been shown to improve poultry nutrition. In this study, we investigated the effects of oregano essential oil (OEO) on intestinal antioxidative capacity, immunity, and gut microbiota of young yellow-feathered chickens. A total of nine hundred and sixty 1-d-old female Qingyuan partridge chickens were randomly allocated to four treatment groups with six replicates of 40 birds each, and the feeding trial was lasted for 30 d. The controls were fed on a basal diet without in-feed antibiotics; the birds in the antibiotic group were fed the basal diet supplemented with 20 mg/kg virginiamycin; the remaining birds were fed the basal diet containing 150 or 300 mg/kg OEO, respectively. Dietary supplementation with 150 or 300 mg/kg OEO increased average daily feed intake (P = 0.057) and average daily gain (P < 0.05). The activities of glutathione peroxidase and total antioxidative capacity in plasma, jejuna, and ileal mucosa were increased by OEO supplementation (P < 0.05), with a trend of lower jejunal content of malonaldehyde (P = 0.062). Moreover, dietary OEO increased the content of secretory immunoglobulin A (P = 0.078) and the relative expression of Claudin 1, Mucin 2, and Avain beta-defensin 1 in ileum (P < 0.05). Sequencing data of 16S rRNA indicated that dietary OEO increased the relative abundance of Firmicutes phylum, and Clostridium and Lactobacillus genera, and decreasing that of Romboutsia. Functional analyses indicated that microbial amino sugar and nucleotide sugar metabolism, replication, and repair systems were higher in OEO groups than those of controls and antibiotic treatment. In conclusion, dietary supplementation with OEO enhanced growth performance, alleviated local oxidative stress in intestine, improved production of natural antibodies, and favorably modulated intestinal microbiota composition.

AbstractThe objective of this experimental study was to investigate the effects of essential oils of oregano, laurel and their combination on growth performance, intestinal microbiota and intestinal morphology as replacers of antibiotic growth promoters, as well as on the antioxidant capacity and mineral content of breast and thigh meat. A total of 256 day-old broiler chickens were randomized into 4 groups with 4 replicates. Control group received a basal corn-soybean diet, whereas the other experimental groups received the basal diet plus 25 mg/kg oregano essential oil, 2.5 mg/kg laurel essential oil or their combination, respectively. Chickens had free access to water and feed. Body weight gain and feed to gain ratio was calculated for the total fattening period and mortality was daily recorded. Intestinal microbiota was enumerated by conventional techniques with selective agar media at the end of the trial at both ileum and caecum. Also, evaluation of intestinal morphology was carried out in small intestine and caecum. At the end of the trial, birds were slaughtered, their carcasses were processed and samples of breast and thigh meat were analyzed for moisture, fat and protein content. Total phenolic content was determined in feeds and breast and thigh meat in order to assess its antioxidant capacity. Mineral content of breast and thigh meat was evaluated by ICP-MS. The results of the trial showed that the group that received oregano or the mixture of oregano and laurel presented better BW and FCR and mortality compared to control group. Bacterial counts for the Lactobacilli and Bifidobacteria were higher in the experimental groups compared to the control group at both ileum and caecum, and total coliforms were lower in caecum in the experimental groups compared to control. Higher values for villus height were found for the oregano supplemented groups compared to control or laurel ones. Oregano supplemented groups showed higher antioxidant capacity of breast and thigh meat compared to control and laurel groups, however no changes in mineral content were noted among the different groups. In conclusion, oregano essential oil alone or as a mixture with laurel essential oil can be used to improve growth performance and gut health in broiler chickens.
