the local market. A third was the 

 New England College Conference 

 formula as recommended during the 

 year 1946 for chicks and broilers. 

 These three feeds were of the usual 

 type in common usage during past 

 years. The fourth feed was a new 

 type, high energy, low fiber feed de- 

 veloped by the Connecticut Station 

 particularly for broiler feeding. It 

 is charactetrized by its content of ap- 

 proximately 70 per cent cornmeal 

 and its low fiber content, roughly 

 3 per cent or under. At the present 

 writing, such a feed is more costly to 

 produce; but with adequate supplies 

 of feedstuffs this situation will be 

 somewhat changed. 



The chicks used were obtained 

 from five crosses of White Plymouth 



Rocks. Barred Plymouth Rocks, and 

 different strains of New Hampshires 

 maintained at the University of New 

 Hampshire poultry farm. Thus, 

 each pen contained five different 

 types of chickens, each type in ap- 

 proximately equal numbers. 



The most significant figure from 

 the experiment is the income over 

 feed cost per thousand broilers 

 raised. For commercial feed A this 

 amounted to $363; for commercial 

 feed B, $387; for the New England 

 College Conference, $579, and for the 

 Connecticut Broiler ration, $611. 



A mimeographed sheet giving the 

 complete details of the experiment is 

 available for distribution.
