## πIn This Guide, You Will Learn:
- How to setup parameters for ECON\IR.
- How to understand the information displayed on the ECON\IR report.
**ECON\IR** is a command verb which displays the predicted future herd inventory for the next 7 months based on:
- Animals currently declared pregnant.
- Cull rates entered.
- The semen type for the sires of conception (SIRC) - conventional, sexed, beef.

ποΈ **NOTE:** Future inventory predications can assist in future semen selection.

## Setup Parameters for ECON\IR:
Follow these steps to get started with ECON\IR and create your future inventory report.
1. Enter **ECON\IR** on the command line.
2. Enter the farm's **Replacement Rate for LACT>1 **- Cull rate for 2nd lactation animals and up.
3. Enter the farm's **Replacement Rate for LACT=1 **- Cull rate for 1st lactation animals.
4. Enter the **Live Female Percentage for Unsexed Dairy Semen** - % of calves born from conventional (unsexed) semen resulting in a live female calf being added to the cowfile.
5. Enter the **Live Female Percentage for Sexed Dairy Semen** - % of calves born from sexed semen resulting in a live female calf being added to the cowfile.

~~**1**~~ **Count **of Milking, Dry and LACT>0
~~**2**~~ **%M** (% milking)
~~**3**~~ **NewIn** (heifers freshening)
~~**4**~~ **Left** (culled cows)
~~**5**~~ **Count** of LACT>1, LACT=1, LACT=0
~~**6**~~ **Total Animals** (inventory)
~~**7**~~ **Avg Milk** (average milk production)
~~**8**~~ **Total CWT** (milk production in hundred weight)
:::
::::
~~**1**~~** Milking, Dry, LACT>0: **Milking is the predicted number of milking cows, Dry is the predicted number of dry cows and LACT>0 is the total of both combined (797+128 = 925).
~~**2**~~** %M** is the percent of cows milking (797/925 x 100 = 86%).
~~**3**~~** NewIn** is the number of LACT=0 that freshened last month.
- **2- **under **LACT=0** is the reduction in heifer numbers due to freshening.
- **2 **under **LACT=1** is the number of Fresh heifers added to **LACT=1** (see Fresh on the left column).
- **2** under **NewIn** for July is the number of fresh heifers added to the milking total from the previous month.
~~**4**~~ **Left** is the expected number of animals to leave the herd (sold or died) and is dependent upon the replacement rates entered. These values will affect the total milking for the next month:
- July milking (789) = June milking + fresh cows - cows dried off - culled cows (797+42-34-16=789).
~~**5**~~** LACT>1, LACT=1, LACT=0: **Total number of cows based on lactation numbers.
~~**6**~~** Total** **Animals**: The total herd size (inventory):
- LACT>1 + LACT=1 + LACT=0 (740+185+413=1338)
~~**7**~~** Avg Milk: **The average milk production coming from test day milk or the page 6 lactation curve data.
~~**8**~~ **Total CWT: **The total milk production displayed in a hundred weight value:
- Milk average x total milking / 100 = total hundred weight (84x797/100 = 669)

β ️** IMPORTANT: **
- **ECON\IR** is not accurate if **heifers **are stored in a different cowfile.
- **Abort rate **is not calculated or considered by ECON\IR.
- **Replacement Rate** (cull rate) excludes pregnant cows.
- Confirm actual DCC at **dry off** matches the DUDRY item value - DUDRY may be given a different name such as DRYOF or DRY60.
- ECON\IR will look for **DUDRY** or another item using CDAT as the Op1 and an Op2 value > 170.
