Parasites are organisms that live in or on another organism, known as the host, and feed off them. They can cause serious diseases and infections, and some can even modify the behaviour of their host. They are often transmitted by physical contact, the faecal-oral route, or vectors such as ticks and biting flies. Animals infected with parasites may experience a reduction in feed intake, protein loss, and tissue damage within the digestive tract. This can lead to decreased growth, milk production, and reproductive efficiency. However, a balanced diet and a healthy immune system can help prevent and control parasite infections. For example, increasing protein levels in the diet can help sheep become more resilient to parasite infections. Additionally, some animals may instinctively consume medicinal plant-based compounds to protect themselves from parasites.

What You'll Learn
A balanced diet can help prevent parasitic infections
A balanced diet is essential for overall health and can indeed help prevent parasitic infections. While parasites come in many forms, including helminths (worms), arthropods (lice, ticks, mosquitoes, etc.), and protozoa, a healthy diet can be a powerful tool in protecting against them.
Firstly, a balanced diet contributes to a robust immune system, which is our body's natural defense mechanism against parasites. A strong immune system can help prevent and fight off parasitic infections, reducing their impact on the host. For example, young, growing animals will prioritize maintaining body protein and acquiring immunity to parasites, as seen in research by Coop and Kyriazakis in 1999.
Secondly, certain dietary choices can directly impact parasite prevention. For instance, increasing protein levels in the diet has been linked to a reduction in parasitic infections. Research has shown that higher protein intake enables sheep to become more resilient to parasite infections. Additionally, specific plant-based compounds have been found to possess medicinal properties that can help deter parasites. For example, the bitter pith of the Vernonia amygdalina plant, which has antimicrobial effects, has been observed to help a sick chimpanzee recover quickly.
Furthermore, maintaining a healthy weight through a balanced diet is crucial. Obesity can increase the risk of certain parasitic infections, such as those transmitted by vectors like mosquitoes, which are more attracted to individuals with higher body mass indexes. By maintaining a healthy weight, the risk of vector-borne parasitic infections can be reduced.
Lastly, a balanced diet can help provide the necessary nutrients to support overall health, which is crucial when dealing with parasitic infections. For example, adequate vitamin and mineral intake can help maintain the strength and integrity of the skin and digestive tract, creating a less favorable environment for parasites.
In conclusion, a balanced diet is a fundamental aspect of parasite prevention and overall health. By supporting the immune system, providing specific nutrients, and maintaining a healthy weight, individuals can reduce their risk of parasitic infections and promote overall well-being.

Increased protein intake can improve resilience to parasites
A parasite is an organism that lives in or on another organism (the host), taking its nourishment from the host. There are over 1,000 species of parasites affecting domesticated animals worldwide, and they can be classified as either external or internal parasites. External parasites irritate the skin by biting, embedding, etc., causing diseases like mange and scabies, which affect the animal's health and growth. On the other hand, internal parasites live in the blood or tissues inside the host's body and can enter when the host swallows contaminated food or water.
When animals are infected with parasites, their feed intake decreases, and they experience protein loss and tissue damage within the digestive tract, leading to decreased growth, milk production, and reproductive efficiency. Increasing metabolizable protein in the diet during protein-scarce periods can help animals become more resilient to parasite infections and may contribute to developing immunity. Research has shown that increasing metabolizable protein by 20-25% can improve a sheep's ability to manage parasites.
Protein supplementation is especially beneficial for ewes rearing multiple lambs in poor body condition and young, growing lambs with the potential for rapid growth. Various protein supplements have been studied, including soybean meal, fish meal, cottonseed meal, urea, and dried distillers grains with solubles (DDGS). These studies have also observed a reduction in fecal egg counts over time with increased dietary protein levels.
Additionally, a study on caterpillars infected with parasites found that those fed high-protein diets survived longer, and in greater numbers, than those with less protein. The mechanism behind this was attributed to osmotic stress rather than an enhanced immune system. The higher protein levels in the caterpillar's blood drew water out of the bacterial cells through osmosis, increasing the concentration of necessary molecules such as sugars and amino acids within the bacteria.
While the impact of diet on host-parasite interactions requires further research, these findings suggest that increased protein intake can play a role in improving resilience to parasites in animals, particularly in the case of gastrointestinal parasites.

Animals prioritise protein maintenance during parasite infections
Diet is important when animals are infected with parasites because parasites can cause a reduction in feed intake, leading to a scarcity of nutrients. As animals react to parasite infections and the scarcity of nutrients, they tend to prioritise maintaining body protein, then acquiring immunity to parasites, followed by protein gain, and maintaining body lipids or body condition.
According to research by Coop and Kyriazakis (1999), young, growing animals will tend to focus on maintaining body protein, then acquiring immunity to parasites, followed by protein gain and then maintaining body lipids or body condition. For reproducing animals, they state that maintenance of body protein is the priority followed by pregnancy or lactation, then expression of immunity and body condition.
Research has also shown that increasing the metabolizable protein in the diet during times of protein scarcity enables sheep to become more resilient to parasite infections. This is especially beneficial for ewes rearing multiple lambs when they are in relatively poor body condition and for young growing lambs with the genetic potential for fast growth.
Protein supplementation can be beneficial during times of the year when sheep consume lower-quality feed, helping them to better manage parasites. Protein supplements that have been studied include soybean meal, fish meal, cottonseed meal, urea, and dried distillers grains with solubles (DDGS). These studies have also found a reduction in fecal egg counts over a long-term period when dietary protein levels were increased.

Plant-based diets can help manage intestinal parasites
A parasite is an organism that lives in or on another and derives nourishment from the other organism, or "host". There are over 1,000 species of parasites affecting domesticated animals worldwide, and they can be classified as either external or internal. Internal parasites live in the blood or tissues inside an animal's body, and can enter an animal when it swallows contaminated food or water.
In addition to probiotics, certain herbs and plant-based foods may help support the body's defense against parasites. For example, Oregon grape, wormwood (also known as Artemisia), and black walnut have a history of use in traditional medicine for addressing parasitic infections. Spicy foods, especially those containing capsaicin, have also been suggested to have antimicrobial properties. Chili peppers, for instance, contain capsaicin, which has been shown to exert antifungal and antivirulence properties against a variety of pathogens.
Garlic has also been traditionally used for its antimicrobial properties, including against parasites. A balanced diet of whole grains, lean proteins, fruits, and vegetables, and low-fat dairy products is also recommended when treating parasites, as it can help avoid constipation, through which parasites are largely expelled from the body.
It is important to note that there is limited research on the effectiveness of natural parasite cleanses, and some of these remedies may have unintended side effects. It is always recommended to consult a healthcare professional before trying a parasite cleanse or taking any supplements, as they can help develop the best treatment plan.

Good nutrition can reduce the need for anthelmintic treatments
Good nutrition is essential in managing parasites in animals and can even reduce the need for anthelmintic treatments. Parasites are organisms that live in or on another organism, the "host", and feed on it. They can be external or internal, and almost all free-living animals are host to at least one species of parasite.
Good nutrition can help animals manage parasites in several ways. Firstly, it can improve the host's condition and immunity, thereby reducing infection. For example, research has shown that increasing metabolizable protein in the diet during protein scarcity can help sheep become more resilient to parasite infections. Additionally, certain protein supplements such as soybean meal, fish meal, and cottonseed meal have been linked to a reduction in fecal egg counts over the long term.
Secondly, good nutrition can reduce the need for anthelmintic treatments by decreasing helminth burden and increasing drug efficacy. Helminths are common parasites in humans, wildlife, and livestock, causing chronic infections. Supplemented nutrition in wood mice, for instance, resulted in stronger general and parasite-specific antibody responses, better body condition, and reduced transmission potential of the parasite H. polygyrus.
Furthermore, good nutrition can help prevent reinfection. In the case of wood mice infected with H. polygyrus, anthelmintic treatments alone resulted in reinfection within two to three weeks. However, when supplemented nutrition was applied in conjunction with anthelmintic treatment, it significantly reduced transmission potential.
Finally, good nutrition can help reduce economic losses caused by parasites. Parasites can cause economic losses by increasing rearing costs for sick animals and reducing productivity through inferior meat, milk, wool, hides, or eggs. By improving nutrition, farmers can improve animal health and productivity, thereby reducing these economic losses.
In conclusion, good nutrition can reduce the need for anthelmintic treatments by improving immunity, decreasing parasite burden, preventing reinfection, and reducing economic losses. However, further research is needed to fully understand the impact of nutrition on parasitism and to develop optimal supplementation protocols for different species.

Frequently asked questions
Diet is important for animals infected with parasites because certain foods can help to remove parasites or pathogens and avoid major infections. For example, plant-derived medicinal substances, also known as secondary plant compounds, are effective in protecting against parasites.
Bay leaves have been found to be effective in repelling fleas. In another experiment, torn bay leaves killed 75% of flea larvae. Some plant species with medicinal properties are also included in the diet of woolly spider monkeys.
Regular grooming techniques, such as licking, and consuming medicinal plant-based compounds can help prevent and treat parasites. Maintaining a balanced diet and a healthy immune system can also help get rid of parasites.
Parasites come in many forms, including helminths (worms), arthropods (lice, ticks, mosquitoes, etc.), and protozoa. Helminths are parasitic worms that live in the gastrointestinal tract and can be visible to the naked eye in their adult stage.
Parasites can infect their hosts through physical contact, the fecal-oral route, free-living infectious stages, and vectors. Trophically-transmitted parasites are transmitted by being eaten by a host and include trematodes, cestodes, and many protozoa.
