Evaluasi Penambahan Ekstrak Kulit Kayu Akway (Drimys piperita Hook f.) dalam Ransum terhadap Organ Dalam Ayam Broiler

Abstract

Penelitian ini bertujuan mengevaluasi penambahan ekstrak kulit kayu akway (EA) dalam ransum terhadap organ dalam, saluran pencernaan, dan organ imunitas ayam broiler. Percobaan ini menggunakan 300 ekor ayam dengan Rancangan Acak Lengkap (RAL) terdiri dari 5 perlakuan dan 6 ulangan, masing-masing ulangan berisi 10 ekor broiler. Perlakuan terdiri dari P0 = ransum kontrol, P1 = P0 + virginiamycin 40 mg kg-1 pakan, P2 = P0 + EA 50 mg kg-1 pakan, P3 = P0 + EA 100 mg kg-1 pakan, P4 = P0 + EA 200 mg kg-1 pakan. Peubah yang diamati yaitu bobot organ dalam, bobot serta panjang relatif saluran pencernaan, dan bobot organ imunitas ayam broiler. Hasil penelitian ini menunjukkan bahwa penambahan ekstrak kulit kayu akway dalam ransum tidak memberikan pengaruh yang nyata (P>0,05) terhadap persentase bobot organ dalam, bobot serta panjang relatif saluran pencernaan, dan bobot organ imunitas ayam broiler. Kesimpulan penelitian ini adalah variasi dosis ekstrak kulit kayu akway yang diberikan tidak memberikan efek negatif terhadap organ dalam, saluran pencernaan, dan organ imunitas.

This study aimed to evaluate the effects of dietary supplementation of akway bark extract (EA) on internal organs, digestive tract, and immune organs of broiler chickens. A total of 300 broilers were used in a Completely Randomized Design (CRD) consisting of five treatments and six replicates, with each replicate containing 10 birds. The treatments were as follows: P0 = control diet, P1 = P0 + virginiamycin 40 mg kg-1 feed, P2 = P0 + akway bark extract 50 mg kg-1 feed, P3 = P0 + akway bark extract 100 mg kg-1 feed, and P4 = P0 + akway bark extract 200 mg kg-1 feed. Observed variables included the weight of internal organs, the weight and relative length of the digestive tract, and the weight of immune organs in broilers. The results showed that supplementation of akway bark extract in the diet did not significantly affect (P>0.05) the percentage of internal organ weight, the weight and relative length of the digestive tract, or the weight of immune organs. The conclusion of this study is that the different levels of akway bark extract supplementation did not exert any negative effects on internal organs, the digestive tract, or immune organs of broilers.
