Supplementation of papaya leaf extract in drinking water to optimize broiler chicken carcass production

Abstract

Abstract The papaya plant (Carica papaya Linn.) is regarded as an alternative option that is believed to have the potential to reduce fat accumulation in broiler chickens. In society, papaya leaves are well-known as ingredients in traditional medicine due to their content of alkaloid compounds and proteolytic enzymes, namely papain and chymopapain, which play a significant role in digestion and facilitate intestinal activity. The impact of adding Papaya Leaf Extract (PLE) to drinking water on parameters such as final body weight, carcass weight, carcass percentage, abdominal fat weight, and abdominal fat percentage is sought to be assessed in this study. Eighty-seven-day-old chicks, irrespective of gender, constitute the subjects of the research. Commercial feed, papaya leaves, research facilities and equipment, and manual and digital scales are utilized in the study. An experimental approach with a Completely Randomized Design (CRD) is followed in the research methodology. Five treatments, each repeated four times, are included in the study: T0 (control with 1 liter of drinking water), T1 (T0 + 5 ml of PLE), T2 (T0 + 15 ml of PLE), T3 (T0 + 25 ml of PLE), and T4 (T0 + 35 ml of PLE). Chicken slaughtering is performed after 35 days of rearing, with samples taken randomly from pens 1-20 and subsequently processed, adhering to Islamic principles. Measured parameters include final body weight, carcass weight, carcass percentage, abdominal fat weight, and abdominal fat percentage. Analysis of variance (ANOVA) in a Completely Randomized Design is employed for data analysis. The research findings suggest that providing papaya leaf extract to broiler chickens up to 35 days of age does not significantly affect final body weight, carcass weight, carcass percentage, abdominal fat weight, or abdominal fat percentage. Based on the results obtained from the broiler chicken carcass production in this study, the administration of PLE to broiler chickens can be conducted.
