Feedlot parameters of two categories of cull females, cows and heifers, fed two diets, with and without monensin, were studied. The daily amount of monensin supplied was 150 mg/animal. The roughage:concentrate ratio was 65:35. The roughage used was sorghum silage. The inclusion of monensin to the diet caused a significant reduction of the daily voluntary dry matter intake (DDMI), which was more pronounced for the cows (9.1%) than for the heifers (1.7%). The animal category x diet interaction affected significantly […]
