Seasonal wool production which is under some genetic performance appears to be largely responsible for variation in staple strength, fibre diameter and its confidence of variation (Butler, 1994). Baluchi sheep breed live in central and eastern parts of Iran under different altitude and weather with diverse conditions. This breed comprises 19 per cent of Iranian sheep population and its fibres known as a good quality of carpet wool. This study aimed to evaluate the seasonal effects on native wool which improving wool traits by nutritional strategy on adverse time.
