GENETIC
TYPE SUMMARY
|
This
is an objective linear evaluation of a bull's transmitting ability
for various physical traits.
GTS
- Describes differences between bulls'
progeny and does not attempt to classify cattle based on an
ideal animal.

STA (Standard Transmitting Ability) -
A standardized measure of sire's transmitting ability for a
given trait.
STAs - indicate how bulls compare, or
relate t each other, for each trait included in the evaluation.
STAs - also allow you to determine where
a bull falls within a given population for each trait. A bull
with an STA of 0.0 is average for that trait compared to all
other bulls evaluated. For a given trait, the majority of the
STAs on all bulls evaluated will be near 0.0. In fact 68 percent
of the sires' STAs should fall between -1.0 and +1.0, with 99%
between -3.0 and +3.0.
Head
(Progeny Number) - Provides a measure
of accuracy by indicating the number of bulls' progeny that
have been evaluated for a given trait.
Stature - Evaluation of progeny
frame size, based on hip height. Higher STA indicates taller
size.
Capacity - Progeny
evaluation combines depth of the fore rib with spring of rib
and width of chest floor as well as depth of flank. Higher STA
indicates larger capacity.
Body Length - Evaluation
of progeny length from withers to pins. Higher STA indicates
longer body length.
Muscling - Progeny
evaluation combines width rump and hindquarter, with secondary
consideration given to forearm muscling. Higher STA indicates
more muscling.
Rear Leg Set - Evaluation
of progeny rear leg structure, with STA near 0 being ideal.
Higher STAs tend towards sickle hocked; lower STAs tend towards
posty.
Feet and Pasterns - Evaluation of progeny length
and strength pastern and foot angle. Higher ST indicates stronger
pastern with more depth of heel.
Femininity - Evaluation of daughters; angularity
and their ability to carry condition without becoming coarse
and masculine. Higher STA indicates more femininity.
Udder Attachment - Daughter
evaluation combines fore udder attachment, rear udder height,
rear udder width, and center support. Higher STA indicates stronger
attachment.
Udder Depth - Evaluation of daughters' udder depth
from top of fore udder-to-udder floor. Higher STA indicates
higher, better supported udders.
Teat Size - Evaluation
of daughters' teat size, including length and diameter. Higher
STA indicates smaller teat size.
Ave. Eye Pigment Score - The evaluation
of progeny eye pigment. Higher score indicates more eye pigment,
measured on a score from zero to nine. |
