In nature, chicks hatch after 2 to 4 weeks of incubation by the
parents, most often the hen. The hatched chicks provide the
stimulus to the hen to change her work from incubating eggs to
brooding young. This form of brooding chicks is the easiest if
only a few chicks...
An in vitro study was conducted to investigate the metabolism and distribution of Se⁷⁵-selenite and Se⁷⁵-selenomethionine (SEM) in
chick blood. Se⁷⁵-selenite is taken up by RBC (13% within 20
minutes) and expelled into the plasma to become bound to proteins. In
contrast, Se⁷⁵-SEM showed a more gradual and continuous buildup...

During the 21 day incubation period, the fertile egg provides nutrients such as fatty acids for energy and polyunsaturated fatty acids (PUFA) for membrane synthesis to the developing chick. The hypothesis tested in the present study is that the type of PUFA fed to the breeder hen can alter tissue...
Greater sage-grouse (Centrocercus urophasianus) populations declined range wide
during the past 50 years. Grouse populations were 2-3 times larger than the current
population as recently as the early 1970's. In addition to habitat loss and
fragmentation, declines were attributed habitat degradation that caused reduced
productivity. Because chick survival remains the...
