The present study evaluated the effect of supplementation with oregano essential oil (OEO) on the productive parameters, oxidative stability, and lipid parameters of turkey meat. Eighty 1-d-old male turkeys were randomly distributed into four treatments groups and fed the following diets for 105 d: control diet without any supplementation or supplementation with 300 mg/kg lincomycin and spectinomycin, 100 mg/kg OEO, or 200 mg/kg OEO. Supplementation with 200 mg/kg OEO obtained the best body weight, average daily gain, feed conversion, and the lowest feed intake with respect to the other diets (p < 0.001), while 100 mg/kg OEO had the best oxidative stability (p < 0.001). Though OEO had no hypocholesterolemic effect, 200 mg/kg OEO produced the lowest concentration of triglycerides in the blood (p < 0.05). In conclusion, OEO supplementation improves productive parameters and increa...

Diets supplemented with halquinol and/or nanoencapsulated essential oils (N-EOs) have shown positive effects on the productive parameters of broiler chickens. However, there is limited comparative evidence between these two products. This study aimed to investigate and compare the efficacy of N-EOs blends with halquinol as dietary supplements for broiler chickens. A total of 500 male Cobb 500 broiler chickens were randomly assigned to five dietary groups. The control group received a conventional diet supplemented with halquinol (60%), while the experimental groups received supplementation with N-EOs blends derived from soursop (S), lemon (L), and eucalyptus (E) in different proportions: T1 (S:33.33%, L:33.33%, E:33.33%), T2 (S:50%, L:25%, E:25%), T3 (S:25%, L:50%, E:25%), and T4 (S:25%, L:25%, E:50%). The trial lasted for 42 days. The results showed that the T1 and T4 groups obtained th...
