Recovery of nutrients during ensilage was investigated with four silages with no additive (control) and four ones added 15% molasses feed (a commercial feedstuff containing 40% molasses) at ensiling. The silos were of concrete cylindrical type with 120cm diameter and 210cm depth. Grass-clover mixture composed mainly of orchardgrass was ensiled for 93 and 177 days for the control group and 108 and 193 days for the molasses feed added group.The results obtained were as follows:1. Silage quality was markedly improved by the addition of the molasses feed. That is, no butyric acid, little ammoniacal nitrogen and much lactic acid were found in the molasses feed added silage, while much butyric acid and ammonia were produced and the amount of lactic acid was small in the control silage.2. Losses of all the constituents during ensilage were much less in the molasses feed treated silage than in the control silage. This seemed to be due to the fact that the fermentation loss and seepage loss were greater in the control silage which contained fairly high moisture.3. Although soluble carbohydrate in the molasses feed was consumed to a large extent during ensilage when added at ensiling, it was generally found that, from the viewpoint of nutrient conservation, the addition of the molasses feed at ensiling was a little more advantageous than the use of silage with no additive plus the molasses feed.
