The aim of this study was to determine the effects of using rose pulp (Rosa damacena) silage instead of sugar beet pulp silage on fattening performance, carcass yield, and some ruminal fluid parameters in lambs fed with total mixed ration. For this purpose, a total of 16 (average 30 ± 5 kg) 6-month-old Pırlak lambs, 8 in each group, were randomly divided into two groups. Total mixed rations were formulated by using concentrate, wheat straw and rose pulp silage (RPS) (Group 1) or sugar beet pulp silage (SBPS) (Group 2) in the experiment. Due to the low dry matter content of rose pulp, 7% wheat bran was added to its silage (RPS). The physical and chemical properties of both silages were evaluated, and rations were formulated as isocaloric and isonitrogenic. The study lasted 8 weeks after 2 weeks of the animals’ adaptation to the ration. Live weight, live weight gain, feed consumption, feed conversion ratio, hot–cold carcass yield and ruminal parameters such as volatile fatty acids, protozoan number, pH, and ammonia nitrogen concentration were measured in the experiment. It was determined that the acetic acid level (12.4% DM) of RPS was approximately 6 times higher than SBPS, and the butyric acid level (3.83% DM) was 3 times higher. At the end of the study, it was determined that the difference between the performance parameters of both groups was not significant. Apart from acetic and butyric acid, rumen fluid parameters were not affected by the usage of RPS in the ration. It was concluded that the rose pulp silage consisting of wheat bran (7%) can be used as an alternative silage source to feed small ruminants instead of sugar beet pulp silage without any adverse effects.
