Peso de órgãos e histomorfometria intestinal de suínos F1 (Duroc x Hampshire) e Moura.

Abstract

The objective was to evaluate the relative weight of the liver, pâncreas, empty and full stomach, empty and full intestines and their lenghts, relative weight of the spleen, lung, heart and kidneys and the intestinal histomorphometry of F1 pigs (Duroc x Hampshire) in relation to animals of the Moura breed. For this, 1 animals were used, six from each genetic group with na avarage Initial weight of 20 ± 2.6 kg and approximately 70 days of age. The animals were distributed in a randomized block design and divided into two treatments: Treatment 1- F1 animals (Duroc x Hampshire) and Treatment 2- Moura animals. The animals were housed individually in cubicles with a compact floor, equipped with pacifier-type drinkers and masonry feeders. At 180 days of age the animals were slaughtered. It was found that there was na effect (P<0.05) of the different genetic groups in which F1 pigs (Duroc x Hampshire) had lower spleen relative weight, greater intestinal villus height, better villus height/crypt depht ratio and greater absortive área in the Duodenum in relation to Moura. It is concluded with the results verified that the F1 pigs presented better health of the intestinal epithelium and greater área of contact with the food, therefore, they have greater absortive capacity of nutrients which can reflect positively in the zootechnical indexes.
