Effect of supplementing different concentrations of organic trace minerals on performance, antioxidant activity, and bone mineralization in Vanaraja chickens developed for free range farming.

An experiment was conducted to determine the performance, antioxidation activity, and bone mineral content in Vanaraja chickens fed diet supplemented with organic trace minerals (oTM) at reduced levels. A total of 360 day-old chicks were selected and distributed randomly into 60 battery brooder pens. A maize-soybean meal-based control diet was supplemented with inorganic trace minerals (iTM), i.

Effect of supplementing organic selenium on performance, carcass traits, oxidative parameters and immune responses in commercial broiler chickens.

An experiment was conducted to determine the effect of supplementing various concentrations (0, 100, 200, 300, or 400 μg/kg diet) of organic Se on growth performance, carcass traits, oxidative stress, and immune responses in commercial broiler chickens reared in open-sided poultry house under tropical climatic conditions. Each diet was fed ad libitum to eight replicates consisting of six birds in each pen from 1 to 42 d of age. Body weight gain and feed efficiency, and relative weight of liver, abdominal fat and ready to cook yields were not affected (p>0.
