Summary and Implications
Calcium hydroxide is best used when treating over mature fibrous forage to improve dry matter digestibility and energy availability to the recipient animal. There does not seem to be a strong impact on treating high quality feeds such as good quality corn silage. The treated feed tends to ferment slower, but cattle accept it well and production does not seem to be adversely affected and may, in fact tend to reduce some day to day production variation.
