ANIMAL PRODUCTION. 



Harnessing heredity to improve the Nation's live stock, D. S. Burch 

 (U. S. Dept. A(jr. Yearbook 1919, pp. S47-354, flrjfi. 3).— A report of early results 

 from the " better sires — bi'tter stock " campaign of the Bureau of Animal 

 Industry (E. S. R., 42, p. 866.) 



Selling purebred stock to South America, D. Harrell and H. P. JIorcan 

 (C7. 8. Dept. Agr. Yearbook 1919, pp. 369-380, figs. 5).— This article considiMs 

 Brazil, Paraguay, Uruguay, and Argentina as possible importers of purebred 

 stock, particularly cattle, from the United States. Sale prices at the Palermo 

 (Ai-gentina) live stock show of 1919 are tabulated. 



liive stock conditions in Europe, T. Wright and G. A. Bell {V. S. Dept. 

 Agr. Yearbook 1919, pp. ^07-424, fli)S. 6). — The authoi's record observations made 

 in 1919 on the live stock conditions in France. Belgium, Switzerland, Italy, 

 Holland, and Great Britain, and present a table of available census data show- 

 ing the effect of the war on the number of cattle, swine, and sheep in these and 

 other countries. There was a noticeable shortage of swine in all the European 

 countries visited, but in general the decreases in other classes of live stock 

 were not as marked as the authors had expected. There were evidences of 

 careful culling of herds and flocks on the part of many farmers and of a wide- 

 spread interest in purebred stock. Immediate importations of stock on an 

 extensive scale from outside countries is not anticipated. 



Federal supervision of live stock markets, L. D. Hall {U. S. Dept. Agr. 

 Yearbook 1919, pp. 239-248, figs. 4). — An account of the operation of the war- 

 time licensing system for stockyards and of the policies of the Bureau of 

 Markets in administering the system. 



Live stock drought relief work in 1919, G. M. Rommel {U. S. Dept. Agr. 

 Yearbook 1919, pp. 391-405, figs. 12). — This is an account of the measures taken 

 by the Departmenf of Agriculture and cooperating agencies in the summer of 

 1919 to secure the rapid transfer of cattle and sheep from the drought-stricken 

 ranges of Montana, Wyoming, and neighboring States to good grazing areas 

 in the Great Lakes region and in Texas. The successful accomplishment of the 

 task is considered a triumph for cooperative* effort. 



Feeding stuffs inspection, J. I^. Hills, C. H. Jones, G. F. Anderson, and 

 L. H. Flint (Vermont Sta. Bui. 216 (1920), pp. 16-26).— This report on the 

 1919 feeding stuffs inspection consists mainly of lists of brands which did and 

 did not conform to guaranty in respect to protein content. A table gives the 

 observed ranges in protein content of the following materials : Cottonseed meal, 

 linseed meal, gluten feed, hominy feed, corn meal, brewers' dried grains, dried 

 beet pulp, peanut feed, \elvet bean meal, wheat bran, wlieat middlings, wheat 

 mixed feed, red dog, wheat screenings, ground oats, oat hulls, and various kinds 

 of compounded and proprietary feeds. 



Sweet-clover seed screenings not injurious to sheep, C. D. Marsh and 

 G. C. Roe {U. S. Dept. Agr., Dept. Circ. 87 (1920), pp. 7).— Four sheep, weigh- 

 ing from 81 to 99 lbs., were fed for 7 or 8 days on a ration (from 1 to about 

 2 lbs.) of screenings composed mainly of immature seeds of the white sweet 

 clover. They lost in weight somewhat, but later two of them were maintained 

 satisfactorily during nearly 7 weeks of pasture on a 0.7o-lb. ration of screen- 

 ings, making about the same gain as the other two, which recei\'ed bran as a 

 supplement to pasture. In another experiment two sheep gained in weight 

 during a month's feeding on alfalfa hay and screenings. 



In no case was any injurious result noted and the authors, therefore, are 

 unable to confirm reports that sweet-clover seeds may be poisonous to sheep.
