Dynamic group gestation with weight monitoring
Continuous monitoring of sow weight has significantly improved feed use efficiency and sow longevity.
Tip: A stamp to save piglets
This tip uses a stamp to mark the sows that we should pay more attention to during farrowing.
Post cervical artificial insemination in gilts
The use of Post Cervical AI in gilts remains a challenge due to the difficulty of passing the catheter through the cervix. In addition, the time required for PCAI compared to multiparous sows tends to be longer.
The Signs of farrowing: Physiology and sow behaviour
Understanding the farrowing process and recognizing the signs for the different stages of birth, help us to develop management plans to improve the likelihood for live born piglets.
What fractions of the ejaculate should I include when preparing artificial insemination doses?
Currently, only the sperm-rich fraction is used. This article analyzes the possible use of the other fractions.
Who has better production indexes- Spain or the United States? (2/2)
We continue our comparison of production data between sow farms in Spain and the United States. This time we focus on replacement rate, pre-weaning mortality, and weaning weight.
Post farrowing fever control to maximize feed intake in sows during lactation
Why is it important to take sow temperatures after farrowing? How does feed intake affect litter size?
Precision ultrasonography in sows: There’s much more than pregnancy check!
Here's how ultrasound can be used to visualize ovarian structures, assess the state of puberty, and diagnose ovarian pathologies.
Do I have culled pregnant sows?
If my farrowing rate is low but I don't have empty sows or abortions, I must consider the culled pregnant sows.
Causes of increased number of culled pregnant sows
The most frequent problems are reproductive and locomotive. What should I do if the percent among sows serviced is greater than 2%?
Seasonality in mating outcomes: A review
Each farm should analyze its historical data to quantify the effect of seasonality on its farrowing rate and prolificacy.
Causes for an increased number of empty sows
What should I do if the percentage of empty sows among the sows serviced is greater than 1%?
Causes of abortions occurring at non-specific points in the gestation
What could be causing abortions that are not seasonal and that are not affecting a certain phase of gestation in particular?
Is gestation length changing in sows?
User responses of the 333 survey on gestation length in sows reveal gestations are trending around 115.5 days.
Post-insemination management guidelines for swine
To conclude this series of articles, swine reproduction and artificial insemination specialist Javier Gil explains the importance of proper post-service management in terms of when to move sows and how to feed them.
