 makes the living animal so attractive to the eyeofthe breeder, is a certain source of 

 waste and loss to the butcher who buys the animal for slaughter and the profits of

Pig feeding, J. L. Hills ( Vermont 8ta. Jx'pt. 189 6-* 97, pp. 34.-43). — In 

 continuation of work previously reported (E. S. if., 8, p. 1012) a test was 

 made, with 12 pigs to compare the feeding value of corn meal and whole 

 corn and skim milk, and corn meal with whey and wheat bran, and to 

 learn whether skim milk is most profitably fed in large or small quan- 

 tities. The test was divided into I periods of 45, 43, 36, and 02 days 

 each. The pigs were divided into 1 lots of 3 each. Lot 1 was fed qt. 

 •of skim milk and 12 oz. of corn meal daily; lot 2 was fed the same 

 quantity of skim milk and 12 oz. of shelled corn; lot 3 was fed 1 oz. of 

 corn meal to a quart of skim milk, the amount being increased to 12 

 qt. of milk and 24 oz. of corn meal; lot 4 was fed 12 oz. of bran with 

 whey in increasing amounts until 12 qt. was fed daily. During part 

 of the test lots 3 and 4 were fed an additional quantity of corn meal, 

 or corn meal and bran, 1 : 1. 



The financial statemenl is based on skim milk at 15 cts. and whey at 

 9 cts. per 100 lbs. and corn meal and bran at $14 and $12 per ton, 

 respectively. The total cost of the food eaten was $112.74, leaving as 

 a profit but $2.55. 



The foods consumed and the gains made by each pig are given in 

 tabular form. The pigs were slaughtered and sold for l.\ cts. per 

 pound, dressed weight. The weights and percentage of shrinkage are 

 recorded. The average results of the test are shown in the following-

The author's conclusions are as follows: 



"(1) Corn meal proved superior to shelled corn. It is doubtful, however, whether 

 the gain was equal to the extra cost of grinding. 



"(2) Whey in large quantities with bran proved a more economical teed than 

 skim milk in large quantifies with corn meal, but no more so than skim milk fed in 

 small quantities with corn meal. 



"(3) The economy of production was decidedly in favor of small rather than large 

 quantities of skim milk. 



"(4) Profits tinned to losses as the average pig grew beyond 150 lbs., because of 

 ow prices for pork and illiberal feeding during middle life. 



"(}>) Subtracting the cost of grain from the total receipts, allowing manure to
