Productivity of Arabian chicken given probiotic Lactobacillus sp.isolated from the digestive tract of broiler chickens and laying hens

Abstract

The development of poultry farms has experienced relatively with expensive feed prices. To improve the efficiency of feed usage, can be done through the use of probiotics. The aim of this study was conducted to determine the response of probiotics, containing microbes Lactobacillus sp isolated from the digestive tract of laying hens (Bio-L) and modern broiler (Bio-B). The study used 8 month old of 180 Arabic hens for 6 month period. The study designed using completely randomized design with 3 treatments and 6 replications. Feed given according to farmer formula consisting of factory concentrate 25%, corn 40%, and rice bran 35%, respectively. The treatment given were as follow; P0: chicken without probiotics, P1: chicken with probiotic Bio-L of 1 cc/l drinking water and P2: chicken with probiotic Bio-B of 1 cc/l drinking water, respectively. The results showed that P2 treatment had egg production as 119 egg/head were significantly higher than P1 and P0 tretment. The FCR of chicken on P2 as 2.26, was significantly smaller than on P1 or P0. While the composition and physical quality of eggs did not significantly difference in among all treatments.
