Identificación de microorganismos procedentes de alimento balanceado peletizado para cerdos en la etapa de crecimiento y engorde con pruebas bioquimicas api 50 chb

Abstract

The aim of this research work was to identify microorganisms from pelleted balanced feed for pigs in the growth and fattening stage with API 50 CHB biochemical tests. For the identification, biochemical tests API 50 CHB were used in the Laboratory of Biological Sciences and Bromatology of the Faculty of Livestock Sciences of the Escuela Superior Politécnica de Chimborazo. Four samples (1 kilogram) of elaborated balanced feed were used, for the analysis the mixtures were prepared with distilled water and nutrient agar for sowing in Petri boxes at a temperature of 27 ºC for 48 hours for the identification of existing microorganisms, the duration of the research was 60 days (sample taking, culture preparation, API test preparation, microscopic evaluation), The duration of the research was 60 days (sampling, preparation of cultures, preparation of API test, microscopic evaluation), due to the fact that the production process today of balanced feed is of great importance in the agricultural sector and shows interest in terms of the duration of life perch of balanced feed, being a mixture of ingredients designed to provide balanced nutrition in the diet of pigs becomes a problem when there is no adequate knowledge at the time of rationing the amounts of the ingredients causing the deterioration of the same with speed. The results were measured by means of a descriptive statistical analysis with measures of central tendency (mean), the biochemical tests API 50 CHB in the samples of the balanced feed present (BAL) bacteria of the Lactobacillus genus with rhizoid and round shapes; flat, round and convex elevation; lobulated and whole margin; yellow and cream color; rough, shiny and creamy appearance; opaque density; viscous consistency. It was concluded that balanced feeds, help in animal health with the prevention of infectious diseases. It is recommended to reduce the use of antibiotic growth promoters to avoid future problems.
