Abstract

In order to evaluate the effect of partial substitution of commercial concentrate in broilers fed with Californian red worm (Eisenia foetida), the present investigation was carried out with a population of (n = 40) Ross line broilers classified according to to sexing. They were cataloged into homogeneous groups of 5 male and 5 female birds homogeneously selected for the experimental and control groups. In the partial substitution, they were divided into: (T1) 10% Californian red worm and 90% commercial concentrate; in the treatment (T2) 20% of earthworm + 80% of commercial concentrate was used; For the group (T3), 30% worm + 70% concentrate was used, unlike the control, it was managed with 100% of the conventional diet. The zootechnical data were statistically evaluated in a completely randomized model in the Excel program where no statistically significant differences were detected (P> 0.05) in the relationship of the variables evaluated with the control, when performing a higher reliability method statistically, the Tukey test to create greater confidence intervals for all the differences between the means of the evaluated groups, determining zero difference between what was evaluated and what was expected, therefore the use of Californian red worm as a partial substitute in the feeding of broilers in the finishing or fattening stage maintains the productive parameters with respect to the conventional diet of commercial concentrate.
