640 FEEDS AND FEEDING 



lambs' quarter seed screened from wheat equalled 60 Ibs. of mixed grain 

 for pigs, when fed as only one-fifth the ration. 



955. Miscellaneous carbonaceous feeds; mixed feeds. Rough rice, when 

 ground, may be used as a substitute for other grain when it is cheap in 

 price. 55 Owing to the hulls, it is nearly as high as oats in fiber and 

 hence worth considerably less per pound than corn. (234) 



Rice polish has proven to be worth even more than corn for fattening 

 pigs. In 4 trials by Dvorachek at the Arkansas Station 56 100 Ibs. of 

 rice polish was equal to 125 Ibs. of ground corn, when both were properly 

 supplemented with tankage, skim milk, or buttermilk. Rice polish did 

 not, however, prove as palatable as corn, especially toward the close of 

 the fattening period, and when large quantities were fed it tended to 

 cause scours unless it was thoroly soaked for 12 to 24 hours before 

 feeding or unless lime water was given the pigs. 



Rice bran is often an economical feed for swine in the rice growing 

 districts of the South, but feeding too large a proportion of this feed 

 produces soft pork, which is discounted by the packers. From trials at 

 the Texas Station 57 it appears that rice bran may be fed with equal parts 

 of corn grain and sorghum, and 10 per ct. tankage without causing soft 

 pork, and in all probability the rice bran may even form 60 per ct. of 

 the ration without injuring the pork. In trials at the Arkansas Sta- 

 tion 58 rice bran was worth about 90 per ct. as much as ground corn, while 

 in a Texas trial 59 it was worth only about three-fourths as much per 100 

 Ibs. as corn. 



Molasses, either beet or cane, is used less commonly for feeding swine 

 than for cattle, horses, or sheep. "When cheaper than corn or other grain, 

 molasses may be substituted for a part of the grain in the ration of 

 swine. (277, 280) When fed as a partial substitute for grain or other 

 concentrates, cane molasses was worth about as much, pound for pound, 

 as ground barley or wheat mixed feed in trials at the Oregon Station, 60 

 but in an experiment at the Mississippi Station 61 it took 1.8 to 1.9 Ibs. 

 molasses to equal 1 Ib. of corn. In a trial at the New Jersey Station 62 

 with brood sows satisfactory results were secured, when 2.3 Ibs. cane 

 molasses was substituted for part of the corn in a ration of corn, tank- 

 age, alfalfa hay, and mangels, but the molasses was worth less per pound 

 than corn. The outcome was unsatisfactory when molasses was substi- 

 tuted for all the corn in the ration. 



Beet molasses is apt to cause scours in pigs unless they are started 

 on it very gradually and only limited amounts are fed. 63
