Social Organization And Decision Making In North American Bison: Implications For Management, Ryan A. Shaw May 2012

Social Organization And Decision Making In North American Bison: Implications For Management, Ryan A. Shaw

All Graduate Theses and Dissertations

Social organization varies widely among herbivores, and the level of social organization in bison is widely debated. I hypothesized that when mother-daughter relationships are allowed to develop, bison form long-term associations. In my study, 25 treatment mothers were selected from a free-ranging herd and kept together with their calves, while 25 control females had their calves forcefully removed. Treatment mothers and offspring had by far the greatest number of associations with a greater percentage of individuals with a half weight index (HWI) > 0.50. The strongest associations (HWI > 0.31) were among treatment mothers and their offspring. Moreover, these associations ...


Use Of Rumen Modifiers To Manipulate Ruminal Fermentation And Improve Nutrient Utilization And Lactational Performance Of Dairy Cows, Christopher M. Dschaak May 2012

Use Of Rumen Modifiers To Manipulate Ruminal Fermentation And Improve Nutrient Utilization And Lactational Performance Of Dairy Cows, Christopher M. Dschaak

All Graduate Theses and Dissertations

Overall hypothesis in a series of lactation studies reported in this dissertation was that supplementing different rumen modifiers would have consistent responses on ruminal fermentation and lactational performance under optimal ruminal fermentative conditions. First experiment investigated the influence magnesium exchanged zeolite on ruminal fermentation and lactational performance. Intake of dry matter (DM), milk yield, milk fat concentration, and feed efficiency were not affected. Milk protein concentration tended (P = 0.15) to be higher for the zeolite total mixed ration (TMR). Ruminal pH tended to increase (P = 0.11) by feeding the sodium bicarbonate or the zeolite. A second lactation experiment ...


Integration Of Nutrition Education Classes Into English As Second Language Classes For Refugees, Sarah Gunnell May 2012

Integration Of Nutrition Education Classes Into English As Second Language Classes For Refugees, Sarah Gunnell

All Graduate Theses and Dissertations

Recently resettled refugees are at high risk for food insecurity and its health consequences. This observational study evaluated the effectiveness of integrating nutrition lessons into English as a Second Language (ESL) classes at a work-site training center for refugees. The lessons focused on making healthy choices with a limited budget. Through the assistance of ESL teachers, nutrition educator assistants (NEAs) from the Supplemental Nutrition Assistance Program (SNAP) taught nutrition lessons to 98 refugees from 17 different countries for 12 weeks. Food frequency questionnaires (FFQ) for 49 participants were matched pre and post 12 weeks of class. A Wilcoxon test was ...


Effects Of Soluble Calcium-To-Protein Ratio On Age Gelation Of Ultra, Je Hong Ryue May 1994

Effects Of Soluble Calcium-To-Protein Ratio On Age Gelation Of Ultra, Je Hong Ryue

All Graduate Theses and Dissertations

Reverse osmosis (RO) and ultrafiltration (UF) retentates were ultra-high temperature (UHT) processed and compared for storage life at room temperature. Viscosity studies indicated that UHT-treated, RO retentate delayed age gelation longer than UF retentate at the same total solids level (26% TS). When compared at 6.4% protein level (2x RO vs 2.7x UF where x=ratio of the feed volume to concentrate volume), the storage life for both RO and UF retentates was about 6 to 8 months.

Sodium hexametaphosphate (SHMP) and disodium phosphate (DSP) at 1, 3, 5, 10, and 20 mM concentrations were incorporated prior to ...
