636 FEEDS AND FEEDING 



kernels less thoroly than corn. For very young pigs, ground oats with 

 the hulls sifted out, or rolled oats, such as are used for human con- 

 sumption, are excellent feeds, but they are usually too expensive to form 

 much of the ration. 



947. Emmer. Emmer resembles oats closely in composition and feed- 

 ing value, and should be fed in the same manner. (233) In trials by 

 Burnett and Snyder at the Nebraska Station 33 it required 31 per ct. more 

 ground emmer than ground corn for 100 Ibs. gain when pigs were fed 

 these grains with alfalfa hay. Good results were, however, secured with 

 a mixture of half ground emmer and half ground corn. Emmer should 

 always be ground for swine. 



948. Eye In northern districts where corn is not the staple grain 

 crop for swine, rye is sometimes an economical feed. (232) Tho it 

 closely resembles wheat in composition, it is somewhat less palatable and 

 is of slightly lower value than wheat or corn. Extensive trials have been 

 carried on by Brown at the Michigan Station 34 to compare the value of 

 rye, corn, and barley for swine feeding, in which the results summarized 

 in the following table were secured. In each of 5 experiments the feeds 

 indicated in the table were self -fed, free choice, to different lots of pigs, 

 which averaged 70 to 143 Ibs. in initial weight in the various trials. The 

 grains were ground in all the trials.

It will be observed that the pigs self-fed corn and tankage made the 

 largest gains and required the least feed for 100 Ibs. gain. However, 

 the results on rye were satisfactory. Considering both the grain and 

 the tankage required for 100 Ibs. gain, ground rye was worth about 94 

 per ct. as much per ton as ground corn. There was a slightly greater 

 difference in the value of rye and corn in a trial at the Ohio Station, 35 

 while in a trial at the Kansas Station 36 ground rye was practically equal 

 to ground corn. 



In the Michigan trials and likewise in a trial at the Wyoming Station 37 

 ground rye was slightly more valuable than ground barley. On the other
