A study was conducted to assess the effect of mannan-oligosaccharides (MOS) and fructo-oligosaccharides (FOS) either alone or in combination on serum biochemical profile and immunocompetence in meat-type quails from day old to 5 weeks of age. Nine experimental diets were prepared incorporating three levels (0, 1.0 and 2.0 g/kg diet) each of MOS and FOS in a factorial manner. Four hundred and five day-old quail chicks were distributed into 9 experimental groups of 45 chicks in each, with three replicates in each treatment. At the end of five weeks, blood was collected from six birds of each treatment and the serum was analyzed for total protein, total cholesterol and triglycerides. The results revealed that the quails from all treatment groups receiving MOS and /or FOS recorded lower serum cholesterol and triglycerides with higher total protein. However, differences between different treatments were statistically non-significant. The humoral immune response, as measured by haemagglutination inhibition antibody titer against Ranikhet disease at 2, 3 and 4 weeks post-immunization did not increase significantly with the dietary inclusion of MOS and/or FOS either alone or in combination. Therefore,mannan-oligosaccharides and fructo-oligosaccharides could not influence the blood biochemical and immune response in broiler quails.
