Worms In Sheep. 2. Seasonal Variations In Worm Burdens, R W. Butler

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

The first article in this series described the worms which commonly infest sheep in Western Australia and the symptoms caused by heavy infestations.

This article outlines the effects of seasonal changes on worm burdens in sheep.

AS a basis for planning a worm control programme it is essential to have information on the seasonal changes in worm burdens and on the factors which control these.

In this article, the more important of these are considered.

Poison Plants Of Western Australia : The Toxic Species Of The Genera Gastrolobium And Oxylobium. 1. Characteristics Of The Group, T E H Aplin

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

THE toxic species of the genera Gastrolobium and Oxylobium are a unique group of poison plants which have caused considerable economic loss to stock-raisers in Western Australia ever since the early days of settlement.

These plants are widely distributed over the agricultural areas of the south-west, and, with the opening up of large tracts of land for stock-raising, the danger is as high as it has even been.

These Worms ........ Caused This, F C. Wilkinson

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

THE weather had been remarkably pleasant, with an odd shower of rain followed by several warm days.

Just the weather for blowfly troubles, so the owner decided it was time he crutched his breeding flock of 500 ewes.

But as the mob approached the yards trouble was coming

A Guide To Good Lamb Marking, H E. Fels

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

LAMB marking is the most severe of the various ordeals that sheep are called upon to endure.

It is a series of surgical operations, each involving a risk of infection, and some involving risks of severe haemorrhage.

Growth rate is reduced to the same extent by rubber rings as by the knife.

1967 Beef Cattle Progress Report Of Research Activities, E. F. Frolik, H. W. Ottoson, J. L. Adams

Nebraska Beef Cattle Reports

Oral feeding of stilbestrol or implanting with stilbestrol or Synovex has resulted in increased weight gain and efficiency of gain for cattle fed finishing rations.

Combining oral feeding or stilbestrol with implanting did not give increased performance above that obtained from oral stilbestrol alone in two tests. Implanting cattle fed oral stilbestrol at the start of the feeding program with either stilbestrol or Synovex gave a similar pattern of performance to that obtained from oral stilbestrol alone.

A New Species Of Rhinoceros, Aphelops Kimballensis, From The Latest Pliocene Of Nebraska, Lloyd G. Tanner

Bulletin of the University of Nebraska State Museum (1924–2023)

An uncrushed skull and associated skeletal elements of a very large rhinoceros are the basis for the description of a new species of Aphelops from Frontier County, Nebraska. The major differences are: the skull is much larger in most dimensions than other Aphelops; it has an extremely elevated occipital region in comparison to Aphelops mutilus; the narial notch is retracted to a point perpendicular to the center of molar one; and the teeth are more hypsodont than any other species of this genus. The sediments which yielded the skull and skeletal parts are considered to be Kimballian in …

The Brule-Gering (Oligocene-Miocene) Contact In The Wildcat Ridge Area Of Western Nebraska, C. Bertrand Schultz, Charles H. Falkenbach, Carl F. Vondra

Bulletin of the University of Nebraska State Museum (1924–2023)

The contact between the Brule Formation (Oligocene) and the Gering Formation (Miocene) can be readily distinguished in the Wildcat Ridge area, as elsewhere in western Nebraska. At the critical fossiliferous exposures at Castle Rock in Scotts Bluff County, the contact on the south face between the two formations is defined as 129 feet above the base of the "Upper Ash" bed, which corresponds to the upper portion of Darton's (1899, PI. C, Fig. D, following p. 754) "sandy phase" in the upper part of the Brule. Certain key beds in the Gering Formation can be traced laterally from a channel …

FOOD is by far the greatest cost in pig production, accounting for between 60 per cent, and 75 per cent, of the total cost, and for this reason it is important that the basic principles of feeding be understood.

Hydatid Disease In Western Australia, K J. Austen

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

BECAUSE hydatid disease is a disease of humans as well as animals every consideration must be given to its control and to the prevention of any possible increase in incidence.

The incidence of hydatids in Western Australia has not, in the past, been very high.

However, the great increase in sheep numbers which has taken place in recent years and which is expected to continue for many years to come, will produce a situation where it could be expected that the incidence of the disease will rise unless stock owners, particularly sheep owners, take appropriate steps to control the tapeworms …

Comparison Of Two Cultures For Use In Preacidified Skimmilk For Cottage Cheese Manufacture, Daryl D. Boddicker

Electronic Theses and Dissertations

Curd formation in a cultured dairy product is brought about by the addition of a bacterial culture capable of producing lactic acid from lactose. The primary function of this culture is to produce sufficient lactic acid to cause coagulation of the caseinate system of skimmilk. A secondary function of the culture is the production of flavor compounds considered to be desirable in these products. The flavor compounds produced by the normal growth of citric acid fermenting organisms are water soluble, and are largely removed during washing of the Cottage cheese curd. Therefore, flavor compounds are normally added to the cheese …

Consumer Evaluation Of A New Low-Fat Spread-Type Dairy Product, Walter W. Wosje

Electronic Theses and Dissertations

For many years the dairy industry has been going through transitional period whereby many marketing and structural changes have resulted. Generally speaking, these changes have been advantageous to the dairy farmer. During the past years there has been a widespread and increasing interest in profitable means of utilization of dairy by-products. Because of their unique and high nutritional value, the most logical method of disposition of these by-products is, from the standpoint of the general welfare, in human food; generally this is also the most gainful method. The high nutritional value of these products also makes them valuable in feeding …

A Study Of The Communities Of Aquatic Macro-Invertebrates Of The Merging Of The Mississippi And Chippewa Rivers, Using A Biplate Substrate Sampler, Robert R. Elbert, Clarence D. Mcnabb

Journal of the Minnesota Academy of Science

Using a biplate substrate sampler, aquatic macro-invertebrates were collected during the fall, winter and spring seasons at the confluence of the Mississippi and Chippewa Rivers along the Minnesota-Wisconsin border. The substrate sampler proved very desirable in pointing out extreme community variations which existed between the two rivers. It was found that the members of a downstream community were a blend of the communities present in upstream tributaries. However, as compared with upstream communities, a shift in dominant organisms occurred. Striking seasonal changes appeared in the invertebrate populations as well as the environment of the rivers. All sampling revealed "clean water" …

A Measure Of Clover Infertility In Ewes, N Davenport

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

SERIOUS impairment of the breeding ability of ewes grazed for prolonged periods on growing pastures containing dominant subterranean clover has been experienced in Western Australia for many years.

The first widespread recognition of the problem coincided with the upsurge of improved pasture establishment based on the Dwalganup variety of subterranean clover in the higher rainfall sections of the wheatbelt and adjacent sheep raising areas to the west and south.

Choking Of Milking Machine Pulsators, G R. Olney

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

THE value of applying the teat cup squeezing action more slowly, by "choking", has been well demonstrated for a number of years.

Leslie and Whittlestone (1938) suggested that brutal teat cups and snappy pulsators could be undesirable because of the trauma caused.

Choking was recommended by them to overcome this.

Worms In Sheep. 3. Control Of Worms By Drenching, R W. Butler

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

DRENCHING for worm control must be carefully timed in relation to the effect of climatic conditions on the development and survival of worm larvae on the pastures, and the seasonal variation in worm burdens carried by sheep.

Phospholipids Of Thiobacillus Thiooxidans, J. M. Shively, A. A. Benson

School of Biological Sciences: Faculty Publications

Cells and spent growth media from sulfur- and thiosulfate-grown cultures of Thiobacillus thiooxidans were analyzed. The phosphatides were examined by thinlayer chromatography, and the products of their hydrolysis by hydrochloric acid and methanolic potassium hydroxide were separated by paper chromatography. The phospholipids in both cells and spent growth media were identified as phosphatidyl ethanolamine, phosphatidyl N-monomethylethanolamine, phosphatidyl glycerol, and diphosphatidyl glycerol. These comprised about 97% of the total lipid phosphorus. Lyso-phosphatidyl-N-monomethylethanolamine and lysophosphatidylglycerol accounted for the remaining 3%. The percentage of the total lipid phosphorus accounted for by each phospholipid depended on the age of the culture.

On The Ecology And Distribution Of Echinococcus Spp. (Cestoda: Taeniidae) And Characteristics Of Their Development In The Intermediate Host, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Echinococcus granulosus (Batsch, 1786) and E. multilocularis Leuckart, 1863 [syn. Alveococcus multilocularis (Leuckart, 1863) Abuladze, 1960] are distinguished by well defined biological and developmental characteristics. Obligatory predator-prey relationships of the hosts segregate the two species ecologically under natural conditions. The larval stage of E. granulosus develops slowly in long-lived ungulates, while that of E. multilocularis becomes infective within a few months in intermediate hosts (rodents) having a life expectancy of less than a year.

Existing parasite-host relationships of these cestodes had become established at least as early as late Pleistocene time, and two biologically distinct forms of E. granulosus can …

New Records Of The Pigmy Shrew Microsorex Hoyi (Baird) In Alaska, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The results of extensive trapping (ca. 7000 small mammals from the Alaskan mainland) indicate that the pigmy shrew, Microsorex hoyi (Baird), is a comparatively rare mammal in Alaska. From January, 1949, to the present, my co-workers and I have collected only seven specimens. These few animals considerably extend the known geographic range of M. hoyi in Alaska.
