EXPERIMENT STATION BULLETINS. 



119 



Considering first the feeding period as a whole, and computing the amounts of the 

 several feeding stuffs required to produce a hundred pounds of gain with each lot of 

 steers we have the following table: 



Feeds required to produce 100 lbs. of gain. 



In lot 1 the steers ate 1,361 pounds of pulp for each hundred pounds added to their 

 weight. It required, however, 1(56 pounds less ha}'; 22.2 pounds less bran, 201.4 pounds 

 less corn meal and 18.5 pounds less oats for a hundred pounds of gain than were required 

 of these materials for an equal gain with the steers having no pulp. Without going 

 into the question as to whether there was a profit in the feeding, a matter which depends 

 on the relation between the prices of beef and the feeding stuffs mentioned, it is taught 

 by the test that a ton of pulp at the rate just computed is worth 244 pounds of hay, 

 32.6 pounds of wheat bran, 296 pounds of corn meal and 27.2 pounds of oats so far as 

 efficiency in producing gains is concerned. 



After March 18 the weather turned warm and the steers without succulent feed 

 stopped gaining. If for this reason we conclude the experiment on March 18, we find 

 the gains of lot 2 to be 1,160 pounds as before, while the gains of lot 1 are 1,419 pounds 

 only. Up to that date lot 1 had eaten 18,950 pounds of pulp, but had also not required 

 as much hay and grain, the difference being 140 pounds of hay, 14 pounds of bran, 163 

 pounds of corn meal, 63 pounds of oats. Estimating as before, the feeds required to pro- 

 duce a hundred pounds of gain and computing from the data thus given the estimated 

 value of a ton of pulp in terms of the other foods we find one ton of pulp to produce 

 as much gain as 153.6 pounds of mint hay, 19.7 pounds of bran, 181.2 pounds of corn 

 meal, and 21.4 pounds of oats. These figures are less than when the whole period is 

 considered because the lot having no pulp gained in this case up to the close of the 

 period, while if we carry the experiment to March 25 the lot without succulent food 

 made no gains during the last week, although they kept on eating. The former figures, 

 however, are just, because the better appetite of the lot receiving pulp is clearly due to 

 the succulent feed. 



Up to March 4 both lots received the same quantity of hay and grain, the pulp being 

 fed extra. The difference in gains for the six weeks was 280 pounds, the pulp consumed 

 meanwhile being six tons, 1,775 pounds. 



FEEDING EXPERIMENT WITH DAIRY COWS. 



This experiment was conducted during the winter of 1898-1899. Eight cows, selected 

 from the grade dairy herd, Avere set aside for the test. The history of the cows for the 

 year preceding had been carefully kept as to yields of milk and butter fat and it was 

 therefore easy to find two groups of four cows each, well matched as to milk giving 

 capacity and relation to date of birth of last calf. 



The experiment began on December 28, 1898, the first week on the various feeds being 

 considered a preliminary period only, with results not included in the weights used in 

 making up the final results. 



The cows had been fed corn stover, hay, and a grain feed composed of bran and corn 

 meal, up to the time of the beginning of the experiment. Nearly all the cows had calved 

 within the five weeks preceding that date and all of them after the middle of October,
