Wool Sheep Record Keeping Software

Introduction

This fact sheet should be used in conjunction with the excel sheet available here. The aim of this excel program is to help wool sheep producers keep better lambing and production records. This fact sheet is to be used as a guide in completing the excel records. There are many benefits to raising sheep which can be used for both wool/hair and meat production. For record keeping specific to haired sheep, please visit this fact sheet. If you are considering starting a sheep enterprise, we recommend you visit the fact sheet AFS-3856. AFS-3856 covers information on how to get started, sheep breeds and general production information.

 

Reproductive efficiency

Sheep have the potential for multiple births, especially in farm flocks. Therefore, select twins for replacements when possible. With good management, mortality of twins should not be much higher than that of singles. Keeping good records will help you identify the best ewes and rams in your herd. Measures of reproductive efficiency include age at puberty, fertility, lambing rate and length of breeding season. Reproduction in sheep is strongly influenced by environment. By most estimates, the heritability of reproductive rate is low, but breed differences exist. Fine-wool breeds are highly fertile and have been used successfully in crossbreeding programs to improve reproductive rate. Breeds that have been used under intensive management systems to increase lambing rate include the Finnish Landrace, Border Leicester and Suffolk. Next we will explain how to use the lab record keeping excel sheet.

 

Getting Started

Microsoft Excel. This program is compatible with Microsoft Excel 2010 or newer versions. Earlier versions of Excel are not fully compatible with this program. Using an earlier version will result in a loss of functionality.

 

Macros must be enabled in this program. To learn how to enable macros please visit Microsoft Office Support,

 

For most users, when the spreadsheet is opened, a yellow security warning bar will appear just above the workbook page. Clicking the "Enable Content" in this yellow bar will enable Macros.

 

Saving Files

Sheep Records is a macro-enabled excel file. Excel files are referred to as workbooks. As specific data is entered for each evaluation in Sheep Records, current information can be saved in the workbook by either clicking on the save icon or by choosing SAVE or SAVE AS from the FILE menu. This will update all entries that were made since the last save. SAVE AS option will create a new workbook with the settings entered, while leaving the template or original workbook intact.

 

Using the Software

The Excel sheet will initially open on the user's guide. To navigate from one worksheet to another, use the buttons embedded in each worksheet or the tabs at the bottom of each worksheet. Cells intended for user inputs have white backgrounds. Cells with yellow backgrounds have protected formulas to retain the integrity of the program. Special grey background buttons allow users to sort various information and clear information.

 

Tab labeled Config

You will want to enter the farm name, owner and lambing year to keep track of records from year-to-year, and to provide base information if you share this with others to help with decision making. This information will automatically appear on all of the pages.

 

Tab labeled Lamb Data

Consider printing the Lamb Recording Sheet form prior to lambing season so you can have a hard copy available to keep records as lambs are born. A printable version is available at the end of this fact sheet.

 

The lamb data could be a worksheet that is filled in later from a hard copy record but it is important to know what information is needed to complete the excel form. Notice the farm name, owner and lamb year is auto populated from the configuration worksheet. Some information in yellow cells are dependent on information provided in other worksheets. For example, ewe age is calculated from the birth date on the ewe data tab using a hidden table. The user does not have to do anything for that calculation to happen, other than putting in the ewe birth date, and indicating the ewe ID on the lamb data page. Not all ages will be calculated to actual ages as adjustment tables are based on ewe ages of 1, 2, 3, and 7. For example, a 5 year old ewe will have a listed age of 3 on the lamb data tab or a 10 year old ewe will have a listed age of 7. These adjustment factors are provided by the Sheep Handbook. Adjustment factors used in the adjusted weaning weights include age of dam, type of birth and type of rearing as well as the sex of the lamb. The column ‘Ewe age’ will not be calculated until the lamb birth date is also provided. As you enter information, columns in yellow should populate. However, if you notice “#DIV/O!” in yellow cells the formulas are telling you that no calculation is being made as the information you have entered doesn’t fit the criteria. Consult the user guide, a tab located on the far right, for explanations of abbreviations. Once all lambs have been recorded you may want do a SAVE AS with a different name to save a record of lambing birth date order.

 

Tab labeled Ewe Data

Enter the ewe ID either as a visual tag number such as USDA 840 tags. Those tags can be 15 digits, which can be cumbersome, so using a naming scheme like the last 4 digits or a farm ID such as 645Y (Yellow tag 645) would be a good option. The ewe name column allows for other personal options like actual names such as “Speckles” or “Daisy”. The birth date of the ewe can be entered in any format for example June 1, 2020 or 6/1/2020. The next column is for breed identification. Dam ID and sire ID indicate the ewe’s dam and sire. Service sire is the sire the dam is exposed to and can help minimize close relative matings.

 

Tab Labeled Ram Data

Enter the ram ID in the first fillable column as a visual tag. The next column “ram name” can be used to put a person name such as “Speckles” or “Daisy”. Again, the ram birthdate can be inputted in any format. The next column is for breed identification. The final two columns are for identification of the ram’s dam and sire. Both the ewe data and ram data can be printed at different times of the year for inventory records so these should be updated yearly.

 

Summary

Once lamb, ram and ewe data has been entered hit the refresh summary button as this worksheet helps summarize performance data by age group, sex of lamb, birth/rearing type and ram ID.

 

Once all the data has been entered it is nice to have a print out of the lambing records for the year to store as a hardcopy. When you want to start a new season you will want to clear fields such as clear lambs or clear ewes and clear rams once you hit one of these buttons it has a safety feature to make sure you wish to clear the information. Simply type Y to clear the information.

International Year Letter Code for Sheep helps minimize duplicate animals IDs when using a letter in which the lambs were born in conjunction with a numeric ID (i.e., 101R).

Letters ‘I’, ‘O’, ‘Q’, and ‘V’ are not used as they tend to look like a number when used in a tattoo system.

 

Some managers minimize duplicate IDs by using different color tags.
Utilize whatever system works best for you but remember computers don’t always know what your management style is.

Printable Lamb Record

The below can be printed and taken into the field and then added to the excel sheet later.

 

Sex of Lamb = Ewe, Ram or Wether
Birth/Rearing Type: 1=Single raised as Single, 2=Single raised as Twin, 3=Twin Raised as Single, 4=Twin raised as Twin, 5=Triplet raised as Single, 6=Triplet raised as Twin, 7=Triplet raised as Triplet.
