Explore essential concepts of livestock health care, focusing on disease prevention, nutrition, and animal husbandry best practices. This quiz is ideal for those seeking to strengthen their understanding of management strategies in agricultural settings.
Which method is most effective in minimizing the spread of infectious diseases among livestock housed together?
Explanation: Quarantining new animals helps prevent introduction of diseases to the existing herd. Feeding animals extra grain improves nutrition but does not address disease control. Painting hooves is useful for treating hoof problems but not infectious disease. Adding salt to water manages mineral intake, not infections.
Why is it important to provide balanced rations containing essential vitamins and minerals to dairy cattle?
Explanation: Balanced rations ensure cows get necessary nutrients for health and high milk yield. Reducing feed costs may compromise nutrition. Increasing wool length is not relevant for dairy cattle. Loud vocalizations do not indicate health or productivity.
What is a reliable way to control internal parasites in sheep on a pasture-based system?
Explanation: Rotational grazing disrupts parasite life cycles and reduces exposure. Constant confinement can increase disease stress. Daily shearing isn't related to parasite control. Salt blocks meet mineral needs but do not treat internal parasites.
When should calves typically receive their initial vaccination against clostridial diseases?
Explanation: The first vaccine dose is usually given at 2–3 months old when maternal antibodies wane. Right after birth is too early. One year of age and after second lactation are too late, leaving the animal unprotected.
Which observable sign most likely indicates a goat may be suffering from a respiratory infection?
Explanation: Coughing is a common symptom of respiratory infections. Increased feed intake, shiny coat, and high milk yield generally indicate good health, not illness.
