The purposes of this study were:1) to review the land use history of Oak Creek watershed since European settlement. And 2) to consider the human-caused impacts and their effects associated with different land uses. The study area was classified into three land use patterns: residential,agricultural, and forested areas.Since the European...
This study was designed to confirm or refute the tenderizing
effect of ultra-hydrostatic pressure on warm excised pre-rigor
muscle, plus to take a thorough look at its effect on some meat
characteristics of economic importance.
Samples for the experiment were obtained from animals (cattle
and sheep) slaughtered at Oregon State...
Electrical stimulation of beef carcasses (n=18) did not cause a
significant reduction in microbial population on three different sampling
positions immediately following slaughter. In constrast, significant
microbial reduction (P > 0.05) was found at position 2 (muscle
above aitch bone), but not at position 1 (inside of neck) or position...
A two-part study was conducted to investigate some of the nutritional
relationships between dietary tri-o-cresylphosphate (TOCP), a
toxic stress material, and dietary vitamin E and selenium. In part
one, growth rate of male weanling Long-Evans rats and day-old
Japanese quail (Coturnix coturnix japonica) was used to determine the
protective action...
Objectives of this study were to ascertain the effect of fat
and urea, used alone or in combination, on rumen cellulose digestion
in vitro.
A closed in vitro system (24 hour digestion) was used with a
5 x 4 factorial arrangement of treatments to study the effect of added
corn...
Meadowfoam (Limnanthes alba) is a winter annual oilseed crop
native to the Pacific Coast states. Seven experiments were conducted
to evaluate extracted meadowfoam meal (MFM) as a feedstuff
for poultry, rabbits and sheep.
Three experiments were conducted to evaluate MFM as a protein
supplement for broiler chicks and weanling rabbits....
Two management systems were evaluated in terms of the effects on
calf growth, on calf weight produced per cow per year, and on reproductive
performance of fall calving cows. The alternative management
systems tested were twin foster calf production and, delayed weaning,
production of single suckled calves weaned at the...
Three levels of dietary crude protein (8.6, 11.4, and 17.2) were
fed to 24 pony mares to determine the effects on the estrous cycle,
conception rate, and serum progesterone concentrations. Mares were allotted into three treatment groups designated as low protein (LP),
medium protein (MP), and high protein (HP). Following...
Most of the nutritionally related difficulties of winter feeding
deer apparently result from either poor acceptability of artificial
rations or digestive disturbances that result from feeding starved
animals feeds to which they are not accustomed. Reported in this
thesis are studies conducted with both captive and wild deer concerning
acceptability...
