摘      要：Background In contrast to protein-rich insect meal,the feed potential of insect fat is generally less explored and knowledge about the suitability of insect fat as a fat source specifically in broiler diets is still *** view of this,the present study aimed to comprehensively investigate the effect of partial(50%) and complete replacement of soybean oil with insect fat from Hermetia illucens(HI) larvae in broiler diets on performance,fat digestibility,cecal microbiome,liver transcriptome and liver and plasma ***,100 male,1-day-old Cobb 500 broilers were randomly assigned to three groups and fed three different diets with either 0(group HI-0,n cens(HI) larvae fat for 35 d.= 30),2.5%(group HI-2.5,n %(HI-5.0,n = 35) or 5.0= 35) Hermetia illuResults Body weight gain,final body weight,feed intake,and feed:gain ratio during the whole period and apparent ileal digestibility coefficient for ether extract were not different between *** microbial diversity did not differ between groups and taxonomic analysis revealed differences in the abundance of only four low-abundance bacterial taxa among groups;the abundances of phylum Actinobacteriota,class Coriobacteriia,order Coriobacteriales and family Eggerthellaceae were lower in group HI-5.0 compared to group HI-2.5(P 0.05).Concentrations of total and individual short-chain fatty acids in the cecal digesta were not different between the three *** transcriptomics revealed a total of 55 and 25 transcripts to be differentially expressed between groups HI-5.0 ***-0 and groups HI-2.5 ***-0,respectively(P 0.05).The concentrations of most lipid classes,with the exception of phosphatidylethanolamine,phosphatidylglycerol and lysophosphatidylcholine in the liver and cholesterylester and ceramide in plasma(P 0.05),and of the sum of all lipid classes were not different between *** Partial and complete replacement of soybean oil with HI larvae fat in broiler diets had no effect on gro
