Abstract
Broiler meat consumption in the world increases annually with the development of modern diet pattern. Saturated fatty acid content of the meat causes high risk of cardiovascular disease in human. Fish is an important source of omega-3 fatty acids, which reduce the risk of cardiovascular disease in human. However, access to food fish, which are rich in omega-3 fatty acids, is questionable for many people in the world. Fortunately, studies revealed that the dietary enrichment of broiler chicken ration with omega-3 fatty acids enriched the broiler chicken meat with omega-3 fatty acids. Hence, consumption of such broiler chicken meat may supplement the scarcity of consumption of omega-3 fatty acids rich foods viz. fish. Moreover, dietary enrichment of omega-3 fatty acids improves carcass by reducing the abdominal fat deposition in broilers. However, shelf-life of broiler chicken meat that is enriched with omega-3 fatty acid is low due to high levels of lipid oxidation. However, usage of antioxidants improves the shelf-life of omega-3 fatty acid enriched broiler chicken meat.
Highlights
Animal source foods are complete and nutrientdense, and provide high quality protein and bioavailable micronutrients viz. iron, zinc vitamin A, vitamin B12 and calcium, for children and pregnant and lactating mothers (FAO, 2011).In particular, consumption of meats prevents anaemia and enhances iron absorption from plant based foods(Walker et al, 2005)
Absorbed dietary fat is packed into portomicrons and non-esterified fatty acids which pass directly into the hepatic portal blood supply, whereas fat synthesized in the liver is transported to other tissues in the form of triglyceride-rich very low density lipoprotein(Tùmová and Teimouri, 2010).Since dietary omega-3 poly-unsaturated fatty acids (PUFAs) lowers the low-density lipoprotein (LDL) levels in blood stream of broiler chickens, fat deposition may be reduced
Enrichment of broiler chicken meat with omega-3 PUFA is possible through dietary treatment
Summary
Animal source foods are complete and nutrientdense, and provide high quality protein and bioavailable micronutrients viz. iron, zinc vitamin A, vitamin B12 and calcium, for children and pregnant and lactating mothers (FAO, 2011). Dietary enrichment of broiler chicken meat with omega-3 fatty acids intramuscular fat deposition. Fish oil (Lopez-Ferrer et al, 2001; Basmacýoðlu et al, 2003; Mirghelenj et al, 2009) into broiler chicken diet enriched the chicken meat with omega-3 PUFAs (Hargis and Van Elswyk, 1993; Leskanich and Noble, 1997; Moghadasian, 2008; Zuidhof et al, 2009; Zduñczyk and Jankowski, 2013).Table 2 shows that different sources of long-chain (LC) n-3. Absorbed dietary fat is packed into portomicrons and non-esterified fatty acids which pass directly into the hepatic portal blood supply, whereas fat synthesized in the liver is transported to other tissues in the form of triglyceride-rich very low density lipoprotein(Tùmová and Teimouri, 2010).Since dietary omega-3 PUFA lowers the low-density lipoprotein (LDL) levels in blood stream of broiler chickens, fat deposition may be reduced.
