World Wide Indexes: Meeting Dairymen's Needs the World Over

WWS recognizes that dairymen use different criteria to select service sires, based on their own economic and breeding philosophy goals. WWS has created 6 unique indexes to help farmers refine their selection of bulls from the WWS’ portfolio to best meet their breeding objectives. In addition, WWS has developed a customized index option. This tool offers breeding enthusiasts the opportunity to select the criteria they value and identify WWS bulls that best meet their breeding objectives.

Create Your Own Index

My Index is designed for the breeding enthusiast, the dairyman that wished to create an index based on the specific traits that apply to his breeding philosophy and management system. Users may select one of the existing indexes and customize the traits and emphasis placed on them, or may create their own index entirely, to identify WWS’ bull that best meet their selection criteria.
