CORX HEARTS VERSUS COWPEA MEAL VERSUS CORN MEAL. 



For a period of seven weeks, in addition to a week of 

 preliniinar}' feeding, in Januai*y and February, 1899, 

 these food stuffs were comfpared, each being fed in con- 

 nection with an equal weight of rice bran obtained from 

 Ernst & Co., New Orleans. There were three lots of re- 

 cently weaned pigs, each lot containing three pigs. All 

 the pigs except one were from the same litter, and were 

 crossbred Berkshire — Poland Chinas. 



The unusually cold weather of this time, inadequate 

 pig pens, and the rather unpalatable natui-e of all the 

 rations, due to the admixture of rice bran, made the 

 rates of growth slow and unsatisfactory.

The ration containing com meal was the most effect- 

 ive one, probably because of its greater palatability, 

 hence the larger amount consumed. 



According to partial analyses made in the chemical 

 laboratory here the rice bran used contained 9 per cent, 

 of protein, and the com hearts 8.9 per cent, of protein. 



Rice polish as a food for pigs. 

 The high price of corn during 1902 made it desirable 

 to look for some substitute in addition to such materials 

 as can be grown on the farm. Hence rice polish was em- 

 ployed in a number of experiments and was tested in 

 comparison with corn meal. In different experiments 

 these two foods were used alone or each combined with 

 corresponding proportions of other foods. Each lot con-
