To reduce the loss of feeding calves during the nursing period
and to conserve milk for human consumption research has been conducted
to develop milk replacer formulas which result in calf performance
comparable to that of milk. In the first section of this investigation
different aspects of utilization of fats,...
The goal of these experiments was to ensile combinations of shrimp or crab waste
with perennial ryegrass straw and analyze it for silage quality and ruminal degradability.
The rapid deterioration of seafood wastes required initial preservation prior to ensiling
to minimize odor production and protein breakdown. Eight experiments were conducted...

Two experiments were conducted to evaluate the influence of a yeast-derived cell wall preparation (YCW) on forage intake and digestibility, ruminal fermentation characteristics, serum prolactin and prolactin stores, and milk production in beef cattle consuming high-alkaloid tall fescue straw. In Exp. 1, 16 Angus x Hereford ruminally cannulated steers (200...
In recent years, small poultry producers have been interested in finding an alternative for corn and soybean for a variety of reasons. Health concerns related to either naturally occurring isoflavones (phytoestrogens) or their genetically modified organism (GMO) status are the primary considerations behind this trend. Secondly, the recent high prices...
Five simulated precipitation patterns characteristic of the Columbia
Basin and Plateau region and six fertilization rates were evaluated
for their effect on percent crude protein, percent in vitro dry matter
digestibility, fiber content, and yield of wheat aftermath on a commercial
farm in north central Oregon.
The higher moisture regimes...
Alfalfa accumulates phytoestrogens and when ingested binds the estrogen receptor and induces morphological changes similar to endogenous estrogens. The objective of this study is to evaluate morphological changes in uteri, vulva, and teats of ovariectomized prepubertal ewe lambs. Eighteen prepubertal ewe lambs were ovariectomized in November 2000 and fed nonestrogenic...
Alfalfa is an important crop in Jackson, Josephine and Douglas counties of southern Oregon. Its farm value is about $2½ million per year. Many varieties are available for planting
in the area. More than 80 alfalfa varieties and experimental selections have been evaluated for hay production since 1959
at the...
In broiler chickens, hepatic lipid metabolism plays a significant role in whole body and muscle fatty acid (FA) incorporation. Flax seed is a rich source of α-linolenic acid and can be used to increase n-3 FA in poultry meat. Previous studies have shown that flax seed in combination with carbohydrase...
Five experiments were conducted to investigate the
effect of dietary fish meal on the incidence of Sudden Death
Syndrome (SDS) in broiler chickens. Growth, feed
efficiency, total mortality and mortality due to SDS were
evaluated. Necropsy examination was performed on broilers
suspected of dying from SDS. Liver lipid and fatty...
Several studies have been conducted to examine the
utilization of non-protein nitrogen by the New Zealand
White rabbit.
Soybean meal (SBM) or urea added to a low protein (13%
CP) diet and a positive control diet were fed to does and
their offspring during a nine month experiment. Urea and...
Three experiments were conducted to evaluate the influence of quality of
supplemental alfalfa quality on beef cattle consuming low-quality meadow grass (MG)
roughages. Fifteen steers (250 kg) were assigned randomly to one of three treatments: 1)
meadow grass (5.2% CP), no supplement (MNS); 2) meadow grass plus high quality
alfalfa...
