The pictures below refer to a production system in pigs - NSC Agricultural Sciences - Question 3 - 2023 - Paper 1

An example of the pig production system represented in picture B is the Free range system. This type of system allows pigs to roam freely in a natural environment, providing them with more space and access to outdoor areas.

The animal handling facility identified in picture A is a Farrowing pen/crate. This facility is designed to house sows and their piglets safely, ensuring proper care and management.

One reason for housing pigs in a farrowing pen is that it prevents cannibalism. The design of the pen ensures that the mother sow cannot accidentally harm her piglets during nursing.

Two factors that contribute to increased production as seen in picture A include:

1. Nutrition/feed management: Ensuring pigs receive balanced and adequate nutrition to support growth and reproduction.
2. Environment/housing/sheltering: Providing a controlled shelter that protects pigs from environmental stresses and promotes their well-being.
