Compact calving scuppered by heavy rainfall
The heavy rainfall in the month of June has surpassed all records since 1947. The implications for the dairy industry this year and next will be phenomenal.
Farmers have had to house cows by night in June and July. Grazing conditions have become very difficult on heavy ground, with grass quality and dry matter intakes severely curtailed.
Cows365 can now collect data pertaining to cows scanned and integrate this with existing farm records for calving data, AI and natural service. This enables us to analyse data for the client immediately after the farm visit.
Over the past month, we have analysed our data on six-week and eight-week pregnancy rates. Unfortunately, the figures do not make good reading.
Six-week pregnancy rates range from 30-73pc, with an average of 47pc for over 6,000 cows scanned. The eight-week pregnancy rate was 66pc, based on over 3,700 cows.
This data was collected from spring calving dairy herds with a focus on grass-based milk production.
It supports my previous contention that reproductive performance in dairy cows is unacceptably low to achieve the desired target of 85pc calving rate in a six week period.
Replacement rates of 30pc will be needed on many farms to achieve the targets centred on cost-efficient grass-based milk production.
