CLA administration to sows reduces backfat thickness loss during the lactation period and lets to higher piglet weight at weaning.

The aims of this study were to determine whether WSI and season are associated with changes in oocyte developmental competence in sows experiencing early and late pregnancy loss.

One of the key components of survival in alternative, loose-housed farrowing systems is maternal behaviour and understanding the characteristics of sows that influence survival in such environments should be an essential component when developing new breeding indices.

Treatment with betaine improve reproductive performance of gilts and sows, and increase body weight gain of the piglets.

Diets of sows did not have major impact on glycogen pools or on mobilization of glycogen by piglets.

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.
