rich supplements gained 1.20 Ibs. daily, compared with 1.60 Ibs. for 

 pigs fed ground corn in place of sorghum and 1.49 Ibs. for others fed 

 ground kafir. In these trials ground sorghum was worth only 63 per ct. 

 as much per 100 Ibs. as ground corn and only 70 per ct. as much as 

 ground kafir. In a trial at the Oklahoma Station 47 ground sorghum seed 

 was worth 78 per ct. as much as corn, while in a trial at the Nebraska 

 Station 48 ground sorghum seed was worth only 68 per ct. as much as 

 ground corn when fed with alfalfa hay. The pigs gained only 1.15 Ibs. 

 a day on sorghum, while those fed corn gained 1.69 Ibs. On a mixture 

 of half sorghum and half corn the gains were more rapid, but the value 

 of the sorghum per 100 Ibs. compared with corn was about the same.

Darso, an early-maturing variety of the sweet sorghums, produced 

 practically as rapid gains as corn or kafir in a trial by Malone at the 

 Oklahoma Station 49 in which tankage was fed as the supplement. How- 

 ever, the pigs fed darso required considerably more feed for 100 Ibs. 

 gain, and hence the darso was actually worth only about three-fourths 

 as much as ground corn per 100 Ibs. In a later experiment darso was 

 worth 95 per ct. as much as corn. (241) 



952. Millet. Proso, or hog millet, which is sometimes raised for grain 

 in the northern plains states, is a satisfactory feed for swine when 

 ground, but ranks somewhat below ground barley in feeding value. 50 

 (243) As millet is a carbonaceous grain, it should be supplemented by 

 a suitable protein-rich concentrate. 



953. Buckwheat. Buckwheat is rarely used for stock feeding and is 

 less valuable for this purpose than corn, owing to the woody hulls. In 

 Canadian trials 51 buckwheat has been slightly inferior to wheat or wheat 

 middlings for fattening pigs. Buckwheat tends to produce poor quality 

 bacon when it forms a large part of the ration, 52 and it may also cause 

 skin eruptions on the pigs. (244) 



954. Screenings; weed seeds. Only the heavier grades of screenings, 

 containing little chaff and consisting of broken or shrunken wheat, weed 

 seeds, etc., are at all suitable for swine. Screenings should always be 

 ground for swine and had best be mixed with more palatable feeds. At 

 theWisconsin Station 53 Henry found that pigs refused to eat any large 

 quantity of raw pigeon-grass seed meal, but they ate it readily after it 

 was cooked. A mixture of 2 parts of the cooked meal and 1 part of corn 

 meal gave as good results as corn meal. In a Manitoba trial 54 100 Ibs. of
