Efektivitas Pemberian Probiotik Lactococcus lactis dan Bacillus licheniformis dalam Air Minum terhadap Persentase Karkas dan Non Karkas Ayam Broiler

Abstract

Penelitian ini bertujuan untuk mengevaluasi pemberian kombinasi probiotik Lactococcus lactis dan Bacillus licheniformis dalam air minum terhadap persentase karkas dan non karkas ayam broiler. Percobaan menggunakan 400 ekor ayam dengan Rancangan Acak Lengkap (RAL) yang terdiri dari 4 perlakuan dan 5 ulangan. Perlakuan terdiri dari P0 = air minum + 0,005% Dekstrosa (plasebo), P1 = air minum + 0,001% Effective Microorganism-4 (EM-4), P2 = air minum + 0,005% Lactococcus lactis 10^9 dan Bacillus licheniformis 10^9, P3 = air minum + 0,005% Lactococcus lactis 10^9 dan Bacillus licheniformis 10^10. Hasil penelitian menunjukkan bahwa perlakuan tidak memberikan pengaruh yang nyata (P>0,05) terhadap persentase bobot karkas, dada, paha atas, paha bawah, sayap, punggung, kepala, leher, dan kaki. Kesimpulan penelitian ini adalah pemberian kombinasi probiotik Lactococcus lactis 10^9 CFU/g dan Bacillus licheniformis 10^9 CFU/g pada dosis 0,005% serta kombinasi probiotik Lactococcus lactis 10^9 CFU/g dan Bacillus licheniformis 10^10 CFU/g pada dosis 0,005% dalam air minum tidak memengaruhi persentase karkas dan non karkas ayam broiler namun bermanfaat digunakan untuk meningkatkan kesehatan dari ayam broiler.

This study aims to evaluate the administration of a combination of probiotics Lactococcus lactis and Bacillus licheniformis in drinking water on the percentage of carcass and non-carcass of broiler chickens. The study used 400 chickens with a Complete Randomized Design (CRD) consisting of 4 treatments and 5 replicates. The treatment consisted of P0 = drinking water + 0.005% Dextrose (placebo), P1 = drinking water + 0.001% Effective Microorganism-4 (EM-4), P2 = drinking water + 0.005% Lactococcus lactis 10^9 and Bacillus licheniformis 10^9, P3 = drinking water + 0.005% Lactococcus lactis 10^9 and Bacillus licheniformis 10^10. The results of this study showed that the treatment did not give a significant effect (P>0.05) on the weight percentage of carcasses, breast, thighs, drumsticks, wings, back, head, neck, and legs. The conclusion of this study is that the administration of a combination of probiotics Lactococcus lactis 10^9 CFU/g and Bacillus licheniformis 10^9 CFU/g at a dose of 0.005% and a combination of probiotics Lactococcus lactis 10^9 and Bacillus licheniformis 10^10 CFU/g at a dose of 0.005% in drinking water does not affect the percentage of carcass and non-carcass of broiler chickens but is useful to be used to improve the health of broiler chickens.
