Stewart & Atwood* report results comparing a ration made up of 

 a mixture of grains with one in which corn meal was the principal 

 constituent. The fowls fed the nitrogenous (narrow) ration pro- 

 duced 79 per cent more eggs of a value 64 per cent greater than the 

 other lot. In these experiments the fowls receiving the nitrogenous 

 ration received ground fresh meat and bone, while the other fowls 

 had no animal food. A second test gave results in accord with the 

 first. 



Drydenf in comparing wheat with corn reports results in favor of the 

 wheat ration both in number of eggs produced and in cost. In these 

 experiments, dried blood was used as animal food, but not in equal 

 quantities for the two lots of fowls under comparison. 



Taylor^ reports a trial of narrow, medium and wide rations for 

 laying fowls, showing the egg production to be larger in proportion 

 as the ratio is narrow. The highest egg yield was obtained upon a 

 narrow ration, while the medium ration ranked next. In these trials 

 the amount of animal food given was greater the narrower the ration. 



In view of the frequently demonstrated superiority of animal sub- 

 stances over vegetable substances as a source of protein, the writer 

 is not surprised that in the experiments at Cornell, in West Virginia 

 and in Utah, the fowls receiving a narrow ration produced the 

 more eggs, for in all these cases these fowls received a generous 

 supply of animal food, while the fowls on the wider ration either 

 received no animal food or received it in smaller quantity than the 

 other fowls. 



The writer believes that the results of his ex- 

 Conclusion, periments justify the conclusion that corn and 

 corn meal may safely and wisely be made very 

 prominent in the rations of laying hens. It is necessary, however, 

 to use in connection with these feeds a liberal amount of animal food 

 of some sort. The results obtained in the other stations above 

 referred to are sufficiently accounted for by the fact that the corn 

 ration was not supplemented with animal food. With a suitable 

 quantity of animal food, it is possible to produce very satisfactory 

 yields of eggs where corn and corn meal comprise the greater part 

 of the grain fed. One of the most satisfactory rations used was 

 made up as follows :
