Cow wearables are no longer a novelty on New Zealand dairy cows. With over two years of collar analysis under our belt, I thought it appropriate to share a snippet of findings and trends we have picked up while working with client data. ‘Days the First Heat’ vary between farms (and first calvers always take […]

Off the back of drought conditions and a subsequent lack of feed, there are some lighter ewes around the countryside, but, if managed correctly, […]

Calf scours in New Zealand is commonly caused by any of the following: rotavirus, cryptosporidium, E.coli, coronavirus, salmonella and coccidiosis. As well as infectious causes of scours (diarrhoea), nutritional scours (as a result of various stresses, milk type changes) can also be pretty severe.

Hopefully, the weaning process has gone smoothly this year and, despite the recent dry conditions in many regions, with careful planning and feed management, you have still achieved some decent autumn growth rates in the fawns.

“UBAC®,” is an exciting development in treating mastitis which is likely the largest cost to the New Zealand dairy industry. It was estimated to cost approximately $180 million for the 2005/2006 dairy season (National Mastitis Advisory Committee, 2006). While several factors can influence the costs per cow on an individual farm, Compton and McDougall (2011) estimated […]

The New Zealand Veterinary Association (NZVA) has as its goal that, by 2030, New Zealand will not need antibiotics for the maintenance of animal health and wellness. One may ask just how will this be achievable? Antibiotics have revolutionised the health and well-being of both humans and animals during the 20th century. But 96 years […]
