Energy balance and energy utilization of cows during and after feeding protein in excess 3. the influence of incorrect protein nutrition of lactating cows and its residual effects



Energy balance and energy utilization of cows during and after feeding protein in excess 3. the influence of incorrect protein nutrition of lactating cows and its residual effects



Zeitschrift fuer Tierphysiologie Tierernaehrung und Futtermittelkunde 54(1): 41-54



In a respiratory trial with 18 lactating cows direct and residual effects of varied protein supply on energy metabolism and performance were examined. Increasing N intake caused a higher intake of non-restricted water. There was a relation between N supply and excretion of water with feces, urine, milk, skin and lungs, while water deposition did not change. When feeding protein in excess, the lower fecal and the higher urinary energy excretion nearly compensated, so there was only a little more metabolizable energy available for those animals fed protein in excess than for the control group. With protein depletion metabolizability of energy was decreased by .apprx. 4% units. No residual effects of incorrect protein nutrition on those criteria were noticed. Heat production was higher with increasing crude protein content of the ration showing a strong relationship to the intake of metabolizable energy. Obviously there were residual effects of the varied N supply on heat production in subsequent periods. Animals fed too much or too little protein excreted less milk energy than animals of the control group. After appropriate N supply the previously decreased milk energy did not completely approximate to the level of the control group. The efficiency of utilization of metabolizable energy for lactation was scarcely affected by the protein content of the rations.
