Utilidad de probióticos en la producción de terneras lecheras.

Abstract

The aim of this study is to evaluate the usefulness of probiotics addition in dairy calf diet. Literature was reviewed in different scientific databases such as repositories of Escuela Superior Politécnica de Chimborazo (ESPOCH), Universidad de Cuenca (UCUENCA), Universidad Central del Ecuador (UCE), Universidad Técnica de Cotopaxi (UTC), Universidad de las Fuerzas Armadas (ESPE), undergraduate and graduate thesis, and scientific journals. The type of study was comparative, and results were graphed using Excel. The productive variables reviewed were the following: weight gain (kg) and feed consumption (kg/day), in addition, hematological biochemical parameters and pharmacological action were analyzed. The most relevant results of the investigation indicated that the productive behavior and the biochemical parameters in dairy calves due to the effect of the addition of probiotics did not present significant differences, except for the supplementation of Saccharomyces cerevisiae and Manano, obtaining a higher weight gain of 10,8 kg compared to the non-supplemented and the feed consumption was 2,08 kg/day compared to 2,33 kg/day when added to the diet. Therefore, it is concluded that the addition of probiotics in the diet not show significant effects on the productive parameters except for the combined use of Saccharomyces cerevisiae and manano oligosacárido. It is recommended to determine the most appropriate timing for the supplementation, mixture, and administration of probiotics.
