The genetic control of changes in unselected traits of
Wrolstad Medium White turkeys divergently selected for
semen ejaculate volumes (SEV) for 16 generations (G) was
studied. Genetic parameters were estimated in G 10 to 14
for embryonic mortality (EM), the incidence of pipped eggs,
and for total plasma cholesterol (PC)...
Three experiments were conducted to determine if a new variety of
triticale (Flora) would maintain seminal production of Medium White (MW)
breeder toms and to ascertain the minimal dietary crude protein (CP)
required by breeder toms. In Experiment 1, 4 dietary treatments with 10
males each, were fed ad libitum...
Habitat use and reproductive success by Merriam's wild turkey
(Meleagris gallopavo merriami) were studied in Wasco County, Oregon,
during 1981-82. This low density turkey population selectively used
forested cover types characterized by a variety of structural
features, species, and age classes. They avoided monotypic forested
cover types, used non-forested cover...
An experiment was conducted to evaluate a breeder diet
containing a yeast culture as a means of improving the
reproductive performance of two genetically dissimilar lines
of turkey hens (designated as L and H). Two hundred hens of
lines L and H, 100 hens per line, were housed in a...
