Need help with Latin abbreviations on Galicia baptismal record

I was wondering if someone could help with a couple of Latin abbreviations that appear on my grandfather's baptismal record. This record is from a Roman Catholic parish in what was then Galicia. I have attached a cropped portion of the record where it has my grandfather's father and his father's parents listed. There is an abbreviation after their names, and I think it's an abbreviation for their occupation. Does anyone have any ideas as to what they are?

Hi Maksym!

If you want someone to read the document you should:
- give all the information you already know
- attach as big part of text as possible - it's sometimes hard to read certain words or letters, but it can be easier to do it by comparison with other parts of text

Best,
Barbara

it most probably is "agr" standing for agricultural or farmer
