It’s a commonly held view that calving cows in autumn is much easier than the more common spring (it’s really winter) calving. But why so? Or, more importantly, is it, in fact, actually easier – or does it just seem that way because the sun is out, the days are longer and it’s not freezing cold? […]
Once sporidesmin pasture spore counts are above 20,000/g nutritional strategies are a vital tool to reduce the impact of facial eczema in a herd or flock. The use of zinc in the diet of grazing stock, as a drench, in water or in feed, has long been recognized as one of the most effective methods of minimizing the impact of facial eczema. […]
Lameness in dairy cows is a multi-faceted problem. It is also highly misleading, often the occurrence of lame cows is not directly associated with the cause – resulting in further confusion.
The team at Sollus put together the 3 R’s of lameness prevention. Management of these R’s is critical for success. […]
New Zealand dairy is unique when it comes to nutrition. Not just because it is largely grass based. We see similar industries in Australia, Chile, Ireland and even parts of Europe and Japan in the summer. The uniqueness stems more from having grass as the most cost effective energy source; plus the fact that the industry tries to maintain a seasonal calving program. […]
“The headline might sound extreme and it’s only one possible cause of many on farm, but MPI have recently published an ACVM Guideline highlighting the probable link between magnesium oxide (MgO) and salmonella, and It could be happening to your cows.” […]
“For the vast majority of New Zealand dairy herds it is dry off time, or at least rapidly approaching…” […]
“Death, taxes and down cows do not all have to be certainties in a dairy farmer’s life.
As dairy farmers you do not have to accept that this is a reality, and by changing your focus on farm from treating sick animals to prevention you can remove one of the ‘certainties’ from the list, making dairying more enjoyable and more profitable.” […]
“This energy loss results in lots of the negatives associated with the larger cows, including negative energy balance, poor fertility and even ketosis. Furthermore, the genetic potential of the Holstein Friesians means that we cannot supply this energy requirement and this often manifests itself in low BCS.” […]
“While Dairy NZ has done an excellent job of explaining the use and benefit of magnesium before calving, many farmers still have questions about their cows’ health at farming. There are some interesting things to be considered in this space.” […]
“We know that herds with high incidence of metabolics have poor health, but is it really related? In fact, published research has shown that milk fever, clinical or sub clinical, directly increases the incidence of many diseases.” […]
