We have attempted to discover whether or not certain protein materials, such as albumose, casein, and albumen, when introduced parenterally (peritoneally) into experimental animals, are able to produce organic lesions. These proteins were used alone or in combination with chloroform, which was administered in oil and as an anesthetic. Our results were negative.

Two experiments were conducted to evaluate effects of strain [five in Experiment (Exp.) 1 and six in Exp. 2)] and age (29, 47, and 57 wk in Exp. 1 and 29, 41, and 52 wk in Exp. 2) of commercial broiler breeders on incubation time and chick weight. Highly significant differences in egg weight were found among strains in both Exp. After adjusting for effects of egg weight, significant effects of ...

The present study was conducted to determine the external and internal egg quality of Isa Brown (Gallus gallus domesticus) chicken and Japanese quails (Coturnix coturnix japonica) as affected by storage time under room temperature in the hot weather conditions of Nigeria. Parameters evaluated included egg weight, albumen and yolk indices. For each species, a total number of twenty freshly laid ...

A progressive selection for broiler live and processing performance traits has changed broiler growth patterns during the post hatch period. However, limited information is available to understand whether changes have also occurred during the embryonic stages. This study aims to examine influences of broiler strain on nutrient availability, embryonic development, and nutrient metabolism during ...
