Abstract

JURADO-GAMEZ, HENRY; ZAMBRANO-MORA, EDWARD  and  VELASQUEZ, CARLOS CHÁVEZ-. Effect of the in vivo supply of Lactobacillus casei in the feeding of Cavia porcellus. Rev.Bio.Agro [online]. 2020, vol.18, n.2, pp.156-165. ISSN 1692-3561.  https://doi.org/10.18684/bsaa(18)156-165.

The sanitary management of the production systems is carried out with the addition of antibiotics (GPA) in the food. However, these practices have increased resistance problems on the part of pathogenic bacteria. From this, the effect of the supply of L. casei on the productive parameters and gastrointestinal region of this species was evaluated. The research was carried out in the facilities and laboratories of the University of Nariño. Zootechnical parameters, blood count, blood chemistry and coprological analysis were determined. Similarly, histology and immune-histochemistry of the small intestine of the animals was performed. It was found that the bacterial supply showed productive parameters similar to those obtained with the control treatments. The results for blood and urine chemistry showed variations in reference data, however, it should be taken into account that the animals used for the evaluation have a difference in handling, given that the majority of reports are in animals of laboratory and few in production systems. In addition, there was a decrease in the presence of gastrointestinal lesions of animals with a supply of L. casei. The results demonstrated the viability of the supply of L. casei in guinea pigs.
