Many district herds are in the “calving to mating” period of the season. The bulk of the herd is calving and joining is fast approaching for many seasonal and split calving herds.
An essential step to take is to plan a strategy around the mating start date (MSD) on your farm to address each of the issues. Groups of cows can be selected for appropriate treatment delivered at a time to provide maximum benefit reproductively.
Management decisions made in the “calving to mating” period can have large effects on your herd’s reproductive performance. Critical points right now on many farms are;
- Pre-joining live weight of maiden heifers
- Body Condition of the milking herd
- Individual cow health (lameness) & reproductive conditions
- Considering a pre-mating heat detection program
- Planning programs for cycling (synchronisation) & non-cycling (anoestrus) cows early so that time is not lost & treatments wasted early in the joining season
- Review Heat Detection & AI programs to be used including facilities required
4 keys for good reproductive performance
- Attend to ‘at risk’ cows prior to the start of mating. Organise post natal checks and treatments if necessary.
- Consider using synchronisation in the milking herd and heifers to increase your 30 day submission rate to A.I.
- Submit non-cycling cows for examination & treatment as early as possible in the joining season. NVOs identified and treated 7-10 days before MSD will be joined at the same time as their cycling herd mates.
- Do not forget about clean up bulls. Your ‘clean-up’ bull team should be organised (adequate numbers), pestiviris checked and vibrio vaccinated 3-4 weeks prior to use.
