Pengaruh Penambahan Ekstrak Kulit Buah Naga (Hylocereus polyrhizus) pada Air Minum terhadap Performans Ayam Broiler

Abstract

Broiler chicken (Gallus domesticus) is one of the warm-blooded animals that does not have complete sweat glands on its body and is susceptible to environmental temperature heat stress. The resulting impact is that chickens are easily stressed and can trigger free radicals. Giving additives in the form of antioxidants is one of the efforts that can be made to overcome oxidative stress due to high environmental temperature stress. Antioxidants are compounds that can inhibit the oxidation reaction process in the body by replacing ions and neutralizing free radicals to become more stable. To overcome this, there is an interest in using natural ingredients from natural resources as antioxidants in broiler chickens. Dragon fruit peel (Hylocereus polyrhizus) is known as part of fruits that have high antioxidant effectiveness compared to the pulp. The effect of the addition of Dragon Fruit Peel Extract as a natural antioxidant will be observed in broiler performance which includes feed consumption, body weight gain and feed conversion. Maintenance is differentiated based on starter and finisher phases and maintained for 35 days. The treatments used in the study were dragon fruit peel extract with various concentrations, namely P0 (0%), P1 (7.5%), P2 (15%) and P3 (22.5%) added to the broiler drinking water. Observations of performance results were observed using the Complete Randomized Design (CRD) method and further tested using the 5% Duncant Test. Based on the results showed that the treatment of extracts using P1 (7.5%) concentration produced the best average results, namely feed consumption (89.68 ± 1.214), body weight gain (51.09 ± 0.85) and feed conversion (1.755 ± 0.04).
