ANIMAL PRODUCTION. 279 



nishiiiff the same amomit of protein with the ration, but there is no advantage 

 in using it when a more palatable feed is at hand. 



When cotton-seed meal was contrasted with oil meal for 154 days, the daily 

 cost of feed per horse was only 0.1 ct. higher with the cotton-seed than with oil 

 uieal. In a final test of 77 days, the 2 rations gave very uniform results, but 

 on the whole the cotton-seed meal gave more satisfaction. The ration contain- 

 ing it was fully as palatable and as efhcient in maintaining the health and 

 weight of the horses. It was less laxative and with cotton-seed meal at $30 per 

 ton a little cheaper. 



Among the conclusions drawn are the following : " The health, spirit, and 

 endurance of work horses were the same when fed corn with a moderate amount 

 of oil meal, or gluten feed, or cotton-seed meal, as when fed a corn and oats 

 ration supplying a similar nutritive ratio. The ration of corn and oil meal 

 maintained the weight, flesh, and appearance of the horses fully as well and 

 with less expense than the one of similar nutritive value composed of corn and 

 oats." 



The sheep of the Carpathian mountains, C. de Beruosak (Bui. Mens. Off. 

 Rensrig. Agr. [Parii^'i, 9 Hi) 10), No. 2, pp. l.'i5~lGl). — This gives an account of 

 the sheep industry in the mountain region of northeastern Hungary. 



The Raclva sheep, a native dairy breed, the chief characteristic of which is 

 hardiness, averages about 73 liters of milk during the pasture season, from 

 which about 10 kg. of cheese are made. Details of making this cheese, called 

 " lipto," are given. The wool, which is of poor quality, is sheared twice each 

 year, yielding a total clip of about 1 kg. per head. 



The author also reports his experience in importing improved breeds of 

 .sheep from Friesland which, when crossed with the natives, improve the quan- 

 tity and quality of wool and increase the yield of milk. 



r Swine husbandry in foreign countries], W. W. Ballantyne et al. 

 (Ottfiwa: Govt., 1910, pp. 60. pis. 21, figs. 6).— This is a report of the Canadian 

 connnission appointed to investigate the swine breeding of other countries. 



The countries visited were Denmark, Holland, England, Scotland, and Ire- 

 land. The methods of feeding swine and curing and marketing pork products, 

 as practiced in those countries, are reported in detail. It is pointetl out that 

 for successful swine raising in Canada more cooperation is necessary among 

 producers in selling their products. The erection of coopei'ative packing houses 

 is reconunended. 



How to keep hens for profit, C. S. Valentine {Ncxd York, 1910. pp. IX-\- 

 298, pis. 16). — A practical book on poultry, in which the importance of the 

 poultry industi'y to the nation is discussed, and the l>est methcds of breeding, 

 feeding, and managing fowls are given in detail. Special attention is given 

 to American i)reeds of fowl and the Indian Runner duck. 



[Ostrich industry in Uruguay]. F. W. GoniNr: (.l/o. Cons, and Trade Rpts. 

 [V. .v.], 1910, No. 35.5, p. 8.'/).— The consul at Montevideo reports that the 

 nandu, or native ostrich, has recently decreased to such an extent that the 

 government has taken steps to protect it. 



This species of ostrich (Rhea americana). which is easily tamed and domesti- 

 cated, is a native of I^ruguay and Argentina. It resembles somewhat the 

 African bird but is smaller, of a mixed gray color, and has 3 toes. When 

 mature the birds weigh from SO to 100 lbs. each and are about 5 ft. in height. 

 The eggs average 2 lbs. each and i*equli'e 40 days for incubation, which is done 

 by the male. Each bird yields about 000 gm. (1.32 lbs.) of marketable feathers, 

 worth fi-oni .$.3.10 to .$0.20 per kilogram in Montevideo. In lOO!) nearly 2.1,000 

 kg. (.")r>,000 li>s.) was exi»orted to France, (iermany, Spain, and the United 

 States.
