Growth performance, serum biochemistry and meat quality traits of Jumbo quails fed with mopane worm () meal-containing diets.

Alternative protein sources such as mopane worm () meal (MWM) are essential for sustainable poultry production. To date, no studies have attempted to investigate the effect of replacing soybean products with MWM in Jumbo quail diets. Thus, this study was designed to investigate the optimum inclusion level of MWM in place of soybean products on feed intake, physiological and meat quality responses of Jumbo quails. A total of 384 two-week-old mixed-gender quails (71.2 ± 5.40 g live-weight) were allotted to four isoproteic and isocaloric dietary treatments formulated by replacing soybean products with MWM at 0 (MWM0), 50 (MWM5), 100 (MWM10), and 150 (MWM15) g/kg. Neither linear nor quadratic effects () were observed for feed intake, physiological responses, carcass traits and internal organs except for large intestines, which linearly decreased () with MWM levels. There were significant quadratic trends for meat redness (), yellowness () and chroma values in response to MWM levels. No dietary influences () were observed on feed intake, physiological responses, internal organ weights, and carcass and meat quality parameters, except on *, chroma and shear force. Diets MWM5 and MWM10 promoted higher () * and chroma values than MWM0. Whereas diet MWM5 promoted the highest () shear force (2.39 N) than diets MWM0 and MWM10. We concluded that MWM has the potential to replace soybean products in quail diets without compromising their performance, health and meat quality. An optimum MWM inclusion level could not be determined suggesting that higher levels of MWM should be further investigated.
