FEEDING.

speak, ready for immediate use. And it is the business of the milk dairyman 

 to know what are the best materials for his use, that he may select the most 

 profitable, and when opportunities arise to seize upon them without hesitation. 

 Some years ago the writer was offered a lot of palm nut meal which had been sent 

 here for sale, but no one knowing anything of its value, it was offered at any 

 price that could be procured. Knowing its value for feeding cattle, the writer 

 purchased the lot at once, and it was the cheapest butter-making food he had 

 ever used. In this way a dairyman cannot only choose the cheapest foods, but he 

 may often avoid purchasing other foods at too high prices for profit ; so that 

 an accurate knowledge of the characters of the foods in the market should be 

 made a particular study of every dairyman. 



Reckoning all nitrogenous matter as albuminoids, the following foods have

How to form rations. Suppose we wish to feed meadow hay and rye bran 

 to form a ration having a nutritive ratio of 1 :6. We have a problem like this : 



1:8.0 

 1:6.0 



2.9 



1:6.0 

 1:5.3 



The meadow hay has an excess of twenty parts of carbohydrates and fats 

 to a lack of seven parts of the same elements in the bran. Hence we will 

 take seven pounds of the hay to twenty pounds of the bran : 



1:5.3x20-20:106.0 

 l:8.0x 7 7: 56.0 



27:162.0-=!: 6 



Manifestly we have the proper nutritive ratio, but we must have a greater 

 variety in the food. Suppose we wish to feed orchard grass, wheat bran, rye 

 and turnips in a ration having a nutritive ratio of 1:6. We have this problem: 



1:6.5 

 1:6.0

In the orchard grass and rye together there is an excess of fifteen parts to 

 a lack of six parts in the wheat bran and turnips. Hence take six parts of 

 grass and six parts of rye to fifteen parts of bran and fifteen parts of turnips : 



1:6 5x 6 6:39.0 

 1:7. Ox 6- 6:42.0 

 1:5.6x1515:84.0 

 1:5.8x15=15:87.8

But suppose we wish to feed one pound of grass to about one pound of a 

 mixture of the other feeds. In four pounds of hay there would be an excess of 

 twenty parts, and in half a pound of rye an excess of five parts, total twenty- 

 five parts ; in a pound of turnips and a pound of wheat bran there would be a 

 total lack of six parts, If we add half a pound of malt sprouts we will have a 

 total lack of twenty-five parts. Hence the ration will have the proper nutritive 

 ratio. To avoid fractions we will double the quantities : 



Eight pounds orchard grass, 8:52.9 



One pound rye, : 7.0 



Two pounds turnips, . 2:11.6 



Two pounds wheat bran, 2:11.2 



One pound malt sprouts, 1: 2.2
