248 SCIENTIFIC FEEDING OF ANIMALS 



material 1-04 kg. protein, 0*32 kg. fat, 6-28 kg. 

 nitrogen-free extract substance, and 3-93 kg. crude 

 fibre, the total starch equivalent being 9-66 kg. 

 On this ration there was a daily gain of 144 g. flesh, 

 325 g. body fat, and 209 g. wool, which is altogether 

 equal to a starch value of i-88 kg. If there had 

 been no gain of wool, flesh, or fat, the animals 

 would have found enough food in 778 kg. starch 

 equivalent per 1000 kg. naked body weight. 



In another experiment with a half-fat English 

 cross-bred sheep which weighed 64-9 kg. with its 

 wool, and without 62-4 kg., the daily ration was 

 550 g. meadow hay, and 440 g. coarsely ground 

 maize. Calculating the ration upon 1000 kg. 

 naked body weight, it would contain o-8i kg. 

 protein, 0-40 kg. fat, 7-05 kg. nitrogen-free extract 

 substance, and 1-37 kg. crude fibre, together with 

 a starch value of 11-24 kg. The production, 

 which was ascertained by means of the respiration 

 apparatus, yielded by this ration was 71 g. each, 

 flesh and wool and 785 g. body fat, which means a 

 starch value of 3-28 kg. If this portion of food which 

 has served for the purposes of production is sub- 

 tracted from the total quantity given, there remains 

 7-96 kg. starch value for the simple maintenance of 

 the animal. 



Mention might perhaps be made here of the 

 relation between the nutrients given and the pro- 

 duction which was observed in the above two
