Taxonomic Review : Miridae Of The Nevada Test Site And The Western United States, Harry H. Knight

Brigham Young University Science Bulletin, Biological Series

Approximately 5,000 specimens of plant bugs were collected at the Nevada Test Site between 1959 and 1965. Greatest emphasis was given to collecting from June 10–24, 1965, when the desert areas at the test site were unusually profuse with blooming vegetation. A total of 160 species representing 50 genera was taken at the test site. Of these, 7 genera and 96 species are new to science.

Comparative data for these and additional species from other parts of western North America are also included. These represent an additional 449 species, of which 5 genera and 148 species are new to science. …

Bluetongue Of Sheep, M R. Gardiner

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

BLUETONGUE is a serious disease of sheep, mainly of introduced European breeds, throughout the African continent.

It is maintained there by wild and domestic ruminants in the presence of certain insect vectors (carriers).

The disease has probably existed there from immemorial times among the indigenous ruminants, emerging as a recognised disease only when the much more susceptible European breeds were brought into the continent.

Wheat In Development Programmes For New Esperance Farmers, R J. Doyle, G. D. Oliver

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

The aim of the exercise was to find out if a new settler concentrating on sheep, with $20,000 available for development after acquisition of land, could make a reasonable living for himself and his family while developing his farm.

Renin Granularity In The Mouse Kidney, R. Williams Soller

Senior Scholar Papers

Briefly. the rennin-angiotensin-aldosterone triangle can be thou ht of as a regulator of renal perfusion. Renin, released by the kidney in response to any threat in its perfusion n, acts on its substrate to produce angiotensin I, a mild vasoconstrictor which by means of plasma converting enzymes secretes angiotensint II. This latter product not only stimulates aldosterone output by the adrenals, but also supports the animals’ blood pressure. With aldosterone binding at the distal tubules in the kidney and this causing increased sodium retention, restoration of renal perfusion occurs – a phenomenon which shuts off the original signal for rennin …

Land Resource Evaluation - Ninety Mile Tank Report On Trials Conducted 1968, 1969 And 1970 By Plant Research Division And Wheat And Sheep Division, J W. Gartrell

Experimental Summaries - Plant Research

In the late 1920's the seven million acres of virgin land between Hyden and Salmon Gums were considered for settlement under the "3,500 farms scheme" because it constituted "practically the only large area of wheat lands in a suitable climatic zone not then settled in Australia" (Teakle 1939). At that time the sandy scrubplain soils were more a liability than an asset because methods of profitably farming the light soils had not then been evolved. These useless scrubplains merely increased the distances between patches of' more f'ertile soils. The scheme for settlement was based mainly on the potential of' the …

A Brief History Of The Namru-3 Medical Zoology Program, Harry Hoogstraal

United States Naval Medical Research Unit 3: Publications

The NAMRU-3 Medical Zoology program began during Easter week of 1950. We had just closed the NAMRU-3 field station at Torit, in Equatoria Province of soulheastern Sudan, and were heading homeward to the United States. However, the offer to remain in Egypt for a year or two to develop a Medical Zoology department at NAMRU-3 provided an interesting challenge after working for several years in tropical forests and grasslands of Africa and other continents. We shall briefly describe subsequent events under four headings: (1) Medical Zoology in Egypt, (2) Ticks and Tickborne Diseases of the World, (3) Kala Azar in …

Amsinckia Or Yellow Burr-Weed (Amsinckia Spp.), G R W Meadly

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

YELLOW BURR-WEED is widely established in the Wimmera and Mallee districts in Victoria, presumably introduced with fodder brought to this country from the United States about 1914.

It is a problem in Oregon and other north west wheat areas of America.

The weed is also widespread in New South Wales, being most troublesome in the wheat-growing sections of the Riverina. It is not established to the same extent in South Australia and Queensland.

The recent discovery of areas infested with yellow burr-weed at Merredin prompted the Agriculture Protection Board to declare it a primary noxious weed for Western Australia.

Weight Gain And Carcass Measurements Of Pigs From Gilts Fed Adequate Vs. Protein-Free Diets During Gestation, W. G. Pond, J. A. Dunn, G. H. Wellington, J. R. Stouffer, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

Fifty-two weanling pigs from six litters(Pond et al., 1968) were fed a standard 18% protein corn-soybean meal diet from weaning to slaughter. The six litters were from gilts paired on the basis of parturition date so that one gilt fed the control diet and one fed the “protein-free” diet (0.5% protein) from week 4 of pregnancy to parturition made tip each pair. Each dam was fed the control diet throughout lactation and nursed one-half of her own litter and one-half of a pairmate’s litter resulting from reciprocal transfer of one-half of each litter at birth. Individual bodyweight gains and feed …

A Study Of Some Physico-Chemical Changes In A Spread-Type Dairy Product During Storage, Alfredo E. Gudeikis

Electronic Theses and Dissertations

In the Dairy Science Department at South Dakota State University a new dairy spread product has been developed which has only 50% of the fat content of butter or margarine and 60% of the calorie value of the higher fat products. It is increased in solids content with nonfat milk solids. The purpose· of developing this product was to obtain a new outlet for milk constituents; desirably it was to be one that could regain the market sales which were lost by butter and are now enjoyed by the margarines. The high price of butter compared with the substitute product …

The Feeding Value Of High Dry Matter Corn Silage, Myers J. Owens

Electronic Theses and Dissertations

The important of corn in dairy cattle feeding is generally acknowledged. A popular way of preserving the crop is to make corn silage, thus using the whole plant for feed and preserving maximum feed per acre. The increased utilization of corn silage by dairymen may be due to its high energy yields per acre, high acceptability by cattle, and ease with it is incorporated into automated systems of harvesting and feeding. The increasing importance of corn silage in the United State is evidenced by the increasing acreages harvested as corn silage. In 1950 there were 4,937,000 acres planted with a …

Schistosome Dermatitis At Basswood Lake, Minnesota, James A. Zischke, Deloris Palmquist Zischke

Journal of the Minnesota Academy of Science

During the summer of 1965 cases of schistosome dermatitis were reported at the Associated Colleges of the Midwest Wilderness Field, Station on Basswood Lake, Minnesota. Collection and isolation of gastropods from the lake revealed an extremely high incidence of Trichobilharzia ocellata infections in Lymnaea stagnalis. A flock of semi-domestic mallard ducks first introduced al the lake in 1963 are believed to be the principal definitive hosts contributing to the epidemiology of the parasite in the area.
