784 EXPERIMENT STATION RECORD. 



tropseolin 000, metanil yellow, Bismarck brown, cinnamon (10 parts oil 

 of cinnamon and 90 parts alcohol), formol, salicylic acid, wintergreen, 

 peppermint, chrysoidin, saffraniD, and methylene bine on pancreatic and 

 peptic digestion. Different quantities of the several substances were 

 added to solutions of peptic and pancreatic ferments and the effect on 

 digestibility of albumen was observed. It was found that picric acid, 

 tropseolin 000, and metanil yellow hindered peptic digestion; Bismarck 

 brown, cinnamon, and formol hindered pancreatic digestion; winter- 

 green and salicylic acid partially arrested peptic digestion ; and pepper- 

 mint, chrysoidin, saffranin, and methylene blue had no apparent effect 

 on the action of either of the ferments. 



Silage for hogs, D. O. Kouesb ( Virginia 8ta. Bui. 68, pp. 101-105). — 

 Two tests were made to study the value of silage in a maintenance 

 ration for pigs. The first was made with 2 lots of sows. Lot 1 con- 

 sisted of a Poland-China and a Berkshire, and lot 2 of 2 Poland-Chinas. 

 The pigs in lot 1 were fed per week 17i and 14 lbs., respectively, of 

 com on the cob. Those in lot 2 were fed 50 and 49 lbs. of silage per 

 week, respectively. Some of this (about 10 lbs.) was wasted, but the 

 amount was not accurately determined. 



1 hiring the 7 weeks of the test lot 1 lost 3.5 lbs. and lot 2 27 lbs. The 

 pigs were in poor condition at the close of the test. Beckoning silage 

 at 82 per ton and corn at 35 cts. per bushel, the silage was much the 

 cheaper food. The animals were fattened after the close of the test, 

 and no difference was observed in the 2 lots. 



In the second test the value of silage as part of a ration was studied. 

 A boar and a sow were each fed about 21 lbs. of corn on the cob and 

 35 lbs. of silage per week; another sow was fed 14 lbs. of corn on the 

 cob and 28 lbs. of silage. During the 10 weeks of the test the boar 

 lost 18 lbs., and the sow fed the same ration lost lbs., while the sow 

 fed the smaller ration gained 13 lbs. The pigs appeared in good con- 

 dition. 



On the basis of the values mentioned above the pecuniary value of 

 silage is discussed. "So far as the above results are concerned, we 

 should say silage was economical to use in conjunction with corn as a 

 maintenance ration, but not so if used aloue." 



Feeding experiments with chickens, T. D. Hinebaucii {North 

 Dakota Sta. Rpt. 1896, pp. 16-18). — Brief statements are made concern- 

 ing the condition of the poultry department at the station. 



A test was made to determine whether heating a poultry house 

 diminished the cost of feeding and increased the egg production. 

 Forty-six chickens were fed in an un warmed poultry house from Decem- 

 ber 1 until January 20. At the beginning of the test they were fed 5 

 lbs. of tabic scraps in the morning and 2 lbs. of wheat screenings at 

 night. Afterwards the ration was increased until they consumed llf 

 lbs. of scraps in the morning and 11£ lbs. of wheat screenings in the 

 evening.
