How is submission be monitored?
Submission rate
* No of animals served, eligible, 3 week cycle
1st service submission rate
* All animals after earliest service date who have not been served
All services submission rate
* All animals after earliest service date who are not pregnant
If not served- disease or failure to observe
Did it get served?- every 3 weeks all eligble should be served
- What is conception rate?
- Should PD be early or later?
- % pregnant of those served
- PD later- more predictive of calving, PD early- detect empty ealier
How can conception, submission be analysed?
- Cull rate for fertility
- % recalving
- Which type of animal is worst affected- risk
What is the problem with calving interval?
Needs to have calved twice- doesnt show fertility of heifers
What is the purpose of the voluntary waiting period?
If conceived to early then will have to by dryed off at peak lactation- less milk
If too late- more lifetime in late lactation
What is the purpose of interservice intervals?
Shows heat detection
Intervals- should be 3 weeks
What is the difference between pregnancy rate and conception rate?
Conception- if served what % pregnant
Preg rate- no of pregs/no of eligble cows (3 weeks) x100
So conception X submission
