Final answer:
Dusting, dipping, or spraying the herd with insecticides at least once a month is NOT a good means of preventing illness in animals.
Step-by-step explanation:
Dusting, dipping, or spraying the herd with insecticides at least once a month is a good means of preventing illness in animals. This helps to control and eliminate parasites such as ticks, fleas, and mites that can transmit diseases to the animals. Regular trimming of hooves is also important to prevent issues such as hoof infections and lameness.
Vaccination of all members of the flock is another crucial measure to prevent illness. Vaccines stimulate the immune system of the animals to protect them against specific diseases.
Minimizing stress for the flock is also important for preventing illness. Stress weakens the immune system of animals, making them more susceptible to diseases. Providing a comfortable and low-stress environment, proper nutrition, and avoiding overcrowding can help in minimizing stress and keeping animals healthy.
