LIC reports 18% increase in beef straws used in dairy cows this spring
The number of beef straws going into dairy cows is on the increase, according to LIC beef genetics product lead Paul Charteris.
Non-cyclers reduce herd reproductive performance and farm profitability by dragging down submission and conception rates and achieving fewer days in milk in the following year than their cycling herd mates.
In most herds, the types of cows that become non-cyclers tend to be the same from year to year.
Non-cycling in cows show up as follows:
- young, first and second calvers, especially if poorly grown
- thin cows
- late calvers
- health issues
- breed (Friesians are more susceptible)
For cows cycled but not detected, plan to improve heat detection.
