Urbaniak, M. | Potkanski, A. (Akademia Rolnicza, Poznan (Poland))
An experiment on Polish Merino lambs fed isoenergetic diets containing 10.8, 12.2, 13.6 or 16.9 percent of protein was carried out. No significant changes in rumen N-NH4 content in lambs fed the diet containing up to 13.6 percent of protein was stated. The diet containing 16.9 percent of protein caused a significant increase in N-NH4 level in the rumen of lambs. Nitrogen requirements of rumen microorganisms were covered by rations containing 13.6 percent of crude protein in 1 kg of dry matter of diet
