The effect of lactation anoestrous of first-calf cows on calf weaning weight

In Australian beef production, lactation anoestrous, the period after calving when a cow is lactating and doesn't experience an oestrous cycle, is a critical factor influencing profitability, particularly in first-calf cows. This paper aimed to determine whether first-calf cows that returned to oestrus by weaning had lighter calves.
