GRASS SILAGE (cont. from page 3) 



These materials have been success- 

 fully aj^plied to large lots of silage 

 ( 120 tons ) on the University farm. 

 The treated silage was excellent, with 

 good color and texture. It did not 

 leave any objectionable odor on 

 hands and clothing or in the barn 

 after feeding. Above all, it was pala- 

 table to a herd of 70 cows, and milk 

 production was well maintained. 



The average moisture content of 

 the green crop preserved with bisul- 

 fite was 76.7 percent, and with Ky- 

 lage 77.4 percent. These compounds 

 overcame the disadvantage of high 

 water content, which would have 

 caused an inferior silage. 



Of course, silage made with corn 

 meal or other ground grains has a 

 higher feeding value than that made 

 with chemicals because the grains 

 add nutrients to the silage. 



Determining volatile acids and bases as a 

 measure of quality in silage.

disease. Workers in the laboratory 

 have found another use for fecal 

 streptococci — this time, to detect 

 contamination in frozen foods. 



Detergents are newcomers to the 

 modern kitchen. In large concentra- 

 tions, some of them can kill bacteria. 

 Because of this killing action, bac- 

 teriologists have tried to determine 

 whether detergents also kill the bac- 

 teria necessary to digest sewage in 

 septic tanks. In our work, we have 

 found that detergents did not harm 

 the efficiency of the tanks. 



Animal manure shortage has cre- 

 ated an interest in dried sewage 

 sludge as an inexpensive substitute. 



Studies here have indicated that this 

 addition would not endanger health. 



In surgery, the department has re- 

 cently cooperated with the Spring- 

 field Hospital to test the effect of a 

 new form of the antibiotic terramy- 

 cin, in combination with other anti- 

 biotics, on fecal ilora ( intestinal 

 bacteria ) . This could have an out- 

 standing effect in surgery of the large 

 intestine, and will probably decrease 

 the possibility of generalized periton- 

 itis after radical operations. 



With increased enrollment at the 

 University, a larger budget, and ad- 

 ditional outside research grants, the 

 future of bacteriological research ap- 

 pears to be a bright one.
