Abstract

In a study that investigated the effects of monosodium glutamate on the hormonal profiles, haematological and serum biochemical indices, 300 sexually mature barred Plymouth rock cocks were randomly divided into six experimental diets containing MSG at 0.00, 0.25, 0.50, 0.75, 1.00 and 1.25 g/kg diet. Each group was replicated five times with ten birds per replicate. The birds were fed ad – libitum and clean water was provided regularly for a period of 16 weeks. Serum protein, hormones, electrolyte balance, metabolites, lipid profiles and enzymes were evaluated. Inclusion at 0.75 g/kg diet and above significantly (P<0.05) influenced the serum proteins, enzymes, lipids, Na+ concentration, metabolites and antioxidant status of the cocks adversely. There was significant (P<0.05) elevation of the serum corticosterone concentration while there was a significant (P<0.05) decrease in other growth and reproductive hormonal responses at the same level of inclusion. It can be concluded that inclusion of dietary MSG up to 0.50 g/kg could be utilized in cocks’ diets to enhance palatability without any deleterious effect on the birds and their products.
