  • The use of 2, 4-d, paraquat and dinoseb for control of filbert (Corylus Avellana L.) suckers

    Creator:
    Reich, Jack Ernest
    Abstract:
    The control of filbert (Corylus Avellana L.) suckers by means of herbicides was investigated in three phases during 1968 and 1969. (1) Screening trials, on canned filbert trees in the greenhouse, to determine the effectiveness of various herbicides and concentrations in controlling vegetative growth. (2) A summary experiment in the...

  • Relationships between hemoglobin genotype and production in cross-bred ewes. I. Reproduction and lamb production : II. Wool and milk production and health related traits

    Creator:
    Dally, Martin R.
    Abstract:
    I. REPRODUCTION AND LAMB PRODUCTION Relationships among hemoglobin (Hb) genotypes and reproduction and production traits were examined in 294 four- and five-year-old North Country Cheviot, Dorset, Finnsheep or Romney x Suffolk or Columbia-type crossbred ewes. Hb BB ewe lambs were youngest at first estrus and Hb AA ewe lambs were...

  • Effect of feeding concentrates of Lactobacillus lactis on fecal bacterial flora, scouring, and weight gain in swine

    Creator:
    Sheggeby, Gene G.
    Abstract:
    A frozen concentrate (>10⁹ cfu/ml) of a human strain of Lactobacillus lactis (strain MLC) was fed to swine. Bottle feeding resulted in reduced fecal coliform counts and incidence of scouring in nursing pigs. In one group of pigs treated 54 days, the Lactobacillus to coliform ratio was 1280:1; in the...

  • Mercury and cadmium binding proteins in marine mammal tissues

    Creator:
    von der Trenck, Karl Theodor
    Abstract:
    The subcellular fractions of liver and kidney from three bearded seals (Erignathus barbatus nauticus) and three walrus (Odobenus rosmarus divergens) were analyzed for cadmium and mercury content, and the results were compared with the results of subcellular fractionation of the same organs from two sea lions (Zalophus callfornianus californianus) obtained...

  • A sampling procedure to detect alternative actions in a decision model for choosing among apple harvesting systems

    Creator:
    Rudkin, Terry Harrold
    Abstract:
    Numerous analytical aids are available to apple producers to assist them in the decision problem of choosing among alternative apple harvesting systems. However, a majority of these techniques fail to recognize the effect of apple orchard yield variability on system performance and economic efficiency. Furthermore, many of the suggested procedures...

  • Measurement and scrubbing of SO₂ and NOx from boiler flue gases

    Creator:
    Reichel, Rolf Hubertus
    Abstract:
    At the Oregon State University heating plant the primary source of heat energy is natural gas with crude oil as the standby supply of fuel. In the future, as natural gas becomes a rarer commodity, more reliance will be placed on the use of the more expensive, more polluting, but...

  • Biological and economic effects of flushing and creep feeding in sheep

    Creator:
    Taiwo, Bolaji
    Abstract:
    One hundred two mature blackface crossbred ewes were randomly divided into three equal groups to examine the effects of feeding management during mating on blood chemistry, weight change and subsequent reproductive performance. Group I was kept in drylot from 17 days before through 17 days after the start of mating....

    Creator:
    Rea, Campbell Cary
    Abstract:
    Siletz Bay is a drowned river valley filled with Holocene alluvial and estuarine sediments and is separated from the ocean by a sand spit 3.8 km in length. Since the area was settled by white man in the 1890's, the bay has apparently experienced rapid siltation, due to increased farming...
