Pathological alterations in broiler chickens fed with treated and untreated mustard oil cake

Abstract

Mustard oil cake (MOC) contains glucosinolates, due to which it cannot be incorporated in the diet of broiler chicken at a higher level. An experiment was designed to study the effect of different levels of treated and untreated mustard oil cake (MOC) on histopathology in broiler chickens. Two hundred and eighty day old commercial broiler chicks were divided randomly into 7 groups of 40 each with two replicates of 20. Seven different iso-caloric and iso-nitrogenous diets were prepared for both starter and finisher stage containing 0, 10, 15 and 20% copper sulfate (8g/kg copper sulfate) treated and untreated mustard oil cake. Thyroid gland weight was highest (10.13±0.08mg/100g body weight) in the group that was fed diet which contained 20% untreated MOC comparing to the other groups where 10 and 15% treated and untreated MOC was incorporated in the diet. Microscopically, 10 and 15% incorporation of untreated MOC in the diet caused mild changesin intestine, liver and kidneys, whereasbirds fed 20% levels of both treated and untreated MOC showed severe changes in these organs.
