While bird flu is worse in the winter, Gorton said it was “not going away” and was a disease the industry faces all year round.
The turkeys included in the trial could enter the food chain if they meet the quality requirements.
Gorton said birds were vaccinated to “stop them from getting ill, to prevent the need to medicate them”.
He said: “Turkeys have been chosen because they are very susceptible to disease and they are high value.
“Some of our birds ready for the Christmas market could be £100 to £150 each, so it could be a huge economic cost to us if we catch this disease and we have to have all of our birds culled.
“Just imagine the stress and the mental health it puts on farmers like myself and our colleagues in the industry when we catch this terrible disease because there’s nothing you can do about it.
“You can’t treat the birds and let them get better, this is unfortunately a one-way ticket and it is absolutely devastating for everybody.”
