ANIMAL PRODUCTION. 869 



These results indicate that hominy feed has a feeding value for swine about 

 10 to 15 per cent greater than that of an equal weight of ground corn. 



In experiments comparing corn, wheat, and middlings four lots of Ave 110-lb. 

 pigs were fed during a 91-day period, lot 1 receiving ground corn and tankage 

 9 : 1, lot 2 ground wheat and tankage 9 : 1, lot 3 middlings and tankage 9 : 1, and 

 lot 4 middlings alone, and made 1.57, 1.59, 1.52, and 1.44 lbs. average daily gain 

 per head for the respective lots, requiring 3.66, 3.83, 3.72, and 3.65 lbs. of feed 

 per pound of gain. 



Comparing corn and rye, two lots of four and six 44-lb. pigs were fed during 

 a 49-day period, lot 1 receiving corn and tankage 9 : 1 and lot 2 hogged-down rye 

 and tankage, and made 0.46 and 0.51 lbs. average daily gain per head, requiring 

 448 and 372 lbs. of feed per 100 lbs. gain. These same pigs were put in a dry 

 lot, lot 1 on corn and tankage as before, and lot 2 on rye and tankage, and 

 fed during a 112-day period, making 1.09 and 1 lbs. average daily gain per 

 head, and requiring 3.99 and 4.41 lbs. of feed per pound of gain. 



In an experiment comparing light and heavy grain rations on rape pasture 

 with a heavy grain ration in dry lot, five lots of 16-week-old pigs were fed 

 during a 77-day period, lot 1 receiving corn and tankage 9 : 1, full feed in dry 

 lot; lot 2 corn, full feed on rape pasture; lot 3 com, f full feed, on rape pasture; 

 lot 4 corn and tankage 9 : 1, full feed, on rape pasture ; and lot 5 corn and 

 tankage 9 : 1, f full feed, on rape pasture. The lots made 0.9, 1.21, 1.06, 1.47, 

 and 1.2 lbs. average daily gain i>er pig for the respective lots, and consumed 

 3.847, 3.254, 2.781, 3.166, and 2.94 lbs. concentrates per pound of gain. 



The results of this experiment, as well as those of experiments previously re- 

 ported (E. S. R., 28, p. 468) indicate that "by feeding a light grain ration on 

 pasture, gains may be produced at a much smaller expenditure for grain, 

 though less rapidly, than by feeding a heavy grain ration on pasture, and also 

 that the use of green feeds in connection with com greatly diminishes the need 

 for nitrogenous concentrates that exists in dry lot feeding." 



Ground wheat versus whole wheat for fattening pigs, R. K. Buss and 

 C. B. Lee (Nebraska Sta. Bui. lU {19 U), PP- 3-13, figs. 3).— Four lots of 10 

 pigs each weighing approximately 138 lbs. made average daily gains per pig 

 during an 84-day feeding period of 0.84, 1.09, 1.19, and 1.32 lbs., respectively, 

 at a cost per pound of gain of 7.39, 6.67, 5.38, and 6.07 cts., respectively. Lot 3, 

 fed soaked ground wheat, consumed 4.43 lbs. of wheat per pound of gain, while 

 lot 1, fed soaked whole wheat, consumed 5.91 lbs. Grinding the wheat resulted 

 in a net saving of 21 cts. per bushel. Lot 4, fed ground wheat and tankage, con- 

 sumed 4.215 lbs. of grain and 2.07 lbs. of tankage per pound of gain, while lot 2, 

 fed a similar mixture of whole wheat and tankage, consumed 4.858 lbs. of wheat 

 and 2.39 lbs. of tankage, so that grinding the wheat resulted in a net saving of 

 7 cts. per bushel. The addition of 5 per cent of tankage proved much more 

 efficient in reducing the amount of wheat required to produce a pound of gain 

 when fed with whole wheat than it did when fed with ground wheat. Consid- 

 erable whole wheat passed through the pigs of lot 1 and 2, and it was appar- 

 ently better digested when fed with tankage. At the end of the eighth week 

 of feeding the lots had made 42, 56.7, 56.5, and 67.5 lbs. total gain per pig, 

 respectively; at the end of the tenth week. 57, 73, 76, and 90 lbs., and at the 

 end of the twelfth week 70.5, 91.6. 100, and 110.8 lbs., respectively. 



Five lots of nine pigs each weighing approximately 108 lbs., were fed during 

 a 98-day period as follows: Lot 1 shelled corn dry; lot 2 whole wheat dry; 

 lot 3 whole wheat soaked; lot 4 ground wheat moistened; and lot 5 ground 

 wheat soaked. The test was duplicated and the results of the two tests aver- 

 aged. The average daily gains per head for each lot were 1.11, 1.02, 1.05, 1.36, 

 and 1.41 lbs., respectively, the cost per pound of gain being 5.48, 6.42. 6.35, 5.64,
