What is J-BAS?  

LOCAL INFORMATION SESSIONS

An industry-driven approach to Johne's Disease in cattle has led to a new tool called J-BAS (Johne's Beef Assurance Score) to help beef producers manage the risk to their herd. 

Information sessions are being held locally to provide beef producers with an overview of the new approach, the J-BAS scoring system and what actions you need to take before 30 June. 

Topics to be discussed include

  • What is Johne's disease and why is it important?
  • What has changed in the way BJD is managed?
  • How will the "market-driven" approach work?
  • What is the "J-BAS" scoring system?
  • What needs to be done to maintain a certain score?
  • What deadlines are in place?

Information session times

ORANGE - Monday 26 June 2017, 10am Small Room, Orange Agricultural Institute - Training Centre, 1447 Forest Rd, Orange.

MOLONG - Tuesday afternoon 27 June 2017, 1.30-3.30pm - 22 Riddell St, Molong

Please call 63618388 to make a booking. 

02 Limping lambs
SetWidth600-limpin-lambs

Rain, beautiful rain, leads to wet pastures that lead to wet feet that lead to sore feet that lead to lameness. And lameness is the bane of all sheep farmers!

An animal suffering from lameness is less able to graze and compete for feed. The consequences of lameness include:

  • Loss of weight and condition
  • Lower lambing percentages
  • Lower birth weight and hence reduced lamb viability
  • Reduced growth rate in lambs
  • Reduced milk production
  • Lower fertility in rams
  • Reduced wool growth
  • Costs associated with the treatment and control of the disease 

Already this year we have seen a number of cases where the effects of lameness have been quite severe and this is before warmth adds a complicating and accelerating factor to the equation! We have seen lame rams with poor testicular tone and therefore lower fertility leading to poor conception rates, and poor doing ewes that have been limping away from their poor doing lambs.

Lame sheep need to be examined to exclude footrot. This is imperative as footrot is a notifiable disease and any suspicion of the disease needs to be investigated. Luckily often lameness is caused by foot abscesses, either toe or heel and the ubiquitous scald. Foot abscess can be confused with footrot as both develop from scald (or interdigital dermatitis) and both can cause severe lameness; and they love it when conditions are wet.

If you are in any doubt as to the reason for your lame sheep, call us for help with diagnosis and treatment.

03 J-BAS deadline looms - 30th June
SetWidth600-JBAS

Cattle in a Protected Zone and/or Beef Only, are eligible to claim a J-BAS score of 7 until the 30th June 2017.

From November 2016, Cattle MAP herds have transitioned to a J-BAS score of 8, the highest assurance level, until 30th June 2017. Any MAP herds wanting to continue with the higher assurance score should resume any testing that may be required. The transitional arrangements expire on the 30th June 2017.

From the 1st July 2017, to retain scores of 7 or 8 those transitional herds must have in place a property biosecurity plan which:
• Addresses the elements of the JD checklist and
• Is endorsed by a veterinary advisor.

For ongoing retention of J-BAS score 7, the herd must undergo triennial Check testing (50 animals) with negative results. The first round of testing must be completed prior to 30th June 2018.

From 1st July 2017, herds that don’t have a vet-endorsed property bio-security plan in place can no longer claim J-BAS 7 and will lapse to J-BAS score of:
• 6, if they have a biosecurity plan that addresses JD risks but is not vet-endorsed, or
• 0, if they don’t have any biosecurity plan in place that addresses JD risks.

A herd which lapses from the transitional J-BAS 7 because they’ve failed to implement a vet-endorsed biosecurity plan can recover their score before 30th June 2018 by:
• Putting in place a vet-endorsed biosecurity plan, and
• Undertaking a Check Test (50 animals) with negative results.

Therefore, herds which want to retain J-BAS 7 should:
• Prior to 30th June 2017, put into place a vet-endorsed biosecurity plan, and
• Prior to 30th June 2018, undertake a Check test.

04 Caring for the geriatric horse
SetWidth600-geriatric-horse

Compared to many other domestic animals, horses have relatively long life-spans, with many living well into their 20s and 30s. Some horses will even maintain productive careers into their 20s. But just like humans, as horses age, their needs change and extra care may be required to keep them in best health.

Teeth
Regular dental care by a qualified veterinarian is important for all horses, however it is even more critical for older horses. Problems may arise as teeth can become worn, overgrown, or decayed resulting in mouth pain and tooth loss. This can lead to difficulties in chewing feed and an inability to adequately absorb nutrients, often resulting in a gradual loss of body condition.

Metabolic disorders
Conditions such as Cushing’s disease and equine metabolic syndrome can be more common in older horses, and can wreak all sorts of havoc on your horse’s health. We are able to diagnose these conditions and they are often easily controlled with medications and/or nutritional management.

Lameness
Older horses may seem stiff and sore. Wear and tear over the years can lead to arthritis which can affect one or many joints. There are ways to improve the comfort of horses suffering from arthritis and we can help you decide on the best options.  

Prevention is better than cure! Older horses should be seen by a vet for a health check and dental every 6-12 months. 

05 Sheep mustering by drone

Drone technology has the potential to improve many aspects of farming - and make them more fun! Here's a video of a New Zealand producer herding sheep by drone, prior to the arrival of bike and dog on the scene.

06 The whats, whys and hows of hoof abscesses
SetWidth600-hoof-abscess

Hoof abscesses are one of the most common causes of sudden, severe lameness in the horse. A hoof abscess is an infection in the sensitive tissue of the hoof, which develops into a pocket of purulent material (pus) within the hoof capsule. Whilst the volume of pus is often only quite small, the pressure build-up that it causes within the hoof capsule is extremely painful and often results in significant lameness.

Signs of a hoof abscess can include:

  • Severe lameness (often quite sudden in onset), and some horses are reluctant to bear any weight at all on the affected leg
  • Heat in the foot
  • Swelling of the leg

We will examine your horse for an increase in the pulses to the foot (throbbing) and will use hoof testers to help isolate the painful area.

Treatment usually involves achieving drainage of the pus with a hoof knife. Soaking and poultice bandaging the foot will help to further encourage drainage. Pain relief is important however antibiotics are not normally required. It is important to ensure your horse’s tetanus vaccination is up to date as this is one of the most common ways that a horse may contract tetanus.

Call us if you're worried about your horse's hooves.

07 Do cows need sleep?
SetWidth600-cow-sleeping

No, this cow is not dead, she's having a rest by the creek.

The short answer is: yes they do.

The importance of cow comfort and its relationship to general health is now widely accepted. Cows go through similar patterns of sleep to humans – drowsing, non-rapid eye movement and rapid eye movement (REM). Ideally, cows will lie down for approximately 14 hours per day. During that time, cows will have around 30 minutes of REM sleep. When cows are laying down, blood circulation through the udder increases by up to 30%, which increases milk output. 

There are studies currently underway where sleep is measured in cows using an EEG (a non-invasive way of measuring brain activity), to try and learn more about cows' sleep patterns, and how they impact other important bodily functions. There have been many studies in other animals looking at the effects of sleep and sleep deprivation.

Mice which are sleep deprived for 24 hours experience a reduction in lymphocyte count and function, impacting their ability to fight disease. In cows, sleep enables the immune system to function better when a disease is encountered. It is also likely that sleep impacts production, as a reduced immune function causes cows to shift resources from production to fighting disease. Cows may even prioritise lying down before feeding! We also know that laying allows the hooves to dry out and rest which is important to prevent lameness.

As more data becomes available, strategies will be developed to improve cow health, welfare and production. For the moment, let the laying cow lie.
