Estradiol Interactions With Dopamine Antagonists In Mares: Prolactin Secretion And Reproductive Traits, Kristian Kandis Kelley Jan 2006

Estradiol Interactions With Dopamine Antagonists In Mares: Prolactin Secretion And Reproductive Traits, Kristian Kandis Kelley

LSU Master's Theses

Two experiments studied the effects of pretreatment with estradiol benzoate before treatment with a dopamine antagonist on prolactin secretion and reproductive traits in mares during 1) the seasonal anovulatory period and 2) the normal breeding season. Experiment 1 was performed in winter with 17 mares selected for low follicular activity. Nine mares received estradiol benzoate injections every other day for a total of 10 injections; 8 mares received similar injections of vehicle. Ten days after onset of injections, all mares were placed on a daily injections of sulpiride (250 mg) for 45 d or until ovulation. Plasma prolactin concentrations were …

A System For Wintering Beef Heifers Using Dried Distillers Grains, Leslie Aaron Stalker, Don C. Adams, Terry J. Klopfenstein Jan 2006

A System For Wintering Beef Heifers Using Dried Distillers Grains, Leslie Aaron Stalker, Don C. Adams, Terry J. Klopfenstein

Nebraska Beef Cattle Reports

A two-year experiment compared two systems for wintering pregnant heifers. The standard system used by the ranch served as the control (CON) and the treatment system (TRT) included a dried distillers grains based supplement. Heifers in the TRT system were heavier and had greater body condition score at end of supplementation. Calving difficulty, percentage of live calves weaned and subsequent pregnancy rate were similar between systems. Calves born to heifers in the TRT system were heavier at birth and weaning. The TRT system cost $10.47/heifer less than the CON system and resulted in equivalent or improved heifer and calf growth …

Feeding Melengestrol Acetate To Bulls Prior To And At Puberty Alters Body Weight, And Hormone Concentration, April Tefler, Ryann Mcfee, Rebecca C. Bott, Joseph Schulz, Debra T. Clopton, Jeffrey W. Bergman, Karl V. Moline, Kathy Hanford, Andrea S. Cupp Jan 2006

Feeding Melengestrol Acetate To Bulls Prior To And At Puberty Alters Body Weight, And Hormone Concentration, April Tefler, Ryann Mcfee, Rebecca C. Bott, Joseph Schulz, Debra T. Clopton, Jeffrey W. Bergman, Karl V. Moline, Kathy Hanford, Andrea S. Cupp

Nebraska Beef Cattle Reports

Melengestrol acetate (MGA), which is commonly used in the beef industry to manipulate ovarian activity of females, was fed to bulls at two times during development, prepubertal (5.5 to 7.5 months) and peri-pubertal (6.5 to 9.5 months), to determine effects on testes size, scrotal circumference, body weight, and/or hormone production. We can conclude that feeding bulls MGA during the prepubertal and peri-pubertal time can alter body weight and testosterone production.

Digestibility Of Undegradable Intake Protein Of Feedstuffs, Joshua R. Benton, James C. Macdonald, Galen E. Erickson, Terry J. Klopfenstein, Don C. Adams Jan 2006

Digestibility Of Undegradable Intake Protein Of Feedstuffs, Joshua R. Benton, James C. Macdonald, Galen E. Erickson, Terry J. Klopfenstein, Don C. Adams

Nebraska Beef Cattle Reports

Digestibility of undegradable intake protein of subirrigated meadows, upland native range, smooth bromegrass, and other feedstuffs used in several growing trials was measured using the mobile nylon bag technique. In general, as the grazing season progressed, undegradable intake protein (UIP) digestibility of grazed forages decreased. Also, UIP digestibility was highly variable among feedstuffs. Compared to the constant 80% digestibility of UIP used by the 1996 Beef NRC, grazed and harvested forages tend to have much lower UIP digestibility values while the supplemental protein sources evaluated tend to have higher UIP digestibility values.

Economic Optimum Use Of Wet Distillers Grains In Feedlots, Kyle J. Vander Pol, Galen E. Erickson, Terry J. Klopfenstein, Darrell R. Mark Jan 2006

Economic Optimum Use Of Wet Distillers Grains In Feedlots, Kyle J. Vander Pol, Galen E. Erickson, Terry J. Klopfenstein, Darrell R. Mark

Nebraska Beef Cattle Reports

An economic analysis was conducted using feedlot performance, current feed ingredient prices, trucking, and cost of feeding inputs to determine economics of feeding wet distillers grains plus solubles (WDGS) at five dietary inclusions. The analysis also incorporated positive corn basis into the model. Cattle returns are greatest when incorporated WDGS is fed at 30 to 40% of DM at feedlots located between 0 and 60 miles from the plant. As distance of the feedlot increases from 60 to 100 miles from the plant, optimum inclusion is between 20 and 30% of dietary DM. Either a 5 or 10 cent positive …

Growth Promoting Agents And Season Effects On Blood Metabolite And Body Temperature Measures, Terry L. Mader, Wanda Kreikemeier Jan 2006

Growth Promoting Agents And Season Effects On Blood Metabolite And Body Temperature Measures, Terry L. Mader, Wanda Kreikemeier

Nebraska Beef Cattle Reports

To assess growth promoting agents efficacy among seasons, triiodothyronine, thyroxine, blood metabolites, and tympanic temperature were measured in summer and winter studies. Within each season, pens of heifers were assigned to one of six growth promotant treatments. Season by growth promotant treatment interactions (P < 0.05) indicated that the combination of estrogen and trenbolone acetate increased triiodothyronine in the winter, whereas trenbolone acetate alone decreased both triiodothyronine and thyroxine in the winter. Maximum tympanic temperature was greater (P < 0.01) in the summer than in the winter, while minimum tympanic temperature was lowered (P < 0.01) in the summer. Changes in blood metabolite levels resulting from the use of growth promotants do not appear to substantially influence seasonal changes in body temperature.

Inhibition Of Methanogenesis In Rumen Fluid Cultures, Eric Behlke, Razvan Dumitru, Stephen Ragsdale, James M. Takacs, Jess L. Miner Jan 2006

Inhibition Of Methanogenesis In Rumen Fluid Cultures, Eric Behlke, Razvan Dumitru, Stephen Ragsdale, James M. Takacs, Jess L. Miner

Nebraska Beef Cattle Reports

We identified 32 compounds that inhibit 13 to 100% of the methane produced by in vitro cultures of rumen fluid and have the potential to inhibit enteric methanogenesis in ruminant animals. The compounds are analogous to a substrate in the methane biosynthesis pathway, and may inhibit methane production yet not affect other organisms in the rumen.

Livestock Risk Protection Insurance Vs. Futures Hedging: Basis Risk Implications, Rik R. Smith, Darrell R. Mark, Allen L. Prosch Jan 2006

Livestock Risk Protection Insurance Vs. Futures Hedging: Basis Risk Implications, Rik R. Smith, Darrell R. Mark, Allen L. Prosch

Nebraska Beef Cattle Reports

This study analyzes the benefit of Livestock Risk Protection (LRP) insurance to cattle producers in reducing basis risk. Nebraska producers insuring fed cattle with LRP realize a basis risk reduction of one-third to one-half compared to futures or options hedging. Nebraska feeder cattle producers using LRP experience only a slight reduction in basis risk. Reduced basis risk results in smaller errors when forecasting basis levels for future time periods. With more accurate basis forecasts, producers can better estimate net hedged selling prices and, consequently, future cash flows.

The Influence Of Cooking Rate And Holding Time On Beef Flavor, Jennie M. James, Chris R. Calkins Jan 2006

The Influence Of Cooking Rate And Holding Time On Beef Flavor, Jennie M. James, Chris R. Calkins

Nebraska Beef Cattle Reports

Seven muscles from 10 beef carcasses were cooked quickly or slowly and held 0 or 1 hour to explore the influence of cooking rate and holding time on beef flavor. Off-flavor intensity was lowest when beef was cooked slowly (on a 300°F grill instead of a 480°F grill) and when it was held for 1 hour prior to sensory evaluation. The infraspinatus (flat iron) had the least intense off-flavor and the vastus intermedius (knuckle bottom) had the most intense off-flavor. Slow cooking or holding for 1 hour prior to consumption reduced the intensity of off-flavor in value cuts.

Wet Distillers Grains Plus Solubles Do Not Increase Liver-Like Off-Flavors In Cooked Beef, Blaine Jenschke, Jennie James, Kyle Vander Pol, Chris R. Calkins, Terry J. Klopfenstein Jan 2006

Wet Distillers Grains Plus Solubles Do Not Increase Liver-Like Off-Flavors In Cooked Beef, Blaine Jenschke, Jennie James, Kyle Vander Pol, Chris R. Calkins, Terry J. Klopfenstein

Nebraska Beef Cattle Reports

Crossbred steers fed with varying levels of wet distillers grains to test the incidence of liver-like off-flavors. USDA Choice steaks, when compared to USDA Select, had significantly higher trained sensory muscle fiber tenderness scores, less detectable connective tissue, higher juiciness scores, and more intense off-flavor ratings. USDA Choice steaks had a higher percentage of panelists denote liver-like and metallic off-flavors. Wet distillers grains did not significantly influence off-flavor indicating these by-products can be used to finish cattle without causing detrimental effects on the sensory profile.
