Productive performance and histological appearance of the small intestine and cecal appendix of rabbits fed with triticale added xylanasa

Abstract

The objective was to evaluate the addition of xylanase on the productive performance and histological aspects of the small intestine and cecal appendix of rabbits fed diets containing triticale. 120 rabbits were randomly distributed to one of the four treatments differentiating them from the inclusion of xylanase (0, 4000, 8000 y 12000 XU/kg, respectively), the animals were weighed weekly and at the end of the experimental period, the rabbits were slaughtered taking samples of the duodenum, jejunum and cecal appendix to perform the technique of staining with Hematoxylin-Eosin (HE). An analysis of variance was performed using the GLM procedure of SAS (2002) and Tukey’s test. The addition of xylanase enzyme increased (p<0.05) the live weight at day 4 and 7 of the rabbits and increased (p<0.05) the areas of intestinal villi of the duodenum, jejunum and cecal appendix.
