The lack of dry carry over feed (or fibre) from summer means that lush short green pastures are devoid of fibre. Fibre is extremely important for normal rumen function in ruminants and assists with saliva production, aiding in rumen buffering and mineral absorption. With cereal hay prices reaching highs of $240-$250/t on farm, cereal straw is representing the best value on a cents/MJ ME basis. In fact, cereal straw has been testing as high as 8.5 ME – a result of moisture stressed crops that were cut for hay before starch development occurred. This resulted in high water soluble carbohydrate levels in the resulting straw which has improved palatability and dry matter intake in livestock. Straw is particularly useful for sheep that have been or are currently being fed in containment as it represents the cheapest source of fibre. Straw is also useful to treat grass tetany in cattle, and to transition livestock from full supplementary rations onto fresh green pastures.
