Daily Submission Rates

Repro - Daily Submission RatesUsing the data

This graph shows the percentage of eligible cows that have been mated for the first time, to either AB or natural service, for each day of mating (up to six weeks). 

You can use the graph to see if there is a period of time where things went well or not so well, to help you identify strategies you used that worked well and those that may need tweaking next mating.  For example, if your submission rate significantly drops off on a specific date, take a look at what was happening on-farm around that time to see if improvements could be made.

How to read the graph

The table below the graph shows the 3 week submission rate, and a year on year comparison of weekly submission rates (weeks 1-3).  The 3 week submission rate is the percentage of eligible cows that have been mated for the first time from Mating Start Date (MSD) to day 21 of mating.

MSD is calculated once there are matings recorded on six consecutive days at the start of the mating period.

If MSD cannot be calculated, a planned start of mating date (PSM) is used. The PSM is estimated based on the previous season’s mating start date unless this is the first season since a herd was established. In this instance a default date will be assigned until a Mating Start Date is calculated.

The dotted blue line represents the industry target submission rate.

The solid blue line shows your herd’s daily cumulative submission rate.

The blue diamond is your 3 week submission rate.

Click anywhere on the solid blue line to see the submission rate and number of cows submitted by that point in time, along with the average submission rate achieved per day and an indication whether you are on track to achieve target or not.

Use the group drop-down to select a different group of cows to report on.

Submission Rates by Calving Pattern

Repro - Submission Rates by Calving Pattern

Using the data

Use this graph to compare your 3 week submission rate between calving patterns and assess the effect of calving pattern on your herd’s mating performance.

How to read the graph

The circle on the left shows the proportion of cows that calved by weeks 3, 6, 9, or after week 9 of the calving period.

The graph on the right shows the cumulative submission rate for one or more calving patterns compared with the overall submission rate for the whole herd.

The table gives you a breakdown of submission rate for each calving pattern through the first three weeks of mating.

Rule of thumb: Medium calvers (calved by week 6 of calving) should have a 3 week submission rate within 8% of the 3 week submission rate of the Early calvers (calved by week 3 of calving).  If the gap between Early and Medium calvers is greater than this, think about what are the differences between these two groups of cows, and whether these differences are something you can beneficially influence for next mating.

Click colour blocks on the circle, or click a row in the table to add or remove calving patterns to the line graph.

Submission Rates by Age

Repro - Submission Rates by Age

Using the data

This graph enables you to compare your 3 week submission rate between the age groups of cows in your herd and assess the effect older cows have had on your overall herd reproductive performance.

How to read the graph

The circle on the left shows the proportion of cows aged 2, 3, 4-8 and 9+ years (at their last calving).

The graph on the right shows the cumulative submission rate for one or more age groups compared with the submission rate for the whole herd.

The table gives you a breakdown of submission rate for each age group through the first three weeks of mating.

Rule of thumb: Younger cows are expected to perform better than older animals. The older a cow is the worse their reproductive performance is as an age group.  If your first and second calvers (2 and 3 year olds on the graph) do not have a higher 3 week submission rate than your older cows, look into your young stock management.

Click colour blocks on the circle or rows in the table to add or remove age group submission rates to the graph.

Early Indicator Repat Matings 

Repro - Early Indicator Repeat Matings

Using the data

Use this indicator to track your heat detection performance during the first 17 days of mating. The aim of this report is to give you the ability to evaluate heat detection performance as soon as there are a few days of mating data recorded.  This is based on the fact that cows should not, physiologically speaking, be able to return to heat in 17 days or less. Only a small proportion of short returns is physiologically explainable (8-12 day returns).

The table shows the total number of matings, number of short returns and the percentage of short returns during the first 17 days.

When the number of short returns gets above 13% the indicator will change from blue to red.

Rule of thumb: If your percentage of short returns starts to get into double figures don’t panic, but it is a good time to review your heat detection practices and make changes to reduce the number of short returns.

Return Interval Analysis

Repro - Return Interval AnalysisUsing the data

This report helps to assess heat detection accuracy on farm to help you assess if there are too many invented or missed heats.  This graph is based on returns, and the returns are classified into three categories:

  1. Short – the return occurred between 1 to 17 days after the previous mating
  2. Normal – the return occurred between 18 to 24 days after the previous mating. 
  3. Long - the return occurred more than 25 days after the previous mating

The graph calculates the distribution of the returns and shows what percentage of all of the returns were short, normal, and long.  The target is to have less than 13% short returns and less than 18% long returns.  Any more than this, and the graph will change from blue to red.

The longer the mating period the more accurate this report is.  It is best to wait until day 30 or more of mating before looking at this graph.

If there are less than 50 returns recorded the reliability and accuracy of this report may be compromised and a yellow banner will be displayed above the graph.

Return Interval Analysis by Year (AB Only)

Repro - Return Interval Analysis by Year (AB Only).Using the data

This report helps to assess heat detection accuracy on farm by comparing year on year performance. The report is based on the return interval analysis for each season and compares the percentage of short, normal and long returns for each year’s eligible cows group.
