Should Pigs be Eating Their Poop or Not

When pigs eat their poop, it gives them another chance to process the undigested nutrients. However, this is not good when it’s done often.

If a pig does it all the time, it’s at risk of getting a gastrointestinal infection.

study discovered that sanitation is connected to the prevalence and risk of gastrointestinal parasites that cause helminth or worm infection among pigs.

Thus, regular disposal of litter and manure on pig pens is advised since they usually excrete in an area that is close to where they live and feed.

Pigs prefer to lie down in dry, warm areas while they excrete in wet, cool places nearby. They usually poop on the floor that is covered by water.

Therefore, they make it a habit to drop their poop near the drinking area.

In this setting, the water that they drink will be mixed with their poop. This situation will lead to the spread of the infection if there is more than one pig in a pen. So, the upkeep of their pens is essential.

In the findings of the study, young pigs are mostly affected by the gastrointestinal parasite. But those that are older than five months have developed immunity. Still, they have some worms inside of their bodies. They have fewer than the young ones.

What to Do with Pig Poops?

As the pig poop piles up, the odor becomes stronger, and sanitation becomes a concern. It’s not going to be a problem if you know what to do.

1. Composting

Composting is the option for those who raise pigs indoors or in a concrete building. The manure is removed from these areas then taken to the composting site. Pig poop contains similar germs that are found in human waste.

So, these germs are hazardous, and it’s necessary to compost before using the pig poop as a fertilizer. This process also cuts down the odor coming from the poop.

For this purpose, you need to cover the composting site. Farmers do it since they grow edible crops. However, you can directly use it as a fertilizer on the pasture that other animals feed on.

2. On-Pasture Pig Poop Management

This method is ideal for those who manage their pigs on pasture. The proper way of utilizing manure and monitoring the soil’s health is crucial to enhance the condition of the area. Depending on the size of the pasture, you may leave the poop on it as it is.

In a dense place packed with numerous pigs, you should spread the poop rather than just wait for it to decompose. You may do it through a harrowspreader, or four-wheeler with a chain link. These things can make it easier to spread pig poop.

Yearly checking on the soil is recommended, so you’ll know other nutrients that it needs. You must know that pig poop can’t supply all the nutritional requirements of the soil.

3. Stockpiling

It’s an option for people who raise their pigs indoors or in a concrete place. A large commercial pig farm is the perfect place to practice stockpiling poop. This establishment has enormous holding tanks or lagoons for this procedure.

Stockpiling involves bacteria turning pig poop into solid and liquid forms. Then, they are sold as fertilizers or fuel sources. A small-scale operation of stockpiling is also possible.

The result can be sold as a soil additive to local nurseries or greenery. Farmers will also be interested in it as they utilize it as fertilizer.

If you stockpile, you have to choose the right location for storage. It must be far enough from the dwellings to prevent inconvenience. You also have to consider the weather to achieve your goals.

See to it that when the wind blows, the poop won’t go in the direction of your house or someone else’s.

It’s also good to cover your stockpile due to odor concerns. You may also make a roof for it so the odor will not drift.

4. Removal process

Removing pig poop is linked with stockpiling. To save some effort, it’s wise to stockpile the poop before removing it in a large amount. You can do it yourself and sell the byproduct.

If you want to trouble yourself, you can hire a company to do the process for you.
