Civil Defense Leader - University of Idaho, AglJcultural Extension Service Black, Extzion Poultry Specialist - University of Idaho, Agrioultural Extension Service In t'sa event of nucl( disaster or overt attack on the United States, the poultry industry:would be a number one source of food for human consumption. This would be especially- ,during recovery phase of the disaster. The food production capacity of the natin wollid be sesly affected and the time to recover production capacity for mav types. of Too sn. as food crops, would necessarily be as much as two or more growing seasons. The livestock and poultry industries will have heavy demands made on them to feed our nation during•the interim. There ,are a -nuaber,of reasons why the poultry industry will be a major source of food. , • , 10 Both meat and eggs are produced simultaneously. 2. The period of time, from birth to production for poultry is much shorter ,ithan for -livestock. Increases in poultry numbers and production would , require much shorter time to accomplish than increased production in other livestock or agronomic operations. 3 Poultry is the m.Ft resistant of domestic livestock to radiation. They have more chance to st27rive and continue production. ** 4. 'Very little of ay radioactive isotope would be deposited in the eggs or meat. Strontium c,4:) in laying hens is primarily deposited in the shells of theeggs. 5v Poultry is the mott easily handled of domestic livestock. 6. Poultry is generally raised in buildings which can be tightly closed to •afford good. prptetion from fallout. 7;: iou1tr7 t5 generally fed from covered, and therefore uncontaminated, feed supplies. 8. It is generally much easier to supply adequate water to keep poultry in production for the duration of the emergency than for other types of live- stock, 9. It is relatively easy to maintain production during a period of emergency, in terms of time and labor requirements. ** HOW DOES RADIATION AFFECT POULTRY? According to such research as is available, poultry can take more radiation without damage or fatality than any other of our domestic livestock. The lethal dose for 100% fatality of all birds exposed is 1200 roentgens as compared to about 600 roentgens for cows. We must recognize, however, that some birds will die with less exposure than this. Up to 500 to 600 roentgens exposure is required to affect egg production. At these exposure levels egg production drops. The minimal levels are reached during the second and third weeks following exposure. Near normal production returns by about the ninth week in those that survive. The rate of recovery is apparently directly related to the level of exposure. Exposure levels below 500 roentgens apparently have some affect on egg production but not enough to be significant in the research studies conducted. At exposures up to 200 roentgens there is no drop in egg production. In flocks of birds exposed to fatal levels of radiation, over a short period of time (a few hours) deaths begin to occur about the eighth day and continue for about 27 dam. The higher the dose, the sooner symptoms of radiation sickness appear. Initially there is a shaking of the head. Depression develops within a few days and the birds crouch in a sleeping position for hours at a time. At this time they extend their necks forward and downward over the feed and water troughs, rarely moving for long periods of time. Combs and wattles develop a pendulous edema. Diff- iculty in breathing and a serious discharge are prominent. Droppings become green -2- at this time and death follows shortly. 7r birds that survive for longer than 35 days after exposure there is often a loss of feathers. It is the belief of the Subcommittee on Livestock Damage of the Advisory Committee on Civil Defense, National Academy of Sciences - National Research Council, that those birds survivieg 30 days or longer will be the ones to survive six months or longer. This information taken from Publication No, 1078, National Academy of Sciences, National Research Council, "Damage to Livestock From Radioactive Fallout in Event of Nuclear War". A Report of the Sub emir t.t s on Livestock Damage of the Advisory Committee on Civil Defense. PLAN TO PROTECT YOUR POULTRY Poultry is unique in the livestock industry in that laying hens either produce or they dongt. There is no stopping prech otion temporarily and then starting again. Therefore pit is most important that poultrymen plan to provide protection from fall- out and feed and water for their birds during the period of an emergency. Inventory Inventory your farm to determine what buildings offer the best protection. This will probably be the building which can. be shut up tightest and has water supplies in it. It should also be close to the source of feed for your birds. In most in- stances it will probably be the poultry house. Determine how many days feed you have under cover. Determine how much water storage you have in the buildings which will house your poultry in event of s disaster. Plan.for Shelter After inventorying your facilities, feed and water supplies, plan for protect- ing your birds. Plan which building or buildings you are going to keep them in and be certain that you figure adequate space requirements per bird. These build- ings will be shut up as tightly as possible during a nuclear emergency. Con- sequently the space requirement per bird will be higher than for housing under -3- normal conditions. You must figure on providing at least three sq. ft, per bird for hens in production and 2 sgofto for broilers. If you find that you do not have enough space for all of your birds, plan which you intend to protect first and where you will put them, which you intend to protect second and where they will be put, and so ono You will want to protect the most valuable first." It is- better to be certain that the :number of birds placed in a shelter can survive than to place too many in a shelter and have them suffocate. Place your most valuable birds. in the best shelter with the best access to feed and water. The following table, taken from USDA Agricultural Handbook No., 234, illustrates the effects of shielding of farm poultry in barns.

Covered feed should first be used for the most valuable birds, then for the less valuable. Feed that is not covered will be contaminated by radioactive fallout and should be used only on the least valuable birds or not used at all except to prevent starvation or loss of production. Minimum survival requirements for hens in production is one - fourth pound of feed per day and for broilers is one pound for each ten birds. You should plan so that you can supply this amount with minimum time and labor requirements. Plan for Water Plan to provide the best source of water for your most valuable birds, if poss- ible and consistent with providing them the best shelter. Hens in production and broilers will require a minimum of 5 gallons of water for each 100 birds per day. Remember that these birds will be tightly enclosed and the water requirement will go up as does the space requirement. If automatic waterers are used an alternate source of power must be provided to operate the well pump in event of a power failure, This would be as necessary for natural as for nuclear disaster. If you rely on storage you should compute your water requirement for two weeks for each of the buildings containing birds and be sure you have sufficient storage capacity in each building. Covered 50 gal. drums in and around the building are good storage, and affords added farmstead fire protection. Work Schedules Even during an early period following fallout, farm families may be faced with doing certain farm chores. Radiation decays and becomes less intense with the pass- age of time. Forty -nine hours after fallout descends radiation will be only about one -one hundredth as great as at the start. It would be well for a family to plan so that they would not have to leave their shelter during this period of time. However, if absolutely necessary a person could be outside for brief periods of -5- time while radioactivity is high. You will receive iy,structions over the Emergency Broadcast System giving intensities and how long you corgi ".mod work outside during an emergency. Various public agencies have radiological non toring assignments and qualified personnel to accomplish this task. Information from these agencies will be relayed to the public via the Emergency Broadcast Sysi:eq. Do not go out of your shelter without knowing how long you can stay or the intensity of radiation in your area. We must first he concerned with the preser- vation of human lives and only secondly with the survival of our livestock. Inventory Plus Planning Equals Protection It has been determined that the majority of our rural people could survive a nuclear disaster if all would simply inventory what they have on their farm, plan to use to the best advantage what they have, learn to improve on these plans, and improve their knowledge of civil defense, Have YOU made provisions to protect YOUR family?
