This study was conducted to determine the possibility of using carnation by-products as an alternative roughage source for animal feeding in Isparta. For this purpose the carnation by-products obtained from a special firm were evaluated as fresh and silage with no additive compound. Dry matter, crude protein, acid detergent fiber and neutral detergent fiber contents of both fresh and silage carnation by-products were determined. Fleig score, pH and physical quality of silages were also determined. According to the results fresh and silage carnation have 22.64 and 19.76% dry matter, 15.50 and 12.19% crude protein, 42.08 and 39.73% neutral detergent fiber and 29.48 and 28.3% acid detergent fiber contents respectively. Silages fleig scores were 69.59, pH values were 4.37 and physical quality was very good in the study. According to the results carnation by-products both fresh and silages have a good nutritive value for animals and can be used as an alternative roughage source. However, since it is very common practice using pesticides in carnation farming. Using this by-product as animal feed should be taken into account for both animal and human health.
