Antigenic Relationships In Seven Strains Of Tetrahymena, W.E. Engelhard, B.W. Mccashland

Papers in Microbiology

Tetrahymena, along with other genera of the family Frontoniidae, have been the subject of many scientific investigations concerning problems in protozoan physiology. Unfortunately in many instances, difficulty arises when attempting to identify properly the form that was used in the particular study. Until rather recently, relatively little had been accomplished by way of a comprehensive study of the interrelated genera, and of these very few have dealt with taxonomic problems serologically.

Dairy Calves Can Safely Be Fed Once A Day, R A. Bettenay

Journal of the Department of Agriculture, Western Australia, Series 4

THE sale of milk rather than butterfat has increased greatly in the past few years and less than half the dairy farmers in Western Australia now own cream separators.

Feeding whole milk once a day can be successful for raising dairy calves, even in winter when calf rearing is most difficult.

A recent experiment at Wokalup Research Station showed that satisfactory weight gains can be achieved if liquid milk is fed only once a day from a very early age. Trial calves gained I lb a head a day over the 12 weeks of the experiment.

Once-a-day feeding greatly reduces …

Infectious Sinusitis Of Turkeys, J Edgar

Journal of the Department of Agriculture, Western Australia, Series 4

Climatic conditions in W.A. are ideal for turkey production if advantage is taken of the wide open spaces. Over-crowded, poorly ventilated quarters are ideal for the spread of infectious sinusitis, and the disease, once established, is hard to eliminate without a complete change of birds.

This article provides advice for the prevention of this important disease at a time when turkey raising is increasing in W.A.

Responses Of Rumen Microflora To Whey Products Added To High-Grain Low-Roughage Rations, Virgil L. Metzger

Electronic Theses and Dissertations

Many factors present in livestock feeds affect the numbers and types of protozoa and bacteria in the rumen. A small particle size of feed and a fast rate of passage of the feed through the ruminant decreases protozoal numbers. Full feeding of a concentrate ration and an acid pH in the rumen also tend to reduce protozoa numbers. Bacteria numbers tend to increase as the protozoa numbers decrease. Knowledge of rumen microflora population changes on different rations is lacking. It is known that restricted-roughage rations will generally cause lower protozoal numbers. Since whey is an available source of lactose and …

Some Ecological Effects Of The Oil Industry On Farmland In East Central Illinois, Dale E. Fruendt

Masters Theses

Between June, 1970 and July, 1971 a two square mile area in East Central Illinois served as a study area for the effects of the oil industry on farm land. Observations were made on several farms concerning the activity of oil companies and interviews with farmers were held. Two areas of farmland were given special attention. One was a clover field where salt water had flooded a portion of the field. The other area was a corn field where oil had flooded approximately eight acres of land. Random samples of invertebrates were taken in both of these areas as well …

Industrial Pollution In Coles County, Illinois, Michael William Conlin

Masters Theses

The Anaconda American Brass Company at Mattoon, Coles County, Illinois was found to discharge waste containing excessive amounts of copper, hexavalent chromium, sulfates, acids, and alkalies. These wastes were found to enter an agricultural field tile system and to emit at the Shellhammer tile where they entered a small unnamed creek, a large pond along Interstate 57, and Riley Creek.

Tests of the Shellhammer tile and Anaconda American Brass Company effluent were conducted from March, 1970 thru May, 1971. Maximum concentrations determined were as follows: (1) copper -- 15.5 ppm; (2) hexavalent chromium -- 1.5 ppm; (3) pH -- range …

Micronutrients And Biological Patterns In Lake Mead, Hasan K. Qashu, Lorne G. Everett, J. S. Carlson, Bureau Of Reclamation

Publications (WR)

Progressive increases in concentration of dissolved solids in the Colorado River water from Lake Powell to Imperial Dam seem to alter plankton dynamics and biological productivity of the river. Also, changes in biological productivity and micronutrients concentrations occur within the same reservoir. Development of a digital simulation model to predict micronutrients concentrations and biological productivity is necessary for diagnosing changes in plankton population and effluent-carrying capacity of the system. The objectives of the study are: (1) to determine trace metal balance at different locations in Lake Mead, (2) to measure biological productivity and conduct plankton population counts at each sampling …

The Effect Of Las Vegas Wash Effluent Upon The Water Quality In Lake Mead, D. A. Hoffman, P. R. Tramutt, F. C. Heller, Bureau Of Reclamation

Publications (WR)

This study developed from observations made during an earlier study on Lake Mead which was reported in CHE-70, Water Quality Study of Lake Mead. Results from that study indicated that poor-quality water was flowing into the Las Vegas Bay reach of Boulder Basin, Lake Mead. Also reports of deteriorating water quality, resulting in taste and odors in domestic water supplies taken from Boulder Basin as well as a reduction in the attractiveness of Las Vegas Bay for recreational uses caused by aquatic plants and algae blooms, indicated a need for a concentrated study concerning the effects of flows from Las …

Some Biological Aspects Of Lizard Eimerians, With A Description Of Eimeria Poinsettis N. Sp. From Sceloporus Poinsetti, David A, Colwell

All Master's Theses

A previously described eimerian, Eimeria sceloporis, from the northwestern fence lizard, Sceloporus occidentalis occidentalis, was observed for oocyst production, incidence and intensity of infection in both juvenile and adult lizards. In order to test the species specificity of Eimeria ahtanumensis, an attempted transmission was made to Sceloporus poinsetti, Sceloporus jarrovi, Sceloporus undulatus and Sceloporus occidentalis. During the winter of 1970-1971 fecal samples were collected from Sceloporus poinsetti to determine possible coccidial infections. The lizards were collected in September of 1970 in Hidulgo County, New Mexico and the ensuing investigation showed that nine of the thirteen adults were passing an intestinal …

Effects Of Feeding Leptaden To Dairy Cows, Sitakantha Dash

Electronic Theses and Dissertations

Leptaden is a herbal drug which was recently introduced to the market by Alarsin Pharmaceuticals, Bombay, India. It consists of the extracts of two indigenous medical plants, namely Leotadenia reticulata (Jeevanti) and Breynia patens (Kamboji) in equal proportions. In 1947, Patel first drew the attention of gynaecologists to the usefulness of Leptaden in habitual abortions and allied conditions in women and later on pointed out its lactogenic and galactagogue properties. His original observations are supported by growing clinical experience over a twenty year period of medical practice. Published clinical experience shows that in most cases Leptaden stimulates, lactation within twelve …

Discovery Of The Carolina Marsh Clam, Polymesoda Caroliniana (Bosc), A Supposed Florida Disjunct Species, In Everglades National Park, Florida, D.C. Tabb, D.R. Moore

Gulf and Caribbean Research

The presence of disjunct species of animals on either side of the Florida peninsula has been reported by a number of authors. The littorinid mollusk, Littorina irrorata Say, which has a range from Massachusetts to the Rio Grande of Texas, except for south Florida, is one such species (Bequaert 1943). The marsh crab, Sesarma cinereum (Bosc), is another example of an animal with a distribution from Virginia to the western Gulf of Campeche except for a break in southern Florida (Rathbun, 1918). Williams (1965) lists 23 species of crustaceans having interrupted distribution at the Florida peninsula. This report on discovery …

Pre-Impoundment Limnological Study Of The Strawberry River In Northeastern Arkansas, Henry W. Robison, George L. Harp

Journal of the Arkansas Academy of Science

A study of pre-impoundment limnological characteristics of the Strawberry River was made from August, 1967 to June, 1968. Two collecting stations were established, one upstream which would not be inundated and a lower station which would be inundated when impoundment was complete. The Strawberry River was characterized by high alkalinity and pH, low carbon dioxide and turbidity, and adequate oxygen values. Plankton was characterized by limited numbers of Staurastrum, Gomphonema, and Rotatoria. Pool-riffle communities were ill-defined. Chironomidae, Oligochaeta and Ephemeroptera were dominant pool macroinvertebrates among 13 taxa collected. Of the 20 taxa collected in riffles Trichoptera, Ephemeroptera, Simuliidae and Chironomidae …

Ichthyofaunal Diversification And Distribution In The Big Creek Watershed, Craighead And Greene Counties, Arkansas, James T. Jenkins, George L. Harp

Journal of the Arkansas Academy of Science

Big Creek is a relatively small deltaic stream, in northeastern Arkansas, in an area of intense cultivation. Recently it has been dredged in the interest of flood control. Lost Creek and Mud Creek are the major tributaries of Big Creek and collectively drain the Big Creek watershed. The streams were found to have relatively low alkalinity, moderate carbon dioxide, adequate oxygen values, and relatively high turbidity. Channeling of Big Creek and Lost Creek has effectively destroyed distinct pool-riffle biocies and reduced the number of acceptable spawning areas. Lost Creek, also, receives effluent from residential dwellings, a secondary treatment sewage plant, …
