Using Minda data to diagnose opportunities for reproductive improvement – Jair Mandriaza

Jair showcased the latest in the LIC statistics for the 2023/24 season. These results where compared against previous years with discussions looking at the use of wearable and none wearable herds.

The data set outlined the national ranking, with cows split out into top quartile, 2nd 3rd and bottom, reviewing 6week in calf rates, 3 week submission, conception rate, not in calf and kgMS/cow.

Jair highlights the impact on reproductive performance and milk production “if milk production drops for longer than 4 days in a row, reproduction is negatively impacted”. This season has shown a more constant pastural protein levels, which may have impacted the consistency and results of this season.

Jair lives with his wife Mayara and kids in Te Awamutu where he is based. Has worked as a Reproduction Advisor for LIC for the last 13 years supporting staff, doing education and extension work. He has lived in NZ for 18 years, migrating from Brazil where he had a Veterinarian degree and specialised in Embryo Transfer work
