Helping heifers grow

Written by  Staff Reporters
The data, collected from LIC’s MINDA software, showed that at 22 months, heifers on average are around 4-5% below MINDA guidelines. The data, collected from LIC’s MINDA software, showed that at 22 months, heifers on average are around 4-5% below MINDA guidelines.

Dairy farmers can easily track the performance of their replacement heifers and ensure they reach their genetic potential.

Weighing technology can help farmers to meet crucial heifer liveweights at first mating and calving boosting in-calf rates and increasing milk production, says Gallagher head of animal performance and traceability Brian Rose.

New data from LIC shows that too many farmers are not weighing their heifers when they return from grazing – and are missing out on big genetic gains as a result. LIC believes the impact on farms is huge, leading to poor heifer fertility and production. It means farmers are not maximising their return on investment from breeding the heifer and are risking her first-year production potential.

Rose says while the statistics are not ideal, there is simple technology available that can help. He says electronic identification (EID) and weighing solutions are now able to give farmers accurate information on whether their heifers are meeting the targets.

Each animal’s EID number is scanned using a portable hand-held tag reader or hands-free reader in the yards, which are connected to a compatible weigh scale to collect weights and other livestock records.

The target heifer weights and dates can be imported from MINDA, which means the farmer can see in real time if each individual heifer is on track to meet her targets. If not, it presents an opportunity to adjust management practices accordingly.

Clostridial Disease in Lambs: NZ Vaccination Guide

Although preventable, lamb loss from clostridial diseases during the first year of life on New Zealand hill country farms continues to be an issue. A field trial, where lambs were vaccinated at docking and weaning, demonstrated that vaccination was highly effective, lowering clostridial deaths by 23%. Zoetis veterinarian Dr Victoria Chapman unpacks the importance of robust animal health programmes, vaccination timing and the potential harmful consequences for stock when vaccination isn't given.

BVD Control in Dairy Herds: How to Find & Remove PI Animals

Bovine Viral Diarrhoea (BVD) is estimated to cost New Zealand's dairy and beef industries more than $150 million every year, yet many of the tools needed to control it are already well understood. After more than 25 years in veterinary practice, Andrew Weir, animal health technical specialist at LIC, has seen firsthand the impact BVD can have on herd performance. We asked him about the role of persistently infected (PI) animals and the practical steps farmers can take to reduce their risk.
