A study with a duration of 42 days was conducted to evaluate the influence of fish oil inclusion on performance parameters, serum lipid content, antibody responses to sheep red blood cells (SRBC) and the composition of antigen and meat fatty acids in broilers. Two hundred and sixteen 1-day-old broiler chicks from a commercial hybrid (Cobb 500) were allocated randomly to four groups, which received feed supplemented with 1.5%, 3.0% and 6% fish oil or feed that was not supplemented (control group).
