A Case Study on Farm. Dr. Laura Pattie

Laura has joined PGG Wrightson after a 10-year career as a farm vet. Her passion is all things animal nutrition. During her veterinary career Laura has seen how good nutrition translates into great production, reproduction and animal health outcomes. Laura is a firm believer in setting good foundations of nutrition and building from this base to optimal animal performance. Laura enjoys the challenge of finding practical solutions for the many differing farm systems.

Laura Pattie steps us through her thoughts and expertise around interpreting numbers from a milk docket. Milk protein is defined by many on farm factors but particularly energy intake, as illustrated by Lauras use of real world data from local North Island dairy farms. Laura illustrates these milk fat and milk protein concepts by showing the effects of recent very wet, cold weather, as well as the effects of in shed feeding and maize silage on the milk protein profile over time compared with the previous season for the same farm.  Laura presents rumination data overlaid with vat milk fat % data, and that lower rumination rates are likely associated with lower vat milk fat %. An excellent overview of interpretation of milk urea is provided by Laura, with a good discussion around “how low is too low” for milk urea on farm and how changing in the type of shed feeding feed blends can shift milk urea concentration and milk response by cows. Some interactive discussions at the end allow attendees to provide their own views on milk docket interpretation.
