Two lots of pigs about 8 weeks old were fed for 165 days to compare 

 separator skim milk with a (juantity of green clover furnishing 

 approximately the same amount of protein. Both lots had a basal 

 ration of corn and cowpea meal, linseed and gluten meal, 8:1:1. The 

 average daily gain per pig in the lot fed skim milk was 1.26 lbs., and 

 in the lot on clover, 0.6 lb., the cost of a pound of gain in the 2 cases 

 being 4.09 and 3.7 cts., respectively. The pigs were slaughtered at 

 the close of the test, the heaviest weighing over 200 lbs. dressed. On 

 the basis of his results the author calculates that green clover is worth 

 $2 per ton, and separator skim milk 11 cts. per hundredweight. 



Separator skim milk was compared with gluten and linseed meal for 

 balancing a grain ration, using 2 lots of 6 pigs each. Both lots were 

 fed a basal ration of homin}- chop and ground-corn shives during the 

 test which covered 121 days. The average daily gain of the pigs fed 

 the ration containing skim milk was 1.54 lbs., and of the pigs fed the 

 ration containing gluten and linseed meal, 1.12 lbs. The cost of a 

 pound of gain in the 2 cases was estimated at 3.5 and 2.51 cts., 

 respectively. 



Four tests are reported with young pigs weighing from 36 to 61 

 lbs. each on the value of ground -corn shives, /. e. "new corn product." 

 This material was fed as a partial substitute for hominy chop in the 

 first test, as a substitute for part of the mixed-grain ration in the 

 second test, as an addition to grain and skim milk in the third test, and 

 in the fourth test as a partial substitute for hominy chop, with linseed 

 meal and gluten meal during the last 3 months of a 5 months' trial. 

 Skim milk formed part of the ration in every case. In the tirst of 

 these tests the average daily gain per pig on the ration with corn 

 shives was 1.37 lbs.; on the ration without corn shives, 1.13 lbs. The 

 author calculates that the ground-corn shives were worth from $3.10 

 to $6.58 per ton, as shown by the returns in pork. The cost of this 

 material is stated to be $11 per ton. In the second test the average 

 daily gain per pig on the ration containing corn shives was 1.3 lbs. ; on 

 the ration without corn shives, 1.63 lbs.; the cost of a pound of gain 

 in the 2 cases being 2.96 and 2.57 cts. In the third test the average 

 daily gain per pig of the lot fed the ration without corn shives was 

 0.81 lb.; the cost of a pound of gain, 3.21 cts. The average daily 

 gain per pig in the lots fed corn shives varied from 0.87 to 0.94 lb. 

 and the cost of a pound of gain from 3.26 to 3.36 cts., the largest 

 gain but at the greatest cost being made on the ration containing the 

 least amount of corn shives. 



In the foui-th trial the average daily gain per pig in the 2 lots fed a 

 ration with linseed meal during the first period was 0.99 and 0.98 lb., 

 respectively, the cost of a pound of gain being 2.7 cts. The average 

 daih' gain of the 2 lots fed during the same time a ration with gluten 

 meal was 0.8 and 0.85 lb., respectively, the cost of a pound of gain
