Cattle and parasites – what the FEC?

Data from faecal egg counts (FECs) taken from cattle poo samples, and shared by vets in a recent Wormwise forum, has shown Ostertagia worms that are resistant to triple oral drenches in 45% of tests!It’s also known that Cooperia parasites are becoming commonly resistant to double and triple drenches. Fonterra has picked up on this and has added a question about whether you are doing FEC tests in their Animal Welfare Plan – so it’s definitely something our farmers now need to start con...

It’s time to prepare for mating

The key to achieving good repro results is being proactive and addressing any issues before mating starts.Many things go into making mating time successful, here are some to consider: ...

Keeping your pets safe and calm during fireworks

Fireworks can be a beautiful sight, but they can also be stressful for our pets. Here are some simple, practical tips to help keep your animals safe, comfortable, and calm as possible during firework displays.  ...

Understanding ear infections in dogs 

The most frequent type of ear infection canines experience is called otitis externa, which simply means inflammation of the outer ear canal. While dogs with floppy or hairy ears (think cocker spaniels and poodles) are more likely to be affected, it can happen to any dog.  ...

Why is my pet so itchy?

Itching, also called pruritus, is a sensation that makes your dog or cat want to scratch, rub, lick, or chew their skin. While occasional scratching can be normal, persistent or severe itching often signals an underlying issue that needs attention.  ...

Body condition: Calving changes and mating impact

A lot of cows were in great condition pre-calving this year, what we'd consider body condition score (BCS) 5.A loss of one BCS – down to BSC 4 – is expected in the first 7-8 weeks after calving, as the cow adjusts to producing milk and is ‘milked off their back’, while their appetite increases. After this time, cows start to gain body condition again.Remember though, any cows with BCS 5.5 or higher are more at risk of subclinical and clinical ketosis after calving, so don't let them get ...

Metrichecking is an investment worth making

Cows with even mild infections in their uterus at mating cost you money (and time), with more non-cyclers, poorer conception rates, higher empty rates, and fewer days in milk overall. These 'dirty' cows can take up to four weeks longer to get in calf and have empty rates 10-30% higher than 'clean' cows.  Metrichecking is the most efficient way of finding 'dirty' cows to allow treatment. If an infection is detected, we use an intrauterine antibiotic to treat it.   We recommend che...

Disbudding with a dose of compassion 

Disbudding involves carefully and safely burning out the horn buds of calves. Removing the buds means they won’t grow sharp horns as an adult, helping prevent nasty injuries to herdmates and handlers. It's much less painful and stressful on the animal getting them done while they're young, as the buds are still only in the skin level.At Vet Clinic Morrinsville, when we disbud calves we do it under sedation and give anti-inflammatory pain relief (Metacam), on top of using local anaesthetic.Rese...

The big deal with pet obesity

One of the most common issues associated with obesity in pets is joint problems. The extra weight puts unnecessary stress on their joints. This can lead to the progression of joint degeneration and arthritis, causing significant pain and reduced mobility. By adopting careful weight management however, this can sometimes reduce or even eliminate the need for arthritis medications. ...

Spring survival kit

Preparation is key! Ensure you have all all the things you need this spring ready in a handy place for when the calves start coming. ...

Reducing calf scours

Every year, outbreaks of scours occur in calf pens – sometimes on farms with a history of issues, and other times on farms that have never experienced problems before. Fortunately, there are a few strategies we can use to manage calves that reduce the risk of scours and improve sick calves chances of survival.Colostrum feeding is crucial for calf health. Ideally every newborn calf should drink 3-4 litres of ‘gold’ colostrum (from a cow's first milking) within six hours of being born to ens...

Calf shed prep

With spring calving just around the corner, now is the perfect time to assess the quality and readiness of your calf sheds. A well-designed shed not only promotes healthy growth, but also reduces the risk of disease spreading among your calves....

Abortions: How many is too many?

It can be disheartening when you see your cows slipping, especially after all the effort you put in over mating. The reality is, a certain number of slips are inevitable. But it’s still worthwhile keeping an eye on how many you have and trying to avoid those that can be managed out of the equation.  So, what’s normal? It’s common to see about 2-5% of your cows abort, and another 3% may abort unseen.   Some possible causes of abortions in cattle include:Nitrate poisoning....

Acorn poisoning

This poisoning is caused from a substance called ‘tannins’ contained within acorns themselves, but also found in oak tree leaves, young shoots, and even the bark. Stock usually get ill from eating the acorns. Unripe acorns are a lot more toxic, so pay close attention to strong winds bringing down crops of acorns before they’re naturally ready to drop. Cattle and sheep are more likely to ingest acorns in an area when feed is tight, however, any exposure to acorns or oak trees coul...

Salmonella cases locally

We currently have a few herds with confirmed cases of Salmonellosis.  The Salmonella Bovismorbificans strain of this disease causes severe diarrhoea and has been linked to abortions. Other clinical signs of Salmonella in a herd can range from a mild drop in milk production, to deaths from toxic shock in more severe cases.  Changes in diet or stressful events (e.g. transport, calving, or overcrowding) can cause changes in a cow’s gut flora, leading to clinical disease. It’s also bee...

A look at Leptospirosis

Lepto can cause sickness and abortions in some dairy cows, and in others it may cause no symptoms and they simply carry the bacteria and pass it to others. Lepto is likely to be contracted by unvaccinated calves from their first autumn onwards, and can be shed by an infected animal in their urine for years.   As a zoonotic disease, it’s easily spread from animals to humans. There are plenty of people who have had Lepto if you ask around – and they don’t recommend it!  Mild cases ...

Nitrate poisoning in cattle

In the coming months, as plants grow rapidly after a hot, dry summer - while mornings remain chilly and overcast - conditions are ideal for nitrate toxicity. Young, fast-growing grass and recent nitrogen fertiliser application increase the risk. If you’re concerned that a pasture coming up in your rotation may be high in nitrates, it’s best to test it. A cow can die within one hour of eating a high level of nitrates, so prevention is a lot better than trying to deal with the disastrous ...

New DairySmart milk testing machine

We now have a milk culturing incubator with AI reading capabilities in our clinic! This new machine can accurately identify many causes of mastitis after only 1-2 days incubation. It significantly reduces the time lag for results, as there’s no need to send the milk samples to a lab.It also offers a cost-effective test for high somatic cell count (SCC) cows, helping distinguish between Strep and Staph – which could be a real advantage when making decisions coming up to dry-off....

Protect your puppy from Parvo

Parvovirus, or 'Parvo', is a highly contagious viral disease that affects dogs, especially puppies under six months old. The virus affects the gastrointestinal tract (the gut) and in some cases, also affects the heart.Parvo is a serious condition that can be fatal in up to 90% of cases. It's contacted from the faeces of an infected dog. The viral particles are extremely hardy and can survive in soil and on inanimate objects such as clothing, shoes, and surfaces for up to 12 months. Hence, a...

Let's talk about pet dental health

Just like humans, our pets benefit greatly from regular dental care.Oral hygiene is extremely important for their overall health. Without proper care, dental disease can lead to infections and even damage internal organs. ...

Drying off technique

Dry cow season is almost upon us. It’s crucial for the udder health of your girls that the correct technique is used when applying dry cow therapy and teat sealant.  It’s a process that requires a high level of sterility and a lot of patience – especially with those heifers!  Here are some instructions for a gold standard approach to drying off each cow, with the aim of preventing mastitis this dry period....

Controlling Johne’s disease

Given its prevalence, most farmers will have Johne’s disease in their herd at some stage. The first sign of a problem is often watery, green diarrhoea that bubbles after it touches the ground or chronic wasting seen in older cows. If you discover a Johne’s problem in your replacement heifers, it’s likely that your farm has a high burden of the disease bacteria. The more heavily infected cows you have, the more they will continue to shed the bacteria and infect your younger stock. Al...

Trace element testing

With zinc season ending and winter approaching, now is a great time to test your herd’s mineral status, and copper levels in particular.    Cows in late pregnancy and youngstock have the greatest demand for growth, and so are most negatively affected by low trace element levels.   ...
