Response from nitrogen and chloride fertilization was measured
in field experiments on winter wheat (Triticum aestivum L. Em.
Thell. var. 'Stephens' and 'Yamhill') grown in western Oregon in an
environment with a range of susceptibility to take-all root rot
(Gaumannomyces graminis var. tritici Walker). Cropping sequences
and expected disease severity...
Agrivoltaic systems promote dual use of land by combining solar energy and agricultural production. Grazing sheep in these systems is popular but research on intentionally designed pastures to increase production is lacking. This study seeks to compare the herbage growth and lamb production in simple, diverse, and legume pasture mixes...
During the peripartum period (3 weeks before through 3 weeks after calving, a.k.a. “transition”), high producing dairy cows experience, among others, , oxidative stress and immune suppression that compromise performance and increased incidence of diseases.Among trace minerals, supplementation of Selenium (Se) can help to improve the transition by enhancing glutathione...
The objectives of this study were to determine the effects of acupuncture in dairy cows on caruncular matrix metalloproteinase type-2 (MMP2) tissue concentration and enzyme activity at 0, 2, and 4 hours after calving. Immediately after natural calving, a caruncle was obtained from the body of the uterus and flash...
Our objective was to identify the biological response and the cross-talk between liver and mammary tissue after intramammary infection (IMI) with Escherichia coli (E. coli) using RNAseq technology. Sixteen cows were inoculated with live E. coli into one mammary quarter at ~4–6 weeks in lactation. For all cows, biopsies were...
Among early adolescents (10-14 years), poor diet quality along with physical inactivity can contribute to an increased risk of obesity and associated biomarkers for chronic disease. Approximately one-third of United States (USA) children in this age group are overweight or obese. Therefore, attention to factors affecting dietary intake as one...
The utilization of ⁷⁷ [superscript m] Se, half life 17.5 s, and ⁷⁵ Se, half life 119.8 d, for quantification of trace amounts of Se in well water and biological materials by means of instrumental neutron activation analysis (INAA) is described. A Se detection limit of 0.03 ppm was achieved...
The effect of increasing numbers of non-commercial
farms, or hobby farms, on commercial agriculture is examined
through a comparison of Census of Agriculture data for the years
1978 and 1982. During this time, State Land Use Goal #3,
mandating the protection of farmland, was firmly in place and
exclusive farm...
