Land O'Lakes Purina Feed is calling for registrations for the third annual AMPLI-Calf® Tanbark Challenge®. Participants in this year's Tanbark Challenge® will have the opportunity to win a personalized AMPLI-Calf® jacket and a $50 cash prize. Any spring calf fed an AMPLI-Calf® starter for the first 12-weeks of life, and later exhibited at the All-American Dairy Show, World Dairy Expo or the North American International Livestock Exposition (NAILE) is eligible for this program. Awards will be presented to the highest-placing, qualified calf within the top 10 in each of the seven recognized dairy breeds at each of the three national shows. A calf may only win at one show and must be registered to win. Registration and further information is available online at Entry deadlines for each show are as follows: All-American Dairy Show: August 30 World Dairy Expo: September 13 North American International Livestock Exposition: October 17 In the first two years of the program, Land O'Lakes Purina Feed has awarded prizes to nearly 30 producers – including 2010 winner Jodi Coppini of Tillamook, Ore. "We started feeding calf starter with AMPLI-Calf® to a few heifers. When we noticed how well those calves were doing, we decided to switch all of our calves over," Coppini commented after two of her Brown Swiss heifers won the Tanbark Challenge® at World Dairy Expo in 2010. "This starter is like no other grain; the calves consistently gained more weight, even after being weaned. We have noticed a sizable difference in the height and length of our calves since switching." AMPLI-Calf® calf starter is available with 20 or 22 percent protein from Land O'Lakes Purina Feed dealers. Breeders can ask their local Land O'Lakes Purina Feed Calf and Heifer Specialist, or log on to to learn more about incorporating AMPLI-Calf® starter into their feeding program and to get their calves entered in the 2011 AMPLI-Calf® Tanbark Challenge®.
