FIRST TERM | WEEK 9: LIVESTOCK RECORD ANALYSIS

---

1. Profit and Loss Determination

Livestock Record Analysis is the mathematical process of evaluating raw farm records to determine economic viability, financial standing, and biological production efficiency of a livestock enterprise.

Key Financial Terminology:

• Total Revenue (TR): The total money earned from selling farm products (meat, eggs, live animals, manure, hides) over a given period.
  TR = Total Quantity Sold × Price per Unit
• Total Cost (TC): The sum of all operational expenses incurred to produce the farm output.
  TC = Variable Costs (VC) + Fixed Costs (FC)
  • Variable Costs (VC): Expenses that change directly with production volume (e.g., feed, vaccines, day-old chicks, day labor, fuel).
  • Fixed Costs (FC): Expenses that remain constant regardless of production level (e.g., equipment depreciation, land rent, permanent staff salaries).
• Net Profit or Loss: The difference between Total Revenue and Total Cost.
  Net Profit/Loss = Total Revenue (TR) − Total Cost (TC)
  • If TR > TC → Profit (Positive financial balance)
  • If TR < TC → Loss (Negative financial balance)
  • If TR = TC → Break-even Point (Zero profit or loss)

2. Evaluating Production Efficiency Parameters

Biological performance records indicate how efficiently animals convert input resources (like feed) into output products (meat or eggs).

Efficiency Metric	Mathematical Formula	Interpretation Benchmark
Feed Conversion Ratio (FCR)	FCR = Total Feed Consumed (kg) / Total Weight Gain (kg)	Lower values indicate high feed efficiency (e.g., Broiler FCR of 1.6–1.8 is excellent).
Mortality Rate (%)	Mortality % = (Number of Dead Birds / Initial Number Stocked) × 100	Standard commercial target: <5% in broilers; <8% in laying flocks per year.
Hen-Day Production (% HDP)	% HDP = (Total Eggs Collected Today / Number of Birds Present) × 100	Peak laying target: 85%–95%. Culling is triggered when flock falls below 50–55%.

3. Practical Worked Calculation Example

Scenario Problem:
A farmer stocked 500 broiler chicks at ₦500 each. Over 7 weeks, the flock consumed 70 bags of feed at ₦15,000 per bag. Medication, electricity, and labor totaled ₦200,000. At the end of 7 weeks, 480 surviving broilers (average weight 2.5 kg) were sold at ₦6,000 each.

Calculations:

1. Total Revenue (TR): 480 broilers × ₦6,000 = ₦2,880,000
2. Variable Costs:
   • Chicks cost: 500 × ₦500 = ₦250,000
   • Feed cost: 70 × ₦15,000 = ₦1,050,000
   • Medication/Labor/Utilities = ₦200,000
   Total Cost (TC) = ₦250,000 + ₦1,050,000 + ₦200,000 = ₦1,500,000
3. Net Profit: ₦2,880,000 (TR) − ₦1,500,000 (TC) = ₦1,380,000 Profit
4. Mortality Rate: [(500 − 480) / 500] × 100 = (20 / 500) × 100 = 4% Mortality (Excellent control).

CLASS EVALUATION & REVISION QUESTIONS

1. Distinguish between Variable Costs and Fixed Costs on a livestock farm, giving two examples of each.
2. State the formula for calculating Net Profit or Loss.
3. What does a Feed Conversion Ratio of 1.8 mean in broiler chicken production?
4. Calculate the Hen-Day Production percentage for a layer house containing 800 hens that produced 680 eggs in a single day.

HOME ASSIGNMENT:
A pig farmer stocked 20 weaners at ₦15,000 each. Feeding costs amounted to ₦450,000, while veterinary treatments cost ₦50,000. If 2 pigs died and the remaining 18 pigs were sold at market weight for ₦65,000 each, calculate: (a) Total Revenue, (b) Total Cost, (c) Net Profit or Loss, and (d) Percentage Mortality Rate.
