Lamb and kid fattening is a profitable animal husbandry activity that is in high demand in Türkiye, especially before Eid-al-Adha and during the winter months. A successful fattening program is possible with correct animal selection, optimum ration formulation and effective management. Research shows that in well-managed fattening programs, daily live weight gain (GCAA) can be kept at 250-350 g/day and feed conversion ratio (FDO) can be kept at 4-5 kg feed/kg live weight gain (Karim et al., 2007). In this guide, we will discuss the basics of lamb and kid fattening, ration recommendations and economic analysis in detail.
1. Nutrition Material Selection

7.3 Urinary Stone (Urolithiasis) Prevention
Intensive grain feeding increases the risk of urinary stones in male lambs:
- Ca:P ratio: Minimum 2:1, ideal 2.5:1
- Ammonium chloride: Add 0.5-1% to the diet (urine acidifier)
- Salt: 0.5-1% (increases water consumption)
- Water: Clean, fresh, free access
- Magnesium: Avoid extreme

- Do not skip the adaptation period (1-2 weeks)
- Increase feed gradually, avoid acidosis
- Apply ration appropriate to periods (growing → finishing)
- Keep at least 15-20% roughage
- Clostridial vaccine and parasite control are a must
- Lowering YDO increases profitability
- Plan 90-100 days in advance for Eid al-Adha
Work with your veterinarian and animal nutritionist to optimize your fattening program.
