Efecto del tamaño de partículas de la dieta sobre la digestibilidad de nutrientes en cuyes (Cavia porcellus)

Digestibility measures the percentage of nutrients utilized by the body; the objective of this study was to compare the effect of diet particle size on nutrient digestibility in guinea pigs (Cavia porcellus); we randomly placed thirty 90-day-old female A1 type guinea pigs with an average weight of 1306 g in individual metabolic cages of 51x42x26 cm, we applied a completely randomized design, we formulated the three diets considering the requirements of the NRC (1995) standards with fine, medium and coarse particle sizes, we added vitamin C (0.096 g/kg) post-pellet, we established an adaptation period of seven days, and we collected feces during the following three days, the weight of excreta and of the animals we recorded, established the daily feed consumption, we analyzed the diet and, collected feces using the protocols of the Association of Official Analytical Chemists (2016), We processed The data using the statistical package InfoStat to determine in vivo digestibility coefficients of dry matter, organic matter and crude fat. The results show no significant difference in the digestibility of dry matter and organic matter (p>0.145), obtaining averages of 68.5 and 69.5 correspondingly. We evidenced a trend in crude fat (p>0.096). We concluded that particle size did not significantly affect the digestibility of the nutrients evaluated.
