confirms the result of a previous experiment witli rape, and goes to show tliat a

 proportion of, green feed to meal is i)ractically the same as the proportion of roots 

 to meal which we have usimI with good results, it seems safe t<j assume that the use 

 of eciual weights of succulent food and meal tends to produce bacon of firm ([uality. 

 The time recpiired to attend to the outside hogs was just about lialf of that required

Feeding experiments, H. E. Stockbkiuge {FIvrida. >Sf((. Rpt. I'.i0l,pi>. l>!-22, 

 jU. '). — Statements an' made concerning steer-feeding tests not yet reixtrted in full. 

 The author also briefly reports a test of the comparative gains made by 5 ra/.firback 

 and (> I^uroc Jersey pigs, fed alike from birth until they were 14 months old. At 

 this time the average live weight of the razorbacks was 214.4 lbs., and the Duroc 

 Jersey 216.3 lbs.; the average dressed weight of the former 170.8, of the latter 1()4.2 

 lbs. "The native razorback animal produced on an average from the food con- 

 sumed 6.4 lbs. more of marketable meat than his full-blooded rival, quite contrary 

 to usual expectation." In discussing the comparative merits of native and blooded 

 stock, the author calls attention to the fact that the l>looded pigs possess advantages, 

 especially in the matter of early maturity, which make them especially valuable for 

 crossing with native stock. '' It is an un(iuestioned fact, however, that the meat of 

 the native is of incomparably superior quality, and that when properly handled and 

 given suitable and adequate feed and attention the native crowds his blooded rival 

 in the race, and can be made as profitable as he is hardy." 



Tankage as a food for pigs, C. S. Plumb and H. E. Van Norman {Indiana Sfa. 

 Bui. 90, pp. J05-216). — Using 4 lots of 4 pigs each, weighing 58 lbs. on an average, 

 the authors studied the value of tankage as a part of a ration. The tankage used 

 was of the sort known as "crushed," and is generally sold as a fertilizer. Like all 

 such material, it contained a high percentage of nitrogen and phosphorit- acid. 

 Lots 1 and 4 were fed grain and tankage 10 : 1, the grain ration of the former consist- 

 ing of corn meal and of the latter of corn meal and shorts 1:1. Lot 2 was fed corn 

 meal and tankage 5:1, and lot 3 corn meal only. The feed was mixed with water to 

 a thin slop. In the 127 days covered by the test the average daily gain of the 4 lots 

 was 1.16, 1.23, 0.67, and 1.14 lbs. per head. The largest amount of grain, 15.75 lbs. 

 per day, was consumed by lot 4; the smallest, 14 lbs. by lot 3; lots 1, 2, and 4 con- 

 suming, respectively, 1.54, 2.98, and 1.57 lbs. of tankage daily. The cost of feed per 

 pound of gain in the 4 lots was 3.8, 4, 5.2, and 3.6 cts., respectively. At the close of 

 the test 2 pigs in each lot were slaughtered and the organs, etc., examined. The 

 conclusion was drawn that as regards the carcass no differences were observed which 

 could be attributed to the rations fed. According to the authors the condition of 

 the pigs during the test was of much interest. The lots fed tankage had noticea1)ly 

 silkier hair, and the appearance of the skin was fresher and mellowi-r than that of 

 the corn-fed lot. In marked contrast to the others the corn-fed pigs did not eat with 

 relish after the experiment was well started. That this was due to the corn ration 

 was shown by a supplementary feeding test in which the 2 pigs remaining in lot 3 

 (the corn-fed lot) were put upon a ration of corn meal and tankage 5:1, and fed for 

 a period of 49 days. After the tankage was added to the rations, the authors state 

 that the condition of the pigs was markedly improved and the 2 jiigs gained on an 

 average 1.79 and 1.3 l])s. per head daily. 



Separator skimmed milk as food for pigs, L. A. Clinton {Sew York Cariiell 

 Sta. Hill. i:ni. i>i>. l.!7-l-'>i'>). — From 1S9S to 1901 the comparative merits of different 

 j)roportions of grain and skim milk for iiroducing pork economically were studied. 

 The first test was preceded by a preliminary i)eriod of 6 days' duration, durhig which
