This research was conducted in the Mamora National Forest of
Morocco to: (1) Evaluate the effect of cork oak (Quercus suber L.)
crown cover on seasonal herbage production, nutritive quality, and
foliar cover on two distinctive sites in each of two years (1982,
1983) and to (2) assess the effects...
This study was undertaken to evaluate the dry-weight-rank and
microscopic point methods for determining botanical composition on
perennial ryegrass (Lolium perenne L.) - subclover (Trifolium
subterraneum L.) and tall fescue (Festuca arundinacea Schreb.) -
subclover pasture mixtures throughout a grazing season.
Botanical composition was determined on a monthly basis from...
This research was conducted in the Mamora cork oak
forest of Morocco to: (1) Describe the impacts of sheep
grazing (none, 35% use, 70% use) in March, April, May and
June of 1987 and 1988 on seasonal forage production; (2)
evaluate the effects of these factors on annual changes
in...
This research was designed to evaluate the effect of
sheep grazing on Douglas-fir water potential, growth, and
understory forage production in a small-scale silvopastoral
agroforestry system, at Peavy arboretum approximately
13 km North of Corvallis, Oregon. Treatments
examined included all possible combinations of two sheep
grazing management treatments (grazed vs....
T cells are one of the key cells in the immune system. Although they are not the first line of defense against a pathogen, their functions can greatly enhance the phagocytosis and destruction of pathogens as well as the development of antibody responses. Furthermore, even when responding T cells have...
Sheep and cattle dietary preferences were determined on tall fescue-subclover ( Festuca arundinacea-Trifolium subterraneum) and
perennial ryegrass-subclover (Lolium perenne-Trifoliuni subterraneum)
pastures in western Oregon during the spring and summer periods
of 1964 and 1965. Esophageal-fistulated Willamette ewes and
Hereford and Hereford-Angus yearling cattle were grazed separately
on each pasture mixture...

Seed yield in ryegrass (Lolium spp.) is the
product of the number of fertile tillers per unit area
and seed weight per spike at maturity. These
components of yield develop through a series of growth
stages beginning with tiller bud initiation and
finishing with seed filling. Environmental conditions
during plant...
