Larval weight was weekly monitored, and the chemical composition of larvae and residual substrates was analyzed at the end of the experiment. Larvae fed CTL and BBP grew more than those fed MSL and MSH (p < 0.001). Feed intake was greatest for BBP (p < 0.001), and consequently, feed-to-gain ratio (F:G) was better for larvae fed CTL than BBP, and better for BBP than MSL and MSH (p < 0.001). Besides, total production of crude protein and ether extract were greater for CTL and BBP than for MSH and MSL (p < 0.001). The inclusion of bread by-product in the substrate did not affect growth performance, whereas diets including maize silage impaired larval growth, substrate intake, and F:G. Both by-products can be advantageously used for feeding T. molitor larvae, but the impairments in growth performance should be considered to optimize production costs. info:eu-repo/grantAgreement/ES/UZ-OTRI/2018-0406 info:eu-repo/semantics/openAccess by https://creativecommons.org/licenses/by/4.0/deed.es 2.7 2024 VETERINARY SCIENCES 21 / 170 = 0.124 2024 Q1 T1 AGRICULTURE, DAIRY & ANIMAL SCIENCE 15 / 86 = 0.174 2024 Q1 T1 0.733 2024 Veterinary (miscellaneous) 2024 Q1 Animal Science and Zoology 2024 Q1 5.2 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Remiro, Ana Remón, Sara Universidad de Zaragoza (orcid)0000-0002-2147-9263 Fondevila, Manuel Universidad de Zaragoza (orcid)0000-0002-0712-1185 2008 700 Universidad de Zaragoza Dpto.
