Not a nice place...but sadly there will be places similiar to this all over the world.
A few years ago a lady I knows involved with rabbit and guinea pig rescue took some guinea pigs in from a university laboratory. If I remember rightly, they were all male guineas and white.
Thankfully they had not been physically harmed (or did not appear to be) and were well handled and in good condition. Though no doubt very pleased to be released into rescue and placed in loving homes.
Unfortunately the majority of guineas who leave this farm (and places like it) will suffer a much worse fate...never knowing the love and security of a caring home. All they will know is, fear, pain and an early death.
The tragic thing is, the experiments carried out on these little animals are considered non conclusive and a waste of time by many scientists.
Such a waste of life.
