Crescencio Pineda and Misael Monge-Minero were charged after the group "Mercy for Animals" released video showing abuse at the Wiese Brothers Farm in Greenleaf last year.
It shows Monge-Minero abusing cows, and Pineda using machinery to hoist injured animals in the air.
These are the third and fourth convictions as a result of the investigation.
