Research Program

My research is in the area of applied cattle reproduction with an emphasis on fertility and nutrition. The focus of my research is to develop a systematic breeding program for dairy cattle to increase fertility rates and improve reproductive and economic advantages of artificial insemination (AI) on dairy farms.

Using exogenous reproductive hormones (gonadotropin-releasing hormone, prostaglandin F_2a, estradiol-17b, progesterone), we attempt to develop new systematic breeding program (or improve upon the existing breeding program) to provide an organized and efficient approach to administering artificial insemination and improving reproductive efficiency in dairy cows through increasing heat detection efficiency and enhancing conception rate.

Amin Ahmadzadeh

2006 UI Excellence in Teaching Award

Amin Ahmadzadeh, associate professor of animal and veterinary science, came to the University of Idaho in 2000. Ahmadzadeh has been a main contributor to the resurgence of the dairy science program at the University of Idaho. He has successfully secured grants supporting research related to the dairy industry. Ahmadzadeh also helped re-establish the dairy judging team after its five-decade absence. He coaches the Dairy   Challenge Team, the capstone of a dairy management degree, and serves as adviser to the University’s Dairy Club
