Evaluasi Pemberian Tepung Daun Gedi (Abelmoschus manihot L.) dalam Ransum terhadap Organ Dalam dan Saluran Pencernaan Ayam Broiler

Abstract

Pelarangan antibiotic growth promoter (AGP) mendorong penggunaan fitobiotik alami, salah satunya tepung daun gedi (Abelmoschus manihot L.) yang mengandung senyawa bioaktif dan antioksidan. Penelitian ini bertujuan untuk mengevaluasi pengaruh pemberian tepung daun gedi (TDG) dalam ransum terhadap bobot organ dalam, saluran pencernaan, dan organ imunitas ayam broiler umur 35 hari. Sebanyak 200 ekor ayam broiler strain Cobb 500 dipelihara selama 35 hari menggunakan rancangan acak lengkap dengan 4 perlakuan dan 5 ulangan. Perlakuan terdiri atas P0 (0% TDG), P1 (1,5% TDG), P2 (3% TDG), dan P3 (4,5% TDG) dalam ransum. Data dianalisis menggunakan analisis ragam (ANOVA) dan dilanjutkan dengan uji Tukey. Hasil penelitian menunjukkan bahwa pemberian TDG hingga level 4,5% tidak memengaruhi (P>0,05) bobot relatif organ dalam dan organ imunitas ayam broiler. Pemberian TDG 4,5% meningkatkan (P<0,05) persentase bobot ileum. Pemberian TDG 1,5% meningkatkan (P<0,05) persentase bobot kolon dibandingkan kontrol. Pemberian TDG hingga level 4,5% tidak menyebabkan perubahan fisiologis yang merugikan pada organ dalam, saluran pencernaan, dan organ imunitas ayam broiler.

The prohibition of antibiotic growth promoters (AGP) has encouraged the use of natural phytobiotics, including gedi leaf meal (Abelmoschus manihot L.) which contains bioactive compounds and antioxidants. This study aimed to evaluate the effect of gedi leaf meal (GLM) feeding in the diet on the weight of internal organs, the digestive tract, and immune organs in 35-day-old broiler chickens. A total of 200 Cobb 500 broiler chickens were reared for 35 days in a completely randomized design with 4 treatments and 5 replicates. The treatments consisted of P0 (0% GLM), P1 (1.5% GLM), P2 (3% GLM), and P3 (4.5% GLM) in the diet. Data were analyzed using analysis of variance (ANOVA) followed by Tukey’s test. The results showed that feeding TDG up to 4.5% did not affect (P>0.05) the relative weights of internal organs and immune organs in broiler chickens. Feeding GLM 4.5% increased (P<0.05) the percentage of ileum. The usage of 1.5% TDG increased (P<0.05) the percentage of colon weight compared to the control. GLM usage up to a level of 4.5% did not cause adverse physiological changes in the internal organs, digestive tract, or immune organs of broiler chickens.
