Abstract:
This experiment was conducted to examine the effects of Tenebrio molitor (TM) larvae meal inclusion in diets as a replacement for fish meal and soybean oil on growth performance, carcass traits, meat quality, and intestinal morphology of Japanese quails (Coturnix japonica).A total of 160 mixed sex quails at seven-day of age were weighed and allocated to 20 cages. The dietary treatments were as follows: control (C) group containing 370 g soybean meal (SBM)/kg of diet and 30 g fish meal (FM)/kg of diet and four T. molitor (TM) larvae meal groups, in which TM meal was included as a replacement for FM and soybean oil at 7.5 (7.5), 15 (TM15), 22.5 (TM22.5) and 30 (TM30) g TM/kg of diet. The use of TM at the levels of 22.5 and 30 g/kg of diet significantly (P < 0.05) increased body weight (BW) of the birds compared with other groups. Quails fed 22.5 and 30 g TM/kg of diet had better FCR values compared with other groups. The carcass and breast yields obtained in birds fed 30 g TM/kg of diet was significantly (P < 0.05) higher than other groups. Significant increases in villous height and crypt depth in TM supplemented birds was found (P < 0.05). Water retention capacity, redness and yellowness were improved by TM meal supplementation (P < 0.05). In conclusion, our data indicated that increasing TM inclusion up to 30 g/kg of feed in quail diets could improve BW, FCR, carcass yield, meat quality, and histology of jejunum.
