The aim of this study was to evaluate the effects of live yeast culture and the combination of live yeast culture with vitamin-mineral supplementation as a feed additive on fattening performance, some blood and rumen fluid parameters in male kids. Totally 18 male Saanen goat kids were divided in to one control and two treatment groups each containing 6 kids. Rations of groups were formulated as isonitrogenic and isocaloric. Live yeast culture (YC) and the combination product (YVM) (RumiSacc® and Intetotal® respectively,by Integro Food Industry and Trade Co., Istanbul, Turkey; Live yeast cell 344 x 1010 cfu per gram) was included in the concentrates at 0 (C), 1% (YC) and 1% (YVM) on feed basis, respectively. Feeding schedule was established with only concentrate. Feed was given ad libitum and roughage was not given. Dietary yeast culture at the level of 1% increased final live weight (+4.7% regarding control group). All investigated fattening performance with rumen fluid and blood parameters were not statistically affected with the supplements. It is concluded that live yeast culture and its vitamin-mineral combination did not have adverse affect in male kids fed without roughage
