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.

Benefits

The primary benefit of using Alta CONCEPT PLUS sires is to create more pregnancies.

  • CONCEPT PLUS DxD: You can expect a 2%–5% conception rate advantage over the average conventional sire when used on dairy cows. 

  • CONCEPT PLUS 511: You can expect a 3%–7% conception rate advantage over the average sexed sire when used on dairy heifers. 

  • CONCEPT PLUS BxD: You can expect a 2%–4% conception rate advantage over the average beef sire when used on dairy cows.
