Analyzing The Correlation Between Overall Likeness And Emotional Responses Before And After The Consumption Of Dairy Beverages, Jessica L. Weber

Dairy Science

In today’s food industry there is a need for more research on the correlation between likeness of a product and what kind of emotional response this may lead to. This has potential to allow the food industry to understand consumer purchase intent and use the data collected from specific studies to gain more insight to repeat purchases. The objectives of this study were to understand more about the relationship between overall likeness of dairy beverage products from initial taste to ending taste as well as how these responses related to the emotional responses of the consumption experience. In two geographical …

The Relationship Between Rumination And Milk Yield In Early Lactating Holsteins And Jerseys, Jason Borges

Dairy Science

The objective of this study is to determine if there is a direct relationship between rumination and energy corrected milk produced, using a technologic rumination tracking system. This technology is better known as AI24™ and is produced by Micro Dairy Logic: Advanced Dairy Solutions and SCR™, but marketed through Semex. The collar system is able to track rumination, aid in diagnosing illness/injury, predict parturition, and detect estrus in cows. The sophisticated electronic tag monitors a cow’s rumination time, chewing rhythm and time between feed boluses to determine how many minutes per day the cow is ruminating. Each collar is equipped …

Genomic Testing And Method R Variance Components Theory Of Dairy Cattle, Joseph Dewey Coleman

Dairy Science

Abstract

The objective of this study is to determine the change in reliability from non genomic evaluations or Parent Averages to genomic evaluations. Due to recent industry popularity of genomic evaluations the California Polytechnic University, San Luis Obispo, decided to participate in the genetic movement of the dairy cattle industry. Genomic evaluations of both Holstein and Jersey cows at the Cal Poly dairy were chosen based on genetic superiority in order to possibly generate more income for the dairy and increase the herd’s popularity. Leading genomic companies such as Pfizer Animal Health, and GenSeek made genomic evaluation of the Cal …

Potential For Barn Owl As Rodent Biological Control In Central California Vineyards, Hannah Tillmann

Biological Sciences

The pocket gopher (Thomomys bottae) and voles (Microtus spp.) cause significant economic damage to vineyards. In response, many growers have taken steps to attract Barn Owls (Tyto alba) to their properties to help keep these rodent populations in check. This research project investigated Barn Owl consumption of pocket gophers and voles in Central California vineyards in order to assess the efficiency of this integrated pest management strategy. I collected a total of 715 owl pellets from five vineyard locations in Templeton and Paso Robles, California over an eight-month period during nesting and post-fledging seasons. I …

Nebraska Bird Review

Fifteen counts, one more than last year, were held during the period, and a total of 139 species, 10 fewer than last year, were found. This was a count season of record totals for the state for a number of species. Factors contributing to this include the number of counts, the number of participants and the weather. More counts (15) were run than in any previous year, and several counts (Lake McConaughy in particular) had a much greater than average number of participants. The weather prior to the count period was mild, and most of the circles had unusually warm …

Report Of A Nesting Sora (Porzana Carolina), William M. Lemburg, Wayne J. Mollhoff

Nebraska Bird Review

During the summer of 2008, long-time NOU member and former NOU Treasurer William (Bill) Lemburg of Cairo, Howard Co., Nebraska, discovered the nest of a Sora (Porzana carolina). On 29 July 2008, while using a small flat-bottomed boat to gather duckweed (Spirodela polyrhiza) on a small pond near his bird pens to feed the exotic waterfowl he raises, he noted a pair of Sora walking about, foraging atop the dense growth of duckweed. The pair ignored his presence even though, as he later discovered, he was within 10 feet of their nest. The following evening, 30 …

Use Of A Complete-Feed Diet (Ramp) To Rapidly Transition Cattle To A Finishing Diet, C. J. Schneider, Brandon L. Nuttelman, Dirk Burken, Terry J. Klopfenstein, Galen E. Erickson

Department of Animal Science: Faculty Publications

A study evaluated transitioning cattle from RAMP to a finishing diet with fewer intermediate step diets and days fed during transition. Yearling crossbred steers (n = 390; BW = 341 ± 14 kg) were blocked and stratified by BW, and assigned randomly within strata to 40 feedlot pens, with 9 or 10 steers per pen. Treatments were different grain adaptation programs (27 or 28 d) involving blends of RAMP and finishing diet. A control adaptation program involved decreasing RAMP and increasing a 62.5% corn finishing diet (62.5% high moisture corn (HMC), 25% sweet bran, 7.5% alfalfa hay (AH), and 5% …

Anaerobic Digestion Of Finishing Cattle Manure With And Without Distillers Grains In The Diet., Andrea K. Watson, Terry J. Klopfenstein, Galen E. Erickson, Samodha C. Fernando, Jana L. Harding, Adam L. Shreck

Department of Animal Science: Faculty Publications

Two treatments (cattle diet) were used in anaerobic digestion of finishing cattle manure. Diet 1 contained 82.5% dry rolled corn (DRC) (CONT) and diet 2 contained 40% wet distillers grains plus solubles (DM basis) replacing DRC (WDGS). Cattle were housed in stanchions for 3 d with complete manure collection in a cement pit. Manure (feces and urine) was sampled and analyzed for minerals, DM and OM. Manure collected was weighed into individual allotments based on DM and frozen. Continuously stirred anaerobic digesters (n = 7, 1 L capacity) were inoculated and maintained for 5 mo before the trial to ensure …

Causes Of Pneumonia Epizootics Among Bighorn Sheep, Western United States, 2008–2010, Thomas E. Besser, Margaret A. Highland, Katherine Baker, E. Frances Cassirer, Neil J. Anderson, Jennifer M. Ramsey, Kristen Mansfield, Darren L. Bruning, Peregrine Wolff, Joshua B. Smith, Jonathan A. Jenks

Natural Resource Management Faculty Publications

Epizootic pneumonia of bighorn sheep is a devastating disease of uncertain etiology. To help clarify the etiology, we used culture and culture-independent methods to compare the prevalence of the bacterial respiratory pathogens Mannheimia haemolytica, Bibersteinia trehalosi, Pasteurella multocida, and Mycoplasma ovipneumoniae in lung tissue from 44 bighorn sheep from herds affected by 8 outbreaks in the western United States. M. ovipneumoniae, the only agent detected at signifi cantly higher prevalence in animals from outbreaks (95%) than in animals from unaffected healthy populations (0%), was the most consistently detected agent and the only agent that exhibited single strain types within each …

Spatial Ecology Of White-Tailed Deer Fawns In The Northern Great Plains: Implications Of Loss Of Conservation Reserve Program Grasslands, Troy W. Grovenburg, Robert W. Klaver, Jonathan A. Jenks

Natural Resource Management Faculty Publications

Few studies have evaluated how wildlife, and white-tailed deer (Odocoileus virginianus) in particular, respond to Conservation Reserve Program (CRP) grasslands. We conducted a 3-year study (2007– 2009) to determine the influence of CRP on fawn ecology during a time of declining CRP enrollment. We captured and radiocollared 81 fawn white-tailed deer during 15 May to 15 June 2007–2009 in north-central South Dakota, collected 6,505 locations, and documented 70 summer home ranges. Mean summer home ranges increased temporally during 2007–2009 (P < 0.001) and corresponded to a 41% loss of CRP grasslands in the area (2.3% loss in land cover and approx. 21% loss in cover habitat in the study area) over the duration of the study. Additionally, mean movement between daily locations increased (P < 0.001) from 2007 to 2009. Analysis of covariance models indicated that change in CRP influenced home-range size, and change in CRP and wheat influenced daily movement. Smaller home ranges and reduced movements were associated with greater quantity of CRP available to fawns, and increased movements were associated with more acreage of wheat available to fawns. Fawns shifted resource selection during the summer at a mean age ranging from 48.8 days to 58.6 days, and this shift was associated with height of corn (83–87 cm). During early summer, fawns consistently selected for CRP; selection of wheat progressed temporally from avoidance in 2007 to selection in 2009. During late summer, fawns consistently selected for corn habitat and used CRP at least in proportion to its availability. Reduction in CRP-grasslands seemed to increase fawn home-range size and daily movements and, influenced change in resource selection to wheat. Current legislation mandates continued decrease in CRP enrollment and concomitant increase in the planting of corn for ethanol production. Management of habitat throughout the grasslands of the Northern Great Plains that maximizes cover habitats would provide neonates with adequate cover for protection from predators.

Winter Field Report, December 2011 To February 2012, W. Ross Silcock

Nebraska Bird Review

The most obvious feature of this winter’s avian movements was the number of Snowy Owls, unprecedented in living memory, that invaded the state. A tally maintained by Joel Jorgensen and Lauren Dinan of Nebraska Game and Parks indicated that over 200 snowies were found in the state, and most were documented. Not as popular with the public, but perhaps of greater scientific interest were the mid-winter reports of species normally rare at this time of year. Most notable in this respect were waterfowl, grebes, cranes, and sparrows. A read-through of these species suggests the very mild winter experienced over most …

It seems to me, in view of all the concerted efforts of our state's elective officers to enact a set of morals for every Nebraskan to live by - especially relative to marriage and reproduction - they could take a lesson from prairie dogs, rather than passing a law requiring the poisoning of entire colonies at the whim of an unhappy neighbor. ...

Isotopic Niche Differentiation Among Mammals From A Rainforest In Peninsular Malaysia, Kae Kawanishi, Song Horng Neo Liang, Chris T. Darimont, Thomas E. Reimchen, Melvin E. Sunquist

Biochemistry Collection

We performed stable isotope analysis on eight mammalian species: pig-tailed macaque (Macaca nemestrina), long-tailed macaque (M. fascicularis), dusky leaf monkey (Trachypithecus obscurus), brush-tailed porcupine (Atherurus macrourus), wild boar (Sus scrofa), lesser mouse-deer (Tragulus javanicus), greater mouse-deer (T. napu), and barking deer (Muntiacus muntjac), to test the hypothesis that the differences in diet and habitat types among species, guilds and foraging strategies are reflected in the δ¹⁵N and δ¹³C signatures of their tissues. Whereas the isotopic ratios differed among taxa, the four major isotopic groups observed were: mouse-deer species, primate species, brush-tailed porcupine, and wild boar. The …
