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.

Trouble-shooting herd fertility problems
Let us assume that the expected farrowing rate and live-born litter sizes are 90% and 12.5, respectively, but that current performance is 82% and 11.3, respectively. This means that too many sows are bred but failing to farrow and those that farrow are having fewer pigs.
Innovation awards for SonoCheck and QuigTag
SonoCheck is a newly-developed device for automatic pregnancy checking of sows in group housing
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.
Farrowing programming II
The gestation period in the majority of sows is usually around 113 to 115 days. However, a percentage of sows can farrow normally up to 3 days before or after.
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.

Benefits of synchronizing ovulation with porcine luteinizing hormone in a fixed-time insemination protocol in weaned multiparous sows
Double insemination of multiparous sows, timed to coincide with optimal sow fertility, may improve litter size.
Organization of the replacements II
In previous chapters we have looked at the importance of maintaining the ideal parity profile within each batch.
Effects of space allowance and floor type on gaseous emissions from gestating sows
This study aims to compare emissions of pollutant gases (NH3, N2O, CH4, CO2) from gestating sows kept on straw based deep litter depending on the space allowance and the floor type.
Gestation in stalls
This month we are setting you a new test, in this case on the welfare of sows accommodated in stalls during gestation.
Sow parity structure (I)
One of the main goals for a sow herd is to achieve a correct homogeneity of the productive batches.
Jyden Bur: Free stall system for the European market
As of 2013, the European Union has made new requirements for gestated sows. The ordinary static crate will be phased out by law but there are other solutions. A high level of efficiency, an improved working environment and more animal welfare is the outcome of the popular and flexible gestation crate, JB5000 from Jyden Bur – a Danish company with an international perspective.
Conditions for gestating sows in groups
A new instalment of the test on animal welfare in swine herds. This test evaluates your knowledge on the welfare of gestating sows allotted in groups.
