Cumulative FCR (Live Weight Basis — Breeder Standard)

Cumulative Feed Intake (g) / Final Live Body Weight (g)
Computation: 5049g / 3060g
= 1.65
STEP 02Verified

Net Live Weight Gain Computation

Final Weight - Initial Day 0 Chick Placement Weight
Computation: 3060g - 42g
= 3018 g
STEP 03Verified

Average Daily Gain (ADG)

Net Weight Gain / Elapsed Production Days
Computation: 3018g / 42 days
= 71.86 g/day

Cumulative Feed Conversion Ratio (Live Weight Basis)

VERIFIED
cumulativeFeedGrams / finalWeightGrams

Total cumulative feed consumed divided by final live body weight. Authoritative standard utilized in commercial broiler production and published breeder management guidelines (Cobb-Vantress, Aviagen, VenCobb).

Source: Cobb 500 Broiler Performance & Nutrition Supplement (2022 Edition) (src_cobb500_manual_2022)
Assumptions: Calculates unadjusted cumulative feed intake divided by final live body weight. Does not subtract initial chick placement weight. This is the exact metric used in published commercial breed performance tables.
Units: feed kg / live weight kg (ratio)

Feed-to-Gain Ratio (Weight Gain Basis)

VERIFIED
cumulativeFeedGrams / (finalWeightGrams - initialWeightGrams)

Total cumulative feed consumed divided by net body weight gained, subtracting Day 0 chick placement weight. Recognized scientific convention in controlled poultry nutrition and academic metabolic trials.

Source: Poultry Science Academic Research Trial Convention (src_poultry_science_convention)
Assumptions: Strictly subtracts initial chick weight (typically 40-42g) from final slaughter weight. Yields a numerically higher ratio than live-weight FCR. Not directly comparable to published commercial breed benchmark curves.
Units: feed kg / gained kg (ratio)

Average Daily Gain (ADG)

VERIFIED
(finalWeightGrams - initialWeightGrams) / ageDays

Average daily net live weight gain per bird over the production cycle.

Source: Cobb 500 Broiler Performance & Nutrition Supplement (2022 Edition) (src_cobb500_manual_2022)
Assumptions: Assumes linear average across total elapsed calendar days from placement to evaluation age.
Units: grams / day

European Production Efficiency Factor (EPEF)

VERIFIED
(livabilityPercent * (finalWeightGrams / 1000)) / (ageDays * fcrLiveWeight) * 100

Standard composite efficiency index combining flock livability, live slaughter weight, age, and live-weight FCR.

Source: Aviagen Ross 308 Broiler Performance Objectives (2022 Edition) (src_ross308_objectives_2022)
Assumptions: Standard international formula (European Poultry Federation). Strictly requires FCR evaluated on a Live Weight Basis in the denominator. Livability is expressed as a whole percentage (e.g. 96.5).
Units: index points
फार्मिंग के मुख्य उपाय: वजन और FCR का अंतर सुधारें

सही वैज्ञानिक ज्ञान से अपने फ्लॉक का प्रदर्शन और मुनाफा बढ़ाएं

सिमुलेशन दिखाता है कि आपका फ्लॉक मानक से कितना पीछे या आगे है। FCR सुधारने और तेजी से वजन बढ़ाने के दो सबसे बड़े उपाय हैं: सही दाना (Feed) और शेड का सही तापमान/वेंटिलेशन।

दाना व पोषण मानक

ब्रायलर पोषण और चरण-वार दाने (Feed) के मानक

उत्कृष्ट वजन के लिए प्री-स्टार्टर, स्टार्टर और फिनिशर दाने में आवश्यक प्रोटीन (CP), ऊर्जा (ME) और जरूरी पोषक तत्व देखें।

शेड तापमान और वेंटिलेशन (हवा की गति) प्रबंधन

गर्मियों में चूजों का दाना खाना बनाए रखने के लिए सही स्टैटिक प्रेशर, टनल हवा की गति और ठंडक की जांच करें।
