This cow calved at 2 1/2 years of age on 14 June. Her weight on 24 November (end of dry season) 320kg (700lb). She was pregnant to calf again at 3 1/2 years. Calf weighed 130kg (286lb) on 24 November.
In terms of a goal of maximum sustainable profit per ha these statistics are incredible given the fact that this was achieved on very low octane grazing during the dry season. For many man-made genotypes survival would be an achievement under such conditions.
