Abstract
Oxidative stress caused by excessive levels of reactive oxygen species that are induced under stressful environments such as heat exposure and coccidiosis has been regarded as one of the major factors negatively affecting the performance of birds in the concentrated poultry industry.
Antioxidants are substances which prevent oxidation and decrease oxidative damage occurred from reactive oxygen species and free radicals inside the living cell.
Tocotrienol is a strong antioxidant, with an unsaturated isoprenoid chain, it can protect cytochrome P-450 from oxidative damage 6.5 times more than tocopherol and it is the main component of palm oil.
The current study was carried out to evaluate the possible amelorative effects of tocotrienols (primary form of vitamin E) and selenium yeast against the adverse effect of florfenicol through the determination of growth performance parameters (body weight, body weight gain, feed consumption and feed conversion ratio), serum biochemical parameters, antioxidant activity in liver and kidney and histopathological impact.
One hundred and fifty, one-day-old, unsexed Cobb chicks were used. Chicks were leg banded and individually weighed.
