Drying Off Procedures / Post Dry-off Mastitis

VetEnt Blog
Category: Uncategorised

It is really important to pay attention to the details when drying off cows. If you are unsure if your technique or plan is top notch, please give one of our vets a call and let us talk you through best practice administration and answer any questions - it could save cows lives and dollars! 
Top Tips
The best time to insert Drycow or Teatseal is directly after the cups come off. That way hopefully the milking process has flushed any bugs in the canal and cistern out with the milk, and there hasn’t been opportunity for any more bugs to make their way up into the teat canal. Also the teat ends are probably at their cleanest, making cleaning them with teat wipes far easier. 
If you still wish to milk cows and send them out to a paddock for a couple of hours before bringing them back in for drycow or teatseal, the risk of mastitis is higher, but there are a few things you can do to minimise that risk:
  • Make sure every cow is thoroughly teatsprayed, with a high concentration teatspray. 
  • Walk cows the shortest distance possible, very slowly, to avoid splashes. 
  • Avoid very wet, muddy or contaminated races/yards. 
  • Use a paddock with a good cover of clean, dry grass. 
  • If the herd is large, try to bring smaller groups into the yards at a time so they are not standing around in muck. 
  • Make sure ALL staff administering dry-cow or teatseal are trained in best-practice hygiene. Please ask any one of our vets or techs to demonstrate this to you if you are unsure. 
What to do if you get cases of mastitis after administration? 
Firstly, cases of introduced infection generally occur within 48hrs of administration; these cows are often sick and may have a watery, tea like mastitis in either a hot swollen quarter, or a cold discoloured one. These cows go downhill quickly.  It’s important to check cows twice a day for the three days after administration so any sick cows can be brought in and treated as soon as possible. 
We advise that if a quarter is hot, swollen or the cow is sick, you strip the quarter, take a sterile milk sample and bring these samples in to the clinic for culture. Then call the clinic straight away to speak to one of our vets about the best course of action. The earlier a cow is treated with the right course of treatment the higher her chance of cure and survival.

Getting value from your 2019 Dry Cow Consult

VetEnt Blog
Category: Uncategorised

As the hot weather continues, some farmers are beginning to dry off parts of their herd. This is a good opportunity to reflect on your upcoming 2019 Dry Cow Consult and begin thinking about how you can get the best value from it this season.

You should be aware about the recent focus on judicious antibiotic use to slow down the development of antimicrobial resistance,  and we all have a part to play in this.

It is likely that in the not too distant future vets won’t be able to prescribe dry cow antibiotics without sufficient data to justify their use. Similarly, blanket dry cow for a herd at drying off is no longer an acceptable practice for the majority of farms. Not having adequate or sufficient data to choose cows for selective dry cow therapy is not a reason to do blanket dry cow therapy.

BVD

VetEnt Blog
Category: Uncategorised

With all of the hype recently regarding M.bovis there is even greater appeal for keeping a closed herd where possible. With this in mind, it is just as important to ensure the animals you are keeping for replacements are healthy and disease free. At this time of year it is as relevant as ever to address the ever present issue of BVD infection on farm, and it’s impacts on breeding and rearing replacements.

BVD is one of the major diseases affecting dairy cattle across the country and is responsible for a staggering loss in production. It is estimated around 80% of dairy herds in New Zealand have been exposed to BVD virus and the disease alone is estimated to be responsible for a loss of $70,000 annual for an average sized dairy farm.

BVD is a viral infection which causes many non-specific clinical symptoms ranging from diarrhoea, ill thrift, abortion or weak calves to the suppression of the animals immune system. It spreads very easily between animals from nasal discharges, milk, faeces or mating. If a pregnant animal becomes exposed to BVD in the first four months of pregnancy she will produce a calf that is persistently infected (PI). This animal will shed the virus throughout its life and will be the main source of infection on the farm.

Ransomware attack update

VetEnt Blog
Category: Uncategorised

The data being blocked following a cyber-attack on Saturday has now been recovered, and systems should start to come back online in the next few days. We are proud of our teams for carrying out the same wonderful service they always do, and for taking the make-shift changes in their stride.

On Saturday 15 September, we, Veterinary Enterprises Group Limited, and our subsidiaries, were victim to a ransomware attack. The attack caused all of our files, email accounts and customer database to become inaccessible. Ransomware is a type of malicious software which blocks or threatens to destroy a victim’s data unless a ransom is paid. In this case, the data was not taken, but the malware was blocking us from accessing it.

The data in question has now been recovered, and our IT team is rebuilding and reinstalling the systems which were compromised.

Category: Uncategorised

Sunday, 16 September 2018

At approximately 11pm yesterday, Saturday 15 September, we, Veterinary Enterprises Group Limited, and our subsidiaries, were victim to a ransomware attack. We discovered the attack at 10am this morning (being Sunday). The attack has caused all of our files, email accounts and customer database to become inaccessible. We’ll still be delivering the same service, but we’ll be going the manual route with calls, pens and paper until we get access back.  

Ransomware is a type of malicious software which blocks or threatens to destroy a victim’s data unless a ransom is paid. In this case, the data has not been taken, but the malware is blocking us from accessing it. We want to reassue all of our clients that we are working non-stop to regain access, and that client and patient data is safe. Their data, and the data of their pets and livestock, is our first priority.

Category: Uncategorised

Pink eye is a highly contagious disease that can spread through your beef herd like wildfire, and cause significant production losses. Spring through to late summer provides the perfect conditions for Pink Eye to establish through a herd.

What is it?

  • Caused by Bacteria Moraxella bovis (different to sheep pink eye).
  • Highly contagious eye disease.
  • Affects all ages of cattle but affects younger cattle more.
  • From exposure to infection takes 2-3 days.

"That cow’s got mastitis, What should I treat her with?”

VetEnt Blog
Category: Uncategorised

This is a question we commonly get asked, as there are many many different choices when it comes to drugs to treat mastitis.

1. Should I treat her at all?

Firstly, slight changes in milk colour and positive reactions on the RMT, even the odd fleck in the milk do not necessarily mean the cow has an infection that requires treating. It does indicate she has an increased cell count but not necessarily an infection. These cows may be only just out of the transition milk period and just require a bit more time for the cell count to return to normal, or they may have had an infection, been treated or self-cured and the cell count still needs time to come back down. Feel the udder: a hot or hard quarter is indicative of an active infection that requires treating. Secondly, if this is a cow with a chronic high cell count and a history of recurring mastitis, would it be better to cull her instead?

Drenching Dairy Cattle... The myths exposed!

VetEnt Blog
Category: Uncategorised

There is a lot of misinformation out there on drenching dairy cows for gut parasites, so let us set the record straight…

Myth 1: Drenching dairy cows results in milk production increase because it kills the worms that are living off the cow’s reserves: The immune system of the cow is very good at fighting off gut parasites. A cow will hardly ever pass worms in its faeces and contaminate pasture, despite continually eating parasite eggs. So in most cases, when a cow’s immune system identifies the parasites in the gut, it kills them off. The immune system has a cost however, and takes up energy. This is where drenching is likely to have most of its effect – it gives the immune system a break and saves that small amount of energy that can then go into milk. It has also been demonstrated that cows with parasites in their stomach actually eat less – they can make them anorexic! So treating them to wipe the slate clean is likely to improve appetite, and enable a potential positive response.

Myth 2: Treating my dairy cattle does not provide any benefits: This assumption is understandable, and from some aspects correct. Treating adult dairy cows with a pour-on does not alter the reproduction or body condition of these animals. But more often than not, Eprinex treatment has resulted in a milk production response. There are numerous studies which identify a milk production response following Eprinex treatment. However, the amount reflected in milk production is very small and hard to see. So here is where you need to trust us! There have been two New Zealand studies that have identified a response of 0.03 kg MS/cow/day – 30 grams a day! On a per day basis, this is hard to comprehend. However, this effect carries on for at least 150 days after treatment – the equivalent of a minimum of 4.5 kg MS/cow for a one-off pour-on.

Why do we lose lambs?

VetEnt Blog
Category: Uncategorised

In New Zealand it is common to lose 15% - 18% of lambs before they are tailed/docked...

The majority of these losses happen around the time of birth, with many lambs being born alive. There are many reasons why we lose lambs. Southerly storms are obvious culprits but diseases and deficiencies are harder to pick by eye.

To work out your level of losses use this formula:

Triple Drench Resistance

Category: Uncategorised

Imagine a day when you have worms in your lambs, they are dying and you have no way to treat it... it’s happening... and it poses a huge threat to farming as we know it.

 

It’s been spoken about for along time and a lot of us haveburied our heads in the sand and denied that it could ever happen to us. It’s happening in the Maniototo and after speaking with vets from all over the country at the NZVA conference I am assured that it is happening nationwide, in much higher numbers of flocks than we expected, in ALL sheep breeds, and to “good” farmers. This is a big deal, and we need to start being proactive now to prevent this from ruining the future of sheep farming in the Maniototo.
