Final answer:
The best method to reduce porcine stress syndrome is through careful selection, which aims to eliminate the genes responsible for this condition from the breeding population.
Step-by-step explanation:
The best method to reduce porcine stress syndrome is careful selection. Porcine stress syndrome, also known as malignant hyperthermia, is a genetic disorder in pigs that is characterized by hypermetabolism and a rapid increase in body temperature, often triggered by stress, certain anesthetics, or extreme exercise. It can be fatal if not managed properly. To reduce instances of this syndrome, breeders must employ careful genetic selection to ensure that they are not breeding pigs that carry the genes responsible for this condition. This proactive approach involves eliminating affected individuals from the breeding population to decrease the prevalence of the disorder over time.
