Effect of dietary supplementation of n-3 fatty acids and elevated concentrations of dietary protein on the performance of sows
Dietary supplementation of n-3 fatty acids during lactation improved the growth of nursing piglets.

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.
Phenotypic and Genetic Correlations between Gilt Estrus, Puberty, Growth, Composition, and Structural Conformation Traits with First Litter Reproductive Measures
The objective was to estimate correlations of gilt estrus, puberty, growth, composition, and structural conformation traits with first litter reproductive measures.
Effects of fibre and floor space allowance on group kept dry sow well-being
Sow welfare may be directly related with floor space allowance and dietary fibre.
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.
The influence of n-3 polyunsaturated fatty acids in the feed of the sow on parturition characteristics and piglet viability
Dietary n-3 polyunsaturated fatty acids may affect parturition traits 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.
Satiating properties of diets rich in dietary fibre fed to sows as evaluated by physico-chemical properties, gastric emptying rate and physical activity
The use of ingredients with high DF content in sow diets may reduce the physical activity of the sow.
Body reserve mobilization during lactation in first parity sows and its effect on second litter size
The aim of this study was to evaluate the influence of sow body reserves at weaning and body reserve losses during the first lactation on the second litter size (SLS). A number of 1222 females which reached the second parity without failures such as return to estrus after insemination, abortion or failure to farrow, were analyzed. Measurements of body weight (BW), backfat thickness (BT) and body condition score (BCS) were taken within 24 h after farrowing and on the weaning day.
Relationships between backfat thickness and reproductive efficiency of sows: A two-year trial involving two commercial herds fixing backfat thickness at breeding
In this study, we established whether controlling backfat thickness at breeding over a long time period can result in optimized reproductive performance in sows.
Impact of an extended photoperiod in farrowing houses on the performance and behaviour of sows and their litters
The effects of an extended photoperiod around parturition and throughout lactation on performances of primiparous sows and their piglets were studied.
