Whole crops of barley, wheat and oat are normally easily ensiled, but have low aerobic stability. The reason may be that such kind material remains more coarse, resulting in influx of oxygen into the silage. Therefore, lactic acid fermentation also delays. Due to this reason, or several other factors clostridial fermentation easily may occur as well. The aim of this study was to investigate the effect of additives on quality of whole crop silage. the silage crop consisted of about 65 per cent grain, 30 per cent oat and 5 per cent of pea. Additives used were Superben and niben, each added at an application rate of 5 1/ton FM. Whole crop mixture was chopped, mixed with additive and ensiled in 3 litres glass jars. A total of 3 treatments were ensiled with 3 replicates. The results indicated that the quality of silage without using additive was very poor. Extrmly large quantity of butyric acid, ammonia and butanediole were found inuntreated silage. Superben reduced clostridial fermentation but silage quality still remained unsatisfactory. A good quality of silage was obtained with using Niben. It is concluded that the use of effective additive is indispensable for whole cut crop
