Effect of floor type on the growth performance and health status of growing-finishing pigs
AbstractUsing a factorial design: two full floor types, concrete vs. concrete waterproofed with resin (resin floor) and two slat types, concrete vs. metal, were used to house 72 pigs in four rooms (18 pigs/room). During the experimental period which lasted from 22.9 kg to 112.7 kg live weight the four groups of pigs received the same feed. Growth, water consumption and health status of the pigs as well as subjective odour level inside the rooms were studied. The resin floor with metal slats tended (P<0.1) to improve feed conversion efficiency and positively affected (P<0.03) pig health. In the room with the resin floor and metal slats odour level was significantly lower than in the other three rooms. The potential predictive function for the relationship between average daily water consumption (WC, in L) and feed average daily intake (FADI, in kg) is WC = 2.692 x FADI sup(1.265). Odour level increased with pig live weight. The use of resin as an impermeable floor material is promising for housing growing, finishing pigs.
