In poultry,feed based on maggots,like larvae of black soldier fly(Hermetia illucens) is an attractive option to substitute current ingredients which are expensive and often in direct or indirect competition with human food.Little information is currently available on the utility of these larvae in poultry feed,so goals of this study were to determine whether larvae could be reared on horse manure under traditional farming conditions and to evaluate the growth performances of a local poultry fed these larvae and the fatty acids profiles of their meat.After freezing and thawing,larvae were introduced in the feed of Ardennaise chickens between 30 and 80 days of age.Birds in the control group received a commercial standard feed,while those in the treatment group received the same commercial feed in which 8% was substituted with whole fresh larvae corresponding to 2% on a dry matter basis.Means ± standard errors of larval length and weight were 20.67 ± 2.21 mm and 0.14 ± 0.02 g,respectively.Mean larval percentages of dry matter and of substances extractable in diethyl ether were 24.6% and 23.1%,respectively.Larval fatty acids profiles were predominantly composed of lauric acid(28.1%) and palmitic acid(22.0%).Least squares means of weekly weights of chicken,adjusted for the effects of sex,replication and initial weights,were significantly higher(P < 0.05) by 77.03 ± 53.37 g in larvae-fed than in control chickens.All other measurements were not statistically different between larvae-fed and control chicken,including fatty acid profiles,protein content and w6/w3 ratio.
