WHEY RATION FOR CALF.

our cheese factories, then whey has a greater feeding value 

 than its milk sugar would indicate. The following is the 

 average of his 18 analyses : 



This shows a greater waste than has been supposed of 

 the nitrogenous matter in the whey. The ash also is 

 remarkably large nearly as much as in whole milk 

 but common salt, probably, forms half of this ash, and this 

 comes from the salt used in cheese making. But the 

 albuminous matter forms nearly one per cent., and will be 

 a great assistance in feeding beyond that of nearly pure 

 milk sugar. Yet, to make whey a suitable food to grow 

 the young animal vigorously, we must supplement the oil 

 taken away in the cream the nitrogenous food, the phos- 

 phate of lime, magnesia, sulphur, soda, etc., taken away in 

 the casein, or cheese, and when we have combined these in 

 proper proportion with the whey, we have restored it nearly 

 to its normal condition of milk, and it then forms an appro- 

 priate food to grow calves. This requires a little thought 

 on the part of the feeder ; but every farmer ought to be 

 willing to give thought and care to his business. Probably 

 the best single food to be added to whey is oil-meal. By 

 recurring to the table of analyses given on page 140, it 

 will be seen that oil-meal has 28 per cent, of muscle-form- 

 ing food just what whey is deficient in and also 10 per 

 cent, of oil (another deficiency in whey) ; and it has nearly 

 8 per cent, of ash ; and this ash is made up of phosphate
