The objective of this research was to clarify the basis
of subfertility in Delaware roosters. It was anticipated
that a sensitive method would be needed to compare seminal
plasma protein composition between subfertile and fertile
roosters. Consequently, the applicability of two-dimensional
electrophoresis was tested as a tool for the
analysis...
Dekalb XL Single Comb White Leghorn pullets were
immunized against poly-L-glutamic acid (PGA) complexed with
methylated bovine serum albumin (MBSA) at 9 weeks of age.
Pullets immunized against MBSA as well as non-immunized
pullets served as controls. At 18 weeks of age, pullets
were moved from a floor pen into...
Agonistic behavior among three species of Microtus live-trapped
near Corvallis, Oregon was recorded in order to interpret habitat
segregation by the species in areas of syrnpatry. The method used to
measure agonistic interaction was similar to that of Colvin (1970).
Agonistic behavior was recorded under red light in a neutral...
