treatment and feed, with the one excep- 

 tion that one group receives in the grain 

 ration a 2 percent addition of bone flour. 

 Clover hay is the roughage fed. The re- 

 sults .so far show a very slight difference 

 in favor of the mineral feeding, as repre- 

 sented by the effect on milk production. 

 No difference has been noted so far be- 

 tween the two groups in respect to their 

 general health, reproduction, etc. 



Experiments conducted at this Station 

 have shown that when lime hydrate was 

 fed on silage the decline in milk flow was 

 checked somewhat. During the lime 

 feeding, the decline in milk flow was only 

 ..3 percent, while without the lime the de- 

 cline was 4 percent. As yet we have not 

 determined whether this beneficial action 

 was due to the addition of a mineral sup- 

 plement or to a correcting of the acidity 

 of the corn silage. The silage, however, 

 was not highly acid. Other experiments 

 in which the lime hydrate was fed in the 

 giain and on the hay have failed to show 

 similar results. Clover and alfalfa hays 

 were the roughages fed thruout this 

 work. 



We have found that feeding a mineral 

 mixture consisting of .3 parts salt, 1 part 

 bone flour, 1 part acid phosphate, and 1 

 part lime hydrate in the grain ration at 

 the rate of 4 pounds to every 100 pounds 

 of grain mixture did not lower the palat- 

 ability of the ration or cause any bad ef- 

 fect on milk on the cows. We were, 

 however, unable to detect any effect on 

 milk yield. The rations contained either 

 clover or alfalfa hay and a good grain 

 mixture. 



A number of commercial preparations 

 of mineral supplements for dairy cows 

 are now on the market. The selling 

 price of many of these is in excess of 

 their true worth. The dairyman may 

 profit by supplying mineral supplements 

 from cheaper sources. A number of 

 substances can be used: special steamed 

 bone meal (manufactured for feeding 

 purposes), floats, acid phosphate, wood 

 ashes, spent bone black, limestone dust, 

 and air-.slaked lime (when fed on sil- 

 age). The minerals can be fed in the 

 grain ration at about the rate of 2 to 4 

 pounds for every 100 pounds of grain 

 mixture, the amount depending upon the 

 kind and quality of the roughage. 



The mineral supplements may also be 

 mixed in equal parts with the salt and 

 placed w^here the cows may have ready 

 access to them. Experiments conducted 

 at this Station have shown that special 

 steamed bone meal is the most palatable 

 for this method of feeding. 



The amount of salt needed by the cow 

 will vary with the kind and amounts of 

 feed consumed. A heavy silage ration 

 seems to call for large amounts of salt. 

 It is good practice to add from % to 1 

 pound of salt to every 100 pounds of 

 grain mixture; and, as a safety precau-
