Use Of An Activity Monitoring System As Part Of The Cal Poly Dairy Breeding Protocol, Trevor Nutcher

Dairy Science

The objective of this study, is to determine the effectiveness of an activity monitoring system as an integral part of the Cal Poly Dairy breeding protocol. Dairy herd reproductive efficiencies have dropped in the past 40 years. Increased milk production, and genetic advancements towards more milk production, have led to reproductive rates declining. An advanced breeding program is needed to become more efficient in this area. The study consisted of the evaluation of one option, Heatimeā„¢ by MICRO Dairy Logic, and comparing it to the commonly used programs in dairies today such as synchronization methods, pedometers, and other electronic detection ...
