Abstract

The main aims of the research presented here were: (1) to model the effects of important housing and management factors on the hygiene level of pig pens; and (2) to evaluate the efficacy of methods aimed at improving pen hygiene. These project aims were achieved by: (I) modelling the hygiene levels measured; and (2) conducting a number of controlled experiments. Hygiene levels were visually assessed in 160 piggery buildings using a standardised 3-step scale system. Engineering and management characteristics of the piggery buildings were recorded at the time of sampling and these building characteristics were used in the subsequent multi-factorial statistical analysis. The mean faecal contamination of pen floors in all study buildings was 36%. According to the model developed, hygiene levels were affected by the size of the farm (as described by the number of sows), seasons, stocking rate per pen (kg weight/m2) and management of piggery buildings. Summer conditions and continuous flow pig management resulted in reduced hygiene levels in pig pens. Piggery size positively, whereas stocking rate negatively associated with piggery hygiene. The results highlighted potential strategies that can be used to reduce the negative effects of sub-optimal piggery hygiene on pig production, environment, health and welfare of animals as well as piggery staff. The related experiments highlighted the importance of keeping pens dry and potentially using bedding materials to mark resting areas in pens as a means of improving dunging patterns in pig pens.
