076 FEEDS AND FEEDING 



that rye returned 77 cents more per bushel when harvested and fed to 

 pigs, than when the crop was hogged down, tankage being fed as a 

 supplement to both lots. As we have seen previously (942), hogging 

 down corn is a most successful practice. 



995. Gleaning stubble fields. Especially on the grain farms of the 

 West stubble fields are an important factor in economical pork produc- 

 tion. Where the grain is harvested by means of a header a consider- 

 able amount is left ungarnered and was formerly wasted. Now many 

 farmers are hog fencing their fields and turning pigs on the stubble to 

 glean the scattered heads of grain. Gains made on such waste are almost 

 clear profit. 



996. Sorghum; Japanese cane. Sorghum is too high in fiber to excel 

 as a pasture for young pigs, tho it is useful in the South for providing 

 succulence when other crops are not available. For older pigs it gives 

 somewhat better results, 143 supplied in addition to a fair allowance of 

 grain. (309) 



Scott found at the Florida Station 144 that Japanese cane fed alone 

 would not maintain young pigs. As succulence with grain this forage 

 should have about the same value as sorghum. (323) 



997. Soilage. It is not ordinarily profitable to cut and haul green 

 crops for pigs, for they can better do their own harvesting. If for any 

 reason any of the hogs can not be provided with pasture, it will help 

 to cut a little green feed for them, but it will save labor to fence off a 

 paddock in some nearby field and turn them in. (418) 



998. Roots. Roots are highly esteemed by many swine raisers, especial- 

 ly for feeding brood sows. (365-374) In several trials carried on years 

 ago roots were added to rations which were then considered satisfactory 

 for pigs, but which we now know to be inefficient. For example, pigs were 

 fed grain alone or grain and shorts alone in comparison with others fed 

 roots in addition. In 8 trials 145 pigs fed concentrates alone gained 1.2 

 Ibs. a head daily and required 499 Ibs. concentrates for 100 Ibs. gain. 

 Others fed roots in addition (sugar beets in most of the trials) gained 

 1.0 Ib. a head daily, and required 358 Ibs. concentrates plus 631 Ibs. roots 

 for 100 Ibs. gain. In these trials 448 Ibs. of roots saved 100 Ibs. of con- 

 centrates. If such a value as this could usually be secured from roots, 

 when added to modern, efficient rations, they would without question 

 often be economical winter feeds for swine, for with concentrates at 

 $25.00 a ton, roots would be worth $5.50 a ton. 



However, when roots have been added to efficient rations for brood 

 sows or fattening pigs in trials by Morrison and Bohstedt at the Wisconsin 

 Station, 146 the roots have had so low a value that they were decidedly
