according to Hayward's own formula. In England, calf meals are fed 

 by nearly every farmer, and Hayward took as a basis for his formula 

 the following mixture, recommended by the agricultural colleges of 



England : 



« 



Flour i6f pounds 



Flaxseed-meal 33I " 



Linseed oil-cake meal 50 " 



With this formula as a basis, a fairly satisfactory meal of the following 

 composition was made Oct. 15, 1901: 



Wheat flour .- 30 pounds 



Cocoanut-meal 25 " 



Nutrium 20 " 



Linseed-meal 10 " 



Dried blood 2 " 



It was supposed that the wheat flour would serve to regulate the bowels, 

 besides furnishing considerable nourishment. Only high-grade flour 

 was used, but it was thought that a low grade of commercial flour might 

 serve as well. 



Cocoanut-meal is a by-product in the manufacture of cocoanut-oil. 

 It was analyzed at the Pennsylvania Station and found to contain 20% 

 protein and 9.03% fat. As cocoanut-oil is of a complex nature, the meal 

 is likely to become rancid in a short time. The meal also has a strong 

 odor of cocoanut-oil. For these reasons it might not be relished. It 

 proved fairly satisfactory, however, in this trial. 



Nutrium is a soluble skimmed milk powder manufactured by the 

 National Nutrient Company at Jersey City, N. J. It is manufactured 

 by drying skimmed milk at a comparatively low temperature and by 

 a certain method of agitation. Nutrium has the appearance of wheat 

 flour and, because it is dry, will keep indefinitely in a dry place. Its 

 composition as determined by the Pennsylvania Station was: 



Water 8 . 60% 



Ash 6.62% 



Protein 33-93% 



Lactose 50 . 50% 



Being virtually skimmed milk dissolved in water, it was thought that 

 a great part of the. success in the feeding of the calf meal was due to the 

 nutriiim used. The chief objection to the nutrium was its cost.
