Probiotics are non-pathogenic microbes with beneficial effects on the health of host and can be used as a substitute of antibiotic growth promoters to increase production efficiency. Microorganisms classified as probiotics must have certain characteristics such as resistance to gastric acid and bile exposure, able to produce antimicrobial substances, and enhance body’s immune system, able to survive in processing and storage.

The use of probiotic combination of Lactococcus lactis, Bifidobacterium sp, Lactobacillus casei has been tested on 18-week-old laying hens. The use of a combination of isolates at 0.5% Lactococcus lactis + 0.5% Lactobacillus casei gives a better effect than the control and use of antibiotic growth promoter (AGP). Improved performance is indicated by a decrease in the value of the feed conversion ratio (FCR).

The use of 0.5% Lactococcus lactis + 0.5% Lactobacillus casei results an FCR at 1.97. The obtained FCR values were better than the control treatments and 0.1% AGP, which resulted in FCR values of 2.19 and 2.15, respectively. Improved performance is also shown by an increase in feed efficiency. The use of 0.5% Lactococcus lactis + 0.5% Lactobacillus casei gives a value of feed efficiency by 51.65%.

The obtained value of feed efficiency is better than the control treatment and 0.1% AGP, which respectively produce feed efficiency values of 48.33% and 49.85%. Based on the results of this study, it can be concluded that the use of a combination 0.5% Lactococcus lactis + 0.5% Lactobacillus casei isolate can be a substitute for antibiotic growth promoter (AGP) to improve growth performance and reduce production costs for feeding.
