Rising Ulster Rugby player Nevin Spence died on Saturday along with his brother Graham and his father Noel in a slurry tank accident at the farm in Hillsborough, County Down.
The 22-year-old, who at represented Ulster 42 times, mainly at centre, was tipped as a future Ireland international.
A range of rugby, other sports and political figures have expressed their shock at the deaths.
Peter Robinson, Northern Ireland first minister and Martin McGuinness, deputy first minister
"It was with great sadness that we learned of the sudden and tragic passing of Noel Spence and his sons Nevin and Graham in an accident on their family farm yesterday.
"This tragedy has shocked the entire community and is a terrible reminder to us all of the dangers of farming life. Our thoughts are also with farmers everywhere at this time.
"Our thoughts and prayers are with the Spence family at this extremely sad time and pass on our deepest condolences to them. We understand another member of the family, Emma, has been hospitalised following the accident and we wish her a full and speedy recovery.
"Nevin was a rising star of local rugby and it is only a matter of months ago, in happier times, that we had the honour of hosting him and his colleagues at a reception in Parliament Buildings to celebrate the achievement of Ulster in reaching the Heineken Cup final.
"His untimely death is a blow for the game in the province and we sympathise with his teammates and everyone at Ulster Rugby who have lost a true colleague and friend."
Edwin Poots, health minister
"While a lot of people may focus on Nevin because he played for the Ulster rugby team we do need to focus on Noel and Graham at this time.
"Noel has left a wife and two daughters, Graham a wife and two children. Whilst a place in a rugby team can be filled a place in the home of all three men will never be filled."
Brian O'Driscoll, Ireland rugby captain
"Devastating news about Nevin Spence, his dad and brother.
"What a wonderful talent he was. Thoughts and prayers go out to his family and friends."
John Dickson, Ballynahinch Rugby Club
"I was with him (Nevin) two weeks ago doing a photoshoot at the farm, to promote the Milk It web page for the Dairy Council, and we kept his brother Graham waiting for half an hour.
"Graham was keeping Nevin going that he was a gentleman farmer, who never kept time.
"I just can't contemplate how anybody could cope with this."
Theresa Villiers, Secretary of State
"I am deeply saddened by this tragedy. It will be devastating for the family and friends of those who have lost their lives and a cause of great sadness for the whole community. This loss will be particularly strongly felt across farming and sporting circles.

Basil McCrea, Ulster Unionist assembly member
"The entire community, whether it is the rugby fraternity, or the farming community, or just the wider local community, people have such empathy with the family.
"They just don't know what to do or what to say."
