EXPERIMENT STATION RECORD. 



All the lots were given the same amounts of corn fodder and corn on 

 the ear in addition to the linseed meal. The amount of meal fed was 

 gradually increased until the yearlings were fed 4 lbs. per day aud the 

 other cattle 5 lbs. The composition of the old and new-process linseed 

 meal, the amounts of food consumed, and the gains made are given in 

 tabular form. The average daily gain of all the cattle was 1.39 lbs. 

 The total gain on old-process meal was 697 lbs., and on new-process 

 meal 783 lbs. 



" The health of all the cattle was good during the experiment. The pregnant cows 

 were not injured in any perceptible manner by eating either of the meals. From 

 indications had in this trial, new-process oil meal is as safe a by-product to feed 

 with other fodders as old-process oil meal. 



"The analyses of the two meals are substantially alike in protein, the old process 

 being richer in fat." 



Report upon the value of a new corn product, H. J. Patter 



SON (Maryland Sta. Bui. 43, pp. 105-185). — In the construction of war 

 vessels it is proposed to use corn pith as a packing between the inner and 

 outer shells. In preparing the pith for this purpose the blades and husks 

 are removed from the stalks and the stalks cut up into small pieces. 

 The pith is then removed, and the remainder of the stalk is ground up 

 into meal, "which in general appearance resembles coarse bran, dried 

 malt sprouts, or brewers 1 grain. This ground material is termed ' the 

 new corn product' in the following experiments." 



A number of experiments were made with 4 steers to determine the 

 digestibility of the new corn product as compared with shredded corn 

 fodder, fodder ground fine like the new corn product, wheat bran aud 

 a ration of equal parts of shredded corn fodder aud wheat bran, to 

 test the digestibility of the new corn product when fed wet and when 

 fed steamed, and to compare the digestibility of fattening rations con- 

 taining the new corn product and corn blades. The value of the new 

 corn product for producing fat was also tested. The digestion experi- 

 ments were carried on by the methods usually followed at the station. 

 After a preliminary period of 6 to 18 days the digestion experiment 

 lasted G or 7 days in each case. 



The steers were kept in well ventilated stalls. The bedding con- 

 sisted of excelsior covered with burlap. Analyses are given of the 

 feeding stuffs used. Several are quoted in the following table:
