Cornparinj; tlio weight of tho livers wiUi the dressofl weight of the carcass wo find a 

 dirterence against tho corn-fed hog of over 19 per cent for the blood-fed and 16 poi 

 cent for the peas-fed hogs. • » » fhe kidneys follow the blood and liver in being 

 heavier with the first two lots of hogs than with the last lot. * • - 



There was nearly 2 i)or cent more fat in the kidneys of the corn-fed hogs than in 

 the kidneys of the other two lots. This shows that the fattening process reached even 

 the kidneys. 



Figuring with or without tho fat there was considerably more dry matter in the 

 kidneys of the first two lots [dried blood and pea meal] than the last lot [corn meal], 



Effects of rain-water, ivell-water, and hone meal on the growth of carcass 

 and strength of hones of pigs (pp. 13-15). — lu this experiment rations 

 consisting (1) of corn meal, rain-water (containing 6.44 grains of solids, 

 mostly carbonate of lime, per gallon), salt, and ground bone; (2) of 

 corn meal, rain-water, and salt; and (3) of corn meal, hard well-water 

 (containing 40.10 grains of solids, mostly carbonate of lime, per gallon), 

 and salt, were each fed to two Poland China pigs during 149 days. 

 The results of the trial, which are tabulated " are so irregular that they 

 throw doubts on any conclusions that may be drawn." 



It i.s interesting to note, however, that supplying well-water seemed to give no 

 advantage over rain-water ; indeed the results are against well-water in the amount 

 of gain made, the food required for 100 pounds of gain, and the breaking strength 

 of ))ODes. Feeding ground bone seems to have greatly strengthened the bones of the 

 pigs getting it. 



Bone meal and hardwood ashes rvith corn meal, for hogs (pp. 15-17). — 

 This is a detailed account of an experiment briefly reported in Bulletin 

 Ko, 25 of the station (See Experiment Station Kecord, Vol. II, p. 301). 



Conclusions dratcnfrom experiments on the effects of various food rations 

 on the carcasses of hogs (pp. 18, 19). — For a similar summary of four 

 years' experiments in pig feeding at the station see below, p. 438. 



Whole oats vs. ground oats for hogs (pp. 20-24). — An experiment with 

 four lots of three pigs each, in which rations consisting of one third 

 whole oats to two thirds corn meal and the reverse proportion, were 

 compared with rations consisting of one third ground oats to two thirds 

 corn meal and the reverse, the pigs being changed from the whole to the 

 ground oats and vice versa in alternate periods. The trial extended over 

 four 30-day periods. 



The detailed results are tabulated. In general, the results were best 

 with ground oats and in the proportion of about 1 part of oats to 2 

 parts of corn meal. 



Where the ration contained one third ground oats and two thirds corn meal, tho 

 average of four trials shows that only 403 pounds of feed were reijuircd for 100 

 jiounds of gain. This is the best average ever attain;;d by us in any feeding trial 

 with hogs as old as these [108 to 125 days at the beginning of the experiment], and 

 shows in a remarkable degree the value of tho oats when mixed with corn.
