Summary

Reducing preweaning mortality in piglets, especially intra-uterine growth-restricted (IUGR) ones, requires optimizing sow nutrition and implementing post-farrowing assistance. Strategies include environmental control, farrowing supervision, and ensuring adequate colostrum intake for piglet survival.

Area of Science:

Animal Science
Reproductive Biology
Swine Production

Background:

High preweaning mortality in piglets is linked to low birth weights and intra-uterine growth restriction (IUGR).
IUGR in piglets often results from insufficient nutrient transfer in hyperprolific sows.
Sow energy status at farrowing impacts stillbirth rates, and piglets may struggle to consume enough colostrum.

Purpose of the Study:

To review current strategies for enhancing fetal development and reducing preweaning mortality in piglets.
To highlight the importance of sow nutrition and management for improving newborn piglet survival.
To discuss interventions that increase colostrum yield and piglet immunoglobulin intake.

Main Methods:

Literature review of nutritional and management strategies for sows and piglets.

Keywords:

Gestation Lactation Management Mortality Sow

Analysis of factors affecting fetal development, birth weight, and colostrum production.

Evaluation of post-farrowing assistance techniques for newborn piglets.

Main Results:

Sow nutritional strategies before and during gestation can improve fetal development.
Sow energy status at farrowing is critical for reducing stillbirths.
Oxytocin administration can prolong the colostral phase, increasing immunoglobulin supply.

Conclusions:

Optimizing the farrowing environment, supervising farrowing, and providing post-birth assistance are crucial for piglet survival.
Techniques like cross-fostering and artificial milk can supplement piglet nutrition.
Further research is needed to maximize outcomes in piglet performance and survival through advanced feeding and management strategies.
