Helping to identify problems TARGETS
Always set achievable targets and communicate to the stockpeople. We believe units need to be operating around the following levels:
Conception rates 88-93 %
Farrowing rates 85%
Born alive 11.5 - 12.0 per litter
Farrowing Index 2.4.
Replacement rate 40-45% / year. ANALYSIS
When analysing changes in breeding performance, look at past performance (weekly, monthly, 3 months, 6 months and yearly). Is there a seasonal difference? What else changed at around the time in the fall-off in production?
Records required when diagnosing a problem:
a Parity profile (Target - Gilt Pool 4%, P1 18%, P2 17%,
P3 15%, P4 13%, P5 12%, P6+ 21%.)
a Results by parity. Look at - conception rate, born alive by parity.
Is it a gilt or Parity 2 problem? Look at gilt
Is it a Parity 3 to 5 problem - look at overall serving
Is it a Parity 6 problem - look at culling policy/ replacement rate.
Sow individual ID. Is there a small percentage of very low
productivity sows present?
Gilt weight/age at first service (Target 220 days+, Weight
Weaning to service interval (Target 5 days)
