Current NRC (1998) recommendations for amino acids (AA) do not account for different requirements in early vs late gestation due to changes in metabolism; recovery of body tissue from previous lactation, and fetal, gut and mammary growth in late gestation. These increases in gut and mammary tissue and gut mucin suggest that there is a higher requirement for threonine (THR) in late gestation.

Dietary L-Arginine supplementation may negatively affect gilt reproductive performance.

This study was designed to investigate the influence of a high level of feeding during early gestation on embryonic survival and variability of embryonic development in hyperprolific LW gilts.

Double insemination of multiparous sows, timed to coincide with optimal sow fertility, may improve litter size.

This study aims to compare emissions of pollutant gases (NH3, N2O, CH4, CO2) from gestating sows kept on straw based deep litter depending on the space allowance and the floor type.

Multiparous sows enter easily to the electronic feeders than primiparous without effects on feeder aggressions

Feeding pregnant sows amounts above the requirement during the period of secondary muscle fiber formation affected muscle fiber characteristics

Extra lipid supplies before farrowing may improve piglet survival

The use of sow dietary CLA supplementation through late gestation and lactation may improve piglet immunity and health status after weaning

The MUFA dietary supplementation during the first half of gestation may reduce the incidence of low birth weight

High feed intake and low plasmatic Tryptophan levels during the lactation may be directly associated to sow reactivity

Higher feed intake during lactation let to improve sow and litter performance

The dietary inclusion of wheat straw during the gestation phase improves sow and litter productivity.

The expression of the responsible genes for trapping, release and storage of fatty acids and glucose may be modulated by altering n-6:n-3 ratio of the diet in pregnant sows

Glucose curve characteristics and insulin sensivity may affect litter performance and sow productivity

The inclusion of high levels of dietary fibre during the gestation phase does not affect sow reproductive and productive performance
