134 PROFITABLE POULTRY PRODUCTION' 



If -the skim milk be valued at i cent a quart, 

 which is practically equivalent to 50 cents a hun- 

 dred pounds, an extremely high valuation for feed- 

 ing purposes, then the total cost of food for pen i 

 was $10.19 and for pen 2, $7.75. 



The following table shows the number of eggs 

 laid by each lot:

The pen which received the skim milk laid 248 

 eggs more than the other, or practically an extra 

 egg for every quart of skim milk they received. 

 Valuing the skim milk at i cent a quart, the food 

 cost of I dozen eggs was 9.8 cents a dozen for the 

 fowls fed the skim milk and 9.3 cents for ths other 

 lot. During the time covered by the experiment 

 the eggs produced were actually worth 20 cents a 

 dozen. The 248 extra eggs produced by pen i when 

 valued at this price were worth $4.13, which would 

 give to the skim milk a value of 1.6 cents a quart. 



In a second test 6 pens of Single Comb White 

 Leghorn fowls were employed, each pen containing 

 20 hens and 2 cocks. The experiment was divided 

 into two periods, June 30 to August 5, and August 

 6 to September 30. During the first period pens 

 I, 2 and 3 each received two quarts of skim milk 

 daily to moisten the ground feed, as in the earlier 

 experiment, while during the second period pens 

 4, 5 and 6 received the skim milk. It was found that
