character of the nutrients provided, together with probable prices and supply 

 of feeding stuffs during the coming years: 



Wheat bran 100 Ibs. 



Wheat middlings 100 Ibs. 



Corn meal or corn feed meal or hominy . . 100 Ibs. 



Gluten feed 100 Ibs. 



Crushed or ground oats 100 Ibs. 



Meat scrap 100 Ibs. 



Total 600 Ibs. 



No modifications are usual in the mixing of this mash, as it is not deemed 

 that such will be necessary or appropriate, and furthermore, even slight changes 

 in the relative proportions of the various constituents might be of such a nature 

 as to injure the balance of the ration materially. In order that only good 

 standard grades of various feeding stuffs shall be used, the following analysis 

 should be guaranteed, namely, not less than 20 per cent of protein, 58 per cent 

 of carbohydrates, 5 per cent of fat and not more than 7 per cent of fiber. 

 This mash mixture contains approximately, depending on the quality of the 

 ingredients, 22 per cent of protein, 60 per cent of carbohydrates, 5 per cent of 

 fat and 5.8 per cent of fiber. 



Rules for Feeding. These rations are designed for the complete feeding 

 of laying hens, the mash ration being especially designed for feeding in self- 

 feeding hoppers, and the grain ration preferably fed in deep litter. 



Of equal importance with the adoption of suitable rations is the question 

 of the proper amounts of each to feed. A general recommendation is herewith 

 made regarding this point, namely, that to the average flock of hens these 

 rations be fed in approximately equal amounts of mash and grain. In cases 

 of extremely heavy production, it will be desirable to induce a greater con- 

 sumption of mash by restricting the amount of grain feed. On the other hand, 

 to breeding stock, or to birds producing only moderately, it may be desirable 

 to feed slightly increased amounts of grain. Two important advantages are 

 gained by feeding considerable quantities of the mash; first, it carries a higher 

 protein content, which nutrient is especially necessary for egg production; 

 second, the mash being the cheaper mixture, a considerable consumption of 

 this part of the ration results in lessened cost of total feed consumed. 



Vineland International Contest Rations: The wonderful and persistent 

 laying records made during the years 1915-1919 at the Vineland International 

 Egg Laying and Breeding Contest have occasioned much interest and dis- 

 cussion as to the feeds used and the methods of feeding. 



The Vineland Rations follow: 



Contest Mash. 



Wheat bran 100 Ibs. 



Wheat middlings, white or flour 100 Ibs. 



Ground oats, standard or better 100 Ibs. 



Corn meal, pure 100 Ibs. 



Meat scrap, 50 per cent protein 100 Ibs. 



This dry mash contains considerable variety, the ingredients are readily 

 obtainable and being in 100 Ib. quantities can be easily mixed. This dry mash 

 contains 18.2 per cent of protein, and 49.9 per cent of carbohydrates. The 

 nutritive ration is 1 to 2.8. 



Supplementing this dry mash the contest birds were given morning and 

 night in deep litter the following grain ration :
