Abstract |
The goal of the study was
to investigate the influence of in ovo injection of omega-3 fatty
acids on performance traits, blood parameters and immune response in
broilers. At day 14 of incubation, 124 fertilized eggs (31 eggs for each
group) were injected with different levels of omega-3 fatty acid (0.05,
0.1 and 0.15 ml) and one was kept as a control. After hatching, 108
chicks were distributed into four groups (27 chicks for each group) and
each group was subdivided into three replicate (9 chicks for each
replicate). Results revealed that in ovo injection with omega-3
fatty acids on 14 day of incubation resulted in significant increase in
the hatchability and final body weight. Haematology (WBC, RBC, PCV, Hb)
improved significantly in treated chicks as compared with control
chicks. Furthermore, immune response of chicks treated with mega-3
against ND disease increased significantly compared with non-injected
chicks. In conclusion, in ovo feeding of omega-3 fatty acids, at
the levels of 0.05,0.1 and 0.15 ml resulted in a significant improvement
in production traits, haematological parameters and immune response in
broiler.
