90 HATCH EXPERIMENT STATION. [Jan. 



Eggs from both lots of fowls were tested under numbers 

 by two families. One family reports no difference ; the 

 other found the eggs from the hens not getting the powder 

 "much preferable" to the others. 



Conclusion. 



A study of the figures showing results shows that the 

 hens not getting the condition powder laid more eggs, of 

 practically the same average weight. The food required to 

 produce a single egg was less, and the cost was very ma- 

 terially less. The average weight of the fowls not getting 

 the powder at the close of the experiment was about one- 

 quarter of a pound less than that of the other. 



We have now carried through three experiments to test 

 the value of condition powder for egg-production. The 

 differences have in every case been small. In favor of 

 the condition powder we have one experiment, against it 

 we have two experiments. It is not, however, my disposi- 

 tion to claim that the powder is injurious, but simply that it 

 is not beneficial. This the four experiments, carried out 

 with the utmost fairness and with every care, certainly 

 prove. In the light of these results, it is believed that 

 poultry keepers throw away money expended for condition 

 powder. 



2. Animal Meal v. Cut Bone for Egg-production (Decem- 

 ber 12 to April 30). 



In this experiment there were nineteen pullets in each 

 house when the experiment began. Those in the animal- 

 meal house weighed 101.5 pounds, and had laid, November 

 8 to December 12, 82 eggs. The pullets in the cut-bone 

 coop weighed 101.25 pounds, and had laid 41 eggs. 



In the morning mash of one lot one part animal meal to 

 five parts total dry materials was used ; in the mash of the 

 other lot, the same proportion of fresh-cut bone was mixed. 

 The large, flat bones, comparatively free from meat or fat, 

 were used. 



In the animal-meal coop the health of the birds was good, 

 but one fowl being out of condition in any way. She be-
