The key causes of lameness in sows
Understanding potential causes of lameness can help reduce the levels of lameness in the breeding herd and thus improve farm productivity and sow welfare.

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.
The use of oxytocin in liquid semen doses to reduce seasonal fluctuations in the reproductive performance of sows
On the basis of the presented results, it should be noted that the use of oxytocin into insemination doses improves the farrowing rate and other parameters of the reproductive performance of sows.
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.
