New Waterline Disinfection Solution: NaDCC Boosts Broiler Health & Farming Profit
The Hidden Microbial Hazards in Broiler Waterlines
Many poultry producers underestimate the microbial risks lurking within water distribution lines. Research indicates that over 95% of microorganisms in water systems adhere to pipe inner walls and form persistent biofilms, with merely 5% remaining suspended in the water flow. Driven by the warm ambient temperatures, low water velocity and nutrient-rich environment inside poultry houses, these biofilms continuously harbor harmful pathogens such as Escherichia coli, Salmonella, Staphylococcus aureus and molds.
The Destructive Contamination Cycle
Once fragments of biofilm detach, they directly contaminate drinking water. Broilers consuming contaminated water face an elevated risk of intestinal infections.
Meanwhile, excess pathogens in manure lead to excessive emissions of ammonia and hydrogen sulfide — two prevalent toxic and malodorous gases in poultry facilities. This creates a destructive cycle: compromised water quality sickens the flock, and polluted manure further worsens rearing conditions, ultimately cutting into farm revenue.
Among mainstream water treatment options, chlorine-based disinfectants are widely favored for their broad-spectrum germicidal activity, ease of application and affordability. As a well-established chlorine-releasing agent, NaDCC has long been utilized for potable water and industrial water treatment.
Efficacy of NaDCC at Varying Concentrations
A 42-day independent research project was completed by academic teams in China, simulating typical commercial broiler farming environments. The trial involved 480 newly hatched healthy AA+ broilers (average initial weight: 46.77 ± 0.50 g), divided into four groups with six repeated pens for each group.
While the control group drank regular tap water, the other three groups were provided with water containing NaDCC at 10 mg/L, 30 mg/L and 50 mg/L. A full range of indicators, including microbes, growth performance, blood parameters and harmful gas output, were recorded across the entire research period.
1. Outstanding Pathogen Control
Trial results confirmed that all three NaDCC concentrations significantly reduced the counts of E. coli, Salmonella, Staphylococcus aureus and molds within waterlines. Correlation analysis revealed a strong positive correlation between microbial levels in drinking water and broiler manure, with a correlation coefficient. This clearly demonstrates that sanitizing waterlines is critical to minimizing pathogen ingestion by broilers.
Notably, 30 mg/L and 50 mg/L NaDCC effectively lowered the abundance of harmful microbes in chicken feces, successfully curbing pathogen transmission within the flock.
2. Reduced Emissions of Harmful Gases
Ammonia and hydrogen sulfide from livestock manure impair both poultry health and the working environment for farm staff. Compared with the control group, all NaDCC-treated groups produced substantially lower levels of these two gases.
Even after prolonged manure fermentation, gas emissions stayed at a low level, substantially improving the overall air quality inside poultry barns. Therefore, using a high concentration of NaDCC for non-regular disinfection can help maintain a clean environment.
3. Enhanced Growth Performance with Proven Safety
Growth performance is the top priority for all broiler operations. Over the full 42-day trial:
Weight Gain: Broilers provided with water containing 50 mg/L NaDCC saw a statistically significant rise in average daily gain. Moderate improvements in weight gain were also observed in the 10 mg/L and 30 mg/L groups.
Feed Efficiency: From Day 22 to Day 42, NaDCC supplementation optimized the feed-to-gain ratio and boosted feed conversion efficiency.
Most importantly, NaDCC poses no adverse effects on broilers. Test data showed no notable differences in average daily feed intake or daily water consumption across all groups.
Serum antibody titers, albumin, transaminase, blood glucose and other immune and biochemical parameters also remained within normal ranges. This verifies that NaDCC does not disrupt broilers’ normal physiological functions or immune defenses.

How NaDCC Works
Its active chlorine disrupts microbial cell walls and internal components, providing quick protection against bacteria and fungi.
Its mode of action follows a clear logical chain:
NaDCC eradicates biofilms and pathogens in waterlines → reduces pathogen intake by broilers → optimizes intestinal microflora → cuts pathogen levels and toxic gas output in manure → improves overall growth performance.
As an indirect performance enhancer, NaDCC aligns perfectly with the principles of green and sustainable poultry farming.
Comprehensive Performance of Different NaDCC Concentrations
To help farm operators quickly select the optimal dosage, we summarized the core performance, advantages and applicable scenarios of each tested concentration in the table below:
| NaDCC Concentration | Microbial Control Effect | Recommended Application Scenarios |
|---|---|---|
| 0 mg/L (Control) | No inhibitory effect | Standard farming without water disinfection |
| 10 mg/L | Basic pathogen reduction | Daily basic water quality maintenance |
| 30 mg/L | Excellent pathogen inhibition | Regular use for most large-scale broiler farms (cost-effective) |
| 50 mg/L | Excellent pathogen inhibition | High-density flocks / severely polluted waterlines / maximum yield pursuit |
Conclusion
Clean drinking water serves as the first line of defense for healthy broiler production. This authoritative trial has proven that NaDCC is a safe, efficient and cost-effective waterline disinfectant for the poultry industry. It eliminates pathogens at the source, improves rearing conditions and elevates broiler production performance, with zero negative impacts on flock health.
For global poultry businesses, adding NaDCC to drinking water is a simple, scalable strategy for precision farm management. In the era of intensive livestock farming, optimizing waterline sanitation has become a reliable approach to mitigate disease risks and boost economic returns.
We will continue to share field-proven technical solutions to support the sustainable development of all our poultry partners across the globe.
