FUNDAMENTALS OF AGRICULTURE. 



ents required per day for farm animals under all con- 

 ditions of work and rest. This table is based on 

 1,000 Ibs. live weight. Table B is similar to Table A, 

 except that the standards are based on the weights of 

 the animals as mentioned. To make this clearer the 

 first standard in Table A is for " oxen at rest in stall." 

 The standard reads 17.5 Ibs. dry matter, 0.7 Ibs. pro- 

 tein, 8.3 Ibs. carbohydrates and fat, 9.0 Ibs. total, with 

 a nutritive ratio of i :i 1.9. This standard is for oxen 

 weighing 1,000 Ibs. at rest in the stall. The first 

 standard in Table B is for " growing cattle 2-3 months 

 old weighing 150 Ibs." The standard reads 3.3 Ibs. 

 dry matter, 0.6 Ibs. protein, 2.8 Ibs. carbohydrates and 

 fat, 3.4 Ibs. total, with a nutritive ratio of i '.4.6. This 

 standard is figured on growing cattle weighing 150 

 Ibs. 



Practical Use of Feeding Standards. It must be 

 remembered that the dry matter is given in this table 

 to regulate the bulk of a ration. In compounding 

 rations it is not necessary to have the dry matter ex- 

 act, and a variation of a few pounds does not affect 

 the value of a ration. In feeding farm animals no 

 other food should be allowed them except what is in- 

 cluded in the ration. Animals will eat a great deal
