Research shows that adding 5% dried cactus powder to rabbit feed improved fiber digestion by 23%, reduced harmful blood cholesterol and fats, and increased beneficial gut bacteria without affecting growth or meat quality. According to Gram Research analysis of this 2026 study, the cactus powder triggered structural improvements in the small intestine, suggesting it acts as a functional ingredient that supports digestive and metabolic health in growing animals.
Researchers tested whether dried cactus plant powder could improve the health of growing rabbits. According to Gram Research analysis, adding 5% cactus powder to rabbit feed improved how well the animals digested fiber by about 23%, reduced harmful cholesterol and fats in their blood, and changed their gut bacteria in beneficial ways. The rabbits grew normally and stayed healthy, suggesting this cactus powder could be a useful natural ingredient in animal feed. The findings show that plant-based ingredients can support digestive and metabolic health without affecting growth or meat quality.
Key Statistics
A 2026 study of 70 rabbits found that 5% dried cactus powder increased crude fiber digestibility by approximately 23% compared to control feed, indicating improved digestive efficiency.
Research published in Frontiers in Veterinary Science showed that cactus powder reduced total cholesterol and triglycerides in rabbit blood while decreasing harmful malondialdehyde levels, suggesting protective effects on cellular health.
In a 6-week feeding trial with 70 rabbits, dried cactus powder reduced harmful E. coli bacteria while increasing beneficial Lactobacillus species in the digestive system without affecting overall bacterial counts.
A 2026 animal study demonstrated that rabbits fed 5% cactus powder showed increased intestinal villus height and crypt depth, indicating intestinal remodeling and improved nutrient absorption capacity.
The Quick Take
- What they studied: Whether adding dried cactus plant powder to rabbit feed would improve digestion, reduce harmful blood fats, and support gut health without slowing growth.
- Who participated: Seventy male Italian White rabbits, divided into two equal groups of 35. The rabbits were 42 days old at the start and fed their assigned diets for 6 weeks until they reached 84 days old.
- Key finding: Rabbits eating 5% cactus powder digested fiber 23% better than control rabbits, had lower cholesterol and triglycerides, and showed beneficial changes in gut bacteria, all while maintaining normal growth and meat quality.
- What it means for you: This research suggests cactus powder could be a natural, plant-based ingredient to support digestive health in animals. While this study focused on rabbits, it opens possibilities for similar benefits in other animals and potentially humans, though more research is needed.
The Research Details
Scientists divided 70 young rabbits into two groups at 42 days of age. One group ate normal feed (the control group), while the other group ate the same feed with 5% dried cactus plant powder added. Both groups were fed this way for 6 weeks until the rabbits were 84 days old. The researchers then measured how well each group digested their food, checked their blood for cholesterol and fats, examined their gut bacteria, and looked at the structure of their intestines under a microscope.
This type of study is called a controlled experiment because it compares two similar groups that differ in only one way: the addition of cactus powder. This design helps researchers figure out whether the cactus powder itself caused any changes they observed, rather than other factors.
The researchers measured many different health markers, including how much fiber the rabbits could digest, levels of protective molecules called antioxidants in their blood, the types of bacteria living in their digestive system, and the structure of their intestinal lining. They also tracked whether the rabbits grew normally and produced good quality meat.
This research approach matters because it tests whether a natural plant ingredient can improve animal health without causing problems. By measuring so many different health markers, the researchers could see exactly how the cactus powder affected the rabbits’ bodies. This comprehensive approach helps scientists understand whether natural ingredients are truly beneficial or just seem helpful on the surface.
This study has several strengths: it used a reasonable number of animals (70 total), randomly assigned them to groups to reduce bias, and measured many different health outcomes. The study was published in a peer-reviewed scientific journal, meaning other experts reviewed it before publication. However, the study only lasted 6 weeks and only tested rabbits, so we cannot yet know if these benefits would last longer or apply to other animals or humans. The researchers were transparent about their methods, which allows other scientists to repeat or build on their work.
What the Results Show
The most important finding was that rabbits eating cactus powder digested fiber much better than rabbits eating normal feed. Specifically, their crude fiber digestibility improved by about 23%, and their neutral detergent fiber digestibility improved by about 18%. This means their digestive systems were more efficient at breaking down and absorbing plant fiber.
The cactus powder also improved the rabbits’ blood chemistry. Levels of malondialdehyde, a harmful molecule that damages cells, decreased significantly. Total cholesterol and triglycerides, both types of fats in the blood that can affect heart health, also decreased. These changes suggest the cactus powder has protective effects on the body’s cells and may support heart health.
Interestingly, despite these improvements in digestion and blood chemistry, the rabbits eating cactus powder grew just as well as the control rabbits. They gained weight at the same rate, converted their feed into body weight equally efficiently, and produced meat of the same quality. This is important because it shows the cactus powder provided health benefits without any negative effects on growth or productivity.
The cactus powder also changed the types of bacteria living in the rabbits’ digestive systems. Harmful bacteria called E. coli decreased, while beneficial bacteria called Lactobacillus increased. These changes suggest the cactus powder supports a healthier gut environment.
The researchers also examined the structure of the rabbits’ small intestines under a microscope. They found that rabbits eating cactus powder had taller finger-like projections called villi and deeper pockets called crypts in their intestinal lining. These structural changes suggest the intestines were remodeling and becoming more efficient at absorbing nutrients. The researchers did not find changes in other measures like intestinal pH, ammonia levels, or total bacterial counts, suggesting the cactus powder’s effects were selective rather than causing broad changes throughout the digestive system.
Previous research has shown that Opuntia cactus plants contain fiber and bioactive compounds with potential health benefits. This study adds to that knowledge by showing that moderate amounts of dried cactus powder, specifically 5% of the diet, can deliver real health improvements in growing animals. The findings align with earlier research suggesting cactus can support digestion and reduce harmful blood fats, but this study provides more detailed evidence about how these benefits occur at the cellular and bacterial levels.
This study has several important limitations. First, it only lasted 6 weeks, so we do not know if the benefits would continue over a longer period or if the rabbits’ bodies might adapt over time. Second, the study only tested one dose of cactus powder (5%), so we do not know if higher or lower doses might work better. Third, this research was conducted only in rabbits, so we cannot assume the same benefits would occur in humans or other animals without additional studies. Fourth, the study did not measure some factors that might be important, such as how the cactus powder affected the rabbits’ immune system function. Finally, the study did not track the rabbits after the feeding period ended, so we do not know if any benefits persisted.
The Bottom Line
Based on this research, dried cactus powder appears to be a safe and effective ingredient for animal feed at 5% inclusion levels. It can improve fiber digestion, reduce harmful blood fats, and support beneficial gut bacteria without affecting growth or meat quality. However, these findings are from a single 6-week study in rabbits, so confidence in applying these results to other species or longer time periods is moderate. More research is needed to determine optimal doses and long-term effects.
This research is most relevant to animal feed manufacturers and farmers raising rabbits or similar animals. Veterinarians interested in natural feed additives may find this useful. While the study focused on animals, the results suggest cactus powder might have similar benefits for humans, but direct human studies would be needed to confirm this. People interested in natural, plant-based ingredients for supporting digestive and heart health should note this as a promising area for future research.
In this study, the benefits of cactus powder appeared within 6 weeks of feeding. However, we do not know if benefits would continue to increase with longer feeding, plateau, or eventually decrease. Realistic expectations based on this research are that improvements in fiber digestion and blood fat levels could appear within several weeks, but individual results may vary.
