| Popis: | This study aimed to assess the bioeconomic performance of feedlot steers fed diets with high concentrate (80%) containing different levels of grounded grain of millet as a replacement for grounded corn grain. We used 89 European-zebu crossbred bulls, with initial average weight of 317.8±15.1kg and average initial age of two years, randomly assigned to diets with different levels of substitution of corn by millet (0, 33, 66 and 100%).The animals were allocated in 16 collective pens. The experimental design was a completely randomized design with four treatments and four replicates (pens). The nutrient intake, except neutral detergent fiber and non-fiber carbohydrates, did not differ between the diets tested (P>0.05). The average daily weight gain, body weight and final body codition score were not affected (P>0.05) by increasing the level of millet in the diet. The feed conversion increased 0.0048 kg of dry matter/kg of weight gain for each percentage point of millet in the diet. The total cost decreased linearly (P |
