ANIMAL PRODUCTION. 371 



produced an average daily gain per head of 0.97 lb., costing S.35 cts. per pound 

 of gain, with a ration of corn and tankage 9:1 the corresponding values were 

 0.54 lb., and 7.16 cts. ; with corn, shorts, and cowpea pasture 0.94 lb., and 8.96 

 CIS.; and with corn and cowpea pasture 0.9 lb. and 8.8 cts. In another test, 

 with rice polish and tankage 9: 1, there was produced 0.9 lb. average daily gain 

 per head as compared with 0.94 lb. corn and tankage 9:1 and 1.08 lbs. with 

 a field of com and cowpeas " hogged off." The respective costs were 5.03. 

 4.81, and 4.32 cts. per iwund of gain. 



Experiments in comparing soy bean, coAvpea, and velvet bean pastures as 

 grazing crops for hogs were inconclusive, as most of the pastures were unsatis- 

 factory. There was a saving of dry feed effected by the use of these pastures, 

 but large areas were required. 



In 3 separate tests in which 45 hogs weighing from 45 to 80 lbs. were used, 

 lot 1, fed on corn alone, proved uns{itisfactorj% with an average daily gain per 

 head of approximately 0.4 lb., at a cost ninging from 7.55 cts. per 1 lb. gain to 

 11.14 cts. Lot 2, fed corn and wheat shorts 2:1, produce<l approximately 0.S4 

 lb. average daily gain, costing from 6.62 to 8 cts. per pound of gain ; and lot 

 3. fe<^l corn and skim milk 1 : 2.2, produced an average daily gain of 1.33 lbs., 

 costing from 4.95 to 6.77 cts. per pound of gain. 



Swine feeding' experiments with soy-bean meal, E. Haselhoff {Fiihliiiff's 

 Landic. Ztg., 61 {1912), No. 12, pp. 401-114; abs. m Zenthl. Agr. Chem., J,t 

 (1912), No. 11, pp. 77^-777).— This is a report of experiments with 36 pigs, 

 testing the feeding value of soy-bean meal as compared with other concentrated 

 feeds. 



Three lots of 4 pigs each, fed a basal ration of ground corn and wheat, pota- 

 toes, and skim milk, in addition to the special feed gave the following results: 

 Lot 1, fed barley grain and meat meal, produced 100 kg. gain at a cost of 89.43 

 marks (9.67 cts. per pound): lot 2, fed sesame meal, for 89.63 marks; and 

 lot 3, fed soy-bean meal, for 87.38 marks. In a second experiment, 2 lots of 

 6 pigs each, fed barley grain in addition to a basal ration of potatoes, rape, corn, 

 and fish meal, produced 100 kg. of gain at a cost of 99.16 marks, and 2 other 

 lots, fed soy-bean meal, for 92.74 marks. 



Cooked pig feed, S. Spencer {Live Stock Jour. [London], 77 {1913), No. 

 203S, p. 'I'l^). — This is a discussion of the results of 4 experiments conducted at 

 the experiment station, Clonakilty, Ireland, to ascertain the value of cooked 

 food for pigs. 



On a ration of cooked potatoes, carrots, meal (com and barley), milk, and 

 alfalfa, 17 3-month-old pigs made an average daily gain of 1.2 lbs. per pig, re- 

 quiring 3.23 lbs. dry matter to produce 1 lb. live weight. Seventeen other pigs 

 fed a similar ration, uncooked, made an average daily gain of 1.32 lbs., requir- 

 ing 2.96 lbs. dry matter to produce 1 lb. live weight. The results indicated that 

 the uncooked feed produced greater gains on less feed and at a lower cost, and 

 that the pex-centage of offal was less than with pigs fed the cooked feed.
