Temperament and Performance of Beef Cattle

For over a century, the word temperament has been used to define the fear-related behavioral responses of cattle when exposed to human
handling. As cattle temperament worsens, their response to human contact or any other handling procedures becomes more excitable. Within the beef cattle industry, producers select cattle for temperament primarily for safety reasons. However, recent studies demonstrate that cattle temperament may also have productive and economic implications to beef operations. This article will review some of the detrimental effects that excitable temperament has on productive traits of beef cattle.

Evaluat ing Temperament in Beef Cattle

Temperament defines the fear-related behavioral responses of cattle when exposed to human handling. As cattle temperament worsens, their response to human contact or any other handling procedures becomes more excitable. Besides personnel security and animal welfare, temperament has significant implications on cattle performance (see BEEF021 - Temperament and Performance of Beef Cattle). Therefore, evaluating cattle for temperament can be used as a management decision tool to enhance overall safety and productivity of beef operations. This article will review some of the most common and practical methods used to assess temperament in beef cattle.

How to Interpret Sire Summaries

Selecting a bull is one of the most important management decisions a beef producer makes. Since it is possible for a bull to sire 25 or more calves in each calf crop, the bull has much more influence on the genetic makeup of the herd than does the individual cow. Before selecting a bull, every producer needs to establish long-term goals for the herd. The decisions made in bull selection today will be evident in the herd for years to come. Therefore, you must establish breeding goals and stick with them. A successful beef cattle breeding program is a long-term commitment with careful planning, evaluation and re-evaluation of goals and progress.

OSU Across Breed EPD Calculator

The OSU Across-Breed EPD calculator is a Microsoft Office Excel® Macro-Enabled Worksheet. It has been formatted to run most efficiently in Excel 2016. However, an alternative version that will function using older Excel versions is available. In order for all of the features to work, macros must be enabled. The OSU Across-Breed EPD calculator can be downloaded here or contact your local OSU Extension Office. Data for the program will change yearly according to the most recent USMARC AB-EPD data. Therefore, the software program will change yearly as well. New versions will be made available through this website.

OSU Across Breed EPD Calculator - Instructions for Use

The OSU Across-Breed EPD Calculator is a tool to help commercial cattlemen evaluate and compare sires of different breeds using adjustment factors generated from the MARC data. The program allows producers to compare sires on a basis that is most familiar to them. For example, if the producer has historically purchased Limousin bulls, but has decided to purchase Charolais bulls, the program will allow the producer to generate EPD values for the Charolais bull that are equivalent to Limousin generated EPD values. This will allow the producer to compare his existing bull battery to the potential Charolais bulls for sale. Likewise, the program also gives the producer the option to enter EPD values a potential bull should have using EPD values of a familiar breed, in this example Limousin, basis. The program can then generate the EPD values for those traits as would be seen in the sire catalog for the Charolais bulls.

Reproduction for Next Year Starts Now

You are probably wondering how this applies to you if your cows are still pregnant and calves aren’t expected just yet. Let’s take a few minutes and review events prior to and after calving that have an impact on subsequent reproductive processes (and calves).
