NZ farmers are using Betty’s artificial intelligence to manage animal health

A New Zealand-made mobile app is being used by local dairy farmers to replace veterinarians. Available on the App Store, the Betty app uses machine-learning algorithms to help dairy farmers diagnose sick cows in their herd.

Farmers using the app are presented with series of questions. The responses combined with regional farm and weather data produce a list of the most likely causes of disease in their animals.

Betty’s creator, Dr Jonathan Wong, said the idea was born out of frustration, while he was working as a dairy veterinarian.

“There are a lot of farmers out there who are reluctant to call a vet early, especially if a problem is perceived to be minor,” he said.

“With Betty we can help farmers decide whether or not their sick cow is an emergency and to take immediate action, or connect them with a local vet if need be.”

The app has been on trial with a core group of 31 farmers, who are providing on-farm feedback to improve its artificial intelligence engine.

“It’s all about experience,” Wong explains.

“While a typical dairy vet sees up to ten cases a day, the Betty AI engine has the ability to assess hundreds of sick cows every hour and is continuously refining her algorithm with each one.”

Samuel Woods, a dairy farmer trialling the app, runs a 600-cow herd in Canterbury.

“The reality is there are many inexperienced workers entering the dairy industry,” he says.

“With millions of dollars worth of livestock to manage, you need to give them all the tools to find sick cows early.”

The Betty app is currently available on the New Zealand Apple App Store.

The long-term plan, says Wong, is to improve the Betty AI engine before releasing it overseas.

“And then, maybe, we’ll release an app for cat owners too!”

British report presses for reduced use of antibiotics in agriculture

Reducing antibiotic use in agriculture is among the key strategies for tackling the growing threat of drug resistance, according to a report into antimicrobial resistance.

An account of the report’s findings on the agricultural use of antibiotics has been posted on

“The quantity of antibiotics used in livestock is vast,” said the report, entitled Tackling Drug-Resistant Infections Globally: Final Report and Recommendations – The Review on Antimicrobial Resistance.

“In the US, for example, of the antibiotics defined as medically important for humans by the US Food and Drug Administration, over 70 percent (by weight) are sold for use in animals,” it said.

The authors said there were circumstances where antibiotics were required in agriculture and aquaculture to maintain animal welfare and food security.

“However, much of their global use is not for treating sick animals, but rather to prevent infections or simply to promote growth.

“Many countries are also likely to use more antibiotics in agriculture than in humans but they do not even hold or publish the information.

“The majority of scientists see this as a threat to human health, given that wide-scale use of antibiotics encourages the development of resistance, which can spread to affect humans and animals alike.”

The panel, whose report was commissioned by the British Government and the Wellcome Trust, proposed three steps to improve antibiotic use in animals.

First, they call for a 10-year target to reduce unnecessary use of the drugs in agriculture.

Second, certain types of highly critical antibiotics should be restricted.

“Too many antibiotics that are now last-line drugs for humans are being used in agriculture; action should be taken on this urgently.”

Third, there must be greater transparency among food producers on the antibiotics used to raise meat. This would enable consumers to make more informed purchase decisions.

Beyond agriculture, the panel proposed a raft of measures, including a massive public awareness campaign to raise awareness of antimicrobial resistance; improved hygiene to prevent the spread of infection; improved global surveillance of drug resistance and antimicrobial consumption in humans and animals; better diagnostics to cut unnecessary antibiotic use; promoting the development and use of vaccines and other alternatives; providing greater recognition and reward for those working in the field of infectious diseases; and better incentives for investment in developing new drugs or improving existing ones.

Veterinarians set antibiotic goal for animals

New Zealand Inc will not need antibiotics for the maintenance of animal health and wellness by 2030, says New Zealand Veterinary Association President Dr Steve Merchant.

Around 70 per cent of human infectious diseases, including meningitis, anthrax and salmonellosis (food poisoning) have come from animals.

Because levels of resistance to antibiotics are sharply increasing worldwide, Dr Merchant said, “we want animals and, by extension, humans to enter the ‘post-antibiotic’ era as safely as possible.”

This was a significant undertaking, requiring considerable teamwork and commitment from the veterinary profession, working with the medical, scientific, government and relevant primary industry sectors.

“Given the wide acceptance that the future for antibiotics is limited, and the close links between animals, humans and the environment we share, achieving this goal is essential,” Dr Merchant said.

“New Zealand is well suited to this challenge; given our size, proximity of the various specialities and relevant industry sectors, and already low use of antibiotics.”

Examples include:

* Zero use of antibiotics in aquaculture

* New Zealand is the world’s third lowest user of antibiotics on animals

* Increasing focus on animal ‘wellness’

* New Zealand’s grass-based farm management systems.

“These represent a sound platform, and veterinarians’ role at the intersection of animal life, human life and the environment makes ours a logical profession to be taking a lead,” Dr Merchant said.

“Achieving this goal will require a concerted international collaborative effort involving attitudinal and behavioural change across government, research, human health professionals, pharmaceutical companies, and a range of associated industries – as well as the public.”

Veterinarians will use and advocate for careful antibacterial management and monitoring based on responsible use of existing antibiotics, as they work with their industry partners to test and develop the necessary alternatives.

Metritis vaccine is created to protect dairy cows from common cattle disease

Cornell University scientists have developed the first vaccines that can prevent metritis, one of the most common cattle diseases. The infection not only harms animals and farmers’ profits, but also drives more systemic antibiotic use on dairy farms than any other disease.

The new vaccines prevent metritis infection of the uterus from taking hold and reduce symptoms when it does.

Metritis develops after a cow gives birth, when bacteria settle in the uterus. Infected cows suffer fever, pain, inflammation, lack of appetite, depression and reduced reproductive abilities.

The disease affects as many as 25 percent of the roughly 9 million dairy cows in the United States, costing nearly US$400 per case in lost productivity and treatment costs.

30 new vets join rural bonding scheme

Primary Industries Minister Nathan Guy has welcomed 30 new vets onto the 2013 intake of the Rural Veterinary Bonding Scheme.

“The scheme is now in its fifth year and is making real headway in tackling the rural vet shortage,” Guy said in a media statement (here).

“Since the start of the scheme in February 2009, 136 new vets have joined and the retention rate is an outstanding 96%.

“The scheme is a solid incentive, helping to make rural practices more attractive to junior vets who might otherwise end up in city clinics or heading overseas.

“Livestock farming is the engine room of New Zealand’s economy. We export around $30 billion in primary sector exports a year and we want to double that by 2025. That’s not going to happen without practically skilled, dedicated rural vets who provide animal health advice.

“These vets are now practicing in rural areas, and being supported and mentored by senior vets in their practices.”

The scheme is open to newly qualified veterinarians from Massey University who have secured jobs in rural practices working with farm animals.At the end of their third year of employment they are entitled to a $33,000 payment, and additional payments of $11,000 at the end of their fourth and fifth years.
