This study evaluates the effects of Tenebrio molitor meal (TMM) as an alternative to conventional plant-based (soybean meal, SBM) and animal-based (fishmeal, FM) protein sources on blood parameters, growth slaughter performance, carcass traits, meat quality feedlot lambs. A total 24 Suffolk lambs [3 months age, 21.4 ± 1.08 kg body weight (BW)] were allocated for 60 days three treatments (8 per treatment) in a completely randomized design, follows: 1- SBM at 150 g/kg dry matter (DM)], 2- FM 50 DM, 3- TMM DM. Feed intake, BW, samples collected 0, 20, 40, 60. At end trial, slaughtered evaluation assessment. The average daily gain was higher SBM-fed than TMM-fed (0.25 0.21 kg/d; P < 0.001). Plasma levels creatinine FM-fed when compared lambs, while showed intermediate values (88.72, 85.69 87.57 μmol/L, respectively; 0.05). hot cold weights (15.99 15.52 vs 18.49 18.03 kg) yields (44.31 43.02 % 46.03 44.87 %) lower group with (P dietary treatment had no effect > 0.05) pH, color, texture, water loss contents fat, protein, moisture. Further research should evaluate optimal inclusion combination avoid negative economic implications.

Artificial Diets as Viable Substitutes for Host Plants in the Growth of Locusta migratoria

Entomological Research, Journal Year: 2025, Volume and Issue: 55(4)

Published: April 1, 2025

ABSTRACT This study examined the growth and developmental responses of Locusta migratoria nymphs to different artificial diet formulations explored efficient feeding strategies optimize their performance. The formulated with wheat bran fish meal (WF) was more suitable for L. than other diets, supporting improved survival. Contrastingly, casein‐ sucrose‐containing diets (WCS) demonstrated higher cannibalism rates lower Further ratio optimization in WF that + 8% (WF8) provided most survival balance. WF8 exhibited slightly feed efficiency weight gain natural host plants, corn; however, period comparable. indicated WF8's potential as a promising alternative diet. Particularly, transitioning from fourth instar after plants until third led substantially adult body continuous on single These results establish provide valuable insights into sustainable large‐scale insect farming. supports development production systems promotes advancement edible industry an protein source.
