Abstract :
[en] The aim of this study was to investigate the effect ofTenebrio molitormeal (TM) and/or oliveleaf powder (OL) supplementation to quail diet on animal performance, carcass yield and some bloodparameters. One hundred and forty-four 1-day-old Japanese quails (body weight:29.9±0.46 g) weredivided into four groups of 36 chicks, receiving four different diets, i.e., G1: Standard commercial(SCD); G2: SCD + 3% TM; G3: SCD + 3% OL; and G4: SCD + 3% TM + 2% OL. Feed and water wereprovidedad-libitum. The results showed that TM and OL inclusion promoted quail body weight at5 weeks of age;p= 0.001. Feed conversion ratio (FCR) of G3 was significantly (p< 0.01) reducedcompared to the other groups. Overall mortality was not different, at around 6.25%, between groups.Carcass [(71.5–74.3%)], gizzard [(2.5–2.7%)], heart [(1.1–1.2%)] and giblet [(6.8–6.9%)] yields were notinfluenced by the diet. No significant effect of the diet was observed for serum proteins, creatinine,urea and lipids. To conclude, the mixture of an incorporation of TM and OL in quail diet showed noadverse effects on growth performance, carcass constituent yields and serum constituents
