- Genetics and liveweight gain influence heifer puberty timing
Discover why effectively managing heifer liveweight to achieve an early ‘age at puberty’ affects subsequent performance. Puberty timing may also be an early predictor trait for genetic evaluation of cow fertility.
- Using data for mastitis detection
On-farm technologies can measure individual cow performance and behaviour on a daily basis. Read how these data could be indicative of diseases such as mastitis.
- Disbudding: can we improve local anaesthesia for calves?
Find out about an alternative method which is faster-acting and at least as effective as the current method in preventing the behavioural signs of pain from disbudding.
- Comparing cow breed for profitable grazing systems
DairyNZ’s Olivia Spaans explains how cow breeds’ variable use of metabolisable energy in milk may provide an opportunity for farmers to select cow breeds to match required profit levels.
