Abstract

A total of 480 day-old broiler chicks were used in two trials conducted to investigate the performance and lipid contents of blood, liver and kidneys of birds when fed varying levels of palm kernel oil (0% and 2%) and biotin (40, 80, 120, 160, 200 and 240 mcg/kg feed) in a 2 x 6 factorial experimental design. The results showed that blood, liver and kidney lipid concentrations were significantly affected by dietary biotin treatments. While total lipid, free fatty acid, triglyceride and cholesterol contents were negatively correlated with dietary biotin level, phospholipid concentrations were positively correlated. Biotin-deficient chicks had significantly higher total lipid, free fatty acid, triglyceride and cholesterol but lower phospholipid contents in their blood and the two organs. Supplementation of the diet with 2% palm kernel oil significantly elevated blood phospholipid concentration, but depressed the accumulation of the other lipid fractions in both organs and the blood of birds. Blood, liver and kidney cholesterol concentrations were not affected by 2% fat supplementation. Observation on the lipid parameters coupled with the results on feed utilisation appeared to suggest that a minimum of 120 mcg of the vitamin per kilogram of diet was required by broiler chicks for optimum performance.
