Project Type: Trust

Start Date: Apr 01, 2005
End Date: Mar 31, 2010

Objective:
Calculate and improve the national evaluation for calving ease and contribute to improved international evaluation of calving traits through cooperation with Interbull. Improve the quality of the reporting of calving ease data and investigate evaluations for stillbirth.

Approach:
Evaluations will be calculated semi-annually; procedures to improve evaluations by excluding herds with abnormal distributions of calving ease scores will be investigated. Ways to account for skewness in international evaluations will be developed for use by Interbull. Data quality will be improved by identifying herds with reporting problems for field staff and using within-herd identification to improve matching of data with existing pedigrees. Data on stillbirths will be requested.
