Changes in metabolic nutrients utilization and alterations in biochemical and haematological indices in broilers fed graded levels of dietary Moringa oleifera

Abstract

Graded levels of full-fat undecorticated Moringa oleifera seed meal (MOSM) were evaluated in diets of 96-day old broilers at 2.5, 5.0 and 7.5% while a maize-soybean diet was used as a reference diet. Nutrients utilization by the broilers and effects of the virgin dietary MOSM on serum chemistry, haematology and some bio-data- protein efficiency ratio (PER) and nitrogen metabolism (NM) were used as response criteria for the evaluation. The metabolic utilization of nutrients, most of the serum chemistry and haematological parameters decreased in response to increasing dietary levels of MOSM except values on products of metabolism like creatinine, uric acid, bilirubin and conjugated bilirubin that tended to elevate with increasing levels of dietary unprocessed MOSM. Since no mortality was recorded in this experiment even at 7.5% MOSM inclusion, further research is on-going to determine the lethal level to poultry including other monogastric animals.
