The effect of Piliostigma thonnigii aqueous leaf extracts on broiler carcass fat and antioxidant levels
Piliostigma thonningii is a plant that has been found to contain a number of phytochemicals, including phenols. Phytochemicals have among other properties cholesterol lowering and anti¬oxidant ability. This experiment was aimed at evaluating the effect of including different levels of Piliostigma thonningii aqueous leaf extracts on carcass fat and blood phenolic levels of Cobb 500 broilers. The experiment was conducted at the University of Zambia, School of Agricultural Sciences over a period of five (5) weeks. The experiment was done in a Randomised Complete Block Design with six treatments, of which two were controls and three replicates. Ninety (90) broilers were randomly distributed among the treatments. The birds were given Piliostigma thonningii leaf extract-containing drinking water at levels; lOOg, 200g, 300g and 400g leaf material per 200Kg bird live weight. No significant differences (P<0.05) were found among the treatments.
