Some Observations On Ecto- And Endoparasites Of Chiroptera, John E. Ubelaker

Fondren Science Series

The various groups of organisms associated with bats have caught the interest of many investigators. Noteworthy is the review by Stiles and Nolan (1931) in which all known parasites of bats were listed. Allen (1939) presented a general introduction to the parasites of bats in which he emphasized the arthropods. Other references to parasites of bats are concerned with particular groups. In this paper I hope to acquaint the reader with these groups and to indicate some of the interesting relationships that have been elucidated. The tremendous number of papers published concerning organisms associated with bats precludes the inclusion of …

Caste Regulation In The Termite, Neotermes Jouteli (Banks), Richard David Nagin

Student Theses and Dissertations

The southern Florida termite Neotermes jouteli (Kalotermitidae) was found to provide exceptionally suitable material for the study of caste regulation, with special reference to the regeneration of reproductive forms. It was possible to collect entire natural colonies of this termite, including the reproductive pair, and to maintain them for long periods in the laboratory. In this way the characteristics of individual colonies could be studied in a way not done in most earlier work on caste regulation. Most interesting was the finding that the capacity to regenerate lost reproductive forms was a characteristic of individual colonies. By removing groups of …

High Pre-Mating Liveweights Improve The Lambing Performance Of Merino Ewes, R J. Suiter

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

Analysis of lambing trials with Merino ewes has shown a highly significant association between pre-mating liveweight and lambing performance.

With May-June lambing ewes there was a 2.9 per cent, lambing increase for every extra 10 lb. liveweight; for July-August- September lambing ewes there was a 6.9 per cent, increase for every 10 lb. liveweight increase.

With the May-June lambing there was a critical weight below which twinning was negligible.

Maintaining Ewe Bodyweight For A Late Mating, T Marshall

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

DEPARTMENT OF AGRICULTURE experiments have indicated that the bodyweight of ewes at mating can have a large bearing on lambing performance.

It appears that for every 10 lb. increase in pre-mating bodyweight, an increase of some 3 to 6 per cent, lambs born could be expected, depending on the lambing time.

Effects Of Mastitis On Milk Yield And Composition, Department Of Agriculture, Western Australia

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

EVERY DAIRY farmer knows how much he spends on the treatment of cows affected with mastitis, but the actual loss in production is more difficult to estimate.

As part of the current mastitis research programme the Department of Agriculture's Animal and Dairying Divisions surveyed 37 dairy herds with a believed high incidence of mastitis.

1970 Nebraska Beef Cattle Report, J. L. Adams, E. F. Frolik, H. W. Ottoson, F. E. Eldridge

Nebraska Beef Cattle Reports

The use of high concentrate rations in finishing cattle has led to a rather high loss of livers due to abscesses.

The 1967 Statistical Summary of the Federal Meat Inspection Service of the USDA indicated the total number of cattle inspected was 27,859,980. Of these, 9.6% were condemned because of liver abscess. Considering the value of a liver to be about $3, the estimated loss to the industry because of condemnatIon due to abscess would be over $8 million annually.

The incidence of liver abscesses increases as the roughage level in a finishing ration decreases below 5% (Table I). The …

The Enterobacteriaceae: A Preliminary Study Of New Methods Of Identification: Rapid Biochemical Testing And Salt Tolerance, William F. Brooks Jr.

MUSC Theses and Dissertations

Commercially available reagent-impregnated paper strip tests and tablet substrate tests were evaluated in comparison to the standard biochemical tests using representative members of the Enterobacteriaceae. For the most part, these tests were found to be unreliable or difficult to interpret. Standard media for key biochemical tests were then modified and a new inoculation procedure developed to allow for test results after four hours incubation. Representative members of the Enterobacteriaceae were tested using the modified standard media and, where a given test was critical for the differentiation of the organisms, the rapid test results were in complete agreement with the control …

Later Mating Improves Lambing Results, R J. Suiter

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

Ovulation studies in Western Australia have indicated that increased lambing percentages in crossbred and Merino ewes could be expected from mating in February-April rather than December- January.

Such increases have been demonstrated in time of lambing trials with crossbred ewes, but had not been seen in Merino flocks until recently.

This report summarises the results of time of lambing trials with Merinos carried out at the Merredin and Wongan Hills Research Stations between 1963 and 1969.

Emergency Chlorination Of Farm Water Supplies, H C. Hughes

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

TOWARDS the end of summer (and especially in a drought) the risk of water in dams, soaks, wells or tanks becoming polluted is increased.

Bore water is much less likely to be affected unless the bore is poorly sited near a farm building, such as a shearing or milking shed, a pig pen, or a septic tank system.

Causes Of Low Lambing Percentages, Department Of Agriculture, Western Australia

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

West Australian Merino flocks average about 70 per cent, lambs marked each year. Reasons for this low percentage are that as many as 30 per cent, of ewes do not lamb, twinning rates are low and from 10 to 25 per cent, of lambs born die.

Among the research projects by the Department of Agriculture's Sheep and Wool Branch have been a number directed at the various stages of reproduction in the ewe. These have given some important leads on the causes of low lambing percentages.

If you have marked less than 60 per cent, lambs in the past several …

Lupins In Western Australia. 5. The Grazing Value Of Green And Mature Lupins, John Sylvester Gladstones

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

WHETHER or not lupins are grown primarily as a grain crop, grazing of standing crops and harvested stubbles will continue to be an important use. This article examines the uses of sweet lupins for forage, and the main problem of lupin grazing, lupinosis.

Flavor Preference And Stability Of A Low-Fat Dairy Spread, James Robert Miller

Electronic Theses and Dissertations

Low-fat dairy spread has been defined as a product which contains only dairy ingredients and has a lower fat content than the commonly used spreads, butter and margarine (5). Although some low-fat spreads have contained very little fat, most of those which have been developed during the past 30 years have contained about one-third to two-thirds as much fat as the commonly used spreads and have had a higher protein content. ·The low-fat dairy spread studied in this project contained about ten times more protein and only one-half as much fat as butter and margarine. The present day justification of …

Abnormal Milk Evaluations In Eastern South Dakota Milk Plants And Dairy Herds, Edwin J. Kleen

Electronic Theses and Dissertations

For many years bovine mastitis has been a major problem for dairy producers, the seriousness of which can be measured by the volumes of literature which have been written about it as well as the economic losses incurred by the dairy industry because of it. The fact that mastitis is still a virulent disease in spite of the vast amount of research conducted on it would suggest either that the underlying causes of mastitis still are not completely understood or that the knowledge gained through research has not been presented effectively to those who need it most—namely the dairy farmer. …

Echolocation And Communication In Bats, Edwin Gould

Fondren Science Series

Bat echolocation studies date back to 1793 when Lazaro Spallanzani investigated the effects of blinding and deafening bats. He blinded wild bats and several days after the operation found that they had survived and had insect-laden stomachs. The deafened bats, on the other hand, collided with obstacles in a darkened or lighted room (Dijkgraaf, 1960). Griffin & Galambos (1940, 1941 and 1942) as well as Dijkgraaf (1943, 1946) repeated some of Spallanzani's experiments. They concluded that bats emit high frequency sounds, the echos of which are used for obstacle avoidance. Two essential kinds of observations supported the echolocation hypothesis: bats …

Chiropteran Mortality, David D. Gillette, John D. Kimbrough

Fondren Science Series

The study of chiropteran mortality is a difficult one because observations concerning mass mortality, predation, and fatal accidents are sporadic and unexpected. Almost every known predaceous animal preys on bats from time to time; but (with one or two rare exceptions) do so only when an occasional opportunity presents itself, and do not specialize in bat predation. Our knowledge of bat pathology is meager. Mass-mortalities have been reported only from sight observations, and the causative organisms rarely ascertained, because of the unexpected encounter. The relationships between human and chiropteran diseases are becoming much better understood; this study is mostly oriented …

Bats: Carriers Of Human Disease-Producing Agents, Robert J. Baker

Fondren Science Series

For many years bats have been known to be harbingers of various agents which produce disease in man. Elsewhere in this volume certain parasites of bats are discussed including the association of these animals with Trypanosoma cruzi in South America and Texas (Ubelaker, 1970). Little is known concerning the association of bats with bacteria which cause disease in man. Four serotypes of Salmonella known to cause salmonellosis have been isolated from bats, one from bats collected in the Canal Zone (Klite & Kourany, 1965) and the other three from bats collected in southwestern Colombia, South America (Arata et al., 1968). …

Bat Conservation, Edwin Gould

Fondren Science Series

Since we know that some bat populations attain astronomical size, bat conservation may seem inconsequential. However, during the past 10 to 20 years, some bat-banders and other mammalogists have reported a decrease of bats in hibernating cave colonies. In general, summer colonies of most species of bats are dispersed; from these sites migrating bats converge on relatively few caves in which they hibernate. Some species are probably most vulnerable in at least the following four situations. 1. Hibernating bats that roost in caves or mines may be destroyed by teenagers or adults who have no concern for the bats. 2. …

Effect Of Days Open On Lactation Production, Roger L. Ripley

Electronic Theses and Dissertations

Accurate evaluation of dairy production records is essential if dairymen are to establish and maintain profitable dairy herds and efficient culling programs. Improper record evaluation may result in. saving breeding stock that otherwise might be eliminated. Many factors may influence the validity of individual production records. Adjustment factors, currently in use by the United States Department of Agriculture (USDA) for sire and cow evaluations, are generally accepted as removing the majority of these influences. Consequently, these factors are invaluable to practical dairymen. The adjustment factors, suggested by McDaniel, et al. (24) in 1967, take into account the geographical location, season …

Some Ecological Relations Of Fairy Shrimps In Alkaline Habitats Of Nebraska, D. B. Mccarraher

Nebraska Game and Parks Commission: Staff Research Publications

Ecological studies on the distribution of fairy shrimps have been made from 246 sites in the sandhills region of Nebraska. New records for Nebraska have been established for Artemia salina, Branchinecta campestris, B. lindahli, B. mackini and Cyzicus mexicanus. Seasonal populations of shrimp have been located in habitats containing permanent fish populations. Water mineralization was the dominant environmental condition related to the distribution of phyllopods with sodium and potassium compounds predominating in the strongly alkaline lakes. Several of the Artemia lakes were classified as hydroxide sites. Many of the alkaline ponds, where B. lindahli and B. campestris flourish, are …
