The number you tout is only made from a questionairre and hardly represents the full scope but yet it still showed an increase from only 3 or so cases being reported in previous studys.
Here read something a little more recent:
Sweden urged to ban animals sex after newspaper expose on bestiality -

I’ve read it. And don’t get me wrong, I don’t advocate bestiality, but the increase shown from the previous studies probably represent something else:
“In the period 2000 to 2004, 119 cases of bestiality were documented, compared to just three known cases in the 1970s, 17 in the 1980s and 70 in the 1990s.
But the author of the report, Katarina Andersson, said that the rise in documented cases did not necessarily mean that there was a de facto increase.
‘We know that there must be cases that have not been documented,’ she said, adding that people have also become more aware of the problem in recent years and are therefore more likely to report suspected cases to the authorities.”
