The figures in the table vary considerably, although it may be 
stated that the amount of buttermilk in the feed affects the compari- 
sons by increasing the amount of moisture in the droppings, espec: Qy 
during hot weather. The manure when weighed was soft and wet, 
so that the dry weight would be very much smaller- The birds 
more feed as they increase in sizx bsj ecially during cool weather. 
DIGESTIBLE PROTEIN AND ENERGY VALUES OF THE RATIONS. 
The protein and the energy values of the various rations > 
these fattening experiments show clearly the effect of thick con- 
densed buttermilk, tallow, and oat flour in fattening. The follow- 
ing prices of grain and milk per 100 pounds were used: Corn meal,

^_ _" ndensed buttermilk, SI; and ordinary buttermilk - _" 
Farmers' Bulletin 346. United Si fees Department of Agriculture, 
entitled " The Computation of Rations for Farm Animals by the Use 
of Energy Values." was used in deriving the protein and energy 
values of these feeds. Sixty per cent of the total feed was - 
mated as buttermilk in figuring the effe : : :^e buttermilk on the 
energy value of the feed.
