Among the new features with the re-launch of petfoodindustry.com is a complete archive of the popular Ingredient Issues columns authored by Greg Aldrich, PhD. Located in the Knowledge Center, these articles are indexed by topic and cover everything from amino acids to vitamins. The Ingredient Issues Library includes more than 100 columns covering ingredients such as proteins, grains and starches, fibers and legumes, functional ingredients, and other key categories.

After viewing a number of sample articles, an annual payment of $29.95 is required to view the articles.

The Knowledge Center also gives access to online pet nutrition courses and presentations from past Petfood Forums. All that’s required for access to those areas is registration on the site.

 All of these features have been optimized for easy viewing on computers, tablets or smartphones.
