Effect of distillery stillage on organ morphometry in pre-fattening pigs

Abstract

To assess the behavior of morphometric indicators of organs in pre-fattening pigs, distillery stillage was used as an additive. For this study, a completely randomized design was used with 20 73-day-old pigs of the Yorkland Duroc breed, divided into two groups of 10 animals each, one of which was used as a control and the other was included in stillage. the diet during the evaluation period (40 days). The stillage used was obtained from the distillery and after carrying out its characterization, it was applied to 1.5 % of the dry matter of the food consumed. Organ morphometric indicators were evaluated. During the study period, the animals did not present pathological affectations in the histology of the organs. An increase in size and weight of the organs was obtained, as well as a longitudinal increase of up to more than 30 microns in the villi and the crypts of the duodenum and ileum of the animals treated with vinasse compared to those not treated with mean values of 340. and 334; 290 and 280 (µm) respectively, which favors the adsorption of nutrients. It is concluded that the use of distillery vinasse as an additive with the dose used for pre-fattening pigs can optimize the use of dietary nutrients and guarantee better health behavior of the piglets.
