Abstract

1. The objective of this experiment was to determine and compare the apparent lipid digestibility coefficient and apparent metabolisable energy (AME) value of shea nut (Vitellaria paradoxa, Gaertn.) fat in broiler chickens with that of soybean oil and cocoa fat. 2. One hundred and sixty 13-d-old male broiler chicks were used in a randomised complete block design. The fats were added at 30, 60 and 90 g/kg to a basal diet. A tenth dietary treatment was the basal feed with no added fats or oils. The birds were fed on the diets for 8 d and all droppings were collected for the final 4 d. 3. The mean coefficient of apparent lipid digestibility for shea fat (0·58) was similar to that of cocoa fat (0·54) but lower than that of soybean oil (0·95). There was evidence of a lipid × concentration interaction with the 90 g/kg shea fat diet having low lipid digestibility (0·43). 4. There was an interaction between the effects of dietary lipid concentration and test lipid on AME but, at dietary levels of 60 g/kg and below, the AME of shea fat (22·0 MJ/kg DM) and cocoa fat (26·4 MJ/kg DM) was significantly lower than that of soybean oil (39·8 MJ/kg DM).
