of gain. The nine larabs in lot 2 were fed mixed hay and a mixture of barley 

 and bran (3:1). They made an average daily gain of 0.274 lb. per head- 

 at a feed cost of 8.5 cts. per pound of gain. The nine lambs in lot 3 were fed 

 mixed hay and a mixture of barley and linseed cake (3: 1). They gained an 

 average of 0.318 lb. per head da:ly at a feed cost of 8.71 cts. per pound of gain. 

 All the lambs received alfalfa hay during the last eight days of the test. 

 The grain mixtures were fed either ground or rolled. The larabs were 

 bought at 5 cts. per pound and sold for 6 cts. Each lot returned a profit, the 

 average for the three lots being 41 cts. per head. The charges per ton for 

 feeds in this experiment were hay $8, barley $24, bran $20, linseed cake $42, 

 and field peas $30. 



Suggestions are given for feetliug range lambs. 

 [Live-stock experiments] {New Mexico Sta. Rpt. 1916), pp. 51-55). — In an 

 experiment with four lots of seven pigs each in which lot 1 was fed all the 

 concentrates the pigs would eat within a reasonable time, lots 2 and 4 a con- 

 centrate ration at the rate of 2 lbs. per 100 lbs. live weight, and lot 3 1 lb. of a 

 concentrate and 8 lbs. of skim milk per 100 lbs., all of the lots having access 

 to good alfalfa pasture, the results were favorable to lots 2 and 4. However, 

 these pigs required an additional feeding period on a full ration to fit them 

 for market. 



In a test with two lots of 16 pigs each on alfalfa hay. one lot fed a full 

 ration of ground milo maize and a small quantity of skim milk was ready 

 for market 30 days earlier than the other lot which received a limitetl amount 

 of these supplements. In another test with pigs on alfalfa hay, one lot was fed a 

 mixture of milo maize and mesquite beans (2: 1), and the other lot had a full 

 ration of ground milo maize. The results indicate that with pork at 10 cts. 

 per pound, milo maize $1.50 per 100 lbs., and alfalfa hay 50 cts. per 100 lbs., 

 mesquite beans are worth $1.30 per 100 lbs. Some difficulty was experienced 

 In getting the beans properly ground for the pigs. This was best accomplished 

 by grinding the beans and the grain together in the proportions wanted. 



Data from feeding experiments at the Tucumcari dry-land substation indicate 

 that good results may be obtained in feeding range steers wholly on dry-land 

 crops. 



[Grazing experiments with pigs] (Idaho Sta. Bui. 92 (.1916), pp. 46, 47, 5i, 

 54, fit). I). — In te.srs at the Caldwell sub.station, reported by O. D. Center and 

 C. B. Hampson, three sows and 19 pigs were placed on 1 acre of alfalfa pasture 

 on May 18, 1915. On June 5 three sows and 14 pigs were added to the lot. 

 This drove was insufficient to keep the alfalfa pasture closely graze<l. and on 

 June 27 588 lbs. of cured alfalfa hay was harvested from the acre. The animals 

 were fed 25 lbs. of barley and 140 lbs. of skim milk daily. By August 11 

 these sows and pigs had gained 1,211 lbs. The pigs were then grazed on 1 

 acre of peas for 19 days, receiving in addition 11 lbs. of soaked barley and 20 

 lbs. of skim milk daily, and gained 155 lbs. on this acre. On August 30 they 

 wore turned on a second acre of peas and grazed for 13 days, and on Septem- 

 ber 11 on an acre of peas and wheat in combination for 17 days. The barley 

 and skim milk were continued in the same quantity. The pigs gaine<l 429 

 and 447 lbs. on these acres, respectively. 



At the Gooding substation, in work rei>orted by J. S. Welch, 21 young pigs 

 on one-half acre of alfalfa, supplemented by 3.2S4 lbs. of grain and 1,878 lbs. 

 of skim milk, made a gain of 1,362 lbs. in 131 days. In hogging off experiments, 

 five pigs grazed on 0.238 acre of peas for 27 days and produced gains at the 

 rate of 496 lbs. per acre. On a plat of 0113 acre of peas and wheat five pigs 

 grazed for 39 days, making gains at the rate of 565 lbs. per acre. On 0.216
