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)...

The effect of various additives on nutritive value of ryegrass straw silage

Creator:: Shultz, Thomas Anthony
Abstract:: Observations were made on silage pH, chemical composition and 24hr in vitro dry matter digestion (IVDMD) to evaluate effects of various additives ensiled with annual ryegrass straw. Additives were compared in factorial designed trials utilizing .95 1 glass jar silos. Selection of additives used in each subsequent trial was based...

The effects of aerobic and anaerobic fermentation on the nutritive value of ryegrass straw

Creator:: Jones, Steven Ryan
Abstract:: A series of in vitro laboratory trials and in vivo sheep digestion trials were used to evaluate aerobically or anaerobically fermented perennial ryegrass straw. The laboratory trials consisted of a silage study, where mini-silos were used in a 9 X 2 factorial design with nine levels of whey (0 to...

Effect of prepartum anionic supplementation on periparturient feed intake and behavior, health and milk production

Creator:: DeGroot, Michael Alan
Abstract:: Our objectives were to determine if dietary cation-anion difference (DCAD) and source of anions influence periparturient feed intake and milk production, and to characterize feeding behavior of dairy cattle during the transition period. Diets differed in DCAD (cationic or anionic) and anionic supplement (BioChlor®, Fermenten®, or anionic salts), and were...

Effects of two forms of intrareticular selenium supplements on beef cow selenium status and on the transfer of selenium from dam to offspring

Creator:: Campbell, Donald T.
Abstract:: Two concurrent studies were conducted to evaluate the effect of selenium (Se) supplementation on beef cows. Trial 1 was designed to evaluate the safety and efficacy of two intrareticular Se supplementation delivery systems. Trial 2 was designed to evaluate the transfer of Se across the placenta and through the colostrum...

Comparison of high and low tannin sorghum grain with low quality roughage for feeding ruminants

Creator:: Wanyama, Justin Mukami
Abstract:: Two studies were conducted to compare lamb feedlot performance and digestibility of nutrients by lambs fed rations containing bird-resistant and bird-susceptible sorghum grain with 20 or 40% tall fescue hay as a source of roughage. Four rations were fed ad libitum on the performance study and at 80% of ad...

Comparison of Canine Spermatozoa Motility, Morphology, and RNA Integrity Using Three Different Cell Purification Solutions

Creator:: Hegedus, Rachel M.
Abstract:: Transcriptome gene expression studies of sperm RNA have been utilized in a variety of different species to investigate causes of male infertility. Previous research investigators have optimized cell separation and RNA isolation techniques for each species of interest. To date, no study has been completed for dogs. The objective of...

Influence of protein supplementation frequency on cows consuming low-quality forage : performance, grazing behavior, and variation in supplement intake

Creator:: Schauer, Christopher Scott
Abstract:: Our objective was to determine the influence of CP supplementation frequency (SF) on cow performance, grazing time, distance traveled, maximum distance from water, cow distribution, DMI, DM digestibility, harvest efficiency (HE), percentage of supplementation events frequented, and CV for supplement intake for cows grazing low-quality forage. One hundred-twenty pregnant (approx....
