REAL NUTRITIVE VALUE OF FOODSTUFFS 41 



In other words, 100 lbs. of oats fed to a horse is 

 equivalent to 60*14 lbs. of digested starch for the supply 

 of heat or energy. 



II. Meadow Hay. 



So that 100 lbs. of meadow hay fed to a horse is 

 euivalent to 32*1 lbs. of digested starch. 



The *' nitrogenous ratio " of oats is : 

 N 8-99 



8-99 



(F X 2-3) + C. -H. -f D.F. ~ (3-6 x 2-3) + 43-5 -f 2-7 " 5448 ~ 6-06 ; 

 i.e.y a ratio of 1 : 6. 



The '' fatty ratio " of oats is : 



F_3;6 1^. 



N ~ 8-99 ~ 2-5' 

 i.e., a ratio of 1 : 2-5. 

 The " nitrogenous ratio " of hay is — 



N 7 7 1 



(P X 2-3) + C.-H. + D.F. ~ (0-58 x 2-3) -f 24-7 + 10-62 ~ 36-65 ~ 5 -23 

 i.e., a ratio of 1 : 5'23. 



* Since hay contains 23-1 per cent, of crude fibre (see p. 36).
