What is Alta CONCEPT PLUS?
Alta EDGE
Alta EDGE sires are the newest, most cutting-edge genetics at Alta. These sires excel for a given genetic index or possess specialized traits that set them apart and are known to be sires of sons, which means they are making the biggest impact on the entire Holstein or Jersey breed.
G-STAR
G-STARs are Alta's genomic sires that do not have milking daughters yet. These sires are specifically chosen to perform in progressive dairy environments and help you fast-forward your genetic progress.
FUTURE STAR
FUTURE STAR sires help you create more pregnancies and live, healthy calves. These sires have the high fertility Alta CONCEPT PLUS status and are known for their low Sire Stillbirth value.
PROVEN STAR
PROVEN STAR sires are daughter-proven. These sires have more reliable proofs because it combines genomic data with herd performance records from his milking daughters.
Alta CONCEPT PLUS
By Definition
Established in 2001, Alta CONCEPT PLUS has grown to become one of the industry's most reliable and accurate sire fertility evaluations. Built with accuracy in mind, it uses real pregnancy check data from progressive dairies across North America to determine whether each Alta sire creates more or fewer pregnancies than the average bull. Based on this data, sires could receive one of the three Alta CONCEPT PLUS designations: CONCEPT PLUS DxD (conventional on cows), CONCEPT PLUS 511 (sexed on heifers), or CONCEPT PLUS BxD (beef x dairy).
The accuracy of the evaluation remains high because it accounts for key factors that affect conception rates, such as semen type, herd, lactation, season, and variation from breeding codes or technicians. This means you can trust that Alta CONCEPT PLUS sires will help you create more pregnancies.
