Optimizing FCR in Commercial Poultry Farming: Integrating Ethnoveterinary Knowledge & Indigenous Practices for Sustainable Growth in India

In commercial poultry production, Feed Conversion Ratio (FCR) is a crucial performance indicator that determines the efficiency of feed utilization by birds to produce meat or eggs. Since feed costs account for 65-75% of total production expenses, optimizing FCR is essential for ensuring profitability and sustainability in poultry farming.

2. What is Feed Conversion Ratio (FCR)?

Feed Conversion Ratio (FCR) is the measure of how efficiently poultry converts feed into body weight (for broilers) or eggs (for layers). It is expressed as:

FCR=Total Feed Consumed (kg)Total Body Weight Gain (kg) or Egg Mass (kg)FCR = \frac{\text{Total Feed Consumed (kg)}}{\text{Total Body Weight Gain (kg) or Egg Mass (kg)}}FCR=Total Body Weight Gain (kg) or Egg Mass (kg)Total Feed Consumed (kg)​

FCR Standards in Poultry Farming

• Broilers: An ideal FCR is 1.5 – 1.8, meaning 1.5 to 1.8 kg of feed is required to produce 1 kg of live weight.
• Layers: FCR for layers is measured in terms of feed consumed per dozen eggs or per kg of egg mass. The typical range is 1.9 – 2.2.
• Breeders: The FCR varies depending on age, breed, and management, generally ranging from 2.0 – 2.5.

3. Importance of FCR in Commercial Poultry Farming

(A) Economic Profitability

1. Lower FCR Means Higher Profitability

1. • A lower FCR indicates that birds require less feed to gain weight or produce eggs, reducing the overall feed cost.
   • Even a 0.1 improvement in FCR can lead to significant savings for large-scale farms.

2. Impact on Feed Cost Management

1. • Since feed accounts for 70% of total production costs, improving FCR helps in reducing feed wastage and optimizing resource utilization.

(B) Growth Performance and Productivity

1. Better Growth Rate in Broilers
   • Efficient feed conversion ensures faster weight gain, leading to shorter rearing cycles and more production cycles per year.
2. Higher Egg Production in Layers
   • In layers, an improved FCR means more eggs produced with less feed consumption, directly impacting farm profitability.

(C) Environmental Sustainability

1. Reduced Feed Waste & Resource Utilization
   • Efficient FCR means less feed consumption per bird, leading to lower feed production requirements and reduced environmental impact.
2. Lower Carbon Footprint
   • Since feed production involves land, water, and energy resources, improved FCR reduces GHG emissions associated with poultry farming.

4. Factors Affecting FCR in Poultry Production

(A) Nutrition & Feed Quality

1. Balanced Feed Formulation

1. • Poultry diets must be well-balanced in energy, protein, amino acids, vitamins, and minerals to ensure optimal growth and feed efficiency.

2. Feed Particle Size & Digestibility

1. • Fine-grinding of feed improves digestibility but may lead to feed wastage, whereas pelleted feed enhances FCR by reducing selective feeding.

3. Quality of Protein & Energy Sources

1. • High-quality protein sources (soya meal, fish meal) and energy sources (corn, wheat) improve nutrient absorption, leading to a better FCR.

(B) Bird Management & Health

1. Breed Selection & Genetics

1. • Modern commercial broiler breeds like Cobb 500, Ross 308 are genetically selected for low FCR and high feed efficiency.

2. Health & Disease Control

1. • Gut health disorders, coccidiosis, and respiratory diseases negatively impact digestion and nutrient absorption, leading to poor FCR.
   • Probiotics, prebiotics, and organic acids improve gut health, ensuring efficient feed utilization.

3. Stress Management

1. • Heat stress, overcrowding, and improper ventilation reduce feed intake and increase maintenance energy needs, leading to a higher FCR.

(C) Housing & Farm Management

1. Temperature & Ventilation Control

1. • Birds require an optimal temperature range (22-28°C) for efficient feed conversion.
   • Heat stress leads to reduced feed intake, affecting FCR.

2. Stocking Density

1. • Overcrowding causes stress, competition for feed, and poor growth performance, leading to a higher FCR.

3. Feeding Techniques

1. • Ad libitum feeding (free access to feed) ensures birds consume adequate nutrients for better weight gain and egg production.

5. Strategies to Improve FCR in Poultry Farming

(A) Nutritional Strategies

1. Precision Feed Formulation

1. • Use of digestible amino acids (lysine, methionine, threonine) to enhance protein efficiency.
   • Optimized energy-to-protein ratio for different growth phases.

2. Use of Feed Enzymes

1. • Phytase, protease, and xylanase improve nutrient digestibility and reduce feed wastage.

3. Incorporation of Functional Additives

1. • Probiotics, prebiotics, organic acids, and essential oils enhance gut health and nutrient absorption.

(B) Farm Management Strategies

1. Optimal Stocking Density

1. • Maintain proper bird density (Broilers: 6-8 birds/sq. ft.; Layers: 2-3 birds/cage) to minimize stress and competition.

2. Controlled Environment Housing (CEH)

1. • Regulating temperature, humidity, and airflow reduces heat stress and improves feed efficiency.

3. Biosecurity Measures

1. • Strict disease control and vaccination programs prevent disease outbreaks that negatively impact FCR.

6. Role of FCR in Future Poultry Industry Growth

• Improving FCR aligns with the Indian poultry sector’s goal of sustainability and profitability.
• With increasing feed ingredient costs and environmental concerns, maintaining a low FCR will be key to long-term success.
• Adoption of precision feeding, genetic selection, and technology-driven farm management will enhance productivity and reduce production costs.

Role of Ethnoveterinary Knowledge (EVK) & ITK in Reducing FCR

Ethnoveterinary Knowledge (EVK) and Indigenous Technical Knowledge (ITK) involve traditional herbal and natural remedies used by Indian farmers for centuries to improve poultry health and productivity. These methods reduce disease incidence, enhance gut health, and improve digestion, leading to better FCR.
