I am a Veterinarian, applied for H1B in April 2015 but no response. Could there still be chances of getting it?

Is there any subject -specific or area specific quotas of H1B visas? Any idea if there is a quota for veterinarians? Nothing has been heard so far. Is there still any chance that I might have been selected in the lottery but the information is on the way?

At this point its highly unlikely.
