title: Color and fatty acid profile of abdominal fat pads from broiler chickens fed lobster meal.
abstract: Consumer demands for food products enriched with healthful n-3 fatty acids are steadily increasing. Feeding marine byproducts may provide an economical means of increasing the long-chain n-3 content of broiler tissues. A study was conducted to evaluate the effect of dietary lobster meal (LM) on the color and fatty acid profile of broiler chicken fatty tissue. Broilers were fed increasing levels (0, 2, 4, 6, 8, and 10%) of LM for 35 d. Fat pad samples were collected at slaughter and color and fatty acid concentrations were determined. A linear effect was found of LM on red coloration (P < 0.05) as dietary LM increased. Fat pad eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) levels also increased (P < 0.0001) in a linear fashion. The essential long-chain fatty acids were lower for the 10% LM diet (0.37 mg of EPA/g; 0.16 mg of DHA/g) compared with the 8% LM diet (0.51 mg of EPA/g; 0.27 mg of DHA/g). Using lobster meal as a feed ingredient resulted in broiler abdominal fat pads with a favorable increase in n-3 fatty acids.
