Feeding lambs, J. Wilson and G. F. Curtiss {Iowa Sta. Bui. 33, 

 pp. 527-565, Jigs. 18). — A feeding experiment was made with 5 yearling 

 sheep and 109 lambs, 10 of which were range lambs and the remainder 

 of the following breeds: Southdown, Shropshire, Oxford, Suffolk, Lin- 

 coln, Cots wold, Leicester, Dorset, and crossbred Shropshire on Merino. 

 The sheep were purchased in November. As soon as they arrived at 

 the station, they were all put on blue-grass pasture and in addition were 

 fed oats twice a day. The rams were castrated. The latter part of 

 November the lambs were divided into 10 lots of 10 each and 1 lot of 9, 

 each breed constituting one lot; and the 5 yearlings composed 1 lot. 

 Each lot was put into a shed facing south connected with a small yard. 

 They were given an abundance of bedding and supplied with salt. 



The experiment proper began January 1 and lasted 3 months. All 

 the lots were fed hay of various sorts, grain, and some roots. The hay 

 and grain were fed principally in the morning and at night and the roots 

 were fed at noon. The various grains were thoroughly mixed and fed 

 in a trough and the hay was fed in racks. 



During the preliminary period on pasture and for the first 10 days of 

 the experiment proper the grain ration consisted of bran, oats, and corn, 

 in the proportion of 1 : 1 : 4. The ration was then gradually changed to 

 bran, linseed meal, oats, and shelled corn, in the proportion of 1 : 2 : 8: 8. 

 This ration was continued until the close of the experiment, and the 

 animals were given all the food they would eat. The financial state- 

 ment is based on bran and oats at 40 cts., shelled corn at 28 1 cts., lin- 

 seed meal at 91) cts., hay at 28 cts. and turnips and mangel-wurzels at 

 5 cts. per 100 lbs. The details of the experiment are given in tabular 

 form. The results are summarized in the following table:
