This means that If we are t I mgke dairying a profitable farming Operation, w* must not only get mor* cows but we muaf es|ieelslty Improve the average production of all of our cows. The Individual farmer ran do this tn three ways: First, by keeping records on th* cows he no* owns, and ibis does not mean official records, but th* actual weighing of the milk each produce* at each mllktng Totaling thia record each month and alao keeping a record on th* f«ed each co* consumes In a month, he can In a few months tell which of hla cost are the best The second way by which the farm er can Improv* the producing ability of his herd la by buying co«» which have already made creditable records proving that they do have thia ability to make a profit on r«<-l constimeli Thia Is a rather expensive «ay be- cause the fanner who has made thia record on the gooff row wants to keep her and In order to buy her.

A Hersey and Maaager Feed for Calves Where Milk Is Not Available Where milk Is not available for calves, give the following - Take 50 part a finely ground com. 15 parts lln- s«-rd oil meal. 15 parts finely ground rolled oats, 10 ¡«arts dried blood flour, 10 parts skim milk powder, one half l»art salt. Stir up with warm water at th* rate of one pound of the meal mix ture to about six pounds of water.

Better Dairy Practices to Increase Production By Increasing th* average pn*duc- tlon of hla cows about one fourth, and at the asm* time reducing hla produc tion costs one seventh. Arnold Grau* of Jackson county. Minnesota, has In creased the profit from hla cows shore cost of feed and labor, mor* than 70 times He Increased the production of hla herd by culling out the poorer cows of bls herd and replacing them with high er producing heifer* of hla own breed Ing. He cut down on his production coats by Installing an engine to run hla cream separator and by building a milk ho us* claa* to th* barn, thus re ducing th* labor of handling hla milk Egg Shipping Business Allied With Creamery A good many of the eo-operatlv* greamerlea ns well as the smaller pri vat* creameries are planning on han tiling the eggs of tbelr patrons Th* reason for thia la the feeling that th* egg shipping busloe«« la cloaely allied With the ereamerv buSlnesa Some of th* creameries which have tried thia line of work ar* voting to continue It during the coming year.
