The effects of Papain Crude Extract Addition in Diets on Broilers Production Performances

Abstract

This study was conducted to evaluate the effects of papain crude extract addition in mash and pellet feed forms on production performance of broiler chickens in order to obtain the best level of extract papain in mash or pellet form. This natural protease enzyme was extracted from unripe papaya. A complete random design was applied in this study and it was arranged with factorial 4*2 and three replications. The treatments were 4 levels of papain (0, 0.03, 0.05, and 0.07 %) and two physical forms of feed (mash and pellet). Broilers production parameters measured were: feed intake, body weight, feed conversion ratio (FCR) and carcass percentage. The results of analysis of variance showed that the interaction was highly significant (P<0.01) for feed intake, body weight, carcass percentage respectively while feed conversions have significant interaction (P<0.05). The significant differences in the feed consumption described the role of papain enzyme through treatment of CEP and the physical form of feed. The results indicate that the all treatment of papain crude extract level both in mash and pellet feed form were able to improve feed intake, body weight, FCR and carcass percentage of broiler chickens, whereas the best performance was obtained in the treatment of 0.05% papain crude extract in mash form of diets.

Penelitian ini dilakukan untuk mengetahui lebih dalam efek penambahan ekstrak kasar papain dalam pakan berbentuk mash dan pellet terhadap penampilan produksi broiler. Enzim protease alami ini diekstrak dari pepaya muda. Rancangan acak lengkap diterapkan dalam penelitian ini yang disusun secara faktorial 4 * 2 dan tiga ulangan. Perlakuan yang diberikan adalah 4 tingkatan papain (0, 0,03, 0,05, dan 0,07%) dan dua bentuk fisik pakan (mash dan pelet). Parameter poduksi broiler yang diukur adalah konsumsi pakan, berat badan, rasio konversi pakan (FCR) dan persentase karkas. Hasil analisis varians menunjukkan ada interaksi yang sangat signifikan (P<0,01) menyangkut konsumsi pakan, berat badan dan persentase karkas masing-masing, sementara konversi pakan menunjukkan interaksi yang nyata (P<0,05). Perbedaan yang signifikan dalam konsumsi pakan menggambarkan peran enzim papain melalui perlakuan CEP dan bentuk fisik pakan. Hasil menunjukkan bahwa semua perlakuan tingkat ekstrak kasar papain baik di mash dan pakan pelet bentuk mampu meningkatkan konsumsi pakan, berat badan, FCR dan persentase karkas ayam broiler, sedangkan performan terbaik diperoleh pada perlakuan 0,05% papain ekstrak kasar dalam pakan berbentuk mash.

Influence of exogenous acid protease in broiler chickens fed corn–soybean meal‐based diets

“…Similar to these previous studies, our findings showed that dietary supplementation of acid protease in corn-soybean meal-based diets linearly increased BWG and decreased the FCR during 18 to 35 days and overall. Rumokoy et al, (2016) also demonstrated that all treatment level (0.03, 0.05 and 0.07%) of papain crude extract (a proteolytic enzyme that can break down peptide bonds of a protein molecule) improved the BW, feed efficiency and carcass performances of broilers than the performances of animals consumed the diets without any papain. Additionally, there was a main effect of protease on FCR with birds fed diets with protease having a lower FCR than those without (Vieira et al, 2013;walk et al, 2018 had a positive effect on broiler performance and feed efficiency.…”
