130 PROGRESSIVE POULTRY CULTURE 



ing rations take the case of the sample ration suggested 

 for laying hens of 3 to 5 Ibs. live weight. 



Consulting Talblie A for the necessary data/ and tak- 

 ing, to start with, 3 Ibs. of corn and- 2 11>s<. of wheat 

 the constituents are written in tabular form. By add- 

 ing the columns of nutrients and comparing with the 

 standard it is seen that the totals are not sufficient and 

 that the fuel value isi too small. Computation shows 

 that the nutritive ratio (1:9) is altogether too wid^e. 



Bringing to the ration 1 1T>. of beef scraps, adding 

 and computing again, shows on comparison with the 

 standard 1 that, although much nearer right than before, 

 it is still lacking. 



On pound of cut clover hay added to the three 

 previous items gives a ration* that is quite close to the 

 demands of the standard. Adding a pound 1 of skim- 

 mil'k makes this laying ration almost exactly correspond 

 to the standard. 



The successive steps in reckoning this ration are 

 given together as follows:
