Effect of Different Dietary Levels of Untreated and Copper Sulphate Treated Mustard Oil Cake (Brassica campestris) on Growth Performance and Nutrient Utilization of Broiler Chickens

Abstract

An experiment was conducted to study the growth performance and nutrient utilization of 280 numbers of day old broiler chicks for 42 days, which were randomly divided into equal seven groups with two replicates and offered ad lib diets containing no MOC (T₁) or untreated MOC and CuSO₄ treated MOC (@ 8g/kg) at 10 (T₂ and T₃), 15 (T₄ and T₅) and 20 % (T₆ and T₇) levels respectively.  Body weight gain (g) were significantly (P<0.01) higher in T₃ and T₅ group while significantly lower (P<0.01) gain was found in T₄, T₆ and T₇ group than control. Highly significant (P<0.01) differences was observed in FCR among the different treatment groups and no significant difference was observed in digestibility of organic nutrients. The study conclude that MOC treated with CuSO₄ @ 8g/kg meal can be incorporated in the diet of broiler chicken upto 15 % level with a distinct economic advantage.
