A frozen concentrate (>10⁹ cfu/ml) of a human strain of Lactobacillus
lactis (strain MLC) was fed to swine. Bottle feeding resulted
in reduced fecal coliform counts and incidence of scouring in nursing
pigs. In one group of pigs treated 54 days, the Lactobacillus to coliform
ratio was 1280:1; in the...
The object of this study was to observe the effect of tallow plus
urea in vitro and in vivo. The study was carried out in three parts;
an in vitro fermentation study, a metabolism trial and a feedlot trial.
The in vitro study was conducted using a 4 x 2...
Three studies during three consecutive summers were conducted
at the Squaw Butte Experiment Station to estimate relative and quantitative
forage intake of spring and fall calving cow-calf pairs on
summer range. In a drylot study (experiment 1) individual animal
consumption of fescue or meadow hay cut at 2- to 10-day...
The objectives of this study were to determine the diets of
cattle at risk to DABPE on stress and inciting pastures and to determine
if segregated feeding groups of cattle displayed differential
susceptibility to DABPE.
Stress pastures were classified and mapped by plant communities
and segregated feeding group areas. Cattle...
One hundred two mature blackface crossbred ewes were randomly
divided into three equal groups to examine the effects of feeding
management during mating on blood chemistry, weight change and
subsequent reproductive performance.
Group I was kept in drylot from 17 days before through 17 days
after the start of mating....
Rapid copper depletion without clinical symptoms of copper deficiency
was found in cattle under natural Klamath basin conditions.
Copper metabolism was influenced by grass species fed to the animals.
Tall fescue, Festuca arundinacea Schreb. 'Altar and 'Fawn', reduced
liver copper stores and decreased blood plasma copper and ceruloplasmin
activity to...
Three products derived from shrimp processing waste (Pandalus
jordani) and a protein concentrate extracted from king crab waste
(Paralithodes camschatica) were evaluated as feed supplements for
standard dark and sapphire pelter mink (Mustela vison) replacing
approximately 10 and/or 20 percent of the protein in a standard wet
diet (33 percent...
The heat exchange of individuals in a foraging mixed population
of Zonotrichia leucophrys and Zonotrichia atricapilla in western
Oregon is analyzed with respect to the direction of stance and
feeding location. Values for heat gain or loss in the field were
generated from a model that estimates the equivalent black-body...
