Influence of subclinical hypocalcemia on plasma biochemical parameters, liver histologic changes, and common postpartum diseases in dairy cows
(University of Missouri--Columbia, 2011)
.001). Hypocalcemic cows had lower plasma phosphorus concentrations on days 0 (P = 0.002), 7 (P = 0.05), 14 (P = 0.03), and 21 (P = 0.04). Hypocalcemic cows had higher NEFA concentrations on days 0 (P = 0.01) and 21 (P = 0.02). Hypocalcemic cows also tended to have...
The effects of supplemental anionic salts & yeast culture on the production of dairy cattle during the periparturient period
(University of Missouri--Columbia, 2006)
The objective of this thesis was to determine nutritional strategies with the strategic use of feed additives during the periparturient period to reduce the negative energy balance as the dairy cow transitions from late ...
Genetic and nutritional effects on reproduction in lactating dairy cows
(University of Missouri--Columbia, 2020)
Good reproductive performance is a prerequisite for profitable pasture-based seasonal calving systems of milk production. The objective of this dissertation was to elucidate the physiological mechanisms contributing to ...
Effects of heat stress on leukocyte function and gene expression in lactating dairy cows
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The effects of heat stress in animal agriculture are expected to become more serious as global temperatures continue to increase. Negative effects on production, reproduction...
Using metabolic and biochemical characteristics of postmortem muscle to investigate the interconnectedness of beef color, flavor, and tenderness
(University of Missouri--Columbia, 2021)
Understanding relationships between beef palatability and quality components are crucial for continued production of high quality and consistent beef products. Myoglobin concentrations at 48 and 336 h resulted in moderate, ...
