Digestibility Studies With Western Wheat Grass, Marvin John Wurster

Electronic Theses and Dissertations

In order to make the most economical usage of our range forages it is essential that we know when the forage is most digestible in order for livestock to obtain maximum benefit from it. For many years cutting date has been the most common measure used to determine when a forage contains the most nutritive value. In many grasses emergence of the seed head or seed maturity has been used to determine when a particular forage should be harvested, However, western wheatgrass (Agropyron mithill) is not dependent on seed for reproduction and under range conditions often does not produce a …

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.

Consumption And Digestion Of Dry Cupped Clover, E T. Bailey

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

FARMERS often ask if sheep eat the dry seed heads of cupped clover (Trifolium cherleri) and, if so, how much of the seed is digested.

Agriculture In Western Australia : Past, Present And Future, A W. Hogstrom

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

THE post war period has seen very rapid growth and changes in the agriculture of Western Australia.

Almost every industry and region of the State has contributed to the growth of rural production which in turn has been responsible for much of the development in other sectors of the economy.

Cattle Stocking Rates In A Higher Rainfall Area, R Sprivulis

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

THE 1965 Pardelup cattle stocking rate trial was conducted with Hereford cross yearling steers on annual pasture of Mt. Barker sub. clover, Wirnmera ryegrass and various volunteer annual species.

This was topdressed with 186 lb. of superphosphate per acre in mid March.

Trans-O-Hydroxycinnamic Acid Glucosylation In Cell-Free Extracts Of Melilotus Alba, A. Kleinhofs, Francis A. Haskins, Herman J. Gorz

Department of Agronomy and Horticulture: Faculty Publications

The glucosylation of trans-o-hydroxycinnamic acid has been demonstrated in cell-free extracts of MeliIotus alba. The reaction requires UDPG, a sulfhydryl compound, and an active extract from sweet clover leaves. The product of the reaction has been tentatively identified as trans-β-D-glucosyl-o-hydroxycinnamic acid.

Ontogeny And Anatomy Of The Flower Of Limnocharis Flava (Butomaceae), Robert B. Kaul

School of Biological Sciences: Faculty Publications

The flowers of Limnocharis flava (L.) Buch. are borne in an indeterminate umbel and each consists of three sepals, three yellow petals, and about 18 carpels surrounded by numerous stamens and staminodia. The androecium is centrifugally developed, and the last-formed members are staminodial; it is supplied by branching vascular systems. Carpels arise almost simultaneously, and a prominent residual floral apex remains. The carpels are partially conduplicately closed and are also primitive in possessing laminar placentation and in lacking differentiation of a style. The gynoecium is essentially apocarpous, but there are slight fusions of adjacent carpels near their ventral margins where …

A Comparative Osteological Study Of Two Species Of Colubridae: (Pituophis And Thamnophis), Robert E. Bullock, Wilmer W. Tanner

Brigham Young University Science Bulletin, Biological Series

The complete skeletal anatomy of Pituophis catenifer deserticola Stejneger is described in detail. The osteology of this species is compared with that of Thamnophis radix haydeni Kennicott in the following areas: atlas, axis, first thoracic, other thoracic lumbar, anterior caudal, middle caudal, and posterior caudal vertebrae, as well as the skull and hyoid apparatus.

Many structural similarities exist in these two species of colubrids. The more important structures or aspects in which similarities were observed are: (1) the natural division of the vertebral column into regions and subregions, (2) the gross morphology of the various types of vertebrae, (3) the …

Isolation Of A Toxic Substance From Centaurea Repens, Merton E. Sprengel

Loma Linda University Electronic Theses, Dissertations & Projects

A poisonous steroid-type compound was isolated from Centaurea repens. After extraction with absolute ethanol, removal of the solvent, addition of 2% HCl to precipitate the pigments, and filtering, the pH was adjusted to 9 with aqueous anunonia. This solution was exhaustively extracted with chloroform, evaporated to dryness, and extracted with ethyl ether.

This fraction was chromatographed on silica-gel plates, using 10:1 1,2-dichloroethane-methanol as the developer. The band at Rf 4.2 was removed and found toxic to mice. Labored, slow, gasping respiration and frequent involuntary muscular contractions became apparent within a few minutes following the intraperitoneal injection into each animal. Death …

An Ecological Life History Of Budsage In Western Utah, Benjamin W. Wood

Theses and Dissertations

The ecological life history of budsage (Artemisia spinescens D.C. Eaton) was investigated during 1963 and 1964. The field studies were conducted at the Desert Experimental Range in Millard County, Utah. Laboratory studies were done at Brigham Young University. The different community types in which budsage grows were described and the physical site factors, viz. climate, soil texture, total soluble salts, hydrogen ion concentration of the soil, carbonate content and soil moisture were investigated. Phenology of seedlings, root systems, shoot and flower development, and plant longevity were investigated. Studies were also made on the effects of different seasons and intensities of …

Saponin Content And Some Pod And Blossom Characteristics Of Alfalfa As Related To Seed Infestation By The Alfalfa Seed Chalcid, Ronald D. Morse

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The alfalfa seed chalcid, Bruchophagus ruddi Guss., is a jet-black hymenopteran wasp. The destructive nature of this pest has been recognized since the latter part of the nineteenth century. Every year thousands of acres of alfalfa seed are destroyed, with infestation reaching as high as 8 5 percent in some areas. In Utah the chalcid annually ruins from 5 to 25 percent of the alfalfa seed. Much of this damage goes unnoticed, as infested seed is commonly blown out in the trash during harvesting and cleaning operations . The extent of damage is not restricted to the United States. Wherever …
