Zusammenfassung:The effects of fresh, ensiled and dried alfalfa on performance, carcass and organoleptic characteristics of lamb were investigated in this study. For this purpose, a total of 40 Akkaraman lambs at the age of 4 months and averaging 21 kg of body weight were used. All diets were prepared as isonitrogenous and isoenergetic. The alfalfa form using in rations were composed the experimental group. The experimental groups were fed with wheat straw as roughage was Control group (K-Group) or fed with fresh alfalfa as roughage was YT group, ensiled alfalfa was YS group and dried alfalfa was YK group. The highest dry matter intake (P< 0.001) and daily weight gain (P< 0.01) were found in lambs fed with dried alfalfa (YK group). Feed efficiency ratios in K, YT, YS and YK groups were 5.85, 7.78, 6.21 and 5.91, respectively (P< 0.01). The highest hot (P< 0.001) and cold (P< 0.05) carcass yields were detected in YK group. Smelling parameter was the unique parameter that was determined to be statistically important among all groups (P< 0.05), and the other parameters of sensorial analysis were not found statistically important (P> 0.05). In conclusion, consumption of dried alfalfa as roughage instead of straw in lambs were improved the dry matter intake, daily weight gain and carcass characteristics. Bu çalışmada, taze, silaj ve kuru yoncanın kuzularda performans, karkas ve duyusal özellikler üzerine etkisi araştırılmıştır. Bu amaçla, çalışmada yaklaşık 21 kg canlı ağırlıkta, 4 aylık yaşta 40 adet Akkaraman erkek kuzu kullanılmıştır. Araştırma rasyonları izonitrojenik ve izokalorik olarak hazırlanmıştır. Rasyonlarda kullanılan yonca formu deneme gruplarını oluşturmuştur. Buna göre, rasyonda kaba yem olarak buğday samanı kullanılan grup Kontrol Grubunu (K-Grubu), taze yonca kullanılan grup YT-Grubunu, yonca silajı kullanılan grup YS-Grubunu ve kuru yonca kullanılan grup ise YK-Grubunu oluşturmuştur. Denemede en yüksek kuru madde tüketimi (P< 0.001) ve günlük canlı ağırlık artışı (P< 0.01) YK grubunda tespit edilmiştir. Yemden yararlanma oranları K, YT, YS ve YK gruplarında sırası ile 5.85, 7.78, 6.21 ve 5.91 olarak belirlenmiştir (P< 0.01). Sıcak (P< 0.001) ve soğuk (P< 0.05) karkas randımanı en yüksek YK grubunda tespit edilmiştir. Duyusal analiz değerlendirmesinde sadece koku parametresi bakımından gruplar arasında istatistiksel bir fark tespit edilirken (P< 0.05), diğer parametreler bakımından bir fark bulunamamıştır (P> 0.05). Sonuç olarak; performans verileri değerlend
