"Our daughter Megan, who works and lives on the farm, has been rearing our calves using a feed programme from Fiber Fresh for the past three spring seasons. Although it involves a bit more time and patience in the beginning, the results have proven worth it.
"They don't appear to be eating a lot to begin with, which can be worrisome and disheartening, but if their faeces appear green they are eating enough. If you persevere, they really get a taste for it after a couple of weeks."
Shane says the Fiber Fresh calves are bigger and healthier than traditionally raised calves as they do not experience the same weaning check, and then transition to the steep terrain is much easier.
In addition, last season the farm saw a record in-calf rate in heifers that were raised under the Fiber Fresh system, with 83 per cent of the heifers in calf in six weeks and 96 per cent in nine weeks.
"A fibre-based product is similar to what cows are supposed to eat - grass. After a few trials, it was a no-brainer which path to take going forward."
The Birchalls are milking 480 cows, with plans to increase the milking platform and increase numbers to 550 next season. They rear around 200 heifer calves each year - selling the surplus 60 in the autumn - and winter 140 yearlings.
"Even through the harsh 2012-2013 drought, these animals continued to work the hills - and are on target to yet again be the biggest heifers to be calved in the past 33 years.
"It costs a lot of money to raise a calf, but now that we can breed bigger, healthier young stock, with large stomachs, big through the ribs and a huge drive to eat, this has to be a huge benefit for the future of our herd."
Mr Birchall's advice to anyone interested in trialling the fibre-based programme would be to "stick at it".
He said although it can take some time to get the calves interested, it was worth the effort.
"It's an education process for both the calves and the farmers and the end product is far superior."
