Popis: To insure a high consistent reproductive program in a cow herd, 90 to 95 per cent of the cows must calve early each year and wean a heavy calf. To accomplish this, the producer should follow these steps: 1. Feed heifers to reach a target weight consistent with their breed. 2. Breed heifers 45 days to a bull known to sire small calves (Longhorn or Jersey or a proven bull within a breed). Also consider cows with Brahman blood to decrease birth weight. 3. Use a 60-day breeding season in the cow herd. 4. Have cows in good to moderate body condition at calving time. 5. Have cows gaining weight three weeks before breeding and during the breeding season. 6. Remove calves for 48 hours at the start of the breeding season. 7. Breed to fertile bulls.
