148 THE CORNING EGG FARM BOOK 



Now, the mustard used in this experiment was 

 highly concentrated table mustard, and while the cost, 

 where only six hens were being fed with it, amounted 

 to very little, on a large plant like The Corning Farm, 

 the question of cost becomes a serious item. Whether 

 to feed concentrated mustard or a mustard bran was 

 found to be worthy of careful consideration, because 

 it was impossible to get nearly as perfect a mixture 

 in the Mash, with a small quantity of highly concen- 

 trated mustard, as with a mustard not so strong but 

 running three times the amount in bulk. As an illus- 

 tration of the advisability of introducing the mustard 

 in form of bran we might say that, by using a small 

 quantity of one certain meal carrying a very high 

 percentage of protein, it would be possible to intro- 

 duce into the Mash the amount of protein desired, but 

 by using a number of meals, each carrying a small 

 percentage of protein, a much better Mash results, 

 and every bird is able to get its due and necessary 

 proportion of the ingredients. 



Mustard Increases Fertility 



The three pens before mentioned, after being fed 

 as described through the Winter months, were mated 

 in the month of March, and it was found that the 

 fertility of the eggs of the mustard fed pen far ex- 

 ceeded that of either of the other pens, and that the 

 resulting chicks were much stronger, developed bet- 

 ter, and were altogether more desirable than the
