Effect of non-requested consultation in poor-doing feeder pig finishing herds on daily gain and partial carcass condemnation: An intervention trial



Effect of non-requested consultation in poor-doing feeder pig finishing herds on daily gain and partial carcass condemnation: An intervention trial



Preventive Veterinary Medicine 20(1-2): 1-10



The effect of actively offered, non-requested consultation on average daily gain (ADG), partial carcass condemnation (PCC), mortality and meat inspection findings in poor-doing piggeries was examined. Matching pairs were created from the pool of poor-doing (ADG ltoreq 820 g, PCC gtoreq 3.8%) all-in all-out feeder pig finishing herds. Test herds were randomly selected from matching pairs. The remaining herd of each pair was used as a paired control. Thirty-five herds were visited. Environmental and management factors were monitored. Recommendations for corrections were given. The farmer decided whether or not to follow the recommendations. Thirty-two pairs were used in the comparative analysis. The average number of pigs slaughtered in test and control batches was 362 and 367, respectively. ADG of control batches (799 g) was 10 g better than that (789 g) of test batches but the difference was not significant (P gt 0.1). ADG of test and control batches did not differ (P gt 0.1) in multivariable models controlling for possible confounding factors. PCC percentage decreased by 0.8 percentage unit (P lt 0.05) in the test group and by 0.3 percentage unit (P gt 0.1) in the control group compared with the previous batches. The PCC percentage of test batches was 0.3 percentage unit lower than that of control batches but the difference was not significant (P gt 0.1). PCC percentage of test and control batches did not differ significantly (P gt 0.1) in multivariable models. There were no significant differences between the test and the control batches in mortality, condemnations (whole carcass, liver, other organ) or pathological findings (abscesses, joint infections, pleuritis, pneumonia). The only significant difference found between test and control herds was the average slaughter weight which was 1.6 kg lower (P lt 0.01) in the test group. There were no added benefits in pushing the problem herd producers to consultation. Trying to persuade non-motivated producers to institute corrections was concluded to be unrewarding.
