RATIONS FOR DAIRY CATTLE 



193 



The amount of concentrated food may be calculated 

 for each cow by allowing 



(a) J Ib. for every 100 Ibs. live weight of cow; 

 () 2 to 2j Ibs. for every gallon of milk produced 

 per day, i.e. \ Ib. for every quart. 



With a cow of 800 Ibs. live weight, and yielding 

 3 galls, milk per day, the amount required would be 

 (a) 8 x i = 2, (&) 3 X 2 = 6 ; i.e. 8 Ibs. in all per day. 



The following mixtures of concentrates x for winter 

 milk production are arranged for a cow of 800 Ibs. which 

 is giving 3 galls, milk per day. A 15i O 4 F 7 means that its 

 composition works out to be : albuminoids, 15 \ per cent. ; 

 oil, 4 per cent. ; and fibre, 7 per cent.
