A pre-mating report shows your herd's cycling rate, in the lead-up to mating. As the PSM (planned start of mating) day approaches, the Day -14, -7, and PSM reports show extra details to help with decision-making.
Early Treatment Calculators
On the bottom of page 1 of the pre-mating report, two calculations are displayed:
DIM Gain From Treatment | Projected impact on the number of days in milk (DIM) if animals are treated. |
Treatment Group | Projected impact on the percentage of animals 'In Calf' at 3-weeks (3WICR) if animals are treated. |
More detail on treatment interventions is provided on page 2 of the report.
Your herd non-cycler projection for cows eligible to treat graph
The first graph shows a prediction of the percentage of cows eligible to be treated on or before the planned start of mating date:
In the example below, on the PSM date, 45% of the herd will be eligible for treatment (133 animals).
In-calf rate in treated vs untreated non-cyclers graph
The second graph shows a prediction of the percentage of animals in-calf after PSM if treated, shown in green:
Basis of the calculations
The calculators incorporate findings from published research and industry analyses:
McDougall et al. reported a 16 DIM difference between early-treated cows and untreated controls.
Later treatment (7 days into mating) produced a smaller benefit of 9 DIM. Zoestis.
A retrospective study of over 8,300 CIDR-treated non-cyclers (Veterinary Centre Ltd.) demonstrated a 47% 4-day in-calf rate from CIDR programs.
For calculation purposes, cow eligibility is set at ≥45 DIM at insemination. Final eligibility should be confirmed in consultation with your veterinarian.
