Over the years, various swine
production systems have greatly
improved productivity and reduced
the cost of production. But most
have had relatively lesser success in
controlling some of the most serious
swine diseases affecting the
industry today.
Also, those production methods
have failed to recognize and meet
the special needs of the replacement
gilt population.
Those limitations gave birth to a
system called parity-based management
or parity segregation. First
seen in Canada, and later in the
U.S., it centers on separating the
gilt herd from the main sow herd
and growing and finishing pigs.
This 38th edition of the Blueprint
series from National Hog
Farmer explores the birth of this
concept as well as the reproductive
implications, nutritional considerations
and options from health and
housing standpoints.
A final story reviews the
National Pork Producers Council’s
Maternal Line Program, taking a
closer look at longevity and performance
differences between genetic
lines.
