Agricultural Engineering Practice Exam

The minimum recommended space requirement for adult pigs is essential to ensure their welfare and health. Typically, providing adequate space prevents overcrowding, which can lead to stress, aggression, and injuries among animals. In this case, the correct answer reflects the commonly endorsed standards for pig housing. For adult pigs, the recommended space allocation is indeed around 2.5 to 4 square meters per animal, depending on their size and growth stage. The lower figure (2.5 square meters) is often cited for lighter weight animals, while the higher figure (4 square meters) is generally used for larger breed pigs. This range ensures that pigs have enough space to lie down, stand up, turn around, and exhibit natural behaviors without unnecessary competition for space. Other choices may represent larger areas but do not align with the standard minimum requirements established by animal welfare guidelines. Providing space beyond 4 square meters might be preferable in some cases; however, the question specifically pertains to the minimum recommended standards. Hence, the listed range in the correct answer is appropriate for maintaining the welfare of adult pigs in an agricultural setting.
