Abstract

This study was carried out to determine the effect of object combination as environmental enrichment on behaviour of growing pigs. Thirty-six (36)  crossbreed (Large White X Landrace) growing pigs with average weight of 34-36Kg were allotted randomly into four treatments, replicated three times in a completely randomized design. The four treatments were; Control (without enrichment), PRope (2 pieces of polyester rope), treatment  SWood (2 pieces of soft wood) and treatment PRope+SWood (1 piece of soft wood and 1 piece of polyester rope). Behavioural observations were monitored by CCTV and recordings were made for 6 hours/day and 3days/week. At the end of the experiment, data collected includes average feed intake and average weight gain while feed conversion ratio was calculated. Likewise, behavioural observations; enrichment use, general activities, pen manipulation and pen-mate manipulation were observed. Behavioural data were analyzed using repeated measures analysis of variance (ANOVA) while performance data were analysed using oneway ANOVA. Performance data were significantly influenced (P<0.05) by enrichments for all the parameters measured. PRope+SWood had the highest value for the final weight (50.63kg), average weight gain (15.95kg) and average feed intake (56.61kg) while PRope had the highest FCR 4.18). Penmate manipulation (10.48%), pen manipulation (19.02%) and general activities (14.62%) were lower and significantly better for PRope+SWood compared to PRope and SWood and the highest interaction with enrichment objects was observed in the PRope+SWood (55.88%). It can be concluded that the use of combination of enrichment objects enhanced the performance and  behaviour of pigs.
