Organoleptically, flavored yogurts appear to contain lower
levels of acetaldehyde than plain yogurt. This study was undertaken
to seek the reasons for this phenomenon by focusing on the analyses
of acetaldehyde production by yogurt culture bacteria in yogurt base
containing added sucrose and by performing other analyses such as
the...
Previous work in this laboratory revealed that hormone analysis using fecal samples may predict the number of fetuses carried by pregnant ewes at mid- to late gestation. Reliable lambing number prediction is useful to the producer. Using gas chromatography/mass spectrometry the 5α- and 5β-series of pregnanes and selected 4- and...
The main objective of this investigation was to evaluate relationships
between the production and utilization of forage and deer
browsing of hand-planted Douglas-fir seedlings. A secondary purpose
was to study some effects of selected physical and biological
site factors on the survival and growth of fir seedlings.
Field work was...
Unfished populations of cutthroat trout in three small coastal
streams in Oregon were studied from April of 1962 until November
of 1963. Population size, growth rate, and net production were
estimated for study areas in each stream. The nature of seasonal
movement patterns within the study areas and at fish...
