of his strain of stock and proven approximately cor- 

 rect by many trials. Elsewhere applied, certain 

 changes are allowable in correspondence with the prac- 

 tice in vogue. 



The important factors to be derived are the unit 

 values of quantity and cost applying to one feed for 

 one mature rabbit. If the feeding is done twice daily 

 it is most convenient for practice to estimate the 

 "daily normal feed" units of quantity and cost. The 

 units of quantity remain fairly constant, while the 

 units of cost vary, corresponding with feed cost prices 

 from one season to another. The herd of 12-lb. stock 

 herein discussed produces litters that average 10 lbs. 

 dressed at eight weeks of age. One doe from time of 

 mating until young are two weeks old, or for 44 days, 

 will require "normal feed." For the following four 

 weeks (28 days) until weaning time, our experiments 

 have proven that doe and litter require average dou- 

 ble "normal feed." During the two following weeks 

 (14 days), or from time of weaning until eight weeks 

 old, the litter, now separated from the doe, require 

 double "normal feed." During an average resting time 

 of five days, after being separated from her litter, until 

 mated, the doe requires "normal feed." Therefore, to 

 produce an average litter requires 44 plus 56 plus 28 

 plus 6, equals 133 "normal daily feeds." 



To ascertain the quantity and cost units of a "nor- 

 mal daily feed," we make a canvas of our herd and 

 add up the sum of our daily normal feeds on the basis 

 of the values heretofore explained : 



11 does at normal feed 11 



7 does and litter at double normal feed 14 



16 mature sale stock at normal feed.. 16 

 4 buck sale stock at normal feed 4
