the effects of propolis and monensin in milk on performance, feed intake and digestibility in holstein suckling calves

in order to surveying the effect of feeding propolis on performance, feed intake and digestibility in holstein suckling calves, the experiment was designed in a completely randomized design with 4 treatments (diet) and 10 replicates (cattle) during 52 days. treatments included: 1. control (without monensin in starter and without propolis in milk); 2. starter without monensin and 500 ppm soluble propolis powder in milk; 3. starter without monensin and 1000 ppm soluble propolis powder in milk; and 4. monensin in starter and without propolis in milk. statistical analysis was done with sas software and proc mixed and glm. there was significant difference between treatments for means body weight during suckling (p
