6 Recommendations for 1st calf cows
|
1. match time of calving with average onset of season (due to improved nutrition of dams)
2. determine best calving time for each farm 3. Separate first calvers from adults and ensure supplementary feed quality of these younger cows 4. Monitor condition score and weights (no less than 2 BCS and 320kg LW) 5. Use strategic parasite control over summer +/- autumn (more susceptible than adult cows) 6. ID cows and calves to each other by ear tags (determine who is rearing the best calves) |
