Activity Of A Dipodomys Ordii Population Using Recapture Methods, James R. Garcia

Theses and Dissertations

Activity curves for Dipodomys ordii were developed from data obtained from a study utilizing an electrically monitored trapping grid. The curves for non-perturbated populations showed an initial post-dusk peak, followed by increasing activity and a large pre-dawn peak; but after ten dominant animals had been removed, the largest activity peak was post-dusk. Differences in activity patterns were not found among sex, age or reproductive classes. Rising ambient temperatures, falling barometric pressures, winds over 3.2 km/hr and the absence of the moon depressed capture numbers; while increasing humidity (relative and absolute), decreasing soil temperatures at 20 and 40 cm below ground …

The Effects Of Highway Construction On The Fish Populations In The Weber River Near Henefer, Summit County, Utah, Edward James Peters

Theses and Dissertations

Alterations of streams to facilitate highway construction and consumptive water use has become a fisheries management problem. To evaluate the effects of channeling concomitant to construction of Interstate 80 N. near Henefer, Utah, altered and unaltered sections of the Weber River were compared on the basis of fishes censused, population estimates and ordinations. Species compositions in particular areas were influenced by local rheologic conditions. Changes in species composition between samplings at a particular area were caused by fish movements. Data from altered sections, rehabilitated with deflectors and checkdams, were not noticeably different than data from unaltered areas. However, fish movements …

Diethylstilbestrol, Zeranol Or Synovex-S Implants For Growing Steers, L. B. Embry, W. S. Swan

South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1974

Numerous experiments during the past several years have shown that implanting feedlot steers or heifers with diethylstilbestrol (DES), zeranol or Synovex results in an increase in rate of gain with improved feed efficiency. Comparisons between the three products under various conditions are more limited. Therefore, comparative effects of DES, zeranol and Synovex-S were tested in a growing experiment where steers were full-fed corn silage with 2 lb. per head daily of protein supplement for a period of about 3 months.

Effects Of Monensin On Feedlot Performance Of Growing And Finishing Steers, L. B. Embry, W. S. Swan

South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1974

Feed additives have become an important part of rations for feedlot cattle during the past several years. They have been shown to being about improved performance in various ways such as stimulating growth, favorable alterations in fermentative and synthetic activity of the digestive tract and improvement in general health of the animals allowing more efficienct absorption and utilization of nutrients consumed.

Pine Sawdust As A Roughage Substitute In Beef Finishing Rations, L. D. Kamstra

South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1974

Previous reports discussed toxicity trials with untreated sawdust, indicating no toxicity to ruminants when fed up to 25% of the ration. The low digestibility (7-10%) of softwood sawdust produced from the mills in western South Dakota limits its usage as a major ration component. The objective of this experiment is to demonstrate the usage of ponderosa pine (Pinus ponderosa) sawdust as a nonnutritive roughage component in beef finishing rations.

Quality Measurement Of Hay Stored By Large Hay Packaging Systems, L. D. Kamstra, R. Schrempp, P. Turnquist, C. Johnson

South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1974

The purpose of this study was to determine to what extent large hay package storage retained the initial forage quality by measurement of seven quality parameters over an extended period. The Hesston 60 and Haybuster 1800 were used as examples of hay packaging systems for study.

Soybean Meal And Urea Supplements With Corn Silage At Various Stages Of Feeding For Growing Cattle, L. B. Embry, W. S. Swan

South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1974

Calves weaned and fed supplements containing urea generally have a period of reduced performance in comparison to those fed soybean meal supplements. The period of reduced gains may last for 3 to 4 weeks for calves unapted to urea, but it may vary in legnth and severity depending upon the level of urea, energy concentration of the diet, age of cattle and stresses to which subjected prior to arrival and at the feedlot. The period of reduced performance appears to become of lesser importance with increasing age of the cattle.

Protein Supplementation For Finishing Cattle Fed All-Concentrate Or Low Roughage (Alfalfa) Diets, L. B. Embry, W. S. Swan

South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1974

The experiment reported here was conducted to determine the need for supplemental protein in all-concentrate diets composed largely of corn grain and in diets with low levels of roughage (4 lb. of alfalfa haylage). Cattle fed supplements with soybean meal or urea were compared to those fed similar diets without supplemental protein to the corn or corn and alfalfa haylage.

Waterfowl Portraits, Paul A. Johnsgard

Papers in Ornithology

SINCE HIS days as a boy on the North Dakota prairies, Paul A. Johnsgard has "measured his winters, not by conventional time units, but in the days it took for the snow geese to return from their wintering grounds...." The author of five books: Song of the North Wind-A Story of the Snow Goose; Grouse and Quails of North America; Waterfowl- Their Biology and Natural History; Animal Behavior; and Handbook of Waterfowl Behavior, and of numerous articles in national magazines and over 40 technical papers, he is eminently qualified to capture in pen and ink the very essence of Nebraska's …

The Relative Attenuation Of Self-Stimulation, Eating And Drinking Produced By Dopamine-Receptor Blockade, E. T. Rolls, B. J. Rolls, P. H. Kelly, S. G. Shaw, R. J. Wood, Robert H.I. Dale

Scholarship and Professional Work - LAS

Spiroperidol, which blocks dopamine (DA) receptors, attenuated self-stimulation of the nucleus accumbens, septal area, hippocampus, anterior hypothalamus and ventral tegmental area. Dopamine is thus involved in self-stimulation of many sites (in addition to the lateral hypothalamus). The attenuation was not a simple motor impairment of the speed of bar-pressing in that the nucleus accumbens and septal self-stimulation rates were lower than those in treated animals self-stimulating at other sites (Experiment 1). Feeding was partly attenuated, and drinking was much less attenuated by the spiroperidol. Since the rats bar-pressed for brain- stimulation reward, chewed pellets to eat, and licked a tube …

Biology Of Northern Bald Eagles (Haliaeetus Leucocephalus Alascanus) On Amchitka Island, Alaska, Steven K. Sherrod

Theses and Dissertations

Bald Eagles on Amchitka Island, Alaska, were studied from 1969-1972. From 1970-1972 the population averaged 214.6 eagles. The average ration was 66% adults to 34% subadults. The eagles move to and from the island in relation to significant food sources (especially the garbage dump). An increase in active nests occurred from 1969-1972 due to an increase in food. The average percentage of nests containing young from 1970-1972 was 71.28%. During these three years, the average number of young known in a nest per nesting attempt was 1.24, and the average number of young known in a nest per nest containing …

Eutamias Minimus And E. Amoenus: Morphological Cluster Analysis, Sandra Elaine Anderson

Dissertations and Theses

Cluster analysis of a large body of data on 180 Oregon specimens of Eutamias minimus and E. amoenus suggest that overall length of skull, basal length of skull and length of palate are taxonomically critical. If their sum is less than 71.3 millimeters the animal is E. minimus. If the sum is greater than 72.7 millimeters the animal is E. amoenus. If the sum is between 71.3 and 72.7 millimeters, other factors must be considered before the animal can be identified. Of the 180 specimens, there were 60 E. minimus, 114 E. amoenus, 2 hybrids, 2 …

The Spatial Distribution Of The Nests Of The Black-Crowned Night Heron (Nycticorax Nycticorax) And The Snowy Egret (Leucophoyx Thula) In Central Utah, Randall S. Isham

Theses and Dissertations

Nests of the Black-crowned Night Heron and the Snowy Egret were examined in five central Utah colonies in 1973 to determine the spatial distribution within the colony. Nest locations of the 1085 nests of the two species were plotted to the nearest foot with an alidade and plane table. Tests of randomness, clump size, association, segregation, and T distribution were utilized. No differences between species were noted for the distance to the nearest and the next nearest nest. The Night Heron nested closer to other Night Herons and more often than did the Snowy Egret which non-significantly selected either species …

Structural And Operational Characteristics Of Nebraska And Kansas Feeder-Cattle Growing Operations, J. L. Jorgensen, J. G. Kendrick, A. C. Wellman, J. H. Mccoy, J. W. Koudele, Q. C. Smith

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The beef cattle industry is experiencing a significant increase in demand for feeder cattle. Current difficulties in obtaining sufficient numbers of feeder cattle on a continuing basis have put pressures on the feeder cattle marketing system that did not exist in the past. Feedlot operators, growers (backgrounders), and cow-herd operators are looking for ways and means of improving the system. Innovations are being tested. Those circumstances prompted personnel of the Agricultural Experiment Stations of Kansas and Nebraska to undertake a joint study of cattle marketing under a Regional Research Project.
