Abstract
This research examined how productive, physiological, and meat quality characteristics are affected by thyme oil Nano chitosan-Encapsulated (ETEO).The control group (T1) consumed the basal diet without supplementation, while the second and third groups fed control with Thyme essential oil (TEO) at 50 mg/kg diet (T2) or 70 mg/kg diet (T3). Finally, the fourth and fifth groups fed control +ETEO at 30 mg/kg (T4) and 50 mg/kg (T5) until 42 days of age. Compared to the control group, quails given a (T4) diet had the greatest body weight (BW), feed intake (FI) at 28 days, crude protein (CP) intake, and metabolizable energy (ME) intake from 7 to 42 days old. In terms of meat quality, the T4 and T5 groups had considerably lower TBARS levels (P<0.05) than the control and other groups. Control quail meat (thigh and breast) had the lowest total volatile basic nitrogen (TVB-N) (P<0.05), whereas T4 had the lowest quantity. The supplements improved blood total antioxidant capacity (TAC) in birds fed (T3) relative to (T2) and the control group. Both T2 and T3 showed considerably decreased circulating low-density lipoprotein (LDL) (P<0.05). T4 and T5 feeding increased TP and G levels considerably. As conclusion: Chitosan Nano-Encapsulation could be a method for retaining compounds, properties, and effects of the essential oils used in low concentrations and improving the meat quality of quails.
