Protecting the pregnant sow from PRRS: Research findings
We evaluated the efficacy of serum inoculation to immunize gilts in prevention of reproductive PRRS following late-gestation challenge with the “homologous” virus.

Effect of dietary supplementation of oregano essential oils to sows on colostrums and milk composition, growth pattern and immune status of suckling pigs
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.
Limited and excess dietary protein during gestation affects growth and compositional traits in gilts and impairs offspring fetal growth
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%.
The threonine requirement of sows increases in late gestation
Feeding a single amount of amino acids (AA) throughout gestation results in overfeeding AA in early gestation and underfeeding AA in late gestation.
Effect of N,N-dimethylglycine supplementation in parturition feed for sows on metabolism, nutrient digestibility and reproductive performance
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.
Dry sows in dynamic groups: An investigation of social behaviour when introducing new sows
The aim of this investigarion was to analyse the frequency of agonistic interactions (AI) and the lying behaviour of new and resident sows.
Dose-response effect of fish oil substitution in parturition feed on erythrocyte membrane characteristics and sow performance
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.
Does group housing increase the risk of reproduction problems in French sow herds?
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.
Reproductive performance of sows is affected by the dietary omega‐6 to omega‐3 fatty acid ratio
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.
Linseed meal during early pregnancy increases litter size in pigs
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).
Effects of extra feeding in mid-pregnancy for three successive parities on lean sows’ productive performance and longevity
The aim of this study was to investigate the long-term effects of increasing feeding allowance during mid-pregnancy in sows.
Linseed oil in the maternal diet increases long chain-PUFA status of the foetus and the newborn during the suckling period in pigs
The PUFA status in newborn piglet is directly related with the use of PUFA enriched diets during gestation and lactation.
Effect of early parturition on the reproductive performance in sows
The objective of this study was to determine the incidence of premature birth (<114 days of gestation) in the reproductive performance of sows.
Threonine requirement of sows in early, mid- and late gestation
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 supplementation with 0.8% L-Arginine between days 0 and 25 of gestation reduces litter size in gilt
Dietary L-Arginine supplementation may negatively affect gilt reproductive performance.
Post-insemination level of feeding does not influence embryonic survival and growth in highly prolific gilts
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.
