False Statement About Tibial Dyschondroplasia
Which of the following statements about Tibial Dyschondroplasia is NOT true?
- It is a leg disorder in broilers
- It is a leg disorder in layers — Correct Answer
- Abnormal formation of cartilage in leg bones is involved
- High dietary level of chloride may increase incidence
Explanation:
Correct Answer (NOT TRUE): It is a leg disorder in layers
Tibial Dyschondroplasia (TD) is a leg disorder in BROILERS, NOT layers. It occurs due to abnormal cartilage formation in the proximal tibia (tibiotarsus), leading to lame birds and economic losses in broiler production.
Tibial Dyschondroplasia — Key Facts
- Affects: Primarily fast-growing broilers (not layers).
- Lesion: Abnormal, non-vascularised plug of cartilage in the growth plate of the tibia.
- Predisposing factors: Rapid growth, high dietary chloride, dietary cation-anion imbalance, deficiencies of Vit. D, Ca, or P.
- Clinical signs: Leg weakness, lameness, swollen hock joints.
Leg Problems in Poultry — Summary
| Condition | Species Affected | Cause |
|---|---|---|
| Tibial Dyschondroplasia | Broilers | Abnormal cartilage; high Cl diet |
| Perosis (Slipped tendon) | Both | Mn, Biotin, Choline, Folic acid deficiency |
| Cage Layer Fatigue | Layers | Ca, P, Vit. D deficiency + no exercise |
| Swollen hock syndrome | Both | Zinc deficiency |
