Visceral organs (VO) are essential for their role in the metabolism and distribution of consumed nutrients  as well as other life functions in animals. Two experiments were conducted to assess the natural longitudinal changes that the VO undergo from birth through 150 kg body weight (BW). Results showed that both absolute and relative measurements (weight, volume, and length) of VO were dependent on the BW (age) of the pig.

Data was collected by serial slaughter of pigs. Data were then analyzed based on the age and bodyweight of the pigs.

Further, and more detailed, information about data collection, handling, and analysis is contained in the manuscript in which the data is published in the Journal of Animal Science (JAS-2021-5659).
