Ms Haywood, who has worked as a vet for more than 10 years, said many farmers told her they disliked tube feeding.
We see a 90 per cent reduction in behavioural signs of stress in animals when we use our products.
The products, which took more than two years to develop, have a flexible tube and easy-swallow safety tip designed to flex around a calf's airway. The FlexiTuber differs from the TrustiTuber in that it has a strap to secure the calf's mouth in the optimum position.
"We see a 90 per cent reduction in behavioural signs of stress in animals when we use our products," said Ms Haywood. "Making the procedure easier on the calves also makes it easier and less unpleasant for farmers, encouraging them to treat sick or weak calves earlier."
Antahi's TrustiTuber and FlexiTuber won the Tompkins Wake IP and Commercialisation Award at last year's event, receiving $5000 in legal advice and support from top Hamilton law firm Tompkins Wake.
Ms Haywood said being involved in the Fieldays Innovation Awards was invaluable for her business, especially the support, mentoring and networking opportunities provided to entrants.
"It was the perfect place and timing to launch our products," said Ms Haywood. "The Innovations Centre is a real drawcard for Fieldays' visitors, and a lot of foot traffic comes through. It was a cost-effective way to get a sense from potential customers about the value of the products. It was a real buzz over the whole four days."
Last year 130,684 visitors attended Fieldays, making it a good opportunity for entrepreneurs to talk to future or potential customers and conduct market research.
Fieldays Innovations event manager Gail Hendricks said the Fieldays Innovation Awards has been going for more than 40 years, and the event seeks to celebrate and support New Zealand's most innovative agricultural inventions to lead change in the rural sector.
Successful applicants exhibit over four days from June 14-17 at the Fieldays.
Ms Hendricks said she was always impressed at the calibre of entrants, who typically came from a range of fields including dairy and dry stock farming, horticulture, information and communication technology, cloud and mobile-based software, animal health and genetics, water and waste management, environment and clean-tech, animal and farm management and farm safety - to name but a few.
Vodafone is partnering in the awards again this year. Sponsors include Callaghan Innovation, Crowe Horwath, Enterprise Angels, Locus Research, NZFarmer, Origin IP, Tompkins Wake and Tru-Test.
"The support we get from our sponsors is just phenomenal, and so valuable for our innovators and entrepreneurs," said Ms Hendricks.
"Award entrants have access to New Zealand's top intellectual property and commercial lawyers, business advisers, product development specialists and innovation consultants. It's pretty amazing."
The three main innovation categories are the Tru-Test Prototype (including the grassroots and established companies subcategories), Launch NZ (for innovations ready to hit the market) and International.
Other awards up for grabs include the Fieldays Young Inventor of the Year, Vodafone Innovation in Technology Award of the Year, Locus Research Innovation Award, The Crowe Horwath Agri Innovation Award, the Tompkins Wake IP and Commercialisation Award and the Origin Intellectual Property Award.
Ms Haywood said she wouldn't hesitate to recommend the Fieldays Innovation Awards to other agricultural entrepreneurs or inventors.
"We've been to other agricultural shows around the world and haven't seen anything as well set up as this. To see all the innovations and new ideas in one place, with investors and distributors and business advisors there too, it's just fantastic."
