Explore fundamental concepts of animal disease management relevant to animal husbandry, focusing on prevention, control, and practical farm approaches. Sharpen your understanding of strategies that promote livestock health and productivity.
Which practice best illustrates biosecurity measures to prevent disease entry into a piggery?
Explanation: Restricting visitor access limits potential disease introduction from humans, supporting biosecurity. Feeding kitchen scraps risks introducing pathogens through contaminated foods. Keeping animals outdoors without controls does not address disease vectors. Mixing species freely can spread multi-host diseases between animals.
A dairy farmer notices sudden coughing among several cows; which is the most likely method of disease transmission in this scenario?
Explanation: Coughing can rapidly spread respiratory diseases through airborne droplets. Genetic inheritance is not involved in contagious outbreaks. Mineral deficiency causes health issues but not infectious spread. Improper hoof trimming is unrelated to respiratory disease transmission.
Why is it important to follow recommended vaccination schedules in poultry farming?
Explanation: Vaccination schedules create herd immunity, protecting both vaccinated and unvaccinated birds from disease outbreaks. Vaccination does not directly affect egg size, feather coloration, or molting speed, which are influenced by genetics and nutrition.
When introducing new goats to an established herd, which best practice helps prevent the spread of disease?
Explanation: Quarantining allows observation for signs of disease before exposure to the main herd. Feeding more grain is a dietary adjustment, not a disease control measure. Sharing grooming tools and immediate mixing can facilitate disease transmission.
A farmer observes reduced appetite, fever, and discharge in several sheep. What are these examples of?
Explanation: Fever, reduced appetite, and discharge are symptoms signaling illness and help with early disease detection. These are not traits for breeding or genetic improvement. Breeding behaviors involve mating-related actions, while normal seasonal changes typically do not include clinical signs like fever.
