Response of market hogs to periodic changes among nutritionally similar rations

Creator:: Hamstreet, John Leslie, 1940-
Abstract:: 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;...

Energy-protein relationships in high-fat rations for growing-finishing swine

Creator:: Pate, Findlay Moye
Abstract:: 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...

Effect of feeding concentrates of Lactobacillus lactis on fecal bacterial flora, scouring, and weight gain in swine

Creator:: Sheggeby, Gene G.
Abstract:: 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 nutritive interrelationships of tallow and urea in ruminants

Creator:: Phillips, Ralph L.
Abstract:: 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...

Some psychophysiological aspects of taste and eating rate in cattle, sheep, and horses

Creator:: Randall, Ronald Patrick
Resource Type:: Dissertation
Full Text:: used in a reversal study to determine the effects of ration ingredients and level of feeding on their

Forage intake and related performance criteria of spring and fall calving cow-calf pairs on summer range

Creator:: Kartchner, Rex John
Abstract:: 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...

Biological and economic effects of flushing and creep feeding in sheep

Creator:: Taiwo, Bolaji
Abstract:: 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....

Copper deficiency in cattle in the Klamath Basin

Creator:: Stoszek, Milena Jaroslava
Abstract:: 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...

The effect of feeding tallow, urea and protected tallow on in vivo nutrient digestion in sheep

Creator:: Aseltine, Mark Stephen
Abstract:: 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...
