Evaluation of low quality roughages and agricultural by-products as livestock feed

Creator:: Hussain, Imdad
Abstract:: Nine feeding trials and four laboratory scale experiments were conducted in this study. The study consisted of: (1) use of grass straw:corn juice (CJ) silages with fishmeal and/or alfalfa hay supplementation in beef heifers, sheep, pregnant dairy heifers, water buffaloes and Hereford cows; (2) use of cull onions:grass straw silages...

Relationships of clay mineralogy to landscape stability in Western Oregon

Creator:: Taskey, Ronald D. (Ronald David), 1944-
Abstract:: Soil erosion by mass wasting is the major problem on forest lands of the Pacific Northwest, The clay fractions of soils from a large number of sites in Oregon's Western Cascades were characterized in order to determine the relationships of various clay materials to mass movements. Each site was either...

Evaluation of three methods of selection in relation to yield and yield stability in winter wheat (Triticum aestivum Vill., Host)

Creator:: Charoenwatana, Terd, 1937-
Abstract:: The effectiveness of early generation selection for yield and yield stability and the possible identification of superior parental combinations were studied in winter wheat populations representing different levels of genetic diversity. Experimental material for evaluating yield stability consisted of nine bulk and seven modified bulk populations derived from nine parental...

Thermo-hygro rheological behavior of materials used in the manufacture of wood-based composites

Creator:: Ren, Shan
Abstract:: Thermo-hygro-rheology of wood-adhesive systems plays an important role during the hot pressing process of wood based composites. The principal objective of this research is to quantitatively study the thermo-hygro rheological characteristics of wood-adhesive systems used in such composites. This is with a view to providing material characteristics which may be...

Effect of moisture stress on yield and quality of winter wheat seed

Creator:: Assuncao, Marcos Vinicius
Abstract:: Two experiments were conducted to determine the effects of moisture stress on physiological changes that occur during the vegetative and reproductive stages of the wheat (Triticum aestivum L.) plant, and to relate these effects to seed yield, quality and performance. In a field experiment, different levels of moisture stress were...

Unoccupied aircraft systems in forest monitoring applications

Creator:: Barker, Matthew I.
Abstract:: In recent years, unoccupied aircraft systems (UAS) have become increasingly affordable and straightforward to incorporate in monitoring applications of forested ecosystems. This shift has facilitated interest in using these tools to monitor aspects of forest ecosystems including vegetation health, forest structure and composition, and potential habitat provided by these systems....

Genetic polymorphism of sheep hemoglobin

Creator:: Templeton, Joe Wayne, 1941-
Abstract:: Five breeds of sheep (Columbia, Targhee, Rambouillet, Lincoln, and Suffolk) were found to possess two hemoglobin types (Hb. A and Hb. B) when their hemoglobins were examined by disc gel electrophoresis. The hemoglobin alleles proved to be co-dominant. Three of the breeds (Columbia, Targhee, and Rambouillet) were maintained at altitudes...

Chemical control of Elodea densa Planch. and other submersed aquatic plants as influenced by several environmental factors

Creator:: Mackenzie, John William, 1939-
Abstract:: Elodea densa Planch. was exposed to diquat (6, 7 dihydrodipyrido [1,2-a: 2', 1'-c] pyrazinediium dibromide), alone and in combination with disodium endothall (disodium salt of 7-oxabicyclo [2.2.1] heptane-2, 3-dicarboxyclic acid), and copper sulfate pentahydrate. Studies were conducted in coastal lakes of Oregon infested with E. densa. Dichlobenil (2, 6 dichlorobenzonitrile)...
