Haplotypes Research

The Fertility Haplotype Project aims to detect haplotypes with lethal potential that affect the fertility of cows in the Angus population. Haplotypes under investigation may have different effects based on their location including stillbirths or early calf death. Having a DNA sample on those calves allows us to be more precise on the identification and better understand the haplotype effect.

Haplotype Research FAQs

The report is a page to record basic information to go along with the sample being submitted. While the information is basic, it is hugely helpful to the project, because it provides additional details about the sample.

All DNA samples collected to test deceased cattle for this project will be processed free of charge. The American Angus Association and Angus Genetics Inc. are committed to assisting the membership with the collection of this valuable data. 

No, the reporting and sampling of the calves for this project is voluntary and you will not be penalized if you submit or don’t submit your samples, even if we identify a deficiency in your reported calf’s DNA in the future. 

You are welcome to submit samples from calves from stillbirth, and calves that died before weaning for any reason. Some examples are deaths due to physical deformities, disease or infection, and weather conditions. Some genetic problems might appear as an invisible condition so any death can help us learn and study haplotypes.

Your sample contributes to a long-term research project, so do not expect to receive results back. Parentage information can be provided, but no EPDs will be predicted.
