Since the Wolff-Lehmann Standards do not go above 30 Ibs. of 

 milk per diem it will be necessary to compare this with the Wisconsin 

 Standard as given on page 76. This Standard calls for 3-33 Ibs. 

 digestible protein, 35 -9 Ibs. dry matter and 24 '3 Ibs. digestible dr v 

 matter (digestible protein plus digestible fat x 2) for a 1,4100 

 pound cow giving from 1 -75 to 2 -00 Ibs. butter fat per diem, which 

 is the maximum such cows might be expected to give when fresh. 



The ration as suggested shows 37-105 Ibs. dry matter, 3-694 

 Ibs. digestible protein and 18 -663 Ibs. digestible carbohydrates and 

 fat, approximately the same as in the Wisconsin Standard. 



The ration as suggested might be fed as follows: 



Morning. 25 Ibs. mangels, 5 Ibs. mixed hay; 5 Ibs, oat straw; 

 and half the meal mixture, since the best way to feed the 2 Ibs. each 

 gluten meal, oats and cotton seed meal and the 5 Ibs. bran would 

 be as a meal mixture made up in those proportions. Afternoon or 

 evening, 25 Ibs. mangels, 8 Ibs. clover hay, 5 Ibs. wheat chaff and 

 half meal mixture. 



It is probable that the wheat chaff would not be all eaten fou.t 

 what was left could be thrown back for litter under the cow. 



If more concentrates were necessary, that is, if it were found 

 advisable to give some heavy producing individuals more meal, an 

 extra amount of the meal mixture described would probably be as 

 good as anything that could be fed. Making the proportion of 

 gluten or cotton seed meal 3 instead of 2 would probably be a slight 

 improvement, although any increase of the heavier meals in a mix- 

 ture must be made gradually and the effects carefully watched. 



FEEDING METHODS PRACTISED AND DAIRY RATIONS 

 FED BY CERTAIN FARMERS. 



To give the beginner some idea of what ^feeding methods are 

 actually followed in various parts of Canada letters weire sent to a 

 number of the best dairymen in each province, asking them to state 

 briefly their methods of feeding cows both summer and winter. 

 Some of the replies are summarized below. 



Further on are submitted what the' writer considers would be 

 the methods of feeding and the rations most likely to prove satis- 

 factory and profitable in the various provinces mentioned. 



In the Eastern provinces and British Columbia the ration 

 suggested is for a 1,000 Ib. cow.
