Two experiments were conducted using coturnix quail to determine
the effects of dieldrin and calcium on the reproductive performance
of this species. In both experiments quail were raised on a
soybean-meal glucose-monohydrate ration. At 25% egg production
the quail received diets containing 0, 10 or 25 ppm of dieldrin in...
RNA tumor viruses, such as avian myeloblastosis virus (AMV)
and MC29 virus, cause malignant transformation of the cells they infect.
Transformed cells are able to continually produce progeny virus
particles.
Evidence is given that RNA-dependent RNA polymerase is present
in virus infected cells. RNA-dependent RNA polymerase isolated
from AMV-infected myeloblasts...
The research presented in this thesis was designed to evaluate
the effects of feeding alfalfa hays from the Klamath Basin of Oregon
in practical dairy rations on milk fat production in high-producing
Holstein cows. Thirty-two second lactation or older animals estimated
to be capable of producing at least 70 lbs...
The adaptiveness of polygyny in passerines poses a particularly
intriguing problem. The altricial young of this group require extended
parental care, but young of polygynous pairings generally lack the undivided
attention of the male which young of monogamous pairings receive.
Polygynous offspring may thus be undernourished and experience
greater mortality....
