A farm represents a single production site.

I OWA S TATE U NIVERSITY Department of Animal Science Company / farm summary  Increase in the number of companies and farms represented  Tremendous increase in the data volume evaluated  Results in improved information and interpretations that can be made  Companies becoming much more data driven in their decision making process

I OWA S TATE U NIVERSITY Department of Animal Science Company / farm summary  Grow-finish and wean-to-finish becoming farms becoming more like their sow farm counterparts  Farm level decisions much more data driven  Continue greater use of data when guiding company decision process regarding:  Employee  Financial  Health  Nutritional  Genetic  Some combination

I OWA S TATE U NIVERSITY Department of Animal Science Benchmarking - Why do it?  Compare with other businesses  Within species  Across species  Compare herd performance  Within company  Within country  Etc.  Set goals for improving herd  For a specific trait or several traits

I OWA S TATE U NIVERSITY Department of Animal Science Overall data summary  Finishing mortality has declined over time  Across all data conventional finishing mortality was similar in 2012 and 2013  Wean –to- finish mortality increased slightly in the same time period - initial effects of PED??  Market weight continues to increase  Increased by 4 pounds in both conventional finishing lbs. (2012) and (2013) and wean – to - finish summaries lbs. (2012) to lbs. (2013).  Days in the finisher has remained relatively constant over last 3 to 4 years

I OWA S TATE U NIVERSITY Department of Animal Science Overall data summary cont’  Nursery performance has change little across the reporting time period  Pigs/mated sow/ year has increased by almost 2 pigs from 2008 to  Pigs/mated sow/ year was essentially the same between 2012 and  No improvement since 2011  Why ?? First signs of PED??  Again, litters/mated sow/year has changed little during the time period

I OWA S TATE U NIVERSITY Department of Animal Science Overall data summary cont’  Percent pre-weaning mortality has increased.  Increased in 2013 to 17.3% from 15.5% in 2012  Early signs of PED??  Represents lost opportunity  Easy to improve??  Weaning age has increased by 2 days from 2008 to  19.7 days in 2008 to 21.9 days in 2013  Weaning weight has increased by 2 lb.

I OWA S TATE U NIVERSITY Department of Animal Science Table descriptions  Tables 6-9 and have the average and standard deviation for each key productivity indicator by top 10% and bottom 25% of farms in each production stage, respectively.  Farms in each percentile were determined for each KPI  Farms in each percentile were not the same for each production indicator  The top and bottom were defined as desirable or undesirable for each trait (rather than higher or lower)

I OWA S TATE U NIVERSITY Department of Animal Science Top 10%

I OWA S TATE U NIVERSITY Department of Animal Science Top 10% summary  Separate out to understand performance levels attained by the very best operations for each KPI.  Demonstrates at least what potential is  Top 10% farms pigs/mated sow/ year was 28.5  Where are the 30 PSY herds  Demonstrates how difficult it is to achieve and sustain the outstanding performance for any of the KPIs  Recognize that top performance can contribute to reduced trait variation

I OWA S TATE U NIVERSITY Department of Animal Science Top 10% summary  Performance is what sets producers / operations apart  Reduced variation can also be important  Caution – by definition variation (standard deviation) should be smaller when the overall group is divided into subgroups. – variation or standard deviation more comparable when comparing two subclasses with each other.

I OWA S TATE U NIVERSITY Department of Animal Science Top 10% summary  Represents above average performance for each KPI.  Does not describe the relationship with other KPIs and ability to maintain all at top 10%.  Can use this to establish goals for certain KPIs  Be sure that when setting goals they are attainable and are achievable in a reasonable time frame.  Realistic if you are in the bottom 25% to expect top 10% performance within 6 months of establish new goals  Goals that are set too high are not seen as incentives by barn workers
