In this work, I analyzed phase nutrition dairy cattle practiced on a farm. Furthermore, the work focused on quality of bulky feeds from maize silage, grass-clover silage and field bean silage. Feeding method, composition of rations and production parameters were also evaluated, while taking welfare of the animals into account. For data analysis, a nutrition program was used. Indicators of nutritional values and fermentation characteristics, including microbiological testing of silage feeds (maize silage, grass-clover silage, field bean silage), correspond to a very good standard. For maize silage and grass-clover silage, NDV, ADV and NEL values were shown to be slightly below the national average. When evaluating the nutritional level based on the feed ration optimization, we can conclude that the differences in the monitored nutritional values are within the tolerance limits of the recommended values. The level of nutrition corresponds to the production achieved. Fat and starch content of the feed ration are consistent with the recommended values present in literature.
