ANIMAL PRODUCTION. 865 



coru is not now economical. Alfalfa bay fed in combination witb corn silage 

 during tbe first 56 days, witb corn added to tbe ration for the balance of tbe 

 period, reduced tbe cost of gains, but also decreased tbe rate of gain as com- 

 pared with tbe ration differing by tbe addition of cotton-seed meal. 



"Corn silage at $3.50 per ton as tbe sole rongbage is more economical tbau 

 corn silage and alfalfa bay combined wben alfalfa bay costs $15 l)er ton. 



"Tbe cost of producing a pound of gain was considerably less during the 

 first period, when roughage only was fe<l, than during tbe second period, when 

 grain also was fed. 



" Cattle receiving no corn silage but fed corn from the beginning of tbe 

 experiment consumed more dry matter daily than those fed corn silage without 

 corn." 



Cottonseed meal for feeding beef cattle, W. F. Wabd {U. S. Dept. Agr.. 

 Fanners' Bui. 655 (J 915). pp. 8). — This is a popular review of work previously 

 reported from other sources, giving tbe results of experiments in feeding 

 cotton-seed meal to beef cattle in varying proportions and offering suggestions 

 for its profitable u.se. " If cotton-seed meal does not cost over $34 a ton, it can 

 probably be used to advantage in wintering the breeding herd. . . . Cotton-seed 

 cake can be used very profitably as a supplemental feed for fattening cattle 

 on pasture. Five times as many farmers should be using cotton-seed meal as 

 are doing so at tbe present time." 



Jersey- Angus cattle, A. H. Kuhlman (Jour. Heredity, 6 (1915), No. 2, pp. 

 68-72. figs. 6). — Breeding trials being conducted by F. B. Samuelson in Eng- 

 land are reported in which Jersey cows were mated with an Angus bnll. The 

 Fi individuals were mated, as were also the F2 individuals. The crossbred 

 cows of the Fi generation showed a high yield of milk and milk fat, their udders 

 were very uniform and good-sized, and they were more hardy than their dams, 

 requiring less close housing during the winter. Tbe F2 individuals showed 

 marked variations in conformation and color, indicating a segi'egation and recom- 

 bination of the characters of the original parents. It is stated that the Jersey- 

 Angus crosses bring as good prices as most beef cattle, and tbe possibilities of 

 establishing a new breed based upon this cross are being considered. 



Shorthorn cattle in Missouri, B. O. Cowan (Missouri Bd. Agr. Mo. Bui.. 

 12 (1914), No. 12, pp. 91, figs. iS).— This is a history of tbe development of tbe 

 Shorthorn breed of cattle in Missouri and includes a list of Shorthorn breeders 

 in that State. 



The present status of the cattle industry in Canada, H. S. Arkell (Internnt. 

 Inst. Agr. [Rome], Mo. Bui. Agr. Intel, and Plant Diseases, 5 (1914), No. 10, pp. 

 1255-1263) . — A statistical review of tbe cattle indu.stry in Canada, showing tbe 

 distribution of dairy and beef cattle in tbe various Provinces, the exports and 

 imports of cattle and beef, and tbe status of tbe various record associations. 



Cattle raising in the Belgian Kongo, F. Kolbe (Jahrb. Wiss. u. Prakt. Tier- 

 zucht. 9 (191.)) . pp. 208-222. figs. 5). — A general discussion of the native breeds 

 of cattle found in the Belgian Kongo. 



The value of castration of Deccan bullocks, J. B. Knight (Dept. Agr. Bow- 

 bay Bui. 62 (1914), PP- 6, pis. 2). — In this experiment -oith Deccan bullocks, it 

 was demonstrated that neither early nor late castration materially affected the 

 weight of tbe bullocks. There was a greater proportionate development in the 

 hind quarters of early-castrated than of late-castrated animals. Tbe strength 

 and hardiness were not impaired by early castration, while tbe docility was 

 markedly improved and the activity was greater.
