General Hints & Tips

Avoid high birth weight EBV’s and select for short gestation length EBV’s. Above all avoid big shouldered, short necked bulls.
* Bull buying guide for self-replacing herds:
In buying bulls for any self-replacing herd, you should generally avoid negative milk EBV’s.
* Buying your bulls using EBV’s
EBVs = BUYER TAKE NOTE, BUT BUYER BEWARE
Beware of misuse of EBV’s when accuracy is not considered.
It is important that buyers should be made aware of the misuse of EBV’s when accuracy is not considered. Eg. A bull with a birth weight of +4.5 with 70% accuracy will have 96% of his calves with a birth weight ranging from +2.8 to +6.2, or a bull with a 600 day weight of +80 with only 70%, then it is suggested that 96% of his calves will have a 600 day weight ranging from +66 to +94.
We have noticed two full ET brothers given the same midparent EBV’s and then eventually end up with a completely opposite set of figures. Some “High accuracy” EBV bulls have had very misleading and drastic changes to their EBV’s, one popular, widely used bull with over 600 Day weight, over a three year period 600 day weight crashed from +70, to +49, then went back up to +70. One now wonders what his 600 Day figure will be next year?
EBV’s are a useful guide and a good management tool, but unfortunately, these mid-parent “paper” figures are being misused by many studs and promoted as a high-tech marketing tool with little explanation about their accuracy.
Basically EBV’s tell us that if the father is 7 feet tall and the mother is 5 feet tall then we expect the children will be an average of 6 feet tall. This may be correct but there is usually little emphasis on the fact that they will also range from 5 ft to 7 ft.
We hope that you have found this Bull buying guide information of use.
