Learning Outcomes:
On completion of this module students should be able to:Clearly and concisely explain the derivation of the total merit index for dairy cattle in Ireland and how it can be used in a herd breeding programme to maximise genetic gain; Understand the consequences of application of crossbreeding to the Irish dairy industry;Describe how molecular tools, with particular emphasis on genomic selection, can be utilised in national and herd breeding programmes;Outline a comprehensive management programme for cows and heifers in seasonal-calving herds to maximise fertility at subsequent breeding;Describe various targets for fertility measurements, and have a thorough understanding of how to achieve these targets;Describe the principle disorders that negatively impact herd reproductive performance (e.g. anoestrus, uterine infections), know how to identify cows within a herd at risk of these disorders, and outline therapeutic strategies to minimize their impact; Understand synchrony programmes for cows and heifers. Examine herd fertility performance by using fertility records to identify problem areas and identifying strategies for improvement.
