Autoradiographic Localization Of Serotonin And 5-Hydroxytryptophan In The Rat Brain, Gordon Keith Matheson

Theses and Dissertations

Serotonin is a normal constituent of the brain and has been claimed to act as a neurohormonal or regulatory agent in nerve transmission. Previous workers have only studied its whole brain or subcellular particulate distribution. Because the brain itself is divided into many distinct ganglia and nuclei, the distribution of serotonin in these sites is considered to be of greater importance than either the whole brain or subcellular distribution. This paper is a study of the distribution of serotonin in particular brain sites in rats with normal and elevated levels of the amine, with and without electroshock treatment. The results …

Estimates Of Heritability Of Beef Cattle Performance Traits By Regression Of Offspring On Sire, C. J. Brown, Maximo Gacula

Genetics Collection

Data used in this study were taken from performance test records of Hereford, Aberdeen-Angus and Shorthorn sires and their progeny that were raised and performance tested at the Arkansas Agricultural Experiment Station during the years 1951 through 1962. Heritability estimates based on regression of offspring on sire were obtained from 201 male progeny belonging to 20 sire groups. The estimates obtained were 0.19±0.19 for 120-day weight, 0.27±0.13 for initial test weight, 0.93±0.18 for test daily gain, 0.43± 0.18 for feed consumption, 0.41±0.25 for feed conversion, 0.15±0.15 for type score, 0.37± 0.14 for final test weight, and 0.79±0.18 for production index.

Coccidiosis Of Cattle, Datus M. Hammod

Faculty Honor Lectures

The disease known as coccidiosis occurs in many domestic and wild animals. It is of great importance in chickens, in which coccidiosis is one of the chief causes of losses to the producer. In cattle the disease was estimated by Fitzgerald in 1962' to cause an . annual loss of $3,500,000 in calves under one year of age in the 11 western states and $7,500,000 in the seven west north-central states. In making this estimate Fitzgerald calculated that 90 percent of all calves are infected by coccidia, and that the average loss amounted to 75 cents per head on all …

Heritability In Relation To Selection Differential In Cattle, G. E. Bradford, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

The concept of heritability as generally used, involves the assumption that additive genetic variance is a constant proportion of total variance over the entire range of phenotypes. If this assumption holds, selection response will be linearly related to selection differential. If not, prediction of selection response will not be possible from a knowledge of the phenotypic selection differential and the average proportion of additive genetic variance. Thus the validity of this assumption has a bearing on the design of efficient selection schemes for many situations. In the field of applied animal breeding, for example, this will affect such important questions …

The Relative Accuracy Of Estimating The Production Of Dairy Cows As Affected By Length Of Testing Interval And Method Of Estimating Production, Ross M. Young

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Production records for dairy cows were first based on the yield of butter for a seven day period any time during the lactation. Later, 365- day records based on production for one day in each calendar month came into general use. The records preferred at present are 305- day records based on monthly test day production, but calculated using the centering date method. The centering date estimate is based on milk and butterfat production from two consecutive milkings per month. The sampling day is centered as nearly as possible in the test month period which need not coincide with the …

Canada Goose Production And Population Stability, Ogden Bay Waterfowl Management Area, Utah, Norman H. Dey

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Since the development of Ogden Bay Waterfowl Management Area in 1937, the Canada goose (Branta canadesis moffitti) population increased to a peak in 1949 and then declined slightly. Nelson (1954) noted that the decrease in population was probably due to either a change in habitat or increased hunting pressure. In recent years, direct band returns have indicated a high mortality rate in the population. This project was initiated to determine the relative stability of the Canada goose population and to measure, as closely as possible, the effect of a high mortality rate upon the nesting population.
