About the SIMBRA breed
SIMBRA – THE COMPLETE ALL-ROUNDER
“A good bull has a good dam.”
The best Simbra cows are identified for many years already by the SIMSTAR method and are highlighted to the industry as superior in sales catalogues and on the registration certificate by means of their *, ** or *** stars. Awards and promotion (from say * to ***) are based on reproduction, growth (200-day EBV) and milk (EBV) requirements, which are adjusted annually according to the latest breeding values. The Society was the first institution in Southern Africa which identified it’s elite cows according to EBV’s (instead of indices).
The present requirements of *(4 calvings), **(5 calvings) and *** star cows (more than 5 calvings) are high and only 8% of the active cow population meets these requirements.
Bull buyers are strongly advised to buy bulls from star cows.
Star Cow Calculation
Cows that excel with motherly qualities are rewarded with *, ** or *** stars on the registration certificate, auction catalogues and www.simbra.org and are known as star cows.
The criteria for star cows is as follows:
- ➢ 1 Star (*) – 4 Calvings on record, of which 2 calves must have passed inspection and 3 must have a wean weight on record.
- ➢ 2 Stars (**) – 5 Calvings of which 3 calves must have passed inspection and 4 must have a wean weight on record.
- ➢ 3 Stars (***) – 6 and more calvings of which 4 must have passed inspection and 5 must have a wean weight on record.
- ➢ Reproduction: Age at 1st calving and Intercalving Period (ICP) must not be higher than the breed average.
- ➢ Performance: 200day weight EBV en 200day milk EBV must equal breed average or higher. These standards are adjusted annually according to the latest breed averages, dead cows also receive stars according to the performance of their progeny. Details of all-star cows are available on the web.
