1. Basics of Beef Cattle Breeding
1.1 What is Fattening?
Fattening is the process of bringing young cattle to slaughter weight in a short time with an intensive feeding program. Purpose:
- Maximum live weight gain (CAA)
- Optimum feed conversion ratio (FDO)
- Quality carcass production
- Economic profitability
1.2 Nutritional Material Selection
| material | Starting Weight | Fattening Period | Target Cutting Weight |
|---|---|---|---|
| weaning calf | 80-120kg | 12-14 months | 500-550kg |
| young tosun (native) | 200-250kg | 6-8 months | 450-500kg |
| Young tosun (culture) | 250-350kg | 4-6 months | 550-650kg |
| imported livestock | 300-400kg | 3-4 months | 550-650kg |
2. Fattening Periods and Nutrition Strategies
2.1 Adaptation Period (First 2-3 Weeks)
Purpose: Accustoming animals to the new environment and ration
- Start with roughage (70-80% roughage)
- Increase concentrated feed gradually (0.5 kg per day)
- Make sure clean water is always available
- Minimize stress factors
- Complete parasite treatment and vaccinations
2.2 Growth Period (Mid-fattening)
Purpose: Maximizing skeletal and muscular development
- Increase the concentrate rate to 50-60%
- Keep the protein rate high (14-16% HP)
- Daily CAA target: 1.0-1.3 kg
2.3 Completion Period (Last 60-90 days)
Purpose: Increasing fatness and carcass quality
- Increase the concentrate rate to 70-80%
- Increase energy density
- Reduce protein content (12-13% HP)
- Daily CAA target: 1.3-1.6 kg
3. Nutrient Requirements
3.1 Energy Requirement
| Live Weight | Daily CAA | ME (Mcal/day) | NEg (Mcal/day) |
|---|---|---|---|
| 200kg | 1.0kg | 14-16 | 3.5-4.0 |
| 300kg | 1.2kg | 20-22 | 5.0-5.5 |
| 400kg | 1.4kg | 26-28 | 6.5-7.0 |
| 500kg | 1.5kg | 32-34 | 8.0-8.5 |
3.2 Protein Requirement
| Live Weight | HP (g/day) | Ration HP (%) |
|---|---|---|
| 200kg | 700-800 | %14-15 |
| 300kg | 900-1000 | %13-14 |
| 400kg | 1000-1100 | %12-13 |
| 500kg | 1100-1200 | %11-12 |
3.3 Dry Matter Consumption
In beef cattle, KMT is generally determined by live weight. 2.2-2.8% is as much as:
| Live Weight | KMT (kg/day) | KMT (% CA) |
|---|---|---|
| 200kg | 5-6 | %2.5-3.0 |
| 300kg | 7-8 | %2.3-2.7 |
| 400kg | 9-10 | %2.2-2.5 |
| 500kg | 10-12 | %2.0-2.4 |
4. Practical Ration Formulation
4.1 Growth Period Ration (300 kg, 1.2 kg/day CAA)
| bait | Quantity (kg KM) | % Ration |
|---|---|---|
| Corn Silage | 3.0 | 40% |
| Barley Straw | 0.8 | 10% |
| Barley (crushed) | 2.0 | 27% |
| Corn (cracked) | 1.0 | 13% |
| Sunflower Meal | 0.6 | 8% |
| Mineral-Vitamin Premix | 0.1 | 2% |
| TOTAL | 7.5kg KM | 100% |
4.2 Finishing Period Ration (450 kg, 1.4 kg/day CAA)
| bait | Quantity (kg KM) | % Ration |
|---|---|---|
| Corn Silage | 2.5 | 25% |
| Barley Straw | 0.5 | 5% |
| Barley (crushed) | 3.5 | 35% |
| Corn (cracked) | 2.5 | 25% |
| Sunflower Meal | 0.8 | 8% |
| Mineral-Vitamin Premix | 0.2 | 2% |
| TOTAL | 10kg KM | 100% |
5. Feed Conversion Ratio (FCR)
5.1 What is YDO?
Feed conversion ratio is the amount of feed consumed for 1 kg of live weight gain:
5.2 Target YDO Values
| Fattening Period | Ideal YDO | Acceptable |
|---|---|---|
| adaptation | 6-7 | 7-8 |
| growth | 5-6 | 6-7 |
| finishing | 6-7 | 7-8 |
| Total Fattening | 5.5-6.5 | 6.5-7.5 |
6. Critical Management Points
6.1 Romanian Health
- Acidosis prevention: Concentration increase should be gradual
- Effective fiber: Min. 8-10% effective NDF
- Buffer substances: Add sodium bicarbonate if necessary
- Feeding frequency: Min per day. 2 times, ideal 3-4 times
6.2 Water Consumption
Beef cattle per day 8-10% of live weight Consumes as much water as:
| Live Weight | Water Consumption (L/day) |
|---|---|
| 200kg | 20-25 |
| 300kg | 30-35 |
| 400kg | 40-45 |
| 500kg | 50-55 |
6.3 Heat Stress
- Heat stress (>25°C): Feed consumption decreases, feed at night
- Cold stress (<5°C): Energy needs increase, adjust ration
7. Economic Analysis
7.1 Cost Items
| pencil | rate |
|---|---|
| Feed cost | %65-75 |
| Purchasing livestock | %15-20 |
| workmanship | %5-8 |
| veterinary/health | %2-3 |
| Other (electricity, water, etc.) | %3-5 |
7.2 Profitability Calculation (at January 2026 Prices)
Fattening intake: 300 kg × 200 TL/kg = 60,000 TL
Feed cost: 150 days × 100 TL/day = 15,000 TL
Veterinary/medicine: ~1,500 TL
Labor/shelter: ~2,000 TL
Total cost: 78,500 TL
Cutting weight: 300 + (150 × 1.3) = 495 kg
Sales (live): 495 kg × 150 TL/kg = 74.250 TL
Result: 74.250 - 78.500 = -4.250 TL (loss)
- Cheap feed source (own production silage, pasture)
- Providing low cost livestock
- High YDO (5.5-6.0)
- Direct town sales (without intermediaries)
8. Common Mistakes
| Error | Conclusion | Indeed |
|---|---|---|
| Intensive feeding without adaptation | Acidosis, death | Adapt for 2-3 weeks |
| Insufficient roughage | Romanian problems, low YDO | Min. Give 20-25% roughage |
| low quality feed | Low CAA, high YDO | Use quality feed |
| water restriction | Feed consumption decreases | Provide clean water constantly |
| overcrowded | Stress, illness, poor performance | 6-8 m² area per animal |
9. Conclusion
For a profitable livestock business:
- Choose quality breeding material - Genetic potential is important
- Pay attention to the adaptation period - Don't rush
- Adjust ration according to periods - There is no single ration
- Follow YDO - The key to profitability
- Protect Romanian health - Avoid acidosis
