of work previously noted (E. P. R., 23, p. 575), it has been found that a 7 per 

 cent difference in lamb crop in favor of pasture and shed management may be 

 secured over the old method of open range. 



Lamb feeding experiments, H. J. Gramlich {Nebraska Sta. Bui. 153 {1915), 

 pp. 5-26). — Five lots of 50 Western lambs each were fed 65 days with the results 

 shown in the following table : 



Summary of lainh-feeding experiments. 



A table showing the cost per 100 pounds of gain with corn and alfalfa hay at 

 varying prices is given. " With corn high and alfalfa cheap, the cheapest 

 gains can undoubtedly be made by feeding a medium corn ration and heavy 

 feed of alfalfa." The net profit realized on the 250 lambs was $214.99. 



Four lots of 7 native lambs each were fed 59 days, lot 1 receiving corn and 

 alfalfa hay, lot 2 corn, alfalfa hay, and corn silage, lot 3 ground corn and 

 ground alfalfa, and lot 4 corn, oil meal, and prairie hay. They made average 

 daily gains per head of 0.632, 0.523, 0.4S6, and 0.496 lb., costing 4.48, 5..56, 6.24, 

 and 6.96 cts. per pound of gain, for the respective lots. Lot 1 required 3.48 lbs. 

 of corn and 1.52 lbs. of alfalfa, lot 2, 4.09 lbs. of corn, 1.96 lbs. of alfalfa, and 

 1.18 lbs. of silage, lot 3, 4.25 lbs. of corn and 2.42 lbs. of alfalfa, and lot 4, 3.58 

 lbs. of corn, 1.13 lbs. of prairie hay, and 2.04 lbs. of oil meal per pound of gain. 



Two lots of lambs, lot' 1 being western lambs fed in the open lot, and lot 2 

 native lambs shed-fed, both lots receiving shelled corn and alfalfa hay, made 

 average daily gains per head of 0.393 and 0.632 lb., consuming 3.67 lbs. of corn 

 and 2.38 lbs. of alfalfa, and 3.48 lbs. of corn and 1.52 lbs. of alfalfa per pound 

 of gain, and costing 5.11 and 4.48 cts. per pound of gain for the respective lota. 



In a similar comparison, except that shelled corn, alfalfa, and silage were 

 fed, the lambs made average daily gains per head of 0.398 and 0.523 lb., con- 

 suming 3.66 lbs. of corn, 2.05 lbs. of alfalfa, and 1.21 lbs, of silage, and 4.09 lbs. 

 of corn, 1.96 lbs. of alfalfa, and 1.18 lbs. of silage, per pound of gain, and costing 

 5.15 and 5.56 cts. per pound of gain for the respective lots. When the feeds 

 were ground corn and ground alfalfa, the lambs made average daily gains per 

 head of 0.371 and 0.486 lb., consuming 4.23 lbs. of corn and 2.27 lbs. of alfalfa, 

 and 4.25 lbs. of corn and 2.42 lbs. of alfalfa per pound of gain, and costing 6.12 

 and 6.24 cts. per pound of gain for the respective lots. 



Substitutes for corn in winter rations for fattening swine, B. E. Cae- 

 MicHAEL (Mo. Bill. Oliio Sta., 1 {1916), No. 1, pp. 3-9, figs. 10). — A popular dis- 

 cussion of results previously noted (E. S. R., 21, p. 173; 31, p. 868). 



Malnutrition in hogs, D. J. Healy and E. J. Gott {Kentucky Sta. Circ. 4 

 {1915), pp. 3-7, figs. 2). — An account of a feeding trial with 10 pigs infested 

 with worms 'and suffering from malnutrition, which by proper care and feed 

 were brought around to a thrifty condition in 54 days and made to bring a 

 profit of $7.88 over the cost of feed, medicine, and care.
