Abstract
The aim of the present study was to standardize the monitoring of cough index (CI) in a pre-fattening swine raising. Seven batches of crossbred pigs of 40 animals each, weaned at 26 days of age were kept in cubicles on grooved plastic flooring in a closed facility with mechanical ventilation by means of exhaust fans. Feeding was based on flour concentrate and drinking water supplied by means of nipples. Coughing was recorded in replicates for five and ten minutes at different times (morning and afternoon) by two scorers. The audible coughs per batch of pigs at a given time were expressed as the average number of coughs per pig per minute. Once the method was established, two batches of pigs were monitored kinetically by measuring CI indicator for 10 minutes. Differences between measurement times, morning and afternoon, and scorers with respect to CI, as the dependent variable, were not statistically significant for p < 0.05 by Mann Whitney's U test. CI showed lower interquartile range in measurements during 10 minutes regardless of the evaluator, while higher values were obtained in the morning. CI kinetics revealed a range between 0.018 and 0.03 coughs/pig*minute. It was concluded that CI has the potential to identify moments in the rearing process that may require interventions to reverse or control the worsening of respiratory problems, as well as to measure the effect of actions to control them.
