The influence of calcium source (limestone and oyster shell) and particle size (<0.1 mm; 0.85 to 2 mm) on laying performance, egg quality, and bone properties were examined in laying ducks by a 2 × 2 factorial arrangement of treatments. Longyan females (288) with similar BW at 24 wk of age were randomly allotted into 4 treatments, each with 6 replicates of 12 individually caged birds and studied...

Two experiments were carried out to determine the potential of oral yolk derived specific antibody against aflatoxin B1 in Japanese quails. In the first experiment egg yolk derived antibody against aflatoxin B1 was produced in layer quails. The potential of aflatoxin absorbent of the eggs from immunized and non-immunized layers was assayed in vitro. Egg yolk extracts derived from aflatoxin-BSA ...
in the first part of this thesis we explored wetting and its dynamics for small droplets. first, we showed how a simple feature of water droplets on a surface, i.e. laplace pressure, can be exploited to build a micropump. we investigated capillary pumping in microchannels both experimentally and numerically. putting two droplets of different sizes at the in/outlet of a microchannel, will ge...
Chicken eggs represent an important source of protein to the growing human population and also supply repositories of unique genes that could be used worldwide.
