Abstract

The purpose of this study was to find the effect combination probiotic Lactococccus lactis and Lactobacillus casei on the laying hens infected with bacteria Escherichia coli on feed consumption and feed conversion ratio (FCR). The materials used in this experiment were 120 laying hens aged 25 weeks. Feeds were used commercial concentrate produced by PT. New Hope East Java, type 7183A. In this study were added of six treatments that is (a0b0) chicken without infection and without treatment, (a0b1) chicken without infection plus Antibiotic Growth Promoter (AGP), (a0b2) chicken without infection plus probiotic, (a1b0) chicken infection without treatment, (a1b1) chicken infection plus AGP. (a1b2) chicken infection plus probiotic. Each treatment was repeated four times. The variables measured were are feed consumption (g/bird/day) and feed conversion ratio (%). Data were analyzed statistically using Analysis of Variance (ANOVA), if between treatment showed significant effect were analysed by Duncan’s Multiple Range Test (DMRT). The result of this research shows that the use of probiotic Lactococccus lactis and Lactobacillus casei on the laying hens infected with bacteria Escherichia coli give a real distinction ( P0,05) towards feed consumption and showed a real distinction (P 0.05) towards feed conversion ratio. Based on the results of this research, it can be concluded that the addition of probiotic Lactococccus lactis and Lactobacillus casei on the laying hens infected with bacteria Escherichia coli can improve feed consumption, feed conversion ratio (FCR) of laying hens, hen day production (HDP) and egg weight.

Abstract

Escherichia coli is a normal flora in the digestive system of laying hens that are non-pathogenic, which can change into pathogens and cause the egg production to decrease. So the combination of Lactococcus lactis and Lactobacillus acidophilus probiotics is expected to be able to overcome E. coli and become a substitute for the antibiotics (Virginiamycin) in animal feed. This study aims to determine business analysis including Break Event Points (BEP), Revenue Cost Ratio (R / C Ratio), Payback Period (PP) and Return On Investment (ROI). The best results obtained for the calculation of Break Event Point (BEP) on a0b2 treatment with a BEP of Rp. 17,587,24 with BEP production on a1b2 of 14,36 kg, Revenue Cost Ratio (R / C Ratio) generates a value of 1,543 for treatment a0b2, Payback Period (PP) generates a value of 1 year 3 months 9 days and Return On Investment (ROI) generates a value of 3. It was concluded that the a0b2 treatment had good results to be developed.
