Algal Growth And Decomposition: Effects On Water Quality, Edward G. Foree, John S. Tapp Jr.

KWRRI Research Reports

The chemical composition of algae grown in batch culture depends mainly on environmental conditions, nutrient availability, presence of predators, cell age, and species. The effects of nutrient availability and cell age on the composition of three unialgal cultures (algae + bacteria) and one hetergeneous culture (algae + bacteria + microscopic animals) were evaluated. The cultures were grown in batch culture under both nutrient-abundant and nutrient deficient conditions and the changes in compositions were observed. Luxurious uptake where nutrients are incorporated into cellular protoplasm at levels greater than those necessary for growth, and super-luxurious uptake, where some nutrients are stored rather …

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 …
