Nicarbazin NBZ Rapid Test Kit for Chicken Feed Samples – 10 Tests/Kit

Nicarbazin NBZ Rapid Test Kit for Chicken Feed Samples – 10 Tests/Kit

Introduction

The Nicarbazin NBZ Rapid Test kit for chicken feed samples – 10 tests/kit is an essential diagnostic tool used in veterinary food safety and poultry production. Designed for the rapid detection of nicarbazin residues, this kit enables feed manufacturers, laboratories, and regulatory bodies to ensure compliance with international safety standards.

Nicarbazin is widely used in poultry farming as a coccidiostat, making residue monitoring critical to prevent contamination of the food chain and ensure consumer safety.

What is Nicarbazin?

Nicarbazin is a broad-spectrum anticoccidial drug commonly added to poultry feed to prevent infections caused by Eimeria species. It is a complex of two components:

  • DNC (4,4′-dinitrocarbanilide) – the biologically active residue marker
  • HDP (2-hydroxy-4,6-dimethylpyrimidine)

After administration, these components follow different metabolic pathways, with DNC persisting longer and being the primary target for residue detection.

Due to its widespread use, regulatory agencies impose strict maximum residue limits (MRLs) in feed, meat, and eggs to avoid toxicity and contamination risks.

Principle of the NBZ Rapid Test Kit

The Nicarbazin NBZ Rapid Test kit for chicken feed samples is based on lateral flow immunochromatographic assay (LFIA) technology.

Key Mechanism:

  • Uses specific antibodies targeting DNC residues
  • Sample extract migrates along a test strip
  • Competitive binding occurs between free nicarbazin and immobilized antigens
  • Visual results are interpreted as positive or negative lines

This immunoassay approach allows rapid screening without the need for complex instrumentation like HPLC or LC-MS.

Key Features and Specifications

The kit is designed for efficiency, accuracy, and field usability:

  • Sample type: Chicken feed
  • Format: 10 tests per kit
  • Detection method: Immunochromatographic assay
  • Time to result: Approximately 10–15 minutes
  • Application: On-site or laboratory screening
  • Ease of use: Minimal training required
  • Sensitivity & specificity: Optimized for residue detection in feed

Each kit includes all reagents required to perform 10 independent tests, making it suitable for routine quality control.

Workflow of the Test Procedure

Step-by-step process:

  1. Sample Preparation
    • Grind and homogenize feed sample
    • Extract using appropriate solvent buffer
  2. Sample Application
    • Add extract to the test device
  3. Reaction Phase
    • Capillary migration occurs along the strip
    • Antigen-antibody interaction develops
  4. Result Interpretation
    • Two lines: Negative (no detectable residue)
    • One line: Positive (presence of nicarbazin residue)

Conclusion

The Nicarbazin NBZ Rapid Test kit for chicken feed samples – 10 tests/kit is a powerful tool for rapid, on-site detection of veterinary drug residues in poultry feed. By combining speed, simplicity, and reliability, it plays a crucial role in modern food safety systems.

For poultry producers and laboratories, integrating rapid testing into routine workflows ensures:

  • Regulatory compliance
  • Safer food products
  • Improved quality control
