Livestock grazing has been indirectly related to sage-grouse (centrocercus
urophasianus) declines in the western United States and southern Canada; however,
there is a lack of scientific research that directly relates the two. Our objective was
to investigate the influence of livestock herbivory on sage-grouse nesting habitat by
determining the spatial...
The objectives of the experiment were to: 1) determine the relationship
between overstory canopy cover and ungulate herbivory on understory production
composition and diversity and 2) determine the effects of timber harvest, ungulate
herbivory and season of use on botanical composition and nutritional quality of
beef cattle diets. Three randomly...
Testes size as an indicator of future growth was examined
in a total of 45 bull calves from spring calves born in 1978
and 1979. Scrotal circumference measurements were used as the
physical indicator of testicle size in the live animal.
Growth traits studied were preweaning average daily gain,
weaning...
