Creator:: Martinez, Andres
Abstract:: 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...

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...
Resource Type:: Masters Thesis
Full Text:: coefficients were calculated. Erwin et al. (1956) reported a significant increase in daily gains of steers

Creator:: Kezar, Wesley W.
Abstract:: 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...
Resource Type:: Masters Thesis
Full Text:: acid analysis (VFA) were essentially those outlined by Erwin et al. (1961). Ten ml of the liquid

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...
Resource Type:: Dissertation
Full Text:: to heat and pressure. Fat Performance and Digestibility Erwin, Dyer and Ensminger (1956) reported

Creator:: Fowle, Kenneth Edward
Abstract:: 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...
Resource Type:: Dissertation
Full Text:: Two - Component Means for Areas, Variance 55 and F Values 20 Means of Observations During Starvation

Creator:: Wright, Rodney Joseph
Abstract:: 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%...
Resource Type:: Masters Thesis
Full Text:: r.p.m. for 20 minutes (Erwin et al. , 1961). The supernatant was refrigerated until analyzed. VFA
