The study looked at how different supplements affect the breakdown of straw in cattle. They tested three types of supplements: concentrate mixture, green Lucerne, and urea-molasses block lick. The results showed that the supplements increased the intake of dry matter in the cattle. The concentrate mixture was the most effective at improving the breakdown of straw, while the green Lucerne had a smaller impact. The urea-molasses block lick was only effective on untreated straw. Overall, the supplements had a significant impact on the breakdown of straw in the cattle, with the concentrate mixture being the most beneficial.
