Effect of replacement of soybean meal with canola and mustard meal on carcass characterstics and economics of broiler production

Six week feeding trial was conducted to study the carcass characteristics and economics of production on replacement of soybean meal with different levels of canola or mustard meal. A total of 196 day old commercial (Vencob) broiler chicks were subjected to 7 isocaloric and isonitrogenous dietary treatments in which maize soybean based ration was used as a control diet and in 6 test diets either canola or mustard meal replaced the soybean meal at 10, 15 and 20% level on equal nitrogen basis. Results showed that neither canola nor mustard meal at any level had significant effect on evisceration rate. In comparison to control, on per unit live weight basis margin of receipt over feed cost was higher in canola and lower in mustard supplemented groups. The margin of receipt was higher in all levels of canola meal compared to mustard meal. It was concluded that for partial replacement of soybean meal the canola meal is more economical and better alternate to mustard meal due to its lower glucosinolate and erucic acid content and higher level of essential amino acids.
