Some of the important factors are the gas concentration, at 36 g potassium permanganate and 54 mL formaldehyde per cubic metre; the duration of fumigation, 20 minutes; the relative humidity, high; and subsequent ventilation for 24-72 hours before packaging, because otherwise adverse effects on hatchability can be expected. A respirator or gas mask should be used during fumigation, as shown in Fig 8. This procedure does not appear to affect hatchability, even with a rising or falling temperature during fumigation. Although fumigation would usually be conducted within a few hours after lay, hatchability was not affected when eggs were fumigated after storage for as long as 3 Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Proudfoot, F.
