Literature-based review on designing an experimental project regarding placement and orientation of artificial nest boxes related to successful nest box adoption and chick survival in Barn owls within the Willamette Valley.
Data from the southern Cascade Mountains of
Oregon has been collected for application in computer
analysis of snowfields. Vegetation type, canopy
cover, slope, aspect, insolation, and snowfield
ground truth delineation are given consideration.
In addition, a procedure for transferral of data
onto Landsat imagery was derived.

Hens were artificially inseminated at 8:00 a.m., 4:00 p.m.
and 11:50 p.m. Fertility was found to be significantly lower after
8:00 a.m. inseminations than after 4:00 p.m. or 11:50 p.m. inseminations
for 2 to 6 days, 2 to 9 days and 10 to 17 days following inseminations.
Slightly higher fertility...
An attempt was made to create a hormonal environment of the
uterus comparable to that near the time of natural laying and to
eliminate the effect of a hard-shelled egg on fertilization. Hens without
hard-shelled eggs in their uteri were injected with the posterior
pituitary hormones, oxytocin and arginine vasopressin,...
To observe the effects of oviposition as related to time of insemination
on fertility, four trials were conducted in which individually
caged White Leghorn hens were artificially inseminated with 0.05 cc
of undiluted mixed semen obtained from 4 to 5 cockerels. These inseminations
were made at 9:45 a.m. , 10:00...
A trial was conducted to determine the effects of increasing
levels of water restriction on body weight, feed consumption, feed
conversion and mortality of broiler chicks to eight weeks of age.
In addition, the effects of water restriction on water:feed ratios,
water consumption per pound of body weight and on...
In this study, pheromone and skin lipid samples collected from red-sided garter snakes (Thamnophis sirtalis parietalis) were exposed directly to either full-spectrum light or full-spectrum plus UVB light. In addition, female and male snakes were exposed to daily doses of either full-spectrum or full-spectrum and UVB light, after which the...
One group of four adult White Leghorn male chickens was fed a
diet containing 7.3% linoleic acid and 32.4 mg/ kg of added vitamin E
(group IV) for 50 weeks which was designated as the positive control.
A second lot (group I) containing 14 males received the same level of...
