Effect of feed containing fermented catfish waste by Lactobacillus paracasei, Bacillus subtilis, Saccharomyces cerevisiae on microflora intestine in super native chicken

This study aimed to determine the effect of fermented catfish waste (FCW) Lactobacillus paracasei, Bacillus subtilis, and Saccharomyces cerevisiae (LBS) microbes in diets on microflora intestine on nativ super chicken. The study used 24 nativ super chickens aged 14 weeks, which were reared for 14 days. The method used was a completely randomized design with six treatments (R0 = Lower control diets without the use of FCW (15% CP and 2750 kcal/kg ME); R1 = Diets containing 5% FCW (15% CP and 2750 kcal/kg ME); R2 = Diets Containing 10% FCW (15% CP and 2750 kcal/kg ME); R3 = Diets containing 15% FCW (15% CP and 2750 kcal/kg ME); R4 = Diets containing 20% FCW (15% CP and 2750 kcal/kg ME); dan RS = Upper control diets without the use of FCW (CP 18% CP and 2750 kcal/kg ME)) and four replicates. The results showed that the use of FCW by LBS microbes did not have a significant effect (P>0,05) on total intestine microbe and total Escherichia coli and had a considerable impact (P<0.05) on Staphylococcus aureus. Using as much as 5% in the diet formula gave the best Escherichia coli and Staphylococcus aureus value with the lowest value microflora intestine for nativ super chicken.
