It is practically impossible to get the exact amounts as laid 

 down in the standard. The above ration is perhaps nearer the 

 standard than one will ordinarily approximate. 



Rations for Animals Weighii^ More or Less Than 1,000 Lbs. — 



If animals weigh more or less than 1,000 lbs. it is necessary 

 to increase or decrease the amounts of the feed proportionately. 

 The nutritive ratio, however, should remain the same. In the 

 above example suppose the horse weighs 1,200 lbs., then we would 

 increase the amounts of feed one-fifth. That is, instead of feed- 

 ing 2 lbs. of cotton-seed meal, 6 lbs. of shelled corn, 6 lbs. of 

 wheat bran and 13 lbs. of timothy hay we would feed 2.4 lbs. 

 of cotton-seed m«al, 7.2 lbs. shelled corn, 7.2 lbs. of wheat bran 

 and 15.6 lbs. of timothy hay. If the animal weighed less than 

 1,000 lbs. the ration should be proportionately reduced. Some- 

 times the individuality of the animal must be considered. Dairy* 

 cattle weighing 700 lbs. giving 25 lbs. of milk need more feed 

 than dairy cattle weighing the same but only giving 15 lbs. of 

 milk. 



Terms of Nutritive Ratio. — Narrow, wide and medium are the 

 terms applied to nutritive ratios.
