Abstract

The effect of barley or triticale and monensin on fattening performance of Brown Swiss calves (with average body weight of 170±30 kg) were studied in a completely randomized design with factorial arrangement of 2×2 and 4 replicates. Experimental treatments were: 1- barley grain without monensin 2- barley grain with monensin 3- triticale grain without monensin and 4- triticale grain with monensin. The amount of monensin in the ration was set to be 30 mg/kg DM. Calves weighing was undertaken monthly and dry matter intake was measured daily. Sampling from rumen fluid was carried out using a stomach tube, and blood sampes were taken at the end of each month. Average daily gain, feed conversion ratio and daily feed intake were not significantly affected by the treatments. Monensin had no significant effect on blood glucose concentration. Ruminal N-NH3, blood urea nitrogen and ruminal pH were not significantly affected by the experimental treatments. As grain sources and monensin application had no effect on fattening performance of the calves. it can therefore concluded that triticale grain might be utilized substituted with barley grain in feed lot diets. This substitutionn can be important from the economical of view in calves feed lot interprise.
