three ideas

1) bring out psychological attributes that are associated with the gig you are trying to land.

- talk in past tense of things like responsibility, dependability, punctuality, patience. outline to the interviewer and in the cover letter, that youre exoerience is just the sort that they need. if you worked with livestock, then you obviously have tons of experience working in high-stress, high-workload environment and that you can be relied on with equipment and inventory worth millions of dollars.

2) you might consider that as obvious, but you can count as work experience volunteer work. especialky if you can get a reference.

3) you might need to get a low-end gig for the time being. make sure at least it would be something to put on a c.v later. tons of online gigs, like content writing, teaching, editorial, sales, translation...pay is nor amazing but you add things up...
