ANIMAL PRODUCTION. 73 



The story of the Herefords, A. H. Sandeiss {Chicago: The Breeder's Gazette, 

 1914, PP- 1087, pi. 1, figs. 278). — ^An account of the origin and development of 

 tlie breed in Herefordsliire, and a sketch of its early introduction into thp 

 United States and Canada and subsequent rise to popularity in the western 

 cattle trade, \A'ith sundry notes on the niauagemeut of breeding herds. 



Sheep breeding, F. W. Wilson {Arizona Sta. Rpt. 19U, pp. 352-356, 358).— 

 A brief report is given of the sheep breeding experiments wbich have been in 

 progress since 1906. In these experiments the Tunis, Shropshire, Hampshire, 

 Rambouillet, Oxford, Dorset, Navajo, and native breeds have been used in 

 various combinations. It is said that the first generation of Tunis and native 

 half-blood is the most promising cross to date. 



A table is given showing the average weights of the sheep at birth, six 

 months, and one year, with the weight of the fleece for all crosses num- 

 bering six or more individuals. A total of 448,223 lbs. of wool shipped in Feb- 

 ruary and March weighed 452,852 lbs. when sold in the Boston market, due 

 to the gain in moisture. 



Are sheep profitable in Maine? 0. D. Woods {Maine Sta. Bui. 236 {1915), pp. 

 59-61). — This is a preliminary report of an experiment undertaken at High- 

 moor Farm for the purpose of ascertaining whether or not hay and pasturage 

 can be profitably marketed through sheep under Maine conditions. 



Production and price of wool, E. Payen {Econ. Franc., 43 {1915), I, No. 3, 

 pp. 70-72). — This is a statistical review of the wool production of the world. 



The value of distillers' dried grains in swine feeding operations, E. S. 

 Good and W. V. Smith {Kentucky Sta. Bui. 190 {1915), pp. 5-18).— The object 

 of this experiment was to determine the value of distillers' dried grains in 

 swine-feeding operations as a supplement to pasture, to com meal and pasture, 

 and to corn meal fed in the dry lot. 



Four lots of from 10 to 15 shoats, weighing approximately 68 lbs., were fed 

 73 days as follows: Lot 1, distillers' dried grains and pasture (oats, rape, and 

 pigweed) ; lot 2, corn meal and pasture; lot 3, corn meal and distillers' dried 

 grains 5 : 1, and pasture ; and lot 4, corn meal and distillers' dried grains 5 : 1 

 in dry lot. They made average daily gains of 0.456, 0.931, 1.027, and 0.SS3 lbs. 

 per pig, consuming 3.68, 3.44, 3, and 4.44 lbs. grain per pound of gain, at a cost 

 of 4.97, 4.95, 4.27, and 6.32 cts. per pound of gain (corn meal costing $28.78 

 per ton, distillers' dried grains $27 per ton) for the respective lots. Figuring 

 that 85 per cent of the fertilizing constituents of the different feeds passed 

 through the animals, it is estimated that the total value of the manure was 

 $14.72, $8.99, $12.24, and $10.40 for the respective lots, or about 41 cts. for each 

 100 lbs. of grain fed. 



The pigs did not relish distillers' dried grains alone, as they ate on the aver- 

 age only 1.68 lbs. daily, although given all they would eat. As a grain supple- 

 ment to pasture, however, distillers' dried grains proved of value in this experi- 

 ment as a gain of nearly 0.5 lb. per head per day was obtained on an other- 

 wise unprofitable pasture. 



The value of wheat as a feed for swine, E. S. Good and W, V. Smith {Ken- 

 tucky Sta. Bui. 190 {1915), pp. 19-27). — The object of this experiment was to 

 determine the value of wheat alone and with a nitrogenous supplement as a 

 feed for swine, and also to determine the form in which wheat can be fed to the 

 best advantage. 



Four lots of about 10 shoats each, weighing approximately 105 lbs., were fed 

 62 days as follows: Lot 1, whole wheat soaked; lot 2, ground wheat dry; lot 3, 

 ground wheat soaked; and lot 4, ground wheat and tankage 14: 1. They made 

 1.5, 1.72, 1.6S, and 1.78 lbs. average daily gain per pig, consuming 4.26, 3.74, 3.82,
