770 EXPERIMENT STATION RECORD. [Vol. 37 



to determine whether a home-grown product, crushed oats, could be profitably 

 substituted for these imported feeds. The meal used was extracted with 

 chemical solvents and contained less oil than the cake which was extracted 

 under pressure. 



Thirty-two crossbred bullocks in lots of 8 each were fed for 84 days, divided 

 into periods of 28 days each. Turnips and straw were used as roughage. In 

 addition, lot 1 received linseed cake and crushed oats; lot 2 peanut cake and 

 crushed oats ; lot 3 palm kernel meal, crushed oats, and a small portion of locust 

 bean meal to induce the animals to eat the ration ; and lot 4 crushed oats. The 

 manurial value was deducted from the cost of the feed in each lot. On linseed 

 cake bullocks made an average gain of 2.31 lbs. daily, on peanut cake 1.99 lbs., 

 on palm kernel meal 2.15 lbs., and on oats alone 1.98 lbs. The net cost of gain 

 per hundredweight was for lot 1, 48s. ($11.66) ; lot 2, 46s. 3d.; lot 3, 51s.; and 

 lot 4, 50s. 



Peanut cake gave the best monetary retarna and was eaten readily. Crushed 

 oats alone, while costing more than the other feeds, was considered a satis- 

 factory concentrate with turnips and straw.

Live stock of the farm. — IV, Sheep, edited by C. B. Jones (London: The 

 Oresham Publishing Co., 1915, vol. 4, pp. X+252, pis. S8, figs. i8).— Chapter 

 1 deals with sheep farming in the British Isles, the development and distribu- 

 tion of breeds, and statistics. Chapter 2, prepared by various authors, gives 

 a description of the different breeds. Chapters 3, 4, and 5 are devoted respec- 

 tively to profitable sheep farming, general management and feeding, and dis- 

 eases. 



Sheep production, P. V. GabcU {Bol. ilin. Agr. [Argentina'\, 20 (1916), N: 

 5-6, pp. .^91-462, figs. S2). — A statistical discussion of the production and ex- 

 portation of sheep from Argentina from 1S95 to 1915. 



The number of sheep in the country has greatly decreased in this period, 

 especially among the lower grades. The quality of the animals has improved, 

 however, both as to wool and meat. The average weight of carcasses exported 

 from 1896 to 1915 shows a gradual increase from about 23 to above 27 kg. (50.6 

 to 59.4 lbs.). 



Sheep and wool for farmers. Crossbreeding experiments, J. W. Mathews 

 (Agr. Qaz. N. S. Wales. 27 (1916), Nos. 5, pp. S25-SS4, figs. 6; 6, pp. 897-407, 

 fig. 1). — This experiment, which is being continued, compares the cros.<!ing of 

 wool and mutton type sheep. The work reported, covering five years, gives the 

 results in crossing Lincoln. Leicester, and Border-Leicester rams with Merino 

 ewes. The numljor of ewes employed was 218. 



Exclusive of lambs, the average body weights of the three cros.ses for all 

 ages were as follows: Lincoln-Merino 107 lbs. Hi oz., I>eicester-Merino 106 

 lbs. 6J oz., Border Leicester-Merino 117 lbs. 2 oz. In wool weight, the Lincoln 

 cross wethers average 1 lb. 4 oz. over the Leicester cross and practically 1 lb. 

 over the Border-Leicester cross. With the ewes tlie differences were 1 lb. 1 oz. 

 and 10 oz., respectively, in favor of the Lincoln. 



The wool averaged in price for the whole period as follows: Lincoln-Merino 

 13.19d. (26.2 cts.) per pound, Leicester-Merino 13.71d., and Border Leicester- 

 Merino 13.89d.
