Elaboración de balanceado peletizado más la adición de probióticos para cerdos en la etapa de crecimiento y engorde.

Abstract

The present research has the main objective of producing a balanced pelleted feeding formula for growing and fattening pigs adding probiotics in the Biological and Bromatological Sciences of the Animal Sciences Faculty at Escuela Superior Politécnica de Chimborazo, the length of the research was 60 days, for the research development related to the proximal and physicochemical analysis 12 kilograms of feeding formula was used, and 64 kilograms for the microbiological analysis. Three levels of additional probiotics were used in this research (2,4 and 6%), to be bought with a control treatment. A completely random design was applied (DCA) with two combinatory arrangement factors; where factor A corresponds to the addiction to the probiotics and the hanger B factor (0,7,14 and 21 days). Reporting results for the proximal analysis, which influenced respectively within the parameters of humidity, protein, ashes, fat and fiber, resulting in no significant differences on the phosphorus and calcium levels. The physicochemical analysis did not influence significatively on the acidity and also the pH which reported significant differences within all the treatments. When determining the hanger life, it was possible to maintain good conditions as the results were maintained under the admitted amounts suggested by the norm in relation to enterobacteria, yeast and fungi. At the same time it was managed to obtain lactic acid bacteria which helped inhibit the growth of pathogenic agents. As a conclusion, any type of probiotics can be used. It is recommended the use of probiotics in other pig production stages, going from the initial phase, gestation and breastfeeding, to test the results with the whole pig farming process.
