Feeding Dairy Cattle 

 fermentation or heating can take place. The best method 

 is to spread it over the fields every day. In case this is not 

 possible it is at least possible to prevent leaching of the pile. 

 Heating is hard to control, but tramping it dov^^n hard will 

 help. If the manure can be stored in a place where it can 

 be tramped hard by animals very little heating will take 

 place. This might be accomplished with young stock or 

 hogs. 



III. By-Products Used in Feeding Dairy Cattle 



DAIRY farmers vv^ill be troubled to procure feed for their 

 cows during the next six months if the indications 

 at present are of any value. On account of the war 

 and the great demand for cereals for human food, good 

 prices are bound to be high even with a great crop this year. 

 Therefore this article has been planned to give some addi- 

 tional information concerning the by-products that may be 

 used in feeding dairy cows. This article may be dry read- 

 ing but it is hoped that there is valuable information in it 

 for the dairyman who will take the time to read it through. 



All the concentrates that may be used for dairy cattle 

 may be put into three groups for convenience in arranging 

 proper mixtures. These groups are a high protein group, 

 medium protein group and a low protein group. The high 

 protein group contains those feeds with a nutritive ratio of 

 I : 3 or narrower, the medium protein group those feeds 

 between i : 3 and i : 6, and the low protein group those feeds 

 with a nutritive ratio of i : 6 or wider. 



In general it may be said that a mixture of feeds in which 

 at least one-half by weight are high protein feeds will be a 

 good mixture to feed. One-third of the mixture by weight 

 should be made up of bulky feeds. The high protein feeds 

 have in general the highest manurial value and so on down 

 to the low protein feeds which have the lowest manurial 

 value. This is due to the fact that nitrogen is the most 

 valuable fertilizing constituent in feed and all the nitrogen 

 in a feed is found in the protein. Therefore the high protein 

 feeds leaving the most nitrogen would have the greatest 

 manurial value. 



Many, many farmers choose feeds according to the pro- 

 tein content of the feed almost entirely. This is a very 

 important thing to consider but is incorrect if it is the sole 

 factor considered. Feeds have a value in direct proportion 

 to the total digestible matter in them in all rations with
