Commercial hog diets in the United States commonly contain lipid sources high in polyunsaturated fatty acids, most notably linoleic acid (18:2). This may result in greater deposits of linoleic acid in pork adipose tissue, contributing to an increased potential for lipid oxidation, high n-6/n-3 fatty acid ratio and increased fat...
Methods to improve the efficacy of swine barley rations were
evaluated. A literature review pertaining to the subject, three feeding
trials involving 104 swine, and a laboratory investigation were
used in the study.
The effects of pelleting with a new modified pellet die that
produces a dense pellet; supplementation with...
A series of four animal experiments utilizing 129 pigs
and associated laboratory studies was conducted to study the causes
of the lowered performance on high barley rations fed to swine. Previous
work at this Station has shown barley to have a value of 80-85
percent of corn for swine, and...
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...
"In conclusion it may be said that kale is almost
a winter maintenance ration for swine, but when fed in
addition with a little grain or skim milk, good growths
will be made. Especially is this true of young pigs as
is denoted by the tables. Taking all in all,...
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...
Tests using paired pens of barrows were conducted during a 13 month
period to determine the influence of protein level of the ration on
production traits of market barrows. One member of each pair of six to
ten full- and half-sib pairs was randomly allotted to each pen group;
thus,...
The nutritive values of two fishery by-products, i.e. fish
protein hydrolysate (FPH) and liquefied fish (LF), were studied.
Three trials using Hubbard broilers, and Yorkshire pigs (starter
and grower phase) were conducted. The FPH was used in the broiler
trial and LF in the swine grower trial as supplemental protein...
