Tlic cfft'ct of tlic different fei'ds on tlie liriiiness of lanl was likewise studieil, the 

 results ))eing recorded in <let:iil. I'eaiuits fe<l until the pigs were slaughtered caused 

 very soft lard. Chufas liad nearly as i)ronounced an effect. The sui)i)lementary 

 feeding of any of the grains tested increased markedly the hardness of the lard, Imt 

 it is said that feeding grain exclusively for 26 to 35 days just before slaughtering failed 

 to make the flesh and lard as Arm as that of pigs which had never been fed peanuts. 

 WIk'u 20 or 25 per cent cotton-seed meal was fed in addition to corn meal the melting 

 point (»f lard was 3.4° F. higher than on corn meal alone. 



With several of the pigs the effect of cotton-seed meal and corn meal and of corn 

 meal alone on the weight of Ihe internal organs, the hlood, and tiie dressed carcass 

 was also studie<l. 



"The most significant differences attrihnlahle to the f Is aiv the greater weight 



of kidneys and heart of the pigs receiving the more nitrogenous ration, and the 

 greater weight of lungs (as in our former experiments) when the ration was highly 

 cai'lionaceons." 



Whole corn compared with corn meal for fattening pigs, W. A. 1Ii:ni:v ( Il'/.s- 

 coHxIn Sta. liijl. 190J, pp. 10-16). — Tsing younger pigs than in jirevious tests (E. S. 

 R., 13, p. 980) the relative value of whole corn and corn meal, each fed with an 

 equal quantity of wheat middlings, was studied. In the first trial, which was made 

 with 4 lots of 3 razorback or razorback crosses, weighing not far from 75 lbs. each, 

 2 lots on whole corn gained 234 and 189 lbs., respectively, in the 12 weeks of the 

 trial, consuming 4.44 and 5.94 lbs. of whole corn j^er pound of gain. The 2 lots on 

 C(jrn meal gained resjiectively 218 and 166 lbs., consuming 4.49 and 5.79 lbs. of corn 

 meal per pound of gain. 



The second trial covered 13 weeks and was made with 2 lots of 1 Berkshire and 2 

 Poland-China pigs each, weighing about 133 lbs. per head at the l)eginning of the trial. 

 On whole corn the total gain was 255 lbs., the corn eaten jjer poimd of gain being 

 5.59 lbs. On corn meal the total gain was 274 l)>s. and the amount eaten per pound 

 of gain 5.13 lbs. 



Summarizing the results of the tests at the station, which have extended over 7 

 years, the author states that a saving due to grinding has been observed in 9 cases, 

 the amount saved ranging from 3 to 17.6 per cent. In 3 cases a loss ranging from 1 

 to 9 per cent has been observed. No allowance has been made for the cost of grind- 

 ing, "the figures given being based entirely ujion the gain or loss incurred while 

 feeding." 



Results of an experiment to determine the comparative effect upon the 

 growth, development, and character of the carcass of pigs fed upon rations 

 of ground peas and corn meal, W. L. Caklyle and T. F. ]McConnkll ( Wisconmi 

 Sta. Rpt. 1902, pp. 17-3S, figs. 12) . — The comparative value of ground peas and corn 

 meal was studied in continuation of earlier work (E. S. R., 13, p. 979) with 2 lots, 

 each containing 7 pigs (Berkshire, Poland-China, razorback, and razorback crosses), 

 averaging about 68 lbs. in weight at the beginning of the trial. During the test, 

 which covered 28 weeks, 1 of the pigs fed ground peas died. Ivu'h of the grains 

 was made into a slop with water and fed ad libitum 3 times a day. The nutritive 

 ratio of the pea meal ration was 1:3.2 and that of the corn meal ration 1:9.8. On 

 the former the average daily gain per pig was 0.837 lb. and on the latter 0.540 lb., 

 the feed eaten per pound of gain being 4.95 lbs. and 6.06 lbs., respectively. In 

 connection with the test the different breeds were compared. The lowest daily gain 

 per* pig, 0.55 lb., was observed with the razorbacks, and the greatest gain, 0.75 lb., 

 with lot showing 0.75 Berkshire an<l 0.25 razorback blood. The latter pigs and 2 

 other razorback-Berkshire crosses required the smallest amount of feed per pound of 

 gain, namely, 5.2 lbs. The largest amount, 6.17 lbs., was re<iuired by the Poland- 

 Chinas. The pigs were slaughtered and the weight of the blood, loose fa(, and 

 internal organs recorded. The dressed weight was practically the same in both lots, 

 being about 77 per cent of the live weight.
