The Brahman Herd Improvement Records – BHIR – Program has been specifically designed for Brahman cattle and is a systematic method for identifying the genetically superior individuals in a breeding herd. The program provides a comprehensive profile of your herd through data you and other breeders across the country submit. BHIR is a valuable tool and should guide the progressive cattleman in decisions on management, culling and selection of seedstock by identifying those animals that excel in the following traits of economic importance: REPRODUCTIVE EFFICENTCY; GROWTH RATE; MOTHERING ABILITY; LONGEVITY; CONFORMATION; DISPOSITION.

A sincere effort has been made to design BHIR to enable Brahman breeders to maintain a complete set of records of performance and production with minimum effort and maximum simplicity.

The first step toward BHIR participation is the accurate recording of the birth and subsequent growth of all calves born in a herd. Only after birth dates (and birth weights, if possible), weaning weights and weaning date have been recorded for a group of calves can they be enrolled in BHIR. All of this information is submitted on the Application for Registration and BHIR Enrollment form.

Ultrasound Scanning How To

The American Brahman Breeders Association encourages the gathering of carcass ultrasound data to assist producers in the improvement of carcass quality within their herds and ultimately the breed.  This data will be entered on the animals file, sent to the producer in a usable format and incorporated into the genetic evaluation for the calculation of EPD’s. This tutorial was produced to help walk breeders through the ultrasounding process. For more information on booking a UGC certified technicians, submitting  data or on the BHIR program view the Ultrasound Guidelines or contact the  ABBA office at 713-349-0854.


Formation of Contemporary Groups

The formation of contemporary groups is necessary for the comparison of animals and to place them on an equal basis for the evaluation of genetics.  This article by Lauren Hulsman gives an overview of the process and logic behind the forming of contemporary groups.

Fundamentals of Expected Progeny Differences (EPDs)

This article by Darrh Bullock from the University of Kentucky describes the basics of EPDS, how they are generated, how to compare sires with different EPDs, and what different accuracies really mean.


Accuracy for an EPD may range from 0.0 to 1.0. As the accuracy approaches 1.0, the EPD is more reliable and changes less in the future as data is accumulated. Accuracy can be rated as follows:

LOW – 0.0 to 0.50
MEDIUM – 0.50 to 0.75
HIGH – 0.75 and above
