Vocalizations Of Isolated Piglets. Ii. Some Environmental Factors, D. Fraser

Communication Skills Collection

The vocalizations of suckling piglets were studied during brief tests which involved social isolation, restriction of movement, and exposure to unfamiliar surroundings. Similar trends were shown in most cases by the three classes of call studied - closed mouth grunts, open mouth grunts, and squeals. The rate of calling was much lower when a piglet was in the home pen than when alone in an unfamiliar pen, and more calls were given in both situations when the animal’s movement was restricted by caging. The presence of the dam and four littermates in unfamiliar surroundings caused a large reduction in calling, …

Additional Records Of The Stenodermine Bat, Sturnina Thomasi, From The Lesser Antillean Island Of Guadeloupe, Hugh H. Genoways, J. Knox Jones

University of Nebraska State Museum: Mammalogy Papers

Sturnira thomusi was named and described by de la Torre and Schwartz (Proceedings of the Biological Society of Washington 79: 297-303, 1966) on the basis of a single male from the island of Guadeloupe, Lesser Antilles, that was captured by Richard Thomas in 1963. The holotype of S. thomasi has until now been the only known specimen of this unique species. In late July of 1974, a field party from the Museum of Texas Tech University (supported by a grant from the National Science Foundation, GB-41105) collected bats on Guadeloupe and took four additional individuals of S. thomasi, all …

Injectable Famphur For Control Of Grubs In Cattle, P. H. Kohler, R. N. Gates, L. B. Embry, L. B. Embry

South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1975

Grubs are a major pest of cattle and cause considerable economic loss to the cattle industry. Running of cattle and standing in available water sources during heel fly strikes no doubt are reflected in lighter weaning weights of claves because of reduced grazing time and cows becoming separated from their calves. Other losses to producers and feeders include possible reduced feedlot performance by grub infested animals, weight loss and down grading of carcasses that are trimmed to remove areas damaged by grubs and a lower value for hides due to grub holes. Several effective products and methods of treatment are …

Energy Level In Ration, Market Weight And Types Of Cattle, L. B. Embry, W. J. Costello, W. S. Swan

South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1975

The effect of body size on feed efficiency has been the subject of research for several years. Evidence was presented from some of the early research that body weight is unrelated to feed efficiency. Recent research has also shown that current recommended net energy requirements, such as those by the National Research Council, for growing and finishing beef cattle are valid for various sizes and types of beef animals. Large-bodied cattle gaining at a faster rate require more feed and should be fed ro heavier weights to reach best market grade.

Marketing Margins For Beef And Related Considerations, Bruce A. Ginn

South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1975

In an environment where inflation has become a way of life, rising prices are a natural accomplice. High prices are fine--for the seller. But those of us who wear the hat of the consumer (and that's all of us) greet escalating costs with a less than joyful attitude. The question is, Can consumers, longshoremen, producers, shippers, and the Russians find happiness together? In some respects the interests of the producer and the consumer may not be significantly different and could form the basis of an alliance in which marketing innovations could take place.

Soybean Meal Or Urea During Feedlot Adaptation And Growing Of Calves, R. N. Gates, L. B. Embry

South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1975

This experiment investigated the response by calves to different levels of protein during the first four weeks of feedlot adaptation using soybean meal, urea or a combination of the two sources. Following the adaptation period, the calves were continued on experiment for a growing phase to compare soybean meal and urea as supplements to corn silage.

Acid-Treated Vs. Dried Corn With And Without Zeranol Implants For Finishing Cattle, L. B. Embry, R. C. Ward

South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1975

Corn grain is frequently harvested at a moisture content too high for safe keeping under conventional grain storage conditions. While this may be a desirable or necessary practice, the grain must be dried, stored under oxygen-limiting conditions, stored to produce ensiled grain or treated with an effective preservative to prevent spoilage during storage. Each of these methods is being used for preservation and storage of corn when harvested at a high-moisture content (20 to 30%) and used for feeding livestock. Total costs including storage structures, losses in processing and storage and comparative feeding value are factors involved in choice of …

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

Direct comparisons between DES, zeranol and Synovex implants and a non-implanted control under various conditions and are more limited. In the experiment reported here, implants of the three products were compared to a nonimplanted control when steers were fed finishing rations with and without roughage.

How Energy Level In Ration, Market Weight And Type Of Cattle Influence Beef Carcass Traits, W. J. Costello, L. B. Embry, W. S. Swan

South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1975

An experiment reported in this publication under the title "Energy Level in Ration, Market Weight and Types of Cattle" provided material to observe the influence of the three factors listed on beef carcass characteristics. Details describing the cattle, rations and market weights are presented in that report.

Factors Affecting The Cattle Industry Outlook Situation, Gene E. Murra

South Dakota Cattle Feeders Field Day Proceedings and Research Reports, 1975

Historically, many of the demand and supply relationships which impact on the cattle industry in the United States and South Dakota have been rather easy to analyze. This is not true today--many of the old, simple relationships have become complex. The purpose of this paper will be to present some of the demand and supply relationships as they pertain to outlook.

Vocalizations Of Isolated Piglets. I. Sources Of Variation And Relationships Among Measures, D. Fraser

Communication Skills Collection

The vocalizations and activity of suckling piglets aged 4 to 25 days were studied during 5-min periods of social isolation in an unfamiliar enclosure. The animals became very active and vocalized repeatedly during the test, but the reaction was attenuated among older litters. Calls were predominantly closed mouth grunts at low rates of calling, and mainly squeals and open mouth grunts at high overall rates. Squealing correlated with open mouth grunting and with the activity measure both within and between litters. Even so, the measures appeared to be affected independently by the piglets’ behaviour in the home pen just before …

Spinturnicid Mites Of Venezuela (Acarina: Spinturnicidae), C. Selby Herrin, Vernon J. Tipton

Brigham Young University Science Bulletin, Biological Series

The results of an extensive survey of spinturnicid mites of bats from Venezuela are presented in this paper. Approximately 30,000 bats were collected from a wide variety of life zones and localities. A representative sample was searched for ectoparasites. There are 3 genera of the family Spinturnicidae in Venezuela: Cameronieta, Periglischrus, and Spinturnix. Three previously described species of Cameronieta were found in the Venezuelan collection. Of the 7 species of Spinturnix previously described from the New World, 4 are reported from Venezuela. The genus Periglischrus constitutes by far the most significant segment of the Venezuelan collection. It is represented by …

Distribution And Abundance Of The Black-Billed Magpie (Pica Pica) In North America, Carl E. Bock, Larry W. Lepthien

Great Basin Naturalist

Analysis of Audubon Society Christmas bird count data and certain environmental variables shows the degree to which the Black-billed Magpie is a bird of cool arid regions in North America. The abundance and distribution of this species appear to be limited by two major climatic barriers: increasing summer temperatures in the Southwest and increasing summer humidity and precipitation on the central plains.

The Effect Of Altitude On Thyroid Function Of The Uinta Ground Squirrel (Citellus Armatus), Wendell Lee Wells

Theses and Dissertations

Thyroid uptake and distribution of 125I, concentrations of T4 and T3 in serum and thyroids and concentrations of TSH in serum and pituitaries were measured to determine thyroid function of Uinta Ground Squirrels (Citellus armatus) native to 5,400 and 9,000 feet elevations to evaluate alterations in the state of the thyroid due to increased altitude. Uptake of 125I was 60 percent lower by squirrels from 9,000 feet. Incorporation of 125I into T3 was greater at the higher elevation, but absolute thyroid T3 concentrations were similar at both elevations. No significant differences were found in serum T3 concentrations, but squirrels living …
