Neonatal Piglet Development and Survival Strategies

Neonatal piglets face critical challenges in the transition from intrauterine to extrauterine life, with survival hinging on rapid physiological adaptation, adequate immunity and effective maternal support. At birth, piglets must thermoregulate through shivering and non-shivering mechanisms while mobilising limited energy reserves. Colostrum intake within the first hours provides essential nutrients and immunoglobulins, particularly IgG, to establish passive immunity and support gut maturation. Birth weight and order influence competitive access to teats and colostrum volume, with lower-weight or later-born piglets at greater risk of hypothermia, malnutrition and infection. The duration and management of farrowing also impact oxygenation and survival, as prolonged expulsion increases stillbirth and asphyxia rates. Nutritional strategies targeting the dam during late gestation and lactation—such as antioxidant and amino acid supplementation or optimised fibre inclusion—can enhance uterine blood flow, colostrum composition and milk yield, thereby improving piglet growth trajectories and resilience. Concurrently, environmental and management interventions, including thermal support, attentive farrowing assistance and early socialisation, mitigate stress and promote uniform development. Integrating physiological insights with practical husbandry underpins global efforts to reduce pre-weaning mortality, enhance animal welfare and secure sustainability in pork production systems.

Neonatal Piglet Development and Survival Strategies publication trend

The graph below shows the total number of articles in neonatal piglet development and survival strategies across all publications each year (not limited to Nature Index journals).

Technical terms

Colostrum: The nutrient- and antibody-rich first milk produced by the sow immediately post-partum, critical for passive immunity transfer.

Farrowing duration: The time span from the onset of labour to the expulsion of the last piglet; prolonged durations can increase stillbirth risk.

Branched-chain amino acids (BCAAs): Essential amino acids—leucine, isoleucine and valine—that support milk synthesis, immune function and neonatal growth.

Oxidative status: The balance between antioxidant defences and reactive oxygen species within an organism, influencing tissue integrity and health.

Immunoglobulin G (IgG): A major antibody class in colostrum that provides systemic passive immunity to neonates against pathogens.
