Seminar #1
Gilt Development and Acclimatization
Rodger Main, chair

This seminar will provide attendees with an applied overview of the fundamentals involved in preparing replacement gilts for maximal productivity. We will begin with an applied review of literature followed by a domestic and international review of alternative systems of gilt development. We will then have our paradigms challenged by a look into how leaders in the poultry industry are acclimatizing replacement females. Finally, we will conclude with a detailed review of both traditional and emerging methods of acclimatizing replacement gilts.

Optimizing Reproductive Efficiency
John Waddell, chair

Top reproductive performance as measured by pigs per sow per year is an elusive goal for some farms. While 30 p/s/y is not yet common in Denmark , there are enough farms achieving and sustaining this level of production to demonstrate that it is possible with today’s genetics and technologies. This seminar will provide practical, take home advice on how we can help our clients push the envelope of reproductive efficiency towards 30 p/s/y.
