Eight experiments, two with poults and six with chicks, were
undertaken to determine the requirement for supplemental folic acid
as related to protein level and major protein source. Protein levels
for chicks and poults were 21, and 28 or 28 and 32%, respectively.
Major protein sources were soybean meal, fish...
The objective of this study was to investigate the effect of inorganic
and organic components of molasses on the laxative problem
encountered when molasses makes up a large portion of livestock
rations. In a series of four trials 280 male Long Evans rats weighing
approximately 50 grams each were placed...
An experiment was conducted during the period November 1967
to November 1968 at Oregon State University (OSU) and the Umatilla
Branch Experiment Station (BES) at Hermiston, two trials at each
location, to answer several questions: (1) could comparable rations
for swine be formulated by a computer on a least-cost basis;...
An experiment was conducted with 48 Yorkshire x Berkshire
crossbred barrows to evaluate the influence of varying Calorie: protein ratios in high-fat rations on performance and carcass quality
of growing-finishing swine. Pigs were individually fed rations containing
three levels of fat (lard): 0, 15 and 30 percent. Each fat
level...
Chemical and biological evaluations were conducted to provide
chemical composition and digestibility information, in addition to
yield data, for silage corn varieties produced on poorly drained
Dayton soil series. Each variety was subjected to a Kjeldahl nitrogen,
acid detergent fiber, acid detergent lignin, cell wall, and
residual ash test. Subsequently...
Seven in vitro trials were conducted to compare the effects of
soaking annual ryegrass straw in solutions of sodium hydroxide (Na₄OH),
potassium hydroxide (KOH), ammonium hydroxide (NH₄OH), or sodium
formate (NaCHO₂) at varying levels. Dry matter digestibility (DDM)
was the criterion used to measure treatment response. A 3 x 3...
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...
