DAIRY FARMINC DATRYTXG. 673 



(liiction, and since sm-h feeds can be produeed ou any Tennessee farm, the dairy- 

 men of this Slate slionld resort to the jirowinj; of their own dairy feeds as a 

 relief from iiresent marlcet conditions. . . . 



"The following rotation is recommended for Tennessee: 



•'1st year: Red clover (two crops for hay, or one for hay and one for fall 

 pastnre) or alslke (one crop for hay and one for late pasture). 



•'2d year: Clover followed by soy beans. (Vetch may be sown in the beans 

 in Anjrnst and top-dressed with six loads of manure dnrini; tlu' \a Into", and 

 turned under in the sprin;; for jrreen manure). 



"3d year: Corn for srrain, stover, and silaire. 



"4th year: Oats and vetch, or rye and vetch, or barley and vetch, for jireen 

 feed or hay; or barlej', oats, or wheat for grain." 



Two milking machines have been used at the station for a year and a half. 

 The following conclusions were drawn: 



" ruder the conditions existing during the test at the station, machine 

 milking has been at least equal, if not slightly superior, to hand milking. 



" Under average conditions a cow is milked as clean with the machine as by 

 hand. An expert operator can milk cleaner with the machine than the avei-age 

 man will by hand. 



"If the teat-cups and mouthpieces are jiroperiy adjusted the machine is not 

 injurious to the teats and udder or ob.iectionable to the cows, some even pre- 

 ferring it. . . . 



"Troubles that occur in operating are du(> more to misuse than to any fault 

 of the machine." 



Records from Indiana dairy herds, O. F, IIunziker, II. .\. IIoprKK. and II. J. 

 FiDLEK (I)ifli(ina »S7«. liiil. 1.11, pji. Jl)3-216, fif/s. i?0'K— This bulletin is the result 

 of 2 years' work in collecting and arranging data concerning the annual pro- 

 duction of milk and butter fat of Indiana cows, the cost of feed per cow, the 

 relation between yield and profit, and the influence of pure-bred stock upon 

 iiroduction and profit. Records of individual herds are given with numerous 

 s\iggestions for increasing the profits of dairy herds. 



"The average of 197 yearly records was: Milk, r>.l)()l..^» lbs.; butter fat, 

 244. n lbs. 



"The best herd averaged 6,G;j(i:0 lbs. of ntilk and ;>01.1 lbs. of butter fat. The 

 jKiorest herd averaged 3.847.5 lbs. of milk and ir)2.S lbs. of butter fat. The best 

 cow produced 10,42(! lbs. of milk containing 448 lbs. of butter fat. The poorest 

 cow pri>duced 3,24S lbs. of milk containing 100 lbs. of butter fat. . . . 



" With the prices used, the best herd returned $2.58 for $1.00 in food, while 

 the poorest herd returned only $1.20. . . . 



"The average profit in graded herds was !t;.")(;.04 ; in nongraded lienls 



$r.M;2. . . . 



'■ Kven though these herds are above the average, cows were kept at a loss, 

 40 cows made less than $11 jirotit. and 21 jier cent of the herds contained UJi- 

 profitable cows. . . . 



"(Ml an average, KM) lbs. of milk cost four times as much as 1 lb. of butter 

 lat. • 



•' Tlie average profit on the 107 cows was $20.S(t. This can easily be doubled. 



'\ pure-bred dairy sire is the milk iiroducer's best investment: anything 

 short of a i»ure-bred male is too expensive at any price. 



"Since careful grading and good management have not only increased tin* 

 production of butler fal VA ll»s. per cow, Itut also reduced its cost of production 

 '5.."» <-ts. per pound, rapid improvement should be sought llirougb the continuous 

 list' of high-class dairy sires of some recognized breed.
