Effects Of Imposed Feed Intake Variation On Acidosis And Performance Of Finishing Steers, R. J. Cooper, Terry J. Klopfenstein, Rick Stock, C. T. Milton, D. W. Herold, J. C. Parrott Jan 1999

Effects Of Imposed Feed Intake Variation On Acidosis And Performance Of Finishing Steers, R. J. Cooper, Terry J. Klopfenstein, Rick Stock, C. T. Milton, D. W. Herold, J. C. Parrott

Department of Animal Science: Faculty Publications

Four metabolism and two finishing trials were conducted to determine the effects of imposed feed intake variation on acidosis and performance of finishing steers. In Metabolism Trial 1, four ruminally fistulated steers were limit-fed and subjected to either a constant amount of feed per day (C) or low intake variation of .7 kg/d (LV). No treatment differences were found for intake or measures of acidosis. Metabolism Trial 2 was conducted similarly to Metabolism Trial 1 with treatments of C and high intake variation of 1.4 kg/d (HV). Treatment HV increased ( P < .05) acidosis, as indicated by the area of ruminal pH below 5.6. In Metabolism Trial 3, four steers were fed at ad libitum levels of intake and subjected to three levels of intake variation: ad libitum intake with no imposed intake variation (AL), LV of .7 kg/d, and HV of 1.4 kg/d. No treatment differences were found. In Metabolism Trial 4, six ruminally fistulated steers were fed at ad libitum levels and subjected to three levels of intake variation: AL, LV of .9 kg/d, and HV of 1.8 kg/d. Average ruminal pH increased ( P < .05) and area of ruminal pH below 5.6 decreased ( P < .05) as level of intake variation was increased. In Finishing Trial 1, 75 steers were assigned to eight pens and two treatments: AL or HV of 1.8 kg/d. Dry matter intake increased ( P < .05) from AL to HV. Daily gain and gain/feed were not affected by treatment. In Finishing Trial 2, 94 steers were assigned to 12 pens and two treatments: AL or HV of 1.8 kg/d. No treatment differences were noted in DMI, daily gain, or gain/ feed. Therefore, results of these trials indicate that intake variation of up to 1.8 kg/d does not increase acidosis or decrease performance of finishing steers fed at ad libitum levels of intake.

Effects Of Backgrounding And Growing Programs On Beef Carcass Quality And Yield, Terry J. Klopfenstein, R. Cooper, D. J. Jordon, D. Shain, T. Milton, Chris R. Calkins, C. Rossi Jan 1999

Effects Of Backgrounding And Growing Programs On Beef Carcass Quality And Yield, Terry J. Klopfenstein, R. Cooper, D. J. Jordon, D. Shain, T. Milton, Chris R. Calkins, C. Rossi

Department of Animal Science: Faculty Publications

Clearly, the future of the beef cattle industry in the United States depends on the quality of the product. The majority of calves are born in the spring; therefore, to have a consistent supply of feeders entering feedlots and to take advantage of forages, a variety of stocker programs exist. Cattle enter the feedlot at varying weights and ages and from different nutritional backgrounds, and this variation could produce differences in carcass quality. The economically important measures of carcass quality are yield grade and quality grade. They are directly related: as cattle fatten in the feedlot, both quality grade and …

Estrous Synchronization For Beef Cattle, Gene H. Deutscher Jan 1999

Estrous Synchronization For Beef Cattle, Gene H. Deutscher

Department of Animal Science: Faculty Publications

This Fact Sheet discusses the potential benefits of estrous synchronization, how the products and programs work, and the results and costs involved.

Estrous (heat) synchronization is a management practice that can help beef producers improve production efficiency and economic returns. It can help shorten the breeding and calving seasons and help increase calf weaning weights. Its purpose is to control estrous and ovulation in cycling females, so that breeding can be completed in a short period of time. Instead of females being bred over a 21-day period, synchronization can shorten the breeding period to less than five days, depending on …

Estimation Of Direct, Maternal, And Grandmaternal Genetic Effects For Weaning Weight In Several Breeds Of Beef Cattle, J. Dodenhoff, L. Dale Van Vleck, K. E. Gregory Jan 1999

Estimation Of Direct, Maternal, And Grandmaternal Genetic Effects For Weaning Weight In Several Breeds Of Beef Cattle, J. Dodenhoff, L. Dale Van Vleck, K. E. Gregory

Department of Animal Science: Faculty Publications

Weaning weights from nine parental breeds and three composites were analyzed to estimate variance due to grandmaternal genetic effects and to compare estimates for variance due to maternal genetic effects from two different models. Number of observations ranged from 794 to 3,465 per population. Number of animals in the pedigree file ranged from 1,244 to 4,326 per population. Two single-trait animal models were used to obtain estimates of covariance components by REML using an average information method. Model 1 included random direct and maternal genetic, permanent maternal environmental, and residual environmental effects as well as fixed sex ´ year and …

Estimates Of Direct, Maternal And Grandmaternal Genetic Effects For Growth Traits In Gobra Cattle, M. Diop, J. Dodenhoff, L. Dale Van Vleck Jan 1999

Estimates Of Direct, Maternal And Grandmaternal Genetic Effects For Growth Traits In Gobra Cattle, M. Diop, J. Dodenhoff, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

Estimates of genetic parameters for birth (N = 3909), weaning (N = 3425), yearling (N = 2764) and final (N = 2144) weights were obtained from the records of Gobra cattle collected at the Centre de Recherches Zootechniques de Dahra, Senegal. Three animal models were fitted to obtain estimates by REML using an average information (AI) approach. Model 1 considered random direct, maternal genetic and maternal permanent environmental effects. In model 2, a general grandmaternal effect was added to the random effects considered in model 1, and in model 3, the general grandmaternal effect was divided into grandmaternal genetic and …

High Frequency Ultrasonic Characterization Of Carrot Cell Texture, Christopher Vick Jan 1999

High Frequency Ultrasonic Characterization Of Carrot Cell Texture, Christopher Vick

Theses

Ultrasound offers a versatile imaging modality. It has a long history of medical use, but system and signal processing limitations have limited its full range of capabilities. By examining other uses of ultrasound, such as materials testing, the effectiveness of medical ultrasound tissue identification could likely be improved. To a limited degree, low frequency ultrasound has been used examine the texture of carrots tissue. These studies focused on the velocity and attenuation of low frequency ultrasound through a carrot sample; these results yielded a degree of ambiguity when attempting to identify a carrot texture. In our research, we attempted to …

Reevaluating The Forum Non Conveniens Doctrine In Multiterritorial Copyright Infringement Cases, Brenda Tiffany Dieck Jan 1999

Reevaluating The Forum Non Conveniens Doctrine In Multiterritorial Copyright Infringement Cases, Brenda Tiffany Dieck

Washington Law Review

The tension between the internationalization of copyright and the territorial remedies national laws provide is illustrated when the same infringer infringes a copyright in multiple countries. The copyright owner can bring suit in each country separately or attempt to consolidate all claims into one forum. Commentators have identified that in consolidated suits, even if jurisdiction over the foreign claims is proper, the discretionary forum non conveniens doctrine rmains a "wild card." This Comment explores in greater depth why the doctrine is unpredictable and argues that it is being abused by U.S. federal courts in multiterritorial copyright suits, exacerbating the problem …

Clinostomum Marginatum (Yellow Grub) Metacercaris In Black Bass From The Caddo River In West Arkansas, James J. Daly Jr., H. Michael Matthews, Randal J. Keller, James J. Daly Jan 1999

Clinostomum Marginatum (Yellow Grub) Metacercaris In Black Bass From The Caddo River In West Arkansas, James J. Daly Jr., H. Michael Matthews, Randal J. Keller, James J. Daly

Journal of the Arkansas Academy of Science

Seventy-two bass (Micropterus-spp.), mostly smallmouth, were collected from three areas of the Caddo River in west Arkansas and examined for the presence of Clinostomum marginatum metacercariae. Prevalence, mean abundance, and abundance for all fish were 68%, and 4.2 ±6.5, and 30, respectively. Fish from the upstream area near the headwaters were more heavily infested than those from further downstream. A gill/total body larval ratio of seven, was found for bass from another Arkansas stream, was examined as a predictor for total Clinostomum populations instream bass. Using the formula gill parasites X seven divided by N(72), a value of 3.3 was …

Arkansas Gray Fox Fur Price-Harvest Model Revisited, Peta Elsken-Lacy, Amy M. Wilson, Gary A. Heidt, James H. Peck Jan 1999

Arkansas Gray Fox Fur Price-Harvest Model Revisited, Peta Elsken-Lacy, Amy M. Wilson, Gary A. Heidt, James H. Peck

Journal of the Arkansas Academy of Science

Peck and Heidt (1985) proposed a linear model that demonstrated that for gray fox (Urocyon cinereoargenteus) in Arkansas; total fur harvests from 1966-1982 were highly correlated with mean pelt values. Single variable models using linear regression analysis of current season pelt values (CSPV) and previous season pelt values (PSPV) were designed to predict total fur harvests. These models demonstrated high correlations (r =0.93 and 0.89, respectively). In the past 15 years, markets for fur have undergone many perturbations within Arkansas and overseas resulting in great changes in mean pelt prices. In an attempt to evaluate the continued performance of the …

Effects Of Varied Intensity Resistance Training In Combination With Extra Mass-Bearing Exercise On Bone Adaptations In Ovariectomized And Sham Operated Sprague Dawley Rats, Donna Quimby, Kathy Hall Jan 1999

Effects Of Varied Intensity Resistance Training In Combination With Extra Mass-Bearing Exercise On Bone Adaptations In Ovariectomized And Sham Operated Sprague Dawley Rats, Donna Quimby, Kathy Hall

Journal of the Arkansas Academy of Science

This experiment was designed to study the effects of intensity of exercise on bone adaptations in ovariectomized and sham operated 12 week old rats. Eighty Sprague Dawley rats were divided by mass into two equal groups (mean = 197 g). One group was ovariectomized (OVX); the other sham (S) operated. Each surgery group was then subdivided by mass into four exercise intensity groups. The exercise intensity groups were created by loading additional mass (percent of animals body mass, 0%, 3%, 6% and 9%) on each animal in combination with treadmill running (10 m/min.; 30 min./day; 4 days/wk.; for 7 weeks). …

Status Of Three Plethodontid Salamanders (Genus Plethodon) From The Ouachita National Forest Of Southwest Arkansas, Stanley E. Trauth, J. D. Wilhide Jan 1999

Status Of Three Plethodontid Salamanders (Genus Plethodon) From The Ouachita National Forest Of Southwest Arkansas, Stanley E. Trauth, J. D. Wilhide

Journal of the Arkansas Academy of Science

A three-year field investigation was initiated in 1996 to update previous information on the local abundance and distribution of three salamanders of the genus Plethodon (P. caddoensis, P.fourchensis, and P. ouachitae); these salamanders are found within a five-county area of the Ouachita National Forest in southwestern Arkansas. Plethodon fourchensis was most numerous at three sites in Polk County; a total of 18 specimens was found. Searching for Plethodon fourchensis was successful following moderate-to-heavy precipitation but only in selected habitats on Fourche and Irons Forks mountains. The preferred habitats of P. caddoensis were talus-covered slopes and wet ravines consisting of mostly …

Morphology And Electrophysiology Of Retinal Photoreceptor Terminations In The Octopus (Eledone Cirrosa) Optic Lobe, Dominic Anthony Hussey Jan 1999

Morphology And Electrophysiology Of Retinal Photoreceptor Terminations In The Octopus (Eledone Cirrosa) Optic Lobe, Dominic Anthony Hussey

School of Biological and Marine Sciences Theses

Cephalopods possess a well-developed visual system encompassing a pair of camera-type eyes attached to specific visual processing regions of the central nervous system known as the optic lobes. The retina contains a single type of photoreceptive cell, which send axons via a dorso-ventral chiasma to the optic lobes. Although electrophysiological recordings have been routinely obtained from the retina there are few recordings from the optic lobe. This study investigated the morphology and electrophysiology of the first synapse in the Octopus (Eledone cirrosa) visual system. The morphology and innervation patterns of individual optic nerves onto the optic lobe were revealed using …
