  1. *p < 0.05, **p < 0.01, ***p < 0.001—the reference group (BSFL) is significantly different within a row when asterisks are present. 1BSFL—basal diet with 100% black soldier fly (H. illucens) larval fat; 2SO—basal diet with 100% soybean oil; 3RO—basal diet with 100% rapeseed oil; 4PO—basal diet with 100% palm oil; 5PKFD—basal diet with 100% palm kernel fat distillate; 6PF—basal diet with 100% poultry fat; 7PL—basal diet with 100% pig lard; 8BT—basal diet with 100% beef tallow; 9SEM—standard error of the mean; 10BWG—body weight gain; 11FI—feed intake; 12FCR—feed conversion ratio.
  2. The means represent 10 pens of 15 birds each until 14 days and 10 birds from 15 days (n = 10).
  3. Analysis of variance (ANOVA) or the Kruskal‒Wallis test, depending on the normal distribution of the data, provides the probability level (P value) presented in the last column.
