Analysis of two alternative management systems for the production of fall born beef calves in western Oregon

Creator:: Rosecrans, John Gerald
Abstract:: Two management systems were evaluated in terms of the effects on calf growth, on calf weight produced per cow per year, and on reproductive performance of fall calving cows. The alternative management systems tested were twin foster calf production and, delayed weaning, production of single suckled calves weaned at the...

In vitro hormonal and metabolic control of bovine mammary glucose 6-phosphate dehydrogenase activity

Creator:: Young, Allen Jack
Abstract:: Two studies were conducted to determine the in vitro metabolic and hormonal effects on glucose 6-phosphate dehydrogenase activity (G6PD) in bovine mammary explants. Study I was conducted to determine the effects of palmitoyl CoA (5 and 25 uM), acetate (1 and 10 mM), spermidine (0.4 mM) and putrescine (0.4 mM)...

Some ovarian characteristics of the postpartum rabbit

Creator:: Gjesvold, James Allen
Abstract:: The effects of suckling on several ovarian characteristics were studied in postpartum rabbits. Ovarian weight was found to be significantly greater in rabbits suckled for twelve days than in nonsuckled rabbits autopsied at a similar interval postpartum or in a third group autopsied at parturition. There were no significant differences...

In vitro estradiol-induced protein synthesis in the endometrium of cyclic and steroid-treated ovariectomized ewes

Creator:: Allen, Renee Allana
Abstract:: The ability of ovine endometrium incubated in vitro with estradiol -17(3 to synthesize a specific induced protein (IP) was studied. Endometrium from cycling, pregnant and ovariectomized ewes was used. Twelve ewes were allotted in equal numbers to be sacrificed on days 0 (estrus), 3, 6, or 10 of the estrous...

Transforming shrimp and crab waste into dairy heifer feed

Creator:: Evers, Dale J.
Abstract:: The goal of these experiments was to ensile combinations of shrimp or crab waste with perennial ryegrass straw and analyze it for silage quality and ruminal degradability. The rapid deterioration of seafood wastes required initial preservation prior to ensiling to minimize odor production and protein breakdown. Eight experiments were conducted...

Effects of conjugated linoleic acids on PGE₂, PGF₂α and progesterone production by bovine luteal cells in vitro

Creator:: May, Katherine C. P.
Abstract:: Feeding conjugated linoleic acids (CLA) improves reproductive performance in dairy cows; however, the molecular mechanisms by which CLA improves reproduction are not well understood. Therefore, we evaluated whether the CLA isomers, trans-10, cis-12 CLA and cis-9, trans-11 CLA altered synthesis of steroidogenic hormones in bovine luteal cells by measuring concentrations...

Influence of isolated alfalfa coumestrol on growth of lambs

Creator:: Bahn, Alan Volker
Abstract:: The objective of the thesis was to determine the effects of isolated coumestrol on the growth, carcass characteristics and certain organs of wether lambs. The first of two trials was conducted over an eight week period with two groups of heavy wether lambs. Trial two was conducted over an 11...

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...

Growth and carcass merit of purebred Jersey steer calves finished on grain-based diets at two different energy levels

Creator:: Tschida, Garrett L.
Abstract:: Purebred Jersey steers are often overlooked for beef production due to the perceived poor growth and production. Currently dairy persons marketing their steer offspring are receiving minimal compensation due to lack of demand by beef feeders and a saturated veal market. Twenty purebred Jersey steers were used to evaluate lifetime...
