,Boron–Nitrogen Dehydrocoupling,abolism has been gathered. Use of newly designed methodology, of more sensitive techniques, and of the “molecular approach” allow for reevaluation of the results of older experiments as well as for progress in understanding avian carbohydrate phenomena at a lower level of (organismic) organization.

Group Actions and Vector Fieldsstages, they usually do not persist in adult life. A persistent right ovary and oviduct have been reported in some avian species (raptors) and in rare instances in ducks and chickens where both ovaries and oviducts were functional (see Sturkie, 1965; Lofts and Murton, 1973).

The weight of the testes in chickens comprises about 1% of the total body weight (Parker, 1949), or about 9–30 g per single testis at sexual maturity, depending on breed, state of nutrition, and other f
