Researchers tested whether a natural supplement made from cottonseed could help chickens recover from a common intestinal infection called coccidiosis. They compared this plant-based supplement to two standard medications used in poultry farming. The study involved 420 young chickens divided into different groups. Those given the cottonseed supplement at the highest dose performed as well as or better than chickens receiving the standard medications, suggesting that natural alternatives might work just as effectively while potentially being safer for food production.

The Quick Take

  • What they studied: Whether a natural supplement made from cottonseed could help chickens recover from coccidiosis, a common intestinal disease that affects poultry farms worldwide
  • Who participated: 420 young broiler chickens (a type raised for meat) that were either healthy or deliberately exposed to the coccidiosis infection, divided into seven different treatment groups
  • Key finding: Chickens given the highest dose of cottonseed supplement (6 grams per kilogram of feed) recovered from infection just as well as chickens given standard pharmaceutical medications, with improvements in weight gain, feed efficiency, and immune response
  • What it means for you: This research suggests that natural plant-based supplements might offer farmers a viable alternative to standard medications for protecting chickens from intestinal infections, though more research in real farm conditions is needed before widespread adoption

The Research Details

Scientists conducted a controlled experiment with 420 young chickens over a 35-day period (from day 10 to day 45 of life). They divided the chickens into seven groups: one healthy control group, one group infected with coccidiosis but receiving no treatment, three groups infected but receiving different amounts of cottonseed supplement, and two groups infected but receiving standard medications (diclazuril or salinomycin). The researchers carefully measured how much the chickens ate, how much they grew, the number of parasites in their droppings, changes in their intestinal tissue, and markers of their immune system strength.

This type of study is valuable because it allows researchers to directly compare a new treatment (the cottonseed supplement) against both untreated infection and established medications under controlled conditions. By measuring multiple outcomes—growth, parasite levels, intestinal health, and immune function—the researchers could get a complete picture of how well the supplement worked.

The study used a completely randomized design, meaning chickens were randomly assigned to groups to reduce bias. This is an important scientific practice that helps ensure fair comparisons between treatments.

This research matters because coccidiosis costs the poultry industry millions of dollars annually and can cause suffering in birds. Standard medications work well but there’s growing concern about antibiotic resistance and chemical residues in food. Testing natural alternatives like cottonseed peptides could provide farmers with safer, more sustainable options that don’t contribute to antibiotic resistance problems.

This study has several strengths: it used a large number of animals (420 chickens), included proper control groups for comparison, measured multiple health outcomes, and tested different doses of the supplement. However, the study was conducted in a controlled laboratory setting rather than on actual farms, which means results might differ in real-world conditions. The researchers also didn’t report some details about how they verified the purity and consistency of the cottonseed supplement, which would strengthen confidence in the results.

What the Results Show

When chickens were infected with coccidiosis, those fed only the basic diet ate less food and grew more slowly during the middle of the study period (days 31-38). However, chickens receiving the highest dose of cottonseed supplement (6 grams per kilogram of feed) recovered their normal eating and growth patterns, performing similarly to healthy, uninfected chickens.

The infection also made it harder for chickens to convert the food they ate into body weight (a measure called feed conversion ratio). However, chickens receiving either the cottonseed supplement or standard medications improved this measure, meaning they used their food more efficiently—an important indicator of recovery.

When researchers counted parasites in the chickens’ droppings, infected chickens receiving no treatment had very high parasite levels. Chickens receiving any dose of the cottonseed supplement or either standard medication showed significantly lower parasite counts, indicating the supplement helped control the infection.

Measures of immune system strength, including antibody production, improved in chickens receiving the highest dose of cottonseed supplement, suggesting the natural supplement actually boosted immune function rather than just suppressing symptoms.

The study found that the cottonseed supplement appeared to reduce inflammation in the intestines, as indicated by lower levels of a protein called interleukin-6 that signals inflammation. The supplement also appeared to improve the structure and function of intestinal tissue, which is important for nutrient absorption and overall health. Interestingly, the middle dose (5 grams per kilogram) was less effective than the highest dose, suggesting there may be an optimal amount needed for maximum benefit.

Previous research has shown that bioactive peptides (small protein fragments) from various plant sources have antimicrobial and immune-boosting properties. This study is among the first to specifically test cottonseed peptides against coccidiosis in chickens and to directly compare them to standard medications. The results align with earlier findings suggesting natural peptides can support immune function, but this is the first direct head-to-head comparison showing they may work as well as established drugs.

The study was conducted in a controlled laboratory environment, not on actual farms, so results might differ under real-world conditions with different housing, feed quality, and stress levels. The researchers used a specific breed of chicken (Ross 308) and a specific parasite strain, so results might not apply to all chicken types or all coccidiosis variants. The study period was relatively short (35 days), so long-term effects are unknown. Additionally, the study didn’t evaluate cost-effectiveness or whether the supplement might have any negative effects with long-term use.

The Bottom Line

Based on this research, the cottonseed supplement at 6 grams per kilogram of feed appears to be a promising alternative to standard medications for protecting chickens from coccidiosis. However, this is preliminary evidence from a controlled study. Farmers should consult with veterinarians before switching from established medications, and further testing on actual farms is needed. The supplement appears safe based on this study, but long-term safety data would be valuable.

Poultry farmers and veterinarians should find this research interesting as a potential tool for managing coccidiosis. Food safety advocates and consumers concerned about antibiotic use in agriculture might appreciate the possibility of natural alternatives. However, this research is too preliminary for consumers to make personal dietary choices based on it—the study involved chickens, not humans. Pet bird owners should not attempt to use this supplement without veterinary guidance.

In this study, improvements in growth and parasite control were visible within 7-14 days of starting the supplement. However, full recovery of immune function took the entire 35-day study period. On a farm, results might take longer depending on infection severity and other environmental factors.

Want to Apply This Research?

  • For farmers using a nutrition tracking app: Log daily feed consumption per flock and weekly weight gain measurements. Track parasite counts (via fecal testing) every 7-10 days during infection periods. Compare these metrics between flocks receiving different supplements to identify which approach works best for your specific conditions.
  • Farmers could use an app to set reminders for consistent supplement dosing (6 grams per kilogram of feed), track feed batch dates to ensure freshness, and log any health observations in individual birds. The app could alert farmers when parasite counts should be rechecked and help compare costs between the supplement and standard medications.
  • Establish a baseline of normal performance metrics for your flock (feed intake, growth rate, parasite levels). If coccidiosis appears, begin supplementation and track the same metrics weekly. Compare recovery speed and final performance to your baseline and to previous outbreaks treated with standard medications. Document any unexpected effects. Share data with your veterinarian to build evidence for your specific farm conditions.
