Reproductive performance of sows can be predicted by high numbers of pigs born alive in parity one
High PBA in parity 1 can be used to predict that a sow will have high reproductive performance and lifetime performance.

Insemination with no hands
This trick consists in using a spring for holding the semen bag during the insemination.
Magnesium supplementation improves digestibility and reproductive parameters in sows
Magnesium supplementation can increase reproductive performance in adult sows.
Stimulate the sows as much as possible during their mating (G-spot)
Mating the stimulated sows eases the sperm transport to the oviduct, where they meet the ova.
Collection of oral fluid from individually housed sows
These baseline results suggest that oral-fluid samples can be collected from individually housed sows, but that further studies on the optimization of oral-fluid collection in the sow unit (gestation and farrowing) would be of value.
Assisted farrowing - indoor breeding
This video from BPEX explains how to assist sow farrows.
NET energy system for gestating and lactating sows (2/2)
The results show that digestibility of the same diets is indeed higher for gestating and lactating sows than it is for growing pigs.
NET energy system for gestating and lactating sows (1/2)
Making use of the NET energy system for sows to formulate feeds makes it possible to achieve a smooth transition from gestation to lactation diets, which makes the transition period around farrowing easier for the sows.
Feeding programs for sows could be established on a metabolic states and hormonal profile basis
Insulin, ghrelin and leptin could be used as biomarkers to detect situations resulting in a poor energy balance.
Dietary long-chain polyunsaturated fatty acids from protected fish oil effects on the joints health in sows
The dietary fish oil inclusion may prevent lameness appearance in sows.
Farrowing pens for the future
To Jyden it is primarily essential that the design is focused on a farrowing pen (for loose sows) with the possibility to use the integrated protection wings – and not just to open a traditional farrowing crate.
Encapsulated porcine semen: semen preservation, release kinetics, sperm transport, and results in the farm
Sows inseminated with encapsulated semen had more sperm cells concentration at the site of fertilization.
Control of feeding with a chart wrapped around the water pipe
The goal is to record the sows' feeding level when fed manually.
Pregnant sows: Notes on the card wrapped in a plastic bag
Wrap the sow's card in a transparent plastic bag and write down on it the information with a thick marker.
Effect of feeding on hormones related with feed intake in reproductive sows
Insulin, acylated ghrelin and cortisol could be used as biomarkers to detect situations resulting in a poor energy balance in order to improve handling programs.
Influence of permanent use of feeding stalls as living area on ammonia and greenhouse gas emissions for group-housed gestating sows kept on straw deep-litter
Keeping group-housed gestating sows on partly straw bedded floor with permanent access to the concrete feeding stalls compared to fully straw bedded floor did not significantly influence animal performance and NH3-emissions, and decreased CO2eq-emissions.
