摘要：
The oil-bearing rose is one of the main essential oil crops grown in Bulgaria. During the processing of rose flowers rose oil, rose concrete, rose absolute, and rose water are obtained. Waste rose flowers after the distillation of the essential oil still have a limited usage. The objective of the present study is to determine the chemical composition, in vitro gas production, digestibility and relative feed value of waste flowers of Rosa damascena Mill. and their suitability for use as forage. The rose flowers were collected from six fields located in the Kazanlak valley, Southern Bulgaria: three of them are with organic rose production and three are conventional. After their distillation the chemical composition of rose wastes was determined: crude protein, crude fat, crude fibre, ash and nitrogen-free extracts (NFE). Comparative analysis of the chemical composition, structural fibre components: neutral detergent fibre (NDF) and acid detergent fibre (ADF), in vitro gas production and relative feed value (RFV) of rose wastes was made under the conditions of the two production systems.
