Table IV. Wolff-Lehmann Feeding Standards for Farm Animals 1 



It has been pointed out in Chapter VII that we now have more accurate data 

 on the nutrient requirements of various classes of animals than were possessed 

 ly scientists when the Wolff-Lehmann Feeding Standards were drawn up. For 

 students and stockmen who desire to compute rations substantially in accordance 

 with the Wolff-Lehmann system, but taking into consideration the results ot 

 •■recent feeding trials at the Experiment Stations, the authors have drawn up the 

 "Modified Wolff-Lehmann Feeding Standards" given in Appendix Table V. The 

 Wolff-Lehmann Standards, as last presented by Lehmann in Mentzel and Len- 

 gerke's Landwirtschaftliche Kalender for 1906, are here given, however, on account 

 of their historical importance. 



The standards for milch cows are given for the middle of the lactation, period 

 with animals yielding milk of average composition. The standards for growing 

 animals contemplate only a moderate amount of exercise ; if much is taken, add 

 15 per ct. — mostly non-nitrogenous nutrients — to the ration. If no exercise is 

 taken, deduct 15 per ct. from the standard. The standards are for animals ofi 

 normal size. Those of small breeds will require somewhat more nutrients, 

 amounting in some cases to 0.3 of a pound of nitrogenous and 1.5 pounds of non- 

 nitrogenous digestible nutrients daily for. 1,000 pounds of live weight of animals.
