ANIMAL PRODUCTION. 1081 



fed corn meal and skim milk, 1:3, the other lots grain and skim milk, 1:6, the grain 

 ration consisting of corn, ext'ei)t in the ease of lots 4 and f), when corn meal and 

 wheat middlings, 4:1, were fed. Lots 3 and 5 received some bone meal in addition 

 to the other materials. All the lots were fed large amonnts from the start. The 

 cheapest gain, costing 4 cts. per pound, was made )>>■ lot :>, the most exjjensive, 

 costing 5.1 cts. per pound, by lot 5. In this and all the tests the live weight and 

 dressed weight were compared. 



"Asa result of 5 yeai-s' work it is found that most economic returns are secured 

 with skim milk when corn meal- is the grain used. The proportion of corn meal 

 to skim milk may be varied without apparently affecting results. In no case 

 shoihl the amount of skim milk fed be greater than the ))igs can (piickly and 

 easily consume." 



The value of corn, skim milk, and whey for fattening swine, A. M. 

 SouLE and J. R. Fain {Tenncxsee Slu. Bui., Vul. AT, No. J, pji. 16, J'kjs. G). — During 

 a period of tiO days the possibility of feeding pigs under local conditions was tested 

 with 3 lots of 3 and 1 lot of 2 grade animals. Lot 1 was fed corn meal mixed with 

 water, lot 2 the same grain mixed with skim nulk. Lot 3 was fed skim milk and 

 corn meal at first, and later whey, corn meal, and wheat meal. Lot 4 was fed skim 

 milk, cowpea hay, and corn meal. The attempt was made to feed lot 3 some sor- 

 ghum silage in addition to the ration noted, but as only .5 lbs. was eaten in 15 days, 

 it was discontinued. At the beginning of the test all the pigs weighed some 145 lbs. 

 each. In 60 days the average daily gain iter i)ig in the 4 lots was, res[)ectively, 1, 2.3, 

 2.2, and 2 lbs. The corresponding cost of a pound of gain was 3.9, 4.2, 3.4, 

 and 5.2 cts. Lot 1 required 4.6 lbs. of grain per pound of gain. Lot 2 required 2.2 

 lbs. of grain and 11.2 lbs. of skim milk. Similar values for lot 3 were 1.7 lbs. corn 

 meal, 0.4 lb. wheat meal, 2.5 lbs. skim milk, and 8.5 lbs. whey. Lot 4 required 2.9 

 lbs. of corn meal, 1 lb. chopped cowpea hay, and 12.5 lbs. of skim milk. 



As shown by slaughter tests the food had a marked effect on the carcass, the 

 dressed weight in the 4 lots being 73.6, 78.5, 76.2, 77.4 per cent, respectively, of the 

 live weight. Rating pork at 5.5 cts. per pound, the authors calculate that coi'u meal 

 was worth 66.7 cts. per bushel and skim milk 28.3 cts. per hundred pounds. Accord- 

 ing to the authors the exjieriments indicate that pig feeding can he made {)rotital)le 

 on Tennessee farms, that ordinarily enough feed is wasted on the farm to fatten a 

 number of pigs, " that intelligent methods of feeding bring a fair profit, and that the 

 farmer sliould ordinarily iinish his own animals, as they will then l)ring the highest 

 market prices." 



Market classes of horses, G. M. Rommkl {V. S. Depl. Agr., Btircax of .\rnmal 

 InduMrtj Bui. 37, pp. 32, ]iU. 12). — The condition of the horse market in recent years 

 and at the present time is sjxjken of. The author also discusses the general essentials 

 of market horses, paying special attention to the different classes. Of these the more 

 important are draft animals and harness and saddle horses. It is stated that the 

 bulletin consists cliiefly of information gathered from breeding establishments, horse 

 markets, and hunt cIuIjs. 



Report of manager of poultry department, W. R. CiK.vnAM ((hilorio Ayr. Col. 

 and Expl. Funn Itpt. luoi, pp. 1 12-124, .fig>^- 20). — Brief statements are made con- 

 cerning the j)oultry kept during the year at the Agricultural College, *he eggs pro- 

 duced, and the chickens hatched. Feeding tests are also reported. On an average 

 the eggs produced by 2 lots of 12 Barred Plymouth Rock hens during May, June, and 

 Jul)' cost 6.32 cts. per dozen; those produced by the same number of .\ndalusians, 

 5.38 cts. per dozen. In each case a cock was kept with the hens, and l)oth lots were 

 given the same care and were fed similar rations. 



Different grain rations were tested with chickens fed in coops for periods of 2 

 weeks. The following table sunnnarizes the results obtainetl. In the case of ration
