- Effect of stocking rate and floor types on performance, skin temperature and leucogram in pigs raising Diovani Paiano Ivan Moreira Arley R.B. Quadros Natalia Cristina Milani Maria Luisa A. Nunes Z Gustavo Machado Aleksandro S. Da Silva Veterinaria feed gain ratio Bioclimatology thermoregulation Objective.The aim of this study was to evaluate the performance, thermoregulatory characteristics and the leukogram of growing finishing pigs reared in different stocking rates kept on compact floor pens or with shallow pool pens. Materials and methods. Thirty-six pigs were used in two steps (total of 72 animals were used). In the first step it was analysed performance pig (daily feed intake, weight gain and feed: gain ratio) and backfat thickness (P2). In the second step, the same analyzes were repeated, in addition, analysis of leukogram and skin temperature was performed in P2 and anal region, at the end of growing and finishing phase. Results. It was evaluated for differences between treatments and stocking. It was not found effect of floor type on growing phase, but the use of shallow pool had a negative effect on the gain and feed: gain ratio in the finishing phase, as well as lower surface temperature in the anal region on treatment with shallow pool in the finishing phase. No effect of treatments and type of floor on pig leukogram. Allowing more space/animal decreased backfat thickness. The use of shallow pool affected negatively the performance in the finishing phase. Conclusions. The shallow pool uses impair the finishing pig performance, despite improving thermolysis, with no effect observed on cell immune response. 2017 artículo científico 0122-0268 https://www.redalyc.org/articulo.oa?id=69353271002 https://www.redalyc.org/journal/693/69353271002/ https://www.redalyc.org/journal/693/69353271002/html/ https://www.redalyc.org/journal/693/69353271002/69353271002.epub https://www.redalyc.org/journal/693/69353271002/movil en http://www.redalyc.org/revista.oa?id=693 Revista MVZ Córdoba application/pdf Universidad de Córdoba Revista MVZ Córdoba (Colombia) Num.1 Vol.22
