Dietary essential oils improve the hepatic antioxidative status of broiler chickens

The objective of the present research was to assess the dietary supplementation of three formulations of essential oils (EO) in chickens under heat stress (HS). Day-of-hatch Cobb 500 chicks (n = 500) were randomly distributed into four groups: 1. HS control + control diets; 2. HS + control diets supplemented with 37 ppm EO of Lippia origanoides (LO); 3. HS + control diets supplemented with 45 ppm LO + 45 ppm EO of Rosmarinus officinalis (RO) + 300 ppm red beetroot; 4. HS + 45 ppm LO + 45 ppm RO + 300 ppm natural betaine. Chickens that received the EO showed significant (p < 0.05) improvement on BW, BWG, FI, and FCR compared to control HS chickens. Average body core temperature in group 3 and group 4 was significantly (p < 0.05) reduced compared with the HS control group and group 2. Experimental groups showed a significant reduction in FITC-d at 42 days, a significant increase in SOD at both days but a significant reduction of IFN-γ and IgA compared with HS control (p < 0.05). Bone mineralization was significantly improved by EO treatments (p < 0.05). Together these data suggest that supplemental dietary EO may reduce the harmful effects of HS.

Entire Experiment

The objective of this study was to determine the influence of phytogenic product-supplemented, organic acid-supplemented, and prebiotic-supplemented diets on the production results, antioxidative status, and selected welfare indices in broiler chickens. A total of 1155 one-day old male Ross 308 broilers were randomly assigned to one of three treatment groups: Group C, no additives; Group A, supplemented with phytogenic supplement (50% hop); and Group P, supplemented with 65% organic acids and their salts, and 30% prebiotic complex. Health condition and production results were monitored during the entire experiment. After 42 days, 10 birds from each dietary treatment group were selected for blood sampling and slaughter analysis. The results obtained revealed that over the whole feeding period, none of the investigated additives significantly affected broiler performance indices. However, feeding the birds treatment-A increased the relative abundance of Bifidobacterium in caecal digesta compared to the other treatments, whereas feeding treatment-P increased the relative abundance of Lactobacillus compared to the control treatment. Overall, treatment-A was more effective at increasing relative abundance of Clostridia in birds at 42 days of age than treatment-P. Finally, there were no changes in blood levels of antioxidant indices or liver function indicators.

Plant Substances

Vegetable feed additive “Biostrong 510” based on essential oils and plant substances contains active substances exclusively of vegetable origin, which have a more intense eff ect on the animal’s body. The mechanism of action is based on the synergism of several plant substances containing active substances that, when combined, aff ect a certain category of animals. The additive contains essential oils, herbal plants, and seasonings such as anise oil, thyme oil, gentian powder, chili paprika powder, and quillaya extract. The purpose of the research was to determine the feasibility and eff ectiveness of fortifi cation of compound feed with the vegetable feed additive based on essential oils and vegetable substances to increase meat productivity and meat quality. In order to study the eff ectiveness of feeding vegetable feed additive in compound feed for broiler chickens under the conditions of LLC “Akashevskaya poultry Farm” in the Republic of Mari El, a scientifi c and economic experiment has been carried out. Experiments have been performed on broiler chickens of the cross Cobb-500 from the daily to 40-day age of the birds. The eff ect of the vegetable feed additive “Biostrong 510” based on essential oils and vegetable substances on meat productivity and nutritional value of broiler chicken meat has been studied in the paper. The level of feeding and the quality of the feed consumed by poultry has a big infl uence on meat productivity. The use of our selected vegetable feed additive based on essential oils and vegetable substances increase the slaughter weight by 9,0–13,7 %, the slaughter yield by 2–5 %, the amount of muscle tissue and meat qualities of carcasses. The best results have been obtained by including the vegetable feed additive based on essential oils and plant substances in the amount of 0,015 % of the dry substance of the feed.
