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

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

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

Department of Animal Science: Faculty Publications

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 …

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.

Seasonal Investigation Of Native Fishes And Their Habitats In Missouri River And Yellowstone River Backwaters, Shannon J. Fisher

Electronic Theses and Dissertations

Interactions between the Missouri River and its floodplain have been severely degraded due to channelization and impoundment. Ecologists have assumed that backwaters are a critical habitat component for certain life stages of native fishes; however, documented relationships are limited. During this study, I monitored fishes, invertebrates, and habitats to help determine the importance of backwaters to native fishes of various life stages, and to assess the changes that occur in habitat characteristics and invertebrate densities during periods with differential connectivity. Seven assemblages of fishes, identified with catch-per-unit-effort data, had at least some relationship with the backwaters. The assemblages included two …
