568 EXPERIMENT STATION EECORD. [Vol.41 



Preliminary report is made of experiments by M. H. Fobrman witb Holsteln 

 and Jersey calves as to tbe necessary duration of slvlm milk feeding under 

 these circumstances. It is claimed tbat practically normal growth occurred 

 when the calves were fed liberally on skim milk, legume liay, and grain for only 

 GO days and then changed to a straight hay and grain ration. 



Sheep on irrigated farms in the Northwest, S. O. Jayne {U. S. Dept. Agr., 

 Farmers' Bid. 1051 {1919'), pp. 32, fl(js. 6).— About half this publication deals 

 with the general problems of sheep management on irrigated farms with special 

 reference to feeds and pasture, and summarizes the economic position of sheep 

 husbandry in irrigation agi'iculture. The rest consists of reports of a survey 

 made by the Office of Farm Management of 12 representative sheep farms in the 

 irrigated districts of Washington, Idaho, and Montana. The reports outline the 

 system of flock management on each farm and give notes on other live stock 

 raised, crops grown, pastures used, prices received for wool, etc. 



These farms " illustrate some of the varied conditions under which sheep are 

 being kept to good advantage on irrigated farms, and show that the business is 

 one that need not be confined to farms of any particular size or type or lo- 

 cality. . . . There are not many irrigated farms anywhere in the Northwest 

 on which small flocks of sheep could not be kept with profit, if given proper 

 care." 



Does it pay to feed corn to fattening lambs on pasture? J. W. Hammond 

 {Mo. Bui. Ohio Sta., 4 {1919), No. 7, pp. 228-231) .—Two sets of experiments are 

 reported, one at the Southeastern Test Farm at Carpenter, the other at 

 Wooster. The former consisted of tests during the summers of 1916 and 1917 

 in which a lot of lambs on blue grass pasture and another lot on a succession 

 of forage crops (rye, red clover, and rape) were given a full feed of corn. 

 Southdown X Merino lambs were used tlie first season and Merinos the second. 

 The lambs used in experiments 2 and 3, ircspectively, of a previous report (E. S. 

 R., 41, p. 177) constituted the check lots of the successive years. The feeding 

 of corn increased the gain on blue grass 11.5 per cent in 1916 and 35.5 per cent 

 in 1917, and on forage crops 12.6 and 21.1 per cent, respectively ; increased the 

 average dressing percentage in each case; and increased the market value per 

 hundred pounds. 



The experiments at Wooster were made in 1917 with 52-lb. grade Shropshire 

 and with 46-lb. Shropshire X Merino lambs on rape pasture. A lot of each was 

 given a full feed of corn, another a half feed, and a third no supplement. The 

 daily gains on rape alone averaged 0.28 lb. per head for the grades and 0.33 lb. 

 for the crossbreds. The corresponding gains on corn, half feed, were 0.37 

 and 0.34 lb., and on corn, full feed, 0.4 and 0.35 lb. There were practically no 

 differences in the finish of the several lots aor in the average dressing per- 

 centages. 



For each set of experiments computations are' presented showing the profits 

 or loss attending the feeding of corn of different prices to fattening lambs on 

 pasture. It is concluded with some reservations that the operation would be 

 profitable with corn at $1.12 a bushel but not at higher prices unless good pas- 

 ture were scarce. 



Feeding experiments [with hogs], J. M. Scott {Florida Sta. Rpt. 1918, pp. 

 21-23). — Three lots of 5 hogs each weighing about 90 to 95 lbs. per liead were 

 put on a 62-day feeding trial beginning December 4, 1917. The respective lots 

 were fed shelled corn alone, shelled corn and unhulled peanut oil feed (6.5: 1), 

 and shelled corn and velvet bean feed (5:1), with corresponding daily gains of 

 0.8, 0.61, and 0.58 lb. per head. Each lot also received 10 lbs. of green rape 

 daily. All of the carcasses were hard after 48 hours in the cooler, and the 

 peanut-fed lot was indistinguishable from the others.
