WING'S METHOD OF BALANCING RATIONS 



A short method of balancing rations devised by H. H. 

 Wing is practical and convenient. 



He divides the ordniary grains into three groups : low pro- 

 tein (less than 12 per cent) ; medium protein (12 to 25 per 

 cent) ; high protein (over 25 per cent). The figures given 

 in the table are for the total and not the digestible protein. 



TABLE 52. WING'S METHOD OF BALANCING RATIONS 



Mixed hay, corn silage, and corn fodder are very similar 

 in composition as far as the relation between the protein and 

 carbohydrates is concerned. When roughage of this class 

 is used, a grain mixture made by mixing equal parts by 

 weight of one from each of the three groups will make a well- 

 balanced ration. A dairy cow in full flow of milk should 

 receive all the hay and silage she will eat and the grain mix- 

 ture at the rate of one pound for each 3 or 3 pounds of 

 milk that she produces, if this milk be about the average 

 composition of 4, percent. If the milk contains 3 to 3.5 

 percent fat, 1 pound grain to 4 pounds of milk is sufficient. 

 If alfalfa hay is used the high protein feed is not necessary.
