Abreviations Fnais : ease of calving RVS : recommended weanling ISEVR : index at weaning (evaluated on performance of calf) Alait : milking ability EVS : producer of elite weanlings Dmsev : muscular development at weaning RRC : evaluated through the bull station Dssev : skeletal development at weaning MAT : mother of bulls HG : height at withers MET : mother of elite bulls LT : length of torso INS : registered HP : depth of chest AIA : A.I. bull LP : with of chest MAG : mother of heifers LE : with at the shoulders MDS : cow with good record but those figures have been altered by a specific problem for ex. aborted or calf died due to accident. LH : with at the hips LB : length of pelvis Ltot : total length LTR : with at the pin bones TP : chest circumference TC : cannon circumference The bull testing station of "La Borie de l’Aubrac". Every year approximately one hundred males are chosen on their individual performance : growth rate, conformation and functional characteristics. At the end of the intake the index is calculated by INRA (French breeding institute) based on daily weight gain weight for age, muscular dev. and skeletal dev. The animals are chosen by a group of breeders appointed by the herd book and AI companies. 3 or 4 are picked by Midatest to go in to AI and the rest is sold to breeders through the station (private sale and auction). What are the selection criteria?. On their mother : fertility : average calving interval ; longevity ; number of calvings, age at first calving, milking ability, ease of calving. On the bull before entering the station : date of birth : preferably mid December to mid March, genealogy, weight at weaning, skeletal and muscular dev. Functional ability. Must conform to the breed characteristics. On the animal at the station : precocity : ability to show an adult format very quickly. Growth rate : weight for age, daily weight gain, monthly weighing and scoring at intake and coming out of the station. Hardiness : feed efficiency on rough forage : ¾ of the ration is hay. Evaluation of the legs after being tied up (5 months on concrete). Calving ability : internal measurement of the pelvic opening. Cross Breeding Aubrac bulls have proven themselves as sires of consistent good quality finishing stock with high grades, and the maternal qualities of the breed make the heifers valuable replacements. 3 bulls are available directly through Irish AI. ROCKHILL URBANO (RLU) PERLOU (PRZ) TURIN (TIN) Urbano and Perlou are available from NCBC. The straws have to be ordered from NCBC ( 046 9541230) or from your inseminator. Turin is available from Gouldings Genetics (086 8396802) Rockhill Urbano is Irish bred by Edward Walsh, Ballintra Co. Donegal and has been selected by the Irish Aubrac Society. His sire Egyptien is easy calving, very fertile, and has good beefing ability. Egyptien has been used very successfully on dairy and suckler cows in Ireland until his stock of straws ran out. Urbano’s dam, Patricia, comes from one of the main herds in France, has good breeding and excellent maternal qualities of ease of calving, milk and a short calving interval.
