Feeding Dairy Cattle 

 of potash as purchased in commercial fertilizers. There- 

 fore, when a man purchases a high protein feed, such as 

 cottonseed meal or oil meal, he can make a substantial reduc- 

 tion from the first cost price of the manurial value of these 

 high protein feeds when the manure and urine are properly 

 conserved. 



FEEDING COTTONSEED MEAL 



Cottonseed meal is a valuable source of protein and about 

 the cheapest source of protein that we have during most 

 years. This feed is particularly valuable for feeding dairy 

 cattle, because when used in reasonable quantities in the 

 mixture no harm seems to come from it. I usually advise 

 that the cottonseed meal in a given mixture of concentrates 

 for dairy cows should not exceed 40 per cent, of the mixture 

 by weight. If gluten feed is being fed in the same mixture, 

 I would not have the gluten and the cottonseed together 

 exceed 40 per cent, of the mixture of concentrates 1)y weight. 

 There is a feeling that cottonseed meal feeding has a bad 

 influence on tbe udder and that animals fed highly on cotton- 

 seed meal are predisposed to garget and other udder troubles. 

 Also there is a feeling that high protein feeding, par- 

 ticularly of cottonseed meal will produce a harsh feeling 

 hide, poor handling qualities and rough stary coat. How- 

 ever, admitting all of these criticisms to be more or less true. 

 I still feel that we must make a large use of cottonseed meal 

 in our dairy cow rations. 



I would not feed cottonseed meal to horses, to hogs or 

 to cattle under one year old. It is of great value as a pro- 

 tein supplement in rations for beef cattle. The general 

 efJect of cottonseed meal in feeds is constipating, and cotton- 

 seed meal is not advised if linseed meal is as cheap when 

 there is no silage in the ration. 



LINSEED OIL MEAL 



One of the most useful feeds to the American farmer is 

 oil meal from flax. Flax itself is too valuable for the oil it 

 contains to be used as such for feeding although a small 

 amount of ground flax seed is sometimes fed to calves. 



In the manufacture of oil the flaxseed is ground, warmed 

 up and the linseed oil pressed out leaving the cake behind. 

 Most farmers like their oil meal ground up. European 

 farmers who import much oil meal like it best in the form of 

 the slabs just as they come from the press and break up these 

 slabs in their own way. This is a sure way of not getting 

 adulterated meal. This oil cake broken up into nut or pea
