Many farmers, especially beginners, think that the more frequently you deworm pigs, the healthier they become. But this is not always true. Deworming is like medicine; you want to give it at the right time and in the right amount, not overuse it.
From my experience, healthy adult pigs usually do not need to be dewormed every month. Most adult pigs in Asaba do well on a routine of deworming every three to six months.
This might seem counterintuitive, but worms do not multiply overnight. Overusing dewormers can lead to unnecessary stress on the pigs’ organs and even cause drug resistance. On my farm, I had a sow that was dewormed every two weeks for no reason, and she developed mild digestive issues. After consulting a vet, I adjusted her schedule, and her health stabilized.
For young pigs, the story is different. Piglets and weaners are more vulnerable because their immune systems are still developing. In my experience with several farms in Ibusa and Okpanam, weaners often require their first deworming at around six to eight weeks old.
Depending on the environmental risk and worm pressure, a second deworming may be needed within the next month. This means that in rare situations, you could deworm young pigs twice in a month, but this should be done only under veterinary supervision. The key is that this is based on need, not habit.
I’ve also seen cases where heavy parasite outbreaks occur in a farm, often after rainy seasons when the environment is humid, and worms thrive. In such situations, a vet might recommend a second dose within three weeks to curb the infection. This is why it is important not to treat deworming like a monthly ritual but as a strategic response to the pig’s health and environment. On my farm, I maintain records of each pig’s treatment date, so I always know which pigs need follow-up and which don’t. This record-keeping alone has saved me thousands of naira in unnecessary medication.

Understanding Pig Deworming Dosage
Another critical aspect many farmers overlook is pig deworming dosage. Giving too little may not kill the worms, while giving too much can harm the pig. On my farm, I always weigh each pig before administering any medication. For example, I once had a batch of growers weighing around 50 kilograms each.
For a commonly used anthelmintic like Piperazine, the recommended dose is about 10 grams (10 ml) per 50 kilograms of body weight when given in feed or water. Administering this dosage correctly ensures that the worms are eliminated without harming the pigs.
Dosage also varies depending on the type of deworming medicine. I have used Fenbendazole for roundworm infestations and Levamisole for whipworms. Each medicine has its own recommended dosage and method of administration. If you are unsure, always consult a vet. On one occasion, a neighboring farmer administered Levamisole without checking weights, and some pigs became lethargic due to an overdose. From that experience, I learned that even effective medicines must be handled with care.
Developing a Practical Pig Deworming Schedule
Based on my experience, here is how I approach a pig deworming schedule in Asaba. I always start by evaluating the age of the pigs, the environmental conditions, and previous worm issues. For piglets, the first deworming happens at six to eight weeks. Depending on the worm pressure, a second deworming might occur around 10 weeks.
Growers are then dewormed every eight to twelve weeks. Adult pigs, including sows, are treated two to three times a year, with a dose administered about two to three weeks before farrowing to ensure piglets are not exposed to worms early in life.
I’ve applied this schedule on multiple farms in Delta State, and the results are clear. Pigs maintain consistent growth, fewer cases of diarrhea occur, and overall mortality rates drop significantly. The key is consistency. You may have excellent feed and housing, but if worms are allowed to thrive, your pigs will not perform well.
Natural Deworming Methods and Complementary Practices
Many farmers ask if pigs can be dewormed naturally. Over the years, I’ve experimented with a few options, and here’s what I’ve found. Feeding pigs pumpkin seeds and crushed papaya seeds can help reduce mild worm loads. Garlic is also sometimes added to feed as a natural dewormer. While these methods can be supportive, they cannot replace professional medicines, especially in cases of heavy infestations.
On my farm, I use natural supplements as a complementary measure alongside conventional deworming. For instance, after treating piglets with an anthelmintic, I include small amounts of pumpkin seeds in their feed. This approach not only improves worm control but also supports digestion and general immunity.
I also emphasize environmental hygiene. Cleaning pig pens regularly, removing feces, and ensuring dry bedding significantly reduce worm exposure. I’ve seen farms that rely solely on medications but neglect hygiene, and still struggle with reinfection. In my experience, combining proper deworming, natural supplementation, and strict hygiene yields the best results.
Choosing the Right Pig Deworming Medicine
The market in Nigeria offers several effective de-wormers, including Fenbendazole (Safe-Guard), Ivermectin injectables, Levamisole, and Albendazole. I have personally used all these medicines on my farm, depending on the type of worms detected. The important point is to always select species-appropriate medicines. I’ve seen cases where farmers use cattle de-wormers on pigs, which can be dangerous because the dosage and composition are not suited to swine.
Each medicine also has withdrawal periods, which are the time you should wait after treatment before selling the pigs. For example, Albendazole may require a few days of withdrawal. Ignoring this can result in unsafe meat reaching the market, which can harm your customers and your reputation.

Conclusion: Making Smart Decisions on Deworming Frequency
So, how many times should you deworm a pig in one month? The simple answer is that healthy adult pigs generally do not require monthly deworming. Young pigs and those in worm-heavy environments may need a second treatment within the month, but only under veterinary guidance. Deworming is most effective when applied strategically based on age, health, and environmental conditions, rather than blindly following a monthly routine.
From my decade of experience in Asaba, I can tell you that farms that take worm management seriously, record treatments, use proper dosages, and maintain clean pens enjoy faster growth, healthier pigs, and more profits. Deworming is not just a task to check off; it’s part of a broader approach to responsible, profitable pig farming.
If you are serious about running a successful pig farm in Asaba, consider creating a structured deworming plan with your veterinarian. Factor in age, worm exposure, and environmental conditions. Track every treatment, adjust as necessary, and complement medicines with natural supplements and good hygiene practices. This approach will ensure that your pigs grow fast, stay healthy, and that your investment yields the best possible returns.
Remember, effective deworming is not about how many times you give medicine in a month it’s about giving it at the right time, in the right dose, for the right reason. When you master this, your pigs will thank you with better health and higher weight gains, and your farm will flourish in the competitive market of Delta State.
