Effect of pig housing system on blood biochemical indicators’ level

Abstract

Wpływ systemu utrzymania trzody chlewnej na poziom wskaźników biochemicznych krwiSummary. The aim of the study was to evaluate the influence of different pig housing systems on the level of chosen biochemical indicators in pig's blood. The level of ACTH along with haptoglobin, lysozyme and IgG were determined in 20 sows and 150 piglets of crossed breeds: Polish Large White × Polish Landrace. The animals were kept in two different housing conditions: two facilities contained straw bedding (sows n = 10, piglets n = 75) in other two slatted floor without straw bedding access (sows n = 10, piglets n = 75). Biochemical indicators in sows and piglets were determined by taking blood samples after weaning (at the piglets' age of ca. 30 days). Statistically significant influence of the housing system on the value of the determined indicators was showed. The level of both ACTH and immunity indicators was statistically significantly higher in animals housed without bedding. In sows the values of all indicators were higher than in piglets. The housing system on straw bedding turned out to be more favourable for pigs. Animals housed on slatted floor were more stressful.
