This study was conducted to investigate the production and processing technology of common ryegrass screenings and to determine
the nutritive value of these screenings for sheep. The animal response
to them was assessed when the sheep were fed on the screenings
alone and in combination with other feedstuffs.
Four in...
The object of the present study was to investigate the stimulatory
or inhibitory effects of barium, boron, bromine, cadmium,
chromium, cobalt, copper, fluorine, iodine, iron, manganese,
molybdenum, nickel, rubidium, selenium, strontium, vanadium, and
zinc upon in vitro rumen microbial activity as measured by the amount
of cellulose digested. Washed suspensions...
The object of this research was to study the effect of readily
available carbohydrates (RAC) upon the utilization of urea in fattening
rations and to determine the effect upon carcass characteristics
that determine quality and yield grades. A 2 x 2 latin square designed
feedlot trial comparing urea at 0.5%...
Taste responses of the Columbian black-tailed deer,
Odocoileus hemionus columbianus (Richardson), were determined
by use of the two-choice preference test method, where the choices
were tap water and tap water-chemical solutions in ascending
concentrations. The chemicals tested were: the sugars, glucose
and sucrose; the sodium salts of chloride (NaC1) and...
This study was conducted to delineate the cause or causes of
winter deaths in deer and to provide information from which emergency
feed could be formulated. Deer were shot at monthly intervals through
the winter in Wallowa County, Oregon. Samples from the rumen, liver,
mandible, blood and feces were taken...
This study involved the use of the two-choice preference test to determine the taste reactions of buck and doe Columbian black-tailed deer (Odocoileus hemionus columbianus) to ascending concentrations of water extracts of Douglas fir, red alder, cascara, western hemlock and bitterbrush; to an ethanol extract of Douglas fir, and to...
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...
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...
The objective of this study was to determine the effect that
ration formulation has on volatilization of gases and offensiveness of
the odor associated with the wastes produced from Holstein replacement
heifers. Six separate experiments were conducted to study the
relationships between different variables on the release of hydrogen
sulfide,...
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...
Five sheep digestion trials with four animals per
treatment and three treatments per trial were conducted to
determine if feeding protected tallow and/or protein would
alter the deleterious effects of feeding urea and tallow
together. Apparent digestibility coefficients, nitrogen
retention and biological values were calculated.
An additional trial was also...
This study was designed to determine the relative
palatability of four varieties of ryegrass (Gulf, Ninak,
Charleston and Billion) based on their relative consumption
by cattle and to further evaluate the relationships between
daily consumption and individual nutrient components of
the grasses. Feedlot trials, chemical analyses for volatile
and nonvolatile...
Pangola digitgrass (Digitaria decumbens), Coastcross-
1 bermudagrass (Cynodon dactylon), and Kazungula
setaria (Setaria sphacelata cv Kazungula) were used in a
two-year study at the C.A.M.P.A. Training Center in
Tampico, Mexico. The objective of the study was to determine
the optimum stocking rate during the grazing season
on these species and...
The objectives of this study were to nutritionally evaluate various
feather and hair meals (FM, HM) as protein supplements for ruminants
and to study the in vitro/in vivo relationships of diets supplemented
with FM and HM.
In vitro (rumen and enzymes) studies, five in vivo digestion
trials and a feedlot...
The objectives of this study were to evaluate the feeding value
and potential toxicity of single cell protein (SCP) when fed to
ruminants.
Three in vivo digestibility trials with lambs, one feedlot trial
with steers and one long term feeding trial of high levels of SCP with
sheep were conducted...
This study involved the use of the two-choice preference test,
where the choices were tap water and tap water-chemical solutions,
to determine the responses of sheep to ascending concentrations of
20 chemicals (taste stimulants). The chemicals tested were: the
sugars, sucrose, maltose, lactose, glucose, fructose and galactose;
the sodium salts...
This study involved the use of the two-choice preference test to determine the taste responses of eight, each, of pygmy goats, normal goats, sheep and cattle to ascending concentrations of sucrose (Suc), sodium chloride (NaC1), acetic acid (HAc) and quinine hydrochloride (QHCI). In addition, sheep and cattle were tested at...
A series of factorial experiments (4 x 4 and 4 x 4 x 4) was designed
to investigate the effects of selected combinations of some
major and trace elements upon in vitro rumen cellulose digestion.
Inocula, varying in ratios of clarified rumen fluid (strained through
No. 50 cheesecloth and centrifuged...
