In succession to their previous report, the authors have carried out some further experiments on various conditions for making good grass silage, of which the results may be summarized as follows : 1. The wilting of the grass as well as the addition of preservatives turned out to be desirable also for making good quality timothy silage. The addition of about 5-10% beet pulp gave always better results than non-addition and good effects on the formation of acids in the silage. The carotene content of this grass silage reached about half or more of the original amount. The retention of protein in the timothy silage was far more satisfactory than in the hay 2. In redclover-timothy silage, the mixing proportion of their components have considerable effects on its quality. The proportion of 25% of redclover and 75% of timothy gave generally the best results, the increase of redclover causing always the formation in excess of acetic and butyric acids. 3. The pressure applied on the silage has also no little effect. on the quality of grass silage, greater pressure giving generally better results. 4. Good quality redclover, silage was known to be prepared by wilting before ensiling for about 2-3 hours and by the addition of about 2% beet pulp. 5. In the case of wild grass silage, the addition of preservatives such as beet pulp, corn meal, rice bran, or wheat bran, to about 5-10% of the whole amount, proved to be highly effective, giving invariably better palatability as compared with non-addition. In this case the carotene retention attained to about 30-40% of the original amount. By pursuing the change of chemical composition, including the analysis of acids formed, it has been known that the quality of silage improves in pace with the lapse of days after ensiling, becoming more or less stabilized in 28-35 days. About one third of the original content of carotene was known to be retained on the 35th day after ensiling. 6. In the redclover silage, the change of chemical composition proceeded more or less similar to that in the wild grass silage, except that the acids formed were somewhat less in amounts than in the latter. As it is considered that various conditions and factors may affect the change of composition of the silage, the authors are continuing more detailed study of these problems.
