Abstract

An experiment evaluated the effects of finishing diets containing dried distillers grains supplemented with degradable intake protein on performance and carcass characteristics of yearling heifers. Diets contained 10% or 20% dried distillers grains (DDG) with or without 0.80 or 0.63% urea. Degradable intake protein balances were -192 (10% DDG no urea), 58 (10% DDG + urea), -111 (20% DDG), and 81 (20% DDG + urea) grams/day. No response in performance or carcass characteristics were observed among treatments. The results indicate sufficient amounts of urea were recycled to the rumen to meet the degradable intake protein requirement. Therefore, supplemental degradable intake protein is not necessary in finishing diets containing dried distillers grains at 10% or 20% of diet DM.
