The detection in his testis of lutear cells like those in hens makes the conclusion highly probable that it is these cells that cause the suppression of cock-feathering in both the Sebright ...

in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
Biochemical and Physicochemical Changes in Spent Hen Breast Meat Biochemical and Physicochemical Changes in Spent Hen Breast Meat
An experiment was conducted to study the biochemical and physicochemical changes with respect to improvement in tenderness of spent hen breast meat. Breast muscle obtained from freshly slaughtered spent hens (72 wk old) was divided into 5 equal lots and dipped in 1 mM NaN3 before being packed in low-density polyethylene pouches under aerobic conditions and stored at refrigeration temperature (4...
