"All pigs are equal" Does the background data from juvenile Göttingen minipigs support this?

Area of Science:

• Toxicology
• Preclinical research
• Animal models

Background:

• Rats are the standard for juvenile toxicity testing, but non-rodent species like Göttingen minipigs are sometimes required.
• Limited background data for Göttingen minipigs can hinder the interpretation of juvenile toxicity studies.
• This study addresses the need for normative data in young Göttingen minipigs.

Purpose of the Study:

• To provide essential background data on Göttingen minipigs for juvenile toxicity testing.
• To characterize age-related variations in physiological and pathological parameters in piglets.
• To support the use of Göttingen minipigs as a non-rodent model in pediatric drug development.

Main Methods:

• Collection of data from 82 piglets at various ages.
• Analysis of cardiac and clinical pathology parameters.
• Evaluation of haematopoietic tissue characteristics.

Main Results:

• Normal variations and age-related changes were identified in several parameters.
• Significant age-dependent shifts were observed in cardiac function and clinical pathology.
• Haematopoietic tissue exhibited notable age-related alterations.

Conclusions:

• The presented data offer guidance for interpreting juvenile Göttingen minipig toxicity studies.
• These data can supplement concurrent study control data but not entirely replace it.
• Göttingen minipigs represent a valuable non-rodent model for pediatric toxicology, with age-specific considerations.
