AGP ban causes minor problems in pigs

The ban on AGP's which came into effect January 1st did not have significant effects on the technical results for fattening pigs and sows. This is the conclusion of feed producer Agrifirm that compared the results of 60 sow farms and 134,000 fattening pigs.

Agrifirm compared the technical results from January till June 2005 (before the ban) with the same period this year.

Health costs are higher
The adjustments made in the sow and piglet feed showed minor changes in technical results, according to manager pigs Ben van Raaij. Only the pig loss was slightly higher than last year (Table 1). "This may be due to the fact that we noticed an increase in piglets born alive with 0.2. It is unsure why the health costs are higher compared to last year. "More medicines may have been used", said van Raaij.

Slight decline in growth
Also the results from 134,000 fattening pigs (from 215 groups) have been analysed in the period May till August 2005 and compared with the same period this year (Table 2). Van Raaij concludes a slight decline in growth. The feed conversion rate has been dropped with 1%. Van Raaij expected a drop in 3-4% after the AGP ban.
