FISHERY INDUSTRIES OF THE UNITED STATES, 1930 123 



societies has been extended to the bureau in connection with these 

 tests. 



The bureau is continuing its cooperative tests, in extending its 

 nutrition studies to farm animals, with various Federal and State 

 agricultural experiment stations. At the present time, these studies 

 are being confined to various fish and shellfish meals, but it is hoped 

 to extend them to other marine products suitable for use in animal 

 nutrition such as fish oils and kelp meal. Notable among these 

 cooperative stations may be mentioned the United States Department 

 of Agriculture, Bureau of Animal Industry, Experimental Farm at 

 Beltsville, Md.; the Ohio Agricultural Experiment Station, Wooster, 

 Ohio; and Cornell University Agricultural Experiment Station, 

 Ithaca, N. Y. \ 



The number of nutrition studies relating to and depending on other 

 phases of the bureau's technological investigations, together with 

 demands for nutrition investigations from the industry, have com- 

 pelled the bureau to establish its own nutrition laboratory. The 

 investigations already planned will tax the facilities of the new 

 nutrition laboratory to the utmost for at least a year or more. The 

 experimental animal most universally used, namely, the albino rat, 

 is used in our nutrition studies. 



In cooperation with this bureau, the division of animal husbandry, 

 Bureau of Animal Industry, United States Department of Agricul- 

 ture, has completed recently at the experiment farm located at Belts- 

 ville, Md., feeding tests with sheep in which the nutritive value of 

 shrimp meal has been studied over a period of approximately two 

 years. The sheep were divided into two lots. Lot 1 received a 

 ration of 8 parts oats, 8 parts bran, 4 parts corn, and 2 parts of old 

 process linseed oil meal by weight. Lot 2 received the same ration 

 except that the linseed oil meal was replaced with an equal quantity 

 of shrimp meal. Both lots were fed equal amounts of western alfalfa 

 hay and equal amounts of corn ensilage. The total gain in pounds 

 of the sheep on the linseed oil meal ration was 556 in 1929, whereas 

 sheep on the shrimp meal ration gained a total of 582 pounds in 1929. 

 In 1930, each lot gained 475 pounds. These two rations were of 

 approximately equal value in wool production. The data obtained 

 from these tests indicates that shrimp meal is just as valuable as 

 old process linseed oil meal for feeding sheep when used up to 10 

 per cent of the total grain mixture. 



GIOUCESTER LABORATORY 



The bureau is establishing a large field laboratory at Gloucester, 

 Mass., for the general conduct of technological research, including 

 the following activities: Refrigeration, smoking, canning, bacteri- 

 ology of industrial processes, by-products, and production methods. 



MARKET AND INDUSTRIAL SURVEYS 



Market and industrial surveys are made to supply the trade with 

 useful market information regarding the distribution and consump- 

 tion of fishery products and to supply descriptive and economic 

 data on our fisheries and fishery industries.
