The administration of altrenogest in late gestation is an effective and safe method to prevent early parturition and can counteract the reproductive losses because of premature farrowing, which may occur in a substantial part of the farrowing events.

Maternal seaweed extract and fish oil supplementation from day 109 of gestation until weaning stimulates growth performance and starter feed intake in weaning pigs.

We evaluated the efficacy of serum inoculation to immunize gilts in prevention of reproductive PRRS following late-gestation challenge with the “homologous” virus.

Supplementing sow diets with 250 mg/kg of oregano essential oils during gestation and lactation did not affect the growth potential of and immune responses in suckling piglets.

Gestation diets containing protein at 50 and 250% of recommendations led to marked changes in protein and fat metabolism in gilts resulting in fetal growth retardation of 15%.

Feeding a single amount of amino acids (AA) throughout gestation results in overfeeding AA in early gestation and underfeeding AA in late gestation.

The current pilot study assessed the influence of N,N-dimethylglycine (DMG) on insulin sensitivity, glucose and fat metabolism, nutrient digestibility and reproductive performance of sows in the peripartal period.

The aim of this investigarion was to analyse the frequency of agonistic interactions (AI) and the lying behaviour of new and resident sows.

Osmotic resistance of erythrocytes was not altered by increasing amounts of n-3 PUFA, whereas oxidative stability of erythrocytes, as well as oxidative parameters in plasma, were affected.

The aim of this study was to investigate reproductive performance and possible reproductive problems (late estrus, infertility, reasons for culling) in herds with either group‐housed or individually housed pregnant sows. In a second analysis, we evaluated the effects of different group housing systems.

An experiment was conducted to determine the effects of the omega‐6 (n‐6) to omega‐3 (n‐3) fatty acid ratio in sow diets on reproductive performance and immunoglobulin profiles in sow colostrum and piglet serum.

To determine how feeding linseed meal (LSM) during gestation influences litter size, placental weight, and piglet growth, sows (n = 30) received a phytoestrogen-free Control diet throughout gestation; 12.5% LSM diet throughout gestation (LSM114); or 12.5% LSM diet from day 1 to day 15 of gestation and control diet until parturition (LSM15).

The aim of this study was to investigate the long-term effects of increasing feeding allowance during mid-pregnancy in sows.

The PUFA status in newborn piglet is directly related with the use of PUFA enriched diets during gestation and lactation.

The objective of this study was to determine the incidence of premature birth (<114 days of gestation) in the reproductive performance of sows.

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.
