Abstract
The validation of two prebiotic activators in crossbred Ayrshire heifers was conducted in the province of Pichincha, Rumiñahui County, Rumipamba Parish, at 3,000 meters a.s.l. For the field phase, purebred Ayrshire heifers with an average age of 4 to 6 months old were studied and data on their weight, height and waist diameter increase, as well as their body capacity were measured every two weeks. An experimental design (DCA) with covariables, the age being the covariable, consisted of three treatments and five observations for each treatment. The experimental unit was the heifer. According to the analysis of variance conducted for each tested variable, there are no significant differences between treatments; however, for the analysis of the covariable (ANOVA), significant differences were detected for the interaction of each variable.
