Resumo

The goal of this study was to compare the growth performance of growing/finishing pigs housed in a hoop barn system and in traditional confinement. A total of twenty Bísaro breed pigs, with 98.6±5.71 days of age, and 25.4±4.87 kg of BW were used (beginning of experiment). The pigs were equally distributed in two groups: Gr1 – hoop barn (2.4 m2/pig) with outdoor access (200 m2/pig); and Gr2 - traditional confinement with straw bedding (1.8 m2/pig). Both groups were fed with the same diet. During the next 98 days’ period (growing phase) and until pigs reached approximately 80 kg LW, the animals were fed with a concentrate diet. In the finishing phase consisting of a final 70 days period until slaughter, the animals reached between 110-120 kg LW and were fed with concentrate and cornflour. The feed intake per group was registered daily and growth performances were collected every two weeks. During the growing phase no differences (P > 0.05) were observed in the average daily gain (ADG) between Gr1 (0.546±0.10 kg/day) and Gr2 (0.563±0.05 kg/day). However, a higher variability was observed in hoop barn group (CV of 18.1% vs. 8.8% in confinement). Similar results were observed during the finishing phase with ADG of 0.535±0.09 kg for Gr1 and 0.505±0.07 kg for Gr2 (P > 0.05). In both growing and finishing phases, the feed conversion rates (FCR) were 3.11 on the Gr1 versus 3.12 kg/kg on the Gr2, and 3.44 in Gr1 versus 3.53 in Gr2, respectively. Despite the different housing systems, ADG and FCR per period were identical in both systems. To the consumer's point of view, the positive aspects of the hoop barn system, such as the use of uncultivated land, product image and pig welfare, are sustainably attractive and therefore could be further reflected in the market.
