24 N. H. Agric. Experiment Station [Bui. 270 



Although the 28,966 birds handled during the past year represent a 

 slight decrease over the previous season, a renewal of interest may re- 

 sult from the present attempts to standardize the New Hampshire Red 

 breed. The work is in charge of Frank D. Reed. {Miscellaneous

Studying Fatty Materials in Feeds 



Further study in the department of agricultural and biological chem- 

 istry has concerned the methods of determining the lipids or fatty 

 materials in typical feeds. 



Two procedures were compared — the official A. 0. A. C. and the 

 Kumagawa. Alfalfa hay, corn meal and mixed feed were used in this 

 comparative work which showed that the Kumagawa method gives a 

 higher amount of total material extracted and a higher content of 

 the fatty acids. 



Completeness of extraction was checked on mixed samples of feed. 

 More lipid material was removed by the Kumagawa method after the 

 samples had previously been extracted with ether by the A. 0. A. C. 

 method. 



While the Kumagawa plan extracts more of the true fatty material 

 from the samples, it has the weakness of losing up to 20 per cent of 

 the extracted material in the wash water. {Hatch Fund) 



Inspection Service 



Feeding Stuffs. In the enforcement of the law regulating the sale 

 of concentrated commercial feeding stuffs, 283 brands were analyzed 

 for the state department of agriculture. These analyses required about 

 2,200 individual determinations. 



Fertilizers. In the enforcement of the law regulating the sale of 

 commercial fertilizers, 127 brands were analyzed for the state depart- 

 ment of agriculture. These analyses required about 850 individual 

 determinations. 



Samples of soils, peats, leaf molds, fertilizers, feeding stuffs and 

 other materials have been sent to the department by residents of the 

 state. Of these 239 have been analyzed, involving about 391 in- 

 dividual determinations. 



Seed Inspection. The regular seed inspection work for the State 

 Department of Agriculture was conducted as usual. During the sea- 

 son of 1932, 379 samples of seed were handled in the laboratory. Of 

 this number 357 were collected by the State Inspector and are reported 

 in Bulletin No. 267. The remaining twenty-two samples were sent in 

 by private individuals. 



Advanced Registry. Advanced Register and Register of Merit tests 

 were made on 311 cows during the year. There were 282 cows entered 

 for breed herd tests. 



Seed Certification. Of 147.25 acres entered for certification in 1931, 

 129.75 acres passed final inspection. {Miscellaneous Income)
