Dietary fatty acid composition in broiler influences carcass quality by altering fat deposition and fatty acid profile. The quality of the fatty acids profile and the levels of various nutrients reflect the components of the rations provided to the birds. Thus the study was carried out to evaluate the effect of incorporation of rapeseed oil in broiler ration on fatty acid concentration of carcass in broiler chicken. A 160 day-old straight run broilers (Vencobb 400) chicks were randomly allotted into four treatment groups with four replicates of ten chicks each (G1, G2, G3 and G4). The basal diets (G1) were prepared to meet Bureau of Indian Standards nutrient requirements (IS 1374; 2007) included at the rate of 1.5, 3, and 4.5 per cent in pre-starter, starter and finisher ration, respectively. The experimental broiler rations prepared with rapeseed oil replacing 25, 50 and 100 per cent of palm oil in basal diets in treatment groups. Six birds were randomly selected from each group and slaughtered on 42nd day to study fatty acid concentration of carcass.Saturated fatty acid (SFA) concentration is significantly higher (P<0.01)in breast and thigh muscles in G1 group birds and lowest in G4 group. Whereas, concentration of poly-unsaturated fatty acid (PUFA) in G3 and G4 group thigh muscles were significantly higher than the G1 group. Mono unsaturated fatty acid concentration was not significantly affected between the groups. Incorporation of rapeseed oil in broiler ration increases deposition of PUFA content in the broiler carcass with no adverse effects

From the results of this study, incorporation of rapeseed oil in broiler ration increases deposition of PUFA content in the broiler carcass with no adverse effect which is a desirable character of consumer’s preference. Thus, considering more availability and comparable cost of rapeseed oil, it is suggested that rapeseed oil could be included in broiler pre-starter, starter and finisher diet at 1.5, 3.0 and 4.5 % respectively as an energy source to increase PUFA composition which do favorable impact on consumer health.
