Effects of oxygenated or hydrogenated water on growth performance, blood parameters, and antioxidant enzyme activity of broiler chickens

Abstract:

This study was conducted to investigate the effects of providing oxygenated and hydrogenated water on the growth performance, blood biochemical parameters, and immunoglobulin concentrations and antioxidant enzyme activity of broiler chickens. In our investigation, 144 Ross × Ross broiler chicks were randomly allotted to three different treatment groups with four replicates (treatment × replicate × bird = 3 × 4 × 12). All chicks were given one of the following types of water for five weeks: tap water (CON), hydrogenated water (HNW), and oxygenated water (ONW). ONW supplementation increased the final body weight and weight gain and also improved both feed intake and feed conversion of broiler chickens as compared to those of CON broiler chickens (P < 0.05). The abdominal fat and its ratio to the final body weight showed that fat accumulation in the broiler chicken abdomen was reduced when broiler chickens drank only ONW for five weeks (P < 0.05). ONW supplementation improved blood parameters, including triacylglyceride, total cholesterol, and low-density lipoprotein-cholesterol. Additionally, in accordance with a globulin increase in broiler chickens, both IgG and IgM generation were significantly enhanced when ONW was supplied to broiler chickens (P 0.05). Both oxygenated and hydrogenated water supplementation significantly improved the antioxidant effects (P < 0.05), and it seems that superoxide dismutase refinement was completed due to oxygen and/or hydrogen enhancement of drinking water. These results indicate that oxygen enhancement of drinking water may be recommended to improve growth performance by increasing immunoglobulins mainly IgG and IgM.
