A ration in which 18% of the nitrogen was supplied as dried activated sewage sludge was found equal, as measured by nitrogen retention, to soybean oil meal and urea-containing rations of similar crude protein content (11–12%). The total nitrogen of the sludge-containing ration had a significantly lower apparent digestibility and a higher biological value. |
