ALIMOHAMMADI SARAEI, MH; SEIDAVI, AR; DADASHBEIKI, M  e  EDENS, FW. Response of plasma constituents and body measurement in broiler chickens fed fish oil and green tea powder. Arch. med. vet. [online]. 2016, vol.48, n.1, pp.61-68. ISSN 0301-732X.  http://dx.doi.org/10.4067/S0301-732X2016000100008.

An experiment was conducted to examine the influence of the dietary supplementation of fish oil (0, 15, or 20 g/kg), green tea powder (0, 10, or 15 g/kg), or their factorial treatment arrangements on selected blood chemical components in 42 days old broiler chickens. Fish oil as a main effect was not significant for any blood component except for decreased plasma uric acid, when fish oil was fed at 20 g/kg. Green tea powder at 15 g/kg in the diets was found to cause a significant increase in plasma uric acid, but in combination with fish oil, the plasma uric acid was lower than with 15 g/kg green tea powder alone. Green tea powder at 15 g/kg caused a significant decrease in plasma LDL, which was attributed to a significant decrease in plasma LDL/ HDL ratio. Use of green tea appeared to have the potential to improve antioxidant status due to increased plasma uric acid and improved plasma lipid profile due to decreased LDL. In general, performance traits of broilers fed green tea powder with and without fish oil decreased, which was attributed to the decrease in feed intake and decreased energy and protein efficiencies.
