EXPERIMENT KTATION RECORD. 



Siiuilur tests uuide elsewhere are discussed aud a summary is given 

 of the results of 31 experiments made at the station and elsewhere with 

 pigs of various weights fed a ration of skim milk with corn meal or 

 corn meal and middlings. These indicate that "the older and heavier 

 pigs grow, the greater the amount of feed it takes to maintain them and 

 the less i)roflt in keeping them." 



Gains of pigs and calves compared (pj). 54-50). — A feeding test with 

 2 calves was made at the same time as the preceding test and under 

 similar conditions. One was a pure-bred llolstein bull calf, and the 

 other a Brown Swiss heifer calf, and both were 11 weeks old at the 

 beginning of the test. The test began April 14 and lasted 17 weeks. 

 For about a mouth the calves were fed separator skim milk. They were 

 then given in addition ck)ver hay and a grain ration consisting of linseed 

 meal, oats, and bran, 1:2:2. From the latter part of June until the 

 close of the test calf Xo. 1 was fed whole milk instead of skim milk. 

 The amounts of food consumed and gains made by each calf are 

 recorded in tabular form. The gains made by the calves and by the 

 pigs in the previons test are compared in the following table:

Though the pigs and calves were fed under similar conditions their 

 gains were very different. The pigs reijuired a much larger proi)ortion 

 of grain to skim milk than the calves. 



Pig feeding, J. L. IIills ( Vermont tSta. B2)f. ISDo^pp. .57-05). — Experi- 

 ments in continuation of previous work of the station (E. S. R., 8, p. 78) 

 were made with pigs to test the value of corn meal vs. whole corn, skim 

 milk vs. buttermilk, and wet corn meal vs. dry corn meal. 



The first two questions were studied with 10 pigs about 6 weeks old 

 at the beginning of the trial. jSTos. 1 to 5 were Yorkshire-Chester 

 Whites and Nos. 6 to 10 Berkshires. l!^os. 1, 5, 6, 7, and 10 were fed 

 a basal ration of qt. of separator skim milk and 0.75 lb. of corn 

 meal per head daily. After a short time corn meal and bran 1: 1, in 

 increasing amounts, was added to the basal ration until the pigs weighed 

 about 200 lbs.; the bran was then omitted. Xos. 2, 8, and 9 received 

 the same basal ration and in addition whole corn and bran, in increasing 

 amounts, until the pigs weighed about 200 lbs., when the bran was 

 omitted. Kos. 3 and 4 were fed the same ration as Nos. 1, 5, G, 7, and 

 10, except that 7 qt. of buttermilk was fed in place of qt. of skim 

 milk. The test began June 22 and ended December 20. It was divided 

 into 5 periods of from IS to G2 days' duration. The financial statement
