Effects of additives mannan and β-glucan as a prebiotics on broilers diets contaminated with aflatoxin [electronic resource].

Includes references.

This study was carried out to determine the effects of different levels of mannan and β-glucan as a prebiotics on some liver and kidney function, blood parameters, immune globulins concentration and body weight on broilers fed diets contaminated with lmg aflatoxin I kg diet. Eighty broilers were randomly distributed into eight similar groups each group fed commercial broiler diet as the follows {negative control group fed an regular broilers ration free from prebiotics and aflatoxin, posative control group fed diet contaminated with aflatoxin (lmg/kg) and free from prebiotics, groups from 3 to 8 fed diet contaminated with aflatoxin (lmg/kg) and contain different concentration of mannan and β-glucan in premix (premix added as a 1.5 gm/kg diet)}. Results showed that positive control signlflcantly Increased (P < 0.05) serum glutamlcoxaloacetic transaminase (SGOT) and serum glutamicpyruvic transaminase (SGPT), compared with negative control and the best effect of adding man nan and p-glucan recorded with group 5, 6 where the results were close of negative control. The same trend recorded with results obtained from serum urea and creatinine. Results of hematological analysis showed that positive control caused a significant decrease (P < 0.05) in values of packed cell volume (PCV), Red blood cells counts (RBC), Hemoglobin (Hb), and noticed a significant increase (P < 0.05) occurrence in values of total white blood cell (WBC). Generally the addition of mannan and p-glucan to diets contaminated with aflatoxin significantly improved the adverse effects of aflatoxin on hematological parameters. This study demonstrates an increase in serum IgGs concentrations with positive control and groups without significant differences with negative control or other groups. The average body weight gain (g) increased (P < 0.05) with broilers fed negative control diet compared with positive control. The addition of both mannan and β-glucan to diets led to improvement in increase body weight gain and decreases in relative liver whight ratio.
