| Abstract | Six Holstein steers (118 kg BW) were fed two diets (DW and Control) in a crossover treatment design to examine nitrogen and phosphorus utilization. In the DW diet, sundried duckweed was substituted for a portion of the soybean meal in the control diet to make the two diets isonitrogenous. Since duckweed was high in phosphorus content (1.61% DM basis), the control diet was supplemented with mono-dicalcium phosphate to make both diets isophosphoric. Phosphorus digested (g/d), percentage phosphorus digested, phosphorus retained (g/d) and percentage phosphorus retained were greater (P<0.01) for calves fed the duckweed diet. Results regarding the efficiency of nitrogen utilization from both treatments were inconclusive. |
