ANIMAL PRODUCTION. 769 



of its tall, by its horned ewes, and the frequent occurrence, esjieeially among 

 the rams, of horns in groups of 4 or more. These characters have persisted in 

 common since at latest the middle of the sixteenth century till the present day." 



It is presumed that improved breeds by a process of selection have gradually 

 usurped the place of the more primitive race. 



[Pig-feeding experiments], J. M. Scott (Florida Sta. Rpf. 1913, />/). XTII- 

 XIX). — Two lots of four 75-lb. pigs each were fed during 46 days as follows: 

 Lot 1, shelled corn and green cowpeas; lot 2, corn and green sorghum, equal 

 amounts by weight being fed so that for each pound of corn a pound of green 

 feed was given. Lot 1 made an average daily gain per head of 0.43 lb., costing 

 12.2 cts. per pound of gain : lot 2, 0.36 lb., costing 14.7 cts. per pound. 



Three lots of pigs were fed during 43 days as follows: Lot 1, shelled corn 

 and green rape; lot 2, shelled corn and peanuts 3:1, with green rape; lot 3. 

 shelled corn and peanuts 1 : 1 with green rape. Lot 1 made an average daily 

 gain per head of 0.6S6 lb. costing 13.9 cts. per pound of gain; lot 2, 0.72 lb., 

 costing 14.6 cts. per pound; and lot 3, 0.774 lb., costing 15.6 cts. \iev pound of 

 gain. It is noted that as the amount of the peanuts in the ration was increased 

 there was a noticeable increase in the average daily gains, but likewise an 

 increase in the cost, and indicating that for pork production peanuts are worth 

 only about 30 or 40 cts. per bushel. 



Growing hogs in Mississippi, E. M. Ranck {Mississippi Sta. Circ, 1914, 

 June 20, pp. 17). — General directions for the breeding, feeding, care, and man- 

 agement of hogs under Mississippi conditions, including hog diseases and a 

 text of a new state law relating to the quarantine and burial of diseased ani- 

 mals, are given. A table showing rotations of forage crops, supplemental feed, 

 etc., is included. 



Swine husbandry in V/ashington, R. C. Ashby and C. F. Monkoe ( Washinff- 

 ton Sta. Popular Bui. 63 (1914), pp. 36, fig. 1). — A popular bulletin on swine 

 husbandry, inchiding methods of feeding, breeding, diseases, and general man- 

 agement. 



Forty years' experience of a practical hog man, A. J. Lovejov ( Springfield, 

 III., 191Jf, pp. 170, figs. 29). — This is a practical treatise on the carp, feeding, and 

 management of swine. 



Studies on the proportions of the horse, L. Van Meldebt (Ann. Gemhloux, 

 24 (WW, Nos. 3, pp. 121-151, figs. 2; 5, pp. 249-274, figs. 4)-— This article 

 reviews the history and development of the horse and the origin of the different 

 tjT)es and classes. Various body measurements of the several types of horses 

 are given and comparisons made in their slope and measurement of shoulder, 

 formation of croup, and other points of conformation. 



Comparative digestion experiments on Equidas, O, Frank (Kiihn Arch., 3 

 (1913), pt. 2, pp. 363-396; abs. in Internat. Inst. Agr. [Rome], Mo. Bui. Agr. 

 Intel, and Plant Diseases, 3 (1914), No. 2, pp. 241, 242).— In 10-day feeding 

 experiments with horses, asses, and their hybrids notable differences were noted 

 in their relative power to utilize feed. Of the horses, the mare, belonging to a 

 thrifty country breed (Belgian), digested the feed, with the exception of pro- 

 tein, better than a Mongolian gelding. In the utilization of crude fiber, fat, 

 and nitrogen-free extract the mules and hinnies were superior to the gelding 

 and inferior to the mare. 



It is concluded from these observations that thrifty breeds of horses can 

 compete in thriftiness with mules. The author has also calculated how much 

 feed each animal consumed per unit of body surface and found that the smaller 

 animal requires the greater energy to keep up its vital processes.
