Abstract

A growing study was conducted to evaluate the effect of supplementing NexPro, a high- protein dried distillers grains plus solubles (DDGS) from the FluidQuip MSC post- fermentation separation process, in a corn- silage based diet and to determine the rumen undegradable protein (RUP) content of NexPro. Three test proteins (NexPro, SoyPass, and soybean meal) and 4 inclusion levels (4.5, 9, 13.5, and 18%) were evaluated against a common control (0% test protein). Th ere were no differences in dry matter intake among treatments. Increasing inclusion of NexPro resulted in improved feed conversion and daily gain. SoyPass and soybean meal supplementation also resulted in improved daily gain and feed conversion. Providing additional protein, and specifically rumen undegradable protein, improves cattle performance when fed corn silage growing diets. Performance of steers fed NexPro and SoyPass were similar, which supports NexPro having a similar RUP content.
