CARIBRO-Vishal
CARIBRO-Vishal (also known as CARI Vishal or Vishal Broiler) is a commercial white-plumaged broiler genotype developed by ICAR-Central Avian Research Institute (CARI), Izatnagar, in the 1990s. It was developed to deliver balanced, cost-effective performance under Indian environmental and management conditions. It topped the 30th Random Sample Poultry Performance Test (RSPPT), demonstrating its genetic potential and adaptability.
Practical Overview & Field Action
Field Verification Checkpoints
- FCR Benchmarks: ≤1.80 at 7 weeks (technical specifications); 1.85–2.05 at 6 weeks (research trial averages)
Breed Characteristics
Economic Importance
CARIBRO-Vishal is primarily utilized by small-to-medium-scale farmers in Northern and Central India who require a robust broiler that performs reliably on standard or alternative feed formulations. Research has shown that dietary supplementation with probiotics like Lactobacillus reuteri can significantly enhance immune response, gut health, and growth performance.

It was designed to deliver balanced, cost-effective performance under Indian environmental and management conditions. The latest genetic version is CARIBRO-Vishal (White Plumage).
Origin
Developed by ICAR-CARI, Izatnagar. Alternate names include CARI Vishal and Vishal Broiler. It topped the 30th Random Sample Poultry Performance Test (RSPPT), demonstrating its genetic potential under standard evaluation conditions.
Production Performance
| Performance Parameter | Technical Specifications | Research Trial Averages |
|---|---|---|
| Market Age | 6–7 weeks | 6 weeks |
| Weight at 5 Weeks | 1.500–1.600 kg | 1.350–1.480 kg |
| Weight at 6/7 Weeks | 2.100 kg (at 7 weeks) | 1.750–1.950 kg (at 6 weeks) |
| FCR (Grow-out) | ≤1.80 (at 7 weeks) | 1.85–2.05 (at 6 weeks) |
| Livability Percentage | ≥97.0% | 95.0%–97.5% |
| Dressing Yield | 70.0%–72.0% | 68.5%–70.8% |
Key Characteristics
- Feather Color: White
- Growth Rate: Balanced — uniform growth and carcass quality under standard conditions
- Uniformity: High — selected for uniform growth and carcass quality
- Heat Tolerance: High — excellent disease resistance and climate adaptability
- Leg Strength: Good — robust metabolic profile
Management Requirements
- Housing: Traditional open-sided and semi-controlled housing systems
- Brooding Temperature: 33°C on day one, reducing weekly
- Stocking Density: 1.15–1.25 sq. ft. per bird
- Lighting: 18–20 hours of light
- Feed Program: Standard maize-soya based diets; can incorporate alternative raw materials like rice gluten meal (up to 15%) without significant performance declines; dietary supplementation with probiotics like Lactobacillus reuteri significantly enhances immune response, gut health, and growth performance
Health Considerations
- Excellent disease resistance and climate adaptability under variable field conditions
- Good leg strength with robust metabolic profile
- Research has shown that dietary supplementation with probiotics like Lactobacillus reuteri can significantly enhance immune response, gut health, and growth performance
Economic Importance
Valued for its balanced, cost-effective performance. Reliability and ability to utilize lower-cost feed formulations make it profitable, particularly for small-scale and independent operations. Topped the 30th Random Sample Poultry Performance Test (RSPPT).
Advantages
- Balanced, cost-effective broiler performance
- Good adaptability to varied housing and management systems
- Strong performance and digestive health on alternative feed formulations
- Developed specifically for Indian climate and disease conditions
Limitations
- Slower growth rate and higher FCR compared to specialized commercial broilers in intensive systems
- Less established distribution network compared to private commercial brands like Vencobb
Best Suitable Farming Systems
- Traditional open-sided and semi-controlled housing systems
- Small-to-medium-scale farmers in Northern and Central India
- Farms requiring performance on alternative feed formulations

Anak
The Israeli Anak broiler line was a commercial broiler genotype developed by Anak Breeders in Israel and introduced to India in the late 1970s and 1980s. It offered good heat tolerance due to its genetic development in Mediterranean climates. However, its lack of local technical and breeding infrastructure prevented it from competing effectively with dominant localized Cobb lines, leading to its discontinuation. It is no longer commercially available.
Arbor Acres Plus
The Arbor Acres Plus is a commercial broiler genotype developed by Aviagen Group in the United States, first introduced in the 1990s and available in India since the late 1990s to early 2000s. It was bred to deliver balanced, cost-effective performance across a range of housing systems and environmental conditions. The latest genetic version is the Arbor Acres Plus (2012/2019 Performance Objectives).
CARIBRO-Dhanraja
CARIBRO-Dhanraja (also known as CARI Dhanraja or Dhanraja Coloured Broiler) is a multi-colored commercial broiler genotype developed by ICAR-Central Avian Research Institute (CARI), Izatnagar, in the 1990s. It was developed to support backyard and semi-intensive poultry farming in India. It is primarily utilized by small-to-medium-scale farmers who require a colored broiler that fetches a premium in local live-bird markets.
CARIBRO-Mritunjaya
CARIBRO-Mritunjaya (also known as CARI Mritunjai or Mritunjaya Broiler) is a commercial broiler genotype developed by ICAR-Central Avian Research Institute (CARI), Izatnagar, in the late 1990s to early 2000s. It incorporates the Naked Neck gene, which reduces feather coverage on the neck and body by approximately 20%–30%, improving the bird's ability to dissipate heat and survive in high temperatures. It was developed specifically for hot and dry agro-climatic zones of India.
CARIBRO-Tropicana
CARIBRO-Tropicana (also known as CARI Tropicana or Tropicana Broiler) is a commercial broiler genotype developed by ICAR-Central Avian Research Institute (CARI), Izatnagar, in the late 1990s to early 2000s. It incorporates both the Naked Neck and Frizzle genes, which significantly reduce feather coverage and modify feather structure to improve heat dissipation and survival in high temperature and humidity. It was developed specifically for hot and humid coastal and tropical regions of India.
