What could be causing abortions that are not seasonal and that are not affecting a certain phase of gestation in particular?

User responses of the 333 survey on gestation length in sows reveal gestations are trending around 115.5 days.

What could be causing the abortions happening at a particular point in the gestation?

Key biosecurity messages to move dead pigs out of the clean area of the farm to the deadstock management area prior to their treatment: external deadstock container, incinerator or hydrolysis container.

Pros and cons of rendering carcass disposal systems, alkaline hydrolysis, anaerobic digestion, gasification, and homogenization.

Since 2017 the number of gilts coming into heat (with standing reflex) has gradually fallen to levels less than 50-60% of the gilts ready to be inseminated...

What can I do if the abortion rate is greater than 2% and the abortions are concentrated around a specific time of year? How can I combat seasonal abortions?

Pros and cons of the most used carcass disposal systems: burial, composting, incineration, and rendering. Impacts on environment and biosecurity.

When multiparous sows are affected, not as many need to be culled as in the case of gilts (which we saw in the last article). Generally sows will eventually show signs of heat, but with a considerable delay compared to a normal heat.

Why are there more abortions occurring in first parity sows?

Lack of estrus in gilts is a common cause for culling, which increases the need for gilts and the cost of gilts. Let's take a look a what causes anestrus:

This article lists the main non-infectious causes that can lead to irregular returns to estrus.

Porcine Parvovirus was thought to be genetically stable, but now we know that it exists in a variety of forms, raising fresh questions about its control in sow herds.

This article covers the main sow-related factors that can cause regular returns to estrus.

Pork producers and veterinarians need to be aware that the porcine parvovirus (PPV) has been evolving into new strains.

This article covers the main semen- or boar-related factors that can cause regular returns to estrus.

Biosecurity and prevention measures must take into account that as low as 5 units of ASF virus are enough to produce infection.

What are the most common mistakes when using oral fluid? How to make the most of this diagnostic technique.

Total returns to estrus should not exceed 8%; if they do, we must ask ourselves when they occur.

In this series of articles about internal biosecurity we will review McRebel and other strategies that we perform to control the movement of pathogens within the farm as we complete our daily work

Will a faster diagnosis make a significant difference in the fight against African swine fever?

We are finding more evidence of the possible role PCV-3 plays in certain reproductive problems.

This second article on the assessment of truck cleaning and disinfection describes how to carry out and evaluate the results of microbiological validation and adenosine triphosphate detection.

Why is my farrowing rate less than ideal? Use this tool to discover the potential causes. Navigate using the flowchart or use the buttons within the text to access the different parts of the tool.

Serious problems occurred much less frequently with genotype a than with genotype b. Why did the frequency of these genotypes change?

If I see a farrowing rate less than 85%, the next question I should ask is, "Are there sows returning to estrus?"

Why do my sows come into heat soon after service?

Factors related to the semen dose, the boar, or the sow can cause regular returns to estrus.

There are several factors that can cause an abnormally long estrous cycle.

What are the causes of these returns?
