Some commercial broiler hatcheries in India do not have cool room egg holding facilities and pre warming facilities.They order and receive hatching eggs from remote areas involving long travel hours in trains and road transport. These are multi stage incubation practices. They receive the eggs, unpack them from the boxes, keep them in trays in a room adjacent to setter room where they transfer the eggs on setter trays and set the eggs on the same or next day.
These hatcheries often experience low overall hatch with many eggs removed as infertie at candling done on day 18 prior to transfer to hatchers, particularly in summer. In fact these are early or very early embryonic mortality due to transit stress but are broadly termed as infertiles blaming the breeder farm for the same.
Are there any suggestions for improving hatch performance under such field conditions?
