Palygorskite dietary supplementation effects on back fat mobilization, leptin levels and oxidative stress in sows
The use of palygorskite in sow diets reduces oxidative stress in gestating sows.

Clinical case: Increase of returns in summer and low annual prolificacy
The farm reports a problem of low prolificacy (mean annual live births of 11.91) and low fertility in summer, with a marked increase in acyclic returns.
Relationships between ovulation rate and embryonic and placental characteristics in multiparous sows at 35 days of pregnancy
A high avulation rate results in an moderate increase in the number of vital embryos at day 35 of pregnancy, but compromises development in the surviving embryonic/placental units, suggesting that the future growth and survival of the embryos might be further compromised.
Observations of sows and piglets housed in farrowing pens with temporary crating or farrowing crates on a commercial farm
The current study demonstrated that the farrowing system design can influence sow behaviour, with pens allowing for more interactions between sows and their piglets.
Essential fatty acid supplementation during lactation is required to maximize the subsequent reproductive performance of the modern sow
A minimum dietary intake of both α-linolenic and linoleic acid is required for the modern lactating sow to achieve a maximum reproductive outcome.
Is body condition the right tool to adjust feeding in pregnant sows?
Energy intake based on body condition differs greatly from the energy adult sows require. Moreover, the NRC clearly overestimates the sows' maintenance requirements.
Uterine and placenta characteristics during early vascular development in the pig
This work establishes fundamental time points in placenta development corresponding to fetal growth and microfold formation that may influence fetal growth and impact fetal survival.
Conjugated linoleic acid during late gestation reduces the fat content in the colostrum and increases IgG
Colostrum production and immunoglobulin concentrations to conjugated linoleic acid during late gestation.
Interval from last insemination to culling: Culling reasons from practise and the correlation with longevity
This study showed the potential to select on longer interval from last insemination to culling in days and thereby select against sows to be culled within the reproduction, locomotion, accident, general disorder and peri-partum cull class and to be culled at the end of a parity.
Effect of PCV2 infection on reproduction: disease, vertical transmission, diagnostics and vaccination
The immune status of farms is quite possibly different from the one they had before piglets mass vaccinations.
Gestational heat stress alters postnatal offspring body composition indices and metabolic parameters in pigs
Heat stress during the first half of gestation altered metabolic and body composition parameters during future development and in biological responses to a subsequent heat stress challenge.
Effects of dietary 0.5% aniseed extract on milk yield of sows and their offspring
Sow dietary supplementation with aniseed extract during late gestation and lactation improves milk yield and litter performance.
Outcomes of gestation length in relation to farrowing performance in sows and daily weight gain and metabolic profiles in piglets
In conclusion, premature births increase the number of intra-partum deaths and result in lower birthweights, the presence of apnoea, and severe metabolic alterations in piglets.
Moderate changes in the nutrition of gestating sows have no harmful effects on the development of their offspring
Diet deprivation and subsequent over-allowance during gestation does not impair postnatal piglet growth.
Relative prolactin-to-progesterone concentrations around farrowing influence colostrum yield in primiparous sows
In conclusion, a greater PRL/P4 ratio 24 h prepartum, characterized by lower P4 concentrations and a trend for greater PRL concentrations peripartum, led to increased colostrum yield in primiparous sows.
Effects of space allocation and parity on selected physiological and behavioural measures of well-being and reproductive performance in group-housed gestating sows
Our results suggest that at least at the chosen stocking densities, parity and space allocation have minimal effect on a number of commonly-used welfare measures.
