Effect of Dried Mealworms (), Larvae and Olive Leaves ( L.) on Growth Performance, Carcass Yield and Some Blood Parameters of Japanese Quail ().

The aim of this study was to investigate the effect of meal (TM) and/or olive leaf powder (OL) supplementation to quail diet on animal performance, carcass yield and some blood parameters. One hundred and forty-four 1-day-old Japanese quails (body weight: 29.9 ± 0.46 g) were divided 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 were provided . The results showed that TM and OL inclusion promoted quail body weight at 5 weeks of age; = 0.001. Feed conversion ratio (FCR) of G3 was significantly ( < 0.01) reduced compared 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 not influenced 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 no adverse effects on growth performance, carcass constituent yields and serum constituents.
