Welcome to the Purdue Dairy Digest!

Purdue Dairy Digest is a podcast series, created by Purdue Extension Animal Scientists, designed to be a resource for industry information. A new podcast will be available every other week for free download by noon on Wednesday. Each podcast will run about two minutes and will include both information directed to dairy farmers and some general information for the public.

Every first and third Wednesday of the month, Purdue Extension Dairy Specialists, Dr. Tamilee Nennich, Dr. Mike Schutz, and others, will speak about topics important to both producers and consumers to help bridge the gap between the two. Podcasts will include information on general dairy topics, management issues, animal welfare, updates on upcoming conferences and meetings and more.

The podcasts are intended to be used and shared by producers and others in agriculture. Each podcast has a 15 second introduction and 5 seconds of silence, followed by approximately 90 seconds of information. Podcasts can also be accessed for free on iTunes by searching “Purdue Dairy Digest”. We hope that you enjoy the Purdue Dairy Digest.
