SOME MODERN LAYING RATIONS. 



(Standardized war rations appended for comparison.) 



Appreciating the need i'or, and importance of, standardizing laying rations 

 recommended by various State Colleges, and largely used by poultrymen, a 

 conference of representatives of Cornell University, Connecticut Agricultural 

 College, Massachusetts Agricultural College and the State University of New 

 Jersey, was held in New York City on November 22, 1917. This conference 

 evolved the following rations, and recommended methods of feeding. The 

 special problems which had to be met in the work of standardization were the 

 necessity of getting a um'forrn ration acceptable to a majority of users: the 

 problem of choosing ingredients which would be most generally available and 

 which would be adjustable within certain restrictions to changes in supply, 

 prices, and Government regulations, and lastly but most important the problem 

 of maintaining at all times the proper amount and proportion of digestible 

 feed nutrients at economical cost. With these thoughts in mind the following 

 rations were finally decided upon and approved as the basis for such standard- 

 ization. 



Standardized War Rations for Poultry. 

 Scratch Ration. 



Cracked corn 500 Ibs. 



Feed wheat 100 Ibs. 



Heavy oats 200 Ibs. 



Barley 200 Ibs. 



Total 1000 Ibs. 



Since the Government had regulated the quantity of wheat in poultry 

 rations at not over 10 per cent, this amount was used in the standard scratch 

 ration. 



In order to allow the mixer to adjust the amounts of the various ingredients 

 so as to take advantage of supply and variation in prices, the following varia- 

 tion in the amounts of each constituent is allowed. Cracked corn may vary 

 from 40 to 60 per cent of the total ration, or from 400 to 600 pounds in each 

 1000-pound mixture. Feed wheat was to be constant at 10 per cent, or 100 

 pounds in each 1000-pound mixture. Oats and barley each may also vary from 

 10 to 30 per cent, or from 100 to 300 pounds in each 1000-pound mixture. 



The above changes, however, should be made within the above-stated 

 ranges, and in such amounts that the combined mixture shall have at least 10 

 per cent of protein, 68 per cent of carbohydrate, 4 per cent of fat and not over 

 5 per cent of fiber. 



The above standardized scratch ration contains approximately the fol- 

 lowing nutrients, which it is expected will vary slightly with the quality of 

 grains used: 



11.1 per cent of protein, 

 72.6 per cent of carbohydrates, 

 4.1 per cent of fat, 

 4.6 per cent of fiber. 



Standardized War Mas/*. After careful consideration the following stand- 

 ardized mash was adopted as being the best mash mixture, to supplement the 

 previous grain ration, which it is possible to mix, considering the amount and
