In order to determine an optimum ratio of vetch and wheat (Triticum aestivum L.) components in their mixture, there has been carried out a four-year trial (autumn 2005 – spring 2009) aimed at the yield and quality of winter vetch haylage. The sowing rate of winter vetch was 120 kg/ha, while the sowing rate of winter wheat was 0, 15, 20, 25 and 30 kg/ha. An increased proportion of the cereal in its mixture with vetch significantly decreases the stand lodging, have a positive influence on forage yield, but haylage quality is of a poorer quality. Quality characteristics such as crude protein and lignin content, total digestible nutrients, dry matter intake and relative feed value were highest in monoculture common vetch followed by mixture with the lowest rate of wheat. Neutral detergent fiber content was positively affected by intercropping. There were no significant differences among treatments for acid detergent fiber content, digestible dry matter, and net energy for lactation. The most favorable balance between the haylage yield and quality, as well as the highest CP yield (1482 kg/ha), was achieved by the mixture of 120 kg/ha of the vetch seed and 15 kg/ha of wheat.
