Relationship of dietary crude protein to factors in uterine secretions and plasma in high producing postpartum dairy cows

Creator:: Jordan, Ellen Rae
Abstract:: Eighteen multiparous, high producing (7,836 kg 4% FCM) Holstein dairy cows were assigned randomly to iso- . caloric rations containing either 12 or 23% crude protein (CP) on day 40 postpartum. After a 10-day adaptation period, uterine secretion and blood samples were collected on the day of estrus (day 0-1),...

Utilization of dietary protein by the mussel, Mytilus edulis trossulus (Linnaeus 1758)

Creator:: Kreeger, Daniel A.
Abstract:: Protein microcapsules (PM) were developed as a tool for investigating aspects of dietary protein utilization by mussels, Mytilus edulis trossulus. Digestion of PM in vitro by protease, trypsin, amylase and extracts from the gut of mussels varied significantly depending on the type of protein encapsulated or whether carbohydrates were added...

Transmission of "Salmon Poisoning" disease to dogs by Nanophyetus salmincola eggs

Creator:: Nyberg, Peter Albert
Abstract:: The presence of the etiologic agent of "salmon poisoning" disease, Neorickettsia helminthoeca, was demonstrated in eggs of the trematode vector, Nanophyetus salmincola. Three dogs were given 100,000 and one dog 82,000 ground fluke eggs by intraperitoneal injection. The four animals developed "salmon poisoning" disease and died. One of these dogs...

Flow cytometric evaluation of spermatozoan nuclear chromatin structure and viability

Creator:: Ballachey, Brenda Elizabeth
Abstract:: I. Frozen bovine semen samples were measured by flow cytometry (FCM) to determine if FCM analyses could be useful for sperm quality evaluation and prediction of bull fertility. Fluorescent dyes utilized were acridine orange, to measure sperm nuclear chromatin heterogeneity by quantifying susceptibility of the chromatin to denaturation, and rhodamine...

An appraisal of risks and benefits in the provision of selenium for beef cattle

Creator:: Hathaway, Ronald L.
Abstract:: Three experimental grazing trials were conducted to explore the hypothesis that in the Klamath Basin, a higher level of selenium supplementation is necessary than those proven adequate elsewhere. Two forage species were investigated: Festuca arundinaeca and Agropyron repens, in 0.61 hectare plots, both grown in a selenium deficient soil area....

Ecological aspects of kin discriminating behavior with implications of functional value

Creator:: Hokit, D. Grant
Abstract:: To assess the context dependence of kin discriminating behavior, I examined kin-biased aggregation behavior in tadpoles of R. cascadae in different ecological conditions. I manipulated food distribution, predator presence, thermal heterogeneity, and relatedness in a multifactorial mesocosm experiment. All four factors interacted to influence tadpole dispersion. My results suggest that...

Cannibalism in larvae of the long-toed salamander, Ambystoma macrodactylum

Creator:: Wildy, Erica Lynn
Abstract:: Predator-prey interactions have historically been studied to explain patterns of organization observed in populations and communities. They have also been important in understanding the evolution of antipredator responses in prey and counterstrategies in predators. Despite the breadth of knowledge that exists for heterospecific interactions, relatively few studies have investigated the...

Courtship-induced changes in female sexual receptivity : a neuroendocrine study in an amphibian

Creator:: Propper, Catherine R.
Abstract:: This thesis describes studies that investigated 1) the effects of courtship on the neuroendocrine system of female rough-skinned newts, Taricha granulosa, and 2) whether the observed courtship-induced neuroendocrine changes affected female sexual receptivity. Sexual behaviors of female T. granulosa changed dramatically during courtship. Initially, females exhibited unreceptive behaviors to a...

The influence of social structure and molecular evolution on genetic diversity in the sperm whale (Physeter macrocephalus)

Creator:: Alexander, Alana
Abstract:: The sperm whale (Physeter macrocephalus) shows some of the most derived characteristics of any mammal: a large body size, large brain, complex social organization and a capacity for deep foraging dives that few other marine mammals can match. Despite a history of exploitation that removed hundreds of thousands of individuals,...
