EXPERIMENT STATION RECORD. 



authors rejxirt analyses of the feeding stuffs used, and discuss liriefl}' the method of 

 manufacturing tankage and l)eef meaL Briefly stated these products consist of meat 

 scraps, fat trimmings, and scrap bones cooked by steam under pressure. After the 

 fat is removed the resulting product is dried, pressed, and ground. 



Five lots of 6 cross-bred pigs each were used in the test. Lot 1 was fed corn 

 meal only, consuming when on full feed 10 lbs. per head daily. Lots 2, 3, and 4 

 were fed, respectively. Darling's Beef Meal, Swift's Digester Tankage, and Armour's 

 Tankage in addition to corn meal, consuming when on full feed 1.67 lbs. of the 

 special feed and 8.67 lbs. of corn meal per head daily. Lot 5 was fed Standard Stock 

 Food in addition to corn meal, consuming when on full feed 0.333 lb. of the former 

 and 10 lbs. of the latter per head daily. At the close of the test the pigs were sold in 

 C'hicago for $7.55 per 100 lbs. The following table shows the principal results 

 obtained: 



A nn-nge resulls of feeding various animal feeds to pigs in addition to corn. 



According to the authors, in the fattening of young pigs, a ration containing more 

 protein and ash than a corn ration gave better results than a ration of corn only. 

 Attention is called to the fact that this conclusion is based ui>on but one test and may 

 be modified by future experiments.

Experiments -with sugar as a feeding stuff, Alekan {Ann. Sci. Agron., 1901, 

 II, Xo. 1, pi>. 3S-4S). — In a i>aper presented at the International Congress of Agricul- 

 tural Experiment Stations, June, 1900, the author briefly reports the results of 

 experiments in which sugar formed part of the ration of horses. Rations contain- 

 ing sugar were ivgarded as especially satisfactory.

Cooperative experiments on the cost of egg production, H. H. Wing {Xen- 

 York Cornell Siu. Bui. 204, pp. 23-67). — The station cooperated with a number of 

 practical poultry feeders to secure information regarding the winter production of 

 eggs and the number of eggs produced per fowl under different systems of feeding, 

 care, and management. The flocks included ranged from 25 to 600 fowls, exclusive 

 of males. A summary of the tests follows: 



In the 17 weeks from December 1 to March 29 in 12 flocks, representing 8 owners 

 and 2, 100 fowls, the average daily production of eggs was 23.2 per 100 fowls. During 

 the same time the average food cost of 1 doz. eggs was 16.3 cts. The flocks that 

 laid most eggs during December and January laid most eggs also in March. 



The egg production of pullets (hatched in 1901) was notably in excess of that of 

 hens, particularly in the earlier periods, when the price of eggs was highest. The 

 average cost of feeding 100 hens for the 17 weeks was $32.43. The average excess of 

 production over cost of food for 17 weeks was $23.93 per 100 fowls.
