When spore numbers are really high, zinc is often not enough to prevent damage. What’s more, like many strong medicines, zinc comes with side effects. For example, it can be antagonistic to other minerals, especially calcium, increasing the likelihood of milk fever. With planning these side effects can be offset. There are other means in the tool kit of bolstering immunity and decreasing exposure to spores. […]
For each lactation, a cow can lose around 500 gm of calcium from her natural storage, namely her bones.
This process means that she is mining her skeleton to put calcium and phosphorus into milk. This situation can explain why higher producing older cows are more susceptible to milk fever. This means, like capital fertilizer, we have to put back what we take out. […]
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? […]
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.” […]
Testimonial – Mike Tilleman, South Waikato
In a country where dairy farmers are bought up to make the most of growing and using low-cost ryegrass and clover, it can seem counter intuitive when grass intake is recommended to be reduced, and supplements increased, often at a time of year when grass supply is good. Mike Tilleman would be the first to admit he was like most farmers in that respect when he first kicked off with Tranzsol and Lactisol in his herd’s diet. […]
Testimonial – Gareth Hale, Timaru
The prospect of facing at least 20 down cows every day over calving is the stuff of nightmares for most dairy farmers. But for Gareth Hales and his team this was often the reality. With was the stressful, time consuming and expensive issue of getting those cows back on their feet, and into the herd again. […]
Testimonial – Craig Vanner, Mangakino
Farming on the tough volcanic country around Mangakino means Craig Vanner has learned to tailor his expectations to the limitations of the land. This includes dealing with some tough winters with low growth days and a tendency for the lighter soils to turn dry easily from early summertime.
But for Craig his two biggest issues that had added to the farm’s challenges have been high incidence of milk fever in his 500 head herd over spring-time, and problems getting them back in calf. […]
Testimonial – Hamish Johnston, Timaru
When Hamish Johnston started discussing his herd health problems with Sollus he soon found he was getting more than just the opportunity to buy some minerals to deal with the problem. “When Sollus first rang me and we started talking I soon found we were getting a company that understood animal nutrition very well and was not interested in just selling us some product.” […]
