The study involved three separate research efforts
in which 10 Holstein calves and 85 purebred Hampshire and
Suffolk ewe and ram lambs were employed. The objectives of
the experiments were to characterize appetite, describe its
inheritance and evaluate its associations with animal
performance.
In the calf experiment, appetite was determined...
Several experiments involving broilers, chicks, layers, roosters,
poults and breeder turkeys were conducted with the primary objective
of examining research methods for evaluating poultry feed grains, their
additives and supplements. A secondary objective was to improve and
maximize the production responses of poultry fed locally grown grains.
Feed grain research...
Preliminary studies with a dog (Canis familiaris) and a coyote
(Canis latrans) showed that these carnivores can serve as definitive
hosts in the life cycle of Sarcocystis fusiformis of cattle (Bos
taurus) and a microscopic Sarcocystis of mule deer (Odocoileus
hemionus hemionus). Preliminary studies to determine effects of the
cervine...
Inclusion of substantial levels of raw-frozen Pacific hake
(Merluccius productus) in diets of ranch-raised mink (Mustela vison)
causes a large percentage of animals to develop an abnormal condition
termed "cotton fur" (CF), characterized by depressed body
weight, microcytic-hypochromic anemia and a failure of under-fur
pigmentation. Observations by several groups of...
Elodea densa Planch. was exposed to diquat (6, 7 dihydrodipyrido [1,2-a: 2', 1'-c] pyrazinediium dibromide), alone and in combination
with disodium endothall (disodium salt of 7-oxabicyclo [2.2.1]
heptane-2, 3-dicarboxyclic acid), and copper sulfate pentahydrate.
Studies were conducted in coastal lakes of Oregon infested with E.
densa. Dichlobenil (2, 6 dichlorobenzonitrile)...
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...
A population of Columbian white-tailed deer (CWTD) was studied on a
refuge (790 ha) in southwestern Washington during 1972-77. Quality of
habitat was considered good for these deer and total population size remained
between 164-230 as determined by mark-recapture methods during
November. Population size declined significantly between the winters of...
