Prostaglandin F (PGF) concentrations in the serum of laying and nonlaying hens and of cocks at various times during a day were measured by radioimmunoassay. The serum concentration of PGF was higher in laying hens than in nonlaying hens or cocks without regard to time of day. In all birds, the concentration showed a peak at 2 h after onset of light (0700 h). In laying hens on the day of laying ...

The form of apparatus 1 shown in Fig. 1 has been found very convenient for the determination of the migration of fine suspensions in the electric field. Its essential difference from the usual cataphoresis apparatus is that the whole is inverted so that the central portion, which contains the suspension which is to be studied, is above the heavier electrode solutions and may be left open. This ...

This study was to assess the effects of organic chromium supplementation on productive traits, some serum constituents and immune status of Bandarah laying hens and semen physical properties for cocks in winter season. The mean value of temperature and relative humidity during that period in the house was 12.3± 2.2°C and 67.4 ± 6.5%, respectively. One hundred and fifty laying hens and forty coc...

banned psychoanalysis as a Jewish science and there was no organized psychotherapy in a situation dominated by racial biology. In Psychotherapy in the Third Reich, Cocks recovered the history of the German institute for psychological research and psychotherapy, generally known as the Goering Institute after its chief, the psychotherapist Mathias Goering, a cousin of the infamous Hermann Goering...

BACKGROUND In previous studies, the Mx Gene has been demonstrated to confer positive anti viral responses in chicken. The amino acid variation of Asn (allele A) at position 631 was specific to positive antiviral Mx/resistant, while, that of Ser (allele G) was specific to negative Mx/susceptible. This research was aimed at selecting one of the native chicken breeds which was found out to be resi...

The aim of the present study was to investigate how a higher temperature at a comparable period during chicken incubation influences the muscle development and the meat quality in the animals post hatch. Therefore half of fertilized eggs of the broiler genetic Cobb were incubated between ED 7 to 10 at 38.5 °C instead of 37.5 °C (control group). At the day of hatch (Day 21) the hatch rate was 86...
