EXPERIMENT STATION RECORD. 



lbs. Lot 1 required 5.59 lli8. of corn per pound of gain, while l(jt 2 required 4.79 lbs. 

 The results have varied in different years, therefore the authoi's believe that the tests 

 must be continued before definite conclusions can be drawn. 



Feeding- value of rape for gro-wing- pigs, W. L. Carlyle ( Wisconmi Sta. Rpt. 

 1900, pp. 25-27). — The feeding value of rape alone was tested with 30 pigs averaging 

 6 months old at the beginning of the test. For 2 weeks they were pastured on about 

 4 acres of rape. It was eaten readily and with no bad effects. During the time the 

 pigs lost a total of 60 lbs. 



"The 7'esult» of this experiment would indi(;ate that a ration of rape alone fed to 

 pigs for a peri-^d of 2 weeks was not sufficient to supply the food necessary for their 

 support. It is quite possible, however, that it may have a much higher feeding value 

 for pigs at this age than when fed in ccjnjunction with grain feed."

DAIRY FARMING— DAIEYING. 



On the economy of heavy grain feeding of dairy cows, F. \V. Woll and 

 W. L. Carlyle {Wisconsin Sta. Rpt. 1900, pj). 37-61). — A feeding experiment com- 

 paring medium and large quantities of grain, conducted on the same general plan as 

 earlier work (E. S. R., 12, p. 81), is reported. The experiment included 2 lots of 8 

 cows each and covered 3 periods of 4 weeks each. A medium or normal grain 

 ration, "the amount of grain which, according to careful observations and trials, was 

 required by each animal for maintaining a good flow' <jf milk and a constant live 

 weight," was fed to the cows in lot A during the first and third periods and to the 

 cows in lot B during all 3 periods. The quantity of grain in this ration averaged 

 about 8 lbs. A heavy grain ration, which was I2 times the normal ration, was fed to 

 lot A during the second iieriod. The grain consisted of wheat bran, ground oata 

 ground corn, and old-process oil meal. Hay and silage were fed in addition 

 Analyses of the feeding stuffs and the nutrients of the rations are given in tables. 

 Some of the data are summarized in the following table: 



Results of feeding different amounts of grain to milch cows. 



The results are discussed at some length. The production of milk and butter per 

 unit of dry matter consumed decreased during the heavy grain feeding. The after 

 effects were unfavorable to heavy grain feeding. "The results of the experiments in 

 this line conducted by us during the last two years lead to the general conclusion that 

 it does not pay to feed dairy cows more than a medium amount of grain feed, which 

 may be placed at about 8 lbs. per head daily, except in case of cows of marked dairy 

 tendencies that respond to heavy grain feeding by an increased production of milk 

 and fat rather than bv a gain in live weight."
