October 2005 Blueprint Focus - Weaning Age Revisited


In the 41st edition of the Blueprint series, swine industry authorities list the various pros and cons of different pig-weaning strategies.
First, swine veterinarians Joe Connor, Bill Hollis and Keith Erlandson of the Carthage (IL) Veterinary Service provide an overview of the shift in pig-weaning ages, and its influence on wean-to-finish production and sow performance. How to capture economic payback is also covered. 
In the second article, veterinarian Tom Wetzell of South Central Veterinary Associates of Wells, MN, lists compromises that led to the decline in popularity of segregated early weaning, how increasing weaning age has reduced mortality and its impact on disease organisms. 
A team of Kansas State University experts covers weaned pig nutrition, proper nursery pig management, saving starve-outs, phase feeding and nursery feed budgets, and crucial factors in feeding sows as lactation length increases. 
The final article by Todd See, professor and swine commodity coordinator at North Carolina State University, focuses on the impact of weaning age on sow reproduction.
