5. Salix Extract: Impact on the Quantity of Escherichia coli in the intestines of Broiler Chickens Exposed to the Heat Stress

Escherichia coli (E. coli) is a normal flora and a facultative anaerobic bacterium that plays an important role in the nutritional humoral metabolism of broiler intestines. This study aims to determine the effect of jaloh (Salix tetrasperma roxb) extract 50 and 100 mg/liter in drinking water of E. coli colonies in the broiler intestines that experiencing heat stress. The sample is 12 intestines of broiler strain MB-90 aged 28 days. The method used a completely randomized design. The study by user 3 treatments: P0 was not given jaloh extract in drinking water; P1 and P2 were given jaloh extract 50 and 100 mg/liter in drinking water. The data were analyzed using One-way Anova and were continued with the Duncan test. We can conclude that the jaloh extract given to broiler chickens that had heat stress could affect a large number of E. coli colonies. This can be seen from the doses given, indicating that the number of E. coli colonies in chicken intestines experiencing heat stress depends on the dose of jaloh extract given. The higher dose is given, the fewer colonies in the chicken intestine
