Optimum combination of time and rumen fluid in three in vitro techniques used to predict forage digestibility

Creator:

McNeill, David Gingles

Resource Type:

Masters Thesis
Stimulatory effect of trace elements on cellulose digestion by washed suspensions of rumen microorganisms

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...

Masters Thesis
The effect of varying levels of readily available carbohydrates on urea utilization

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%...

Masters Thesis
Taste responses in Columbian black-tailed deer (Odocoileus hemionus columbianus (Richardson))

Creator:

Crawford, James Charles

Abstract:

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...

Masters Thesis
Taste reactions in Columbian black-tailed deer

Creator:

Rice, Patrick Ralph

Abstract:

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...

Resource Type:

Masters Thesis
The effect of fats and urea on in vitro cellulose digestion

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
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...

Resource Type:

Masters Thesis
The effects of urea supplementation on feather meal and hair meal utilization by ruminants

Creator:

Daugherty, Dennis A.

Resource Type:

Masters Thesis
Palatability for cattle of four varieties of ryegrass

Creator:

Aderibigbe, Adeshina O.

Abstract:

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...
