Gce Model Questions Vol1 2025 Agricultural Science Question 44
Practice objective / multiple choice question 44 from the 2025 Gce Model Questions Vol1 Agricultural Science examination.
A poultry farm has 800 chickens. An outbreak of Newcastle disease is detected, with an initial infection of 2 % of the birds. The disease causes a 70 % mortality rate if untreated. Before any control measures are taken, the number of newly infected birds increases by 5 % of the remaining healthy birds each day. If the farmer waits two days before starting a culling programme that removes all infected birds on the day culling begins, estimate the total number of birds that will die from the disease. Compare this with the situation where culling starts immediately (no deaths). Does the two‑day delay result in more than 50 additional deaths? Answer "Yes" or "No".
