Use it to cut your cost 
of milk production 
The only feed which counts is the feed which a cow 
digests. Every cow in your barn must get approximately 
8 lbs. of digestible feed a day to maintain herself. In addition 
she must get 3 lbs. of digestible feed for each 10 lbs. of 
milk she gives. 
This means that in order to get 40 lbs. of milk a day 
you must furnish a cow with at least 20 lbs. of digestible 
feed, and of this J lbs . must be digestible protein . 
The most effective way to cut down your feed bill is to 
raise as much digestible feed as possible, particularly digesible 
protein since digestible protein is scarce and very expensive 
to purchase. 
G.L.F. Clover and Alfalfa Seed insure a supply of home-grown Protein 
The average yield of hay per acre in the United States is 
Yield per acre, Lbs. Digestible Protein, Lbs. Digestible Material, Lbs. 
Alfalfa hay 43 72 463 7.250 
Clover hay 2624 199 1336

This table shows that alfalfa and clover hay are the best sources of *■ 
home-grown protein. The biggest factor in securing good crops of alfalfa 
and clover is seed that will not winterkill. 
G.L.F. seed, purchased for you by your representative in the north 
and west, is winter resistant. 
Buy G.L.F. seed to raise more digestible feed, particularly more 
digestible protein, and thereby cut the cost of your feed bill. 
G.L.F. Rations are the economical source of additional digestible material 
A cow cannot eat enough roughage to give her all the digestible 
nutrients she needs to produce the most milk. Grow legume hay and 
buy G.L.F. feed to effectually supplement it. 
The formulas for G.L.F. feed-are supplied and backed by fourteen 
agricultural colleges. 
Because the formulas are public you can tell exactly what ingredients 
are in G.L.F. feeds; how many pounds of digestible nutrients they con¬ 
tain; and the cost per hundred pounds of digestible material.
