Transition time

OUR latest Signet Pigplan figures (see table) coincide with our financial year end of Nov 30. They show the changeover to a closed breeding herd, while so far maintaining our relatively disease- free status, has not been without pain, writes Jasper Renold.

The number of pigs sold is down from last years record breaking 8604 to 7911. We have also had to contend with compound feed price rises of £12/t for sow rations and £15/t for feeding rations. But, a rise in average annual gross price per kgdw from 90.81p to 96.18p and good performance in the growing and finishing herds, has been enough to keep us in the black.

Average carcase weight has increased by 0.5kg and the average P2 probe has dropped from 11.6mm to 11.3mm increasing the number of pigs getting top bonus.

Pre-weaning mortality has increased from 12.6 to 14.1 not helped by staff changes in the farrowing section. Piglets born to litters from dam line Landrace matings have been noticeably less vigorous, but on the other hand those from the PIC Pietrain Solution line are proving to be very lively. &#42
