Aplikasi Probiotik (Lactobacillus Murinus Hik-3) Pada Ayam Untuk Menekan Populasi Bakteri Coliform dan Salmonella

Abstract

Chicken is susceptible for microbial balance in intestine causing nutrient absorption inefficiency, which might retard its growth. Farmers usually give antibiotic to handle chicken diseases. Long period of application might cause microorganism resistance to the antibiotic. To reduce antibiotic usage, alternatively isolated probiotic resulted from chicken intestinal can be applied. Probiotic is microorganism which consumed in live condition, resistant for bile salt, can colonize to prevent patogen bacteria and benefit for healthy. The objective of study was to investigate the effectiveness of probiotic Lactobacillus murinus Hik-3 to suppress Coliform and Salmonella bacteria population in chicken. The research treated 30 chickens of 14-day old with probiotic Lactobacillus murinus Hik-3. antibiotic, and control for 3 weeks. They were fed-forced with 1 ml probiotic daily. Microbiological analysis included identification of lactic acid bacteria population, total microbial of Salmonella and Coliform bacteria on sample feces. The microbial analysis result of chicken feces showed that the population of lactic acid bacteria tended to decrease, while the population of Colifom, Salmonella, and total aerob microbial tended to be constant during treatment. Population of lactic acid bacteria on Lactobacillus murinus Hik-3 and antibiotic were constant. Further analysis of isolated feces revealed that application of isolated Lactobacillus murinus could not reside in chicken intestinal, and were not able as chicken probiotic agent
