In 2010, Ohio passed regulations banning the use of veal crates and gestation crates. The prohibition on the use of veal crates has been in effect since 2018, and the rules concerning gestation crates will go into effect on December 31, 2025. Ohio has also banned the use of battery cages for newly constructed farms.

Section 901:12 of the Ohio Administrative Code provides more information on the bans. 

Veal housing must “allow for quality air circulation, permit opportunity for socialization between veal calves, with consideration given to ensuring the calf's health is maintained, allow the calves to stand without impediment, provide for normal resting postures, groom, eat, lie down and rest” and “the calf must be able to turn around… and veal calves must be housed in group pens by ten weeks of age.”

As for breeding sows, the Ohio law requires that by 2026, “breeding/gestation stalls can only be used post weaning for a period of time that seeks to maximize embryonic welfare and allows for the confirmation of pregnancy”

For hens, the law states that “Conventional battery cages systems may not be installed, after the effective date of the rule, on any farm not defined as an existing farm.” This means new farms raising hens in the state of Ohio must ensure that housing facilities adhere to cage-free standards. Furthermore, if an existing farm is already using a battery cage system, it must provide for a minimum of sixty-seven square inches per hen.  A violation of this law is divided into minor and major violations. Minor violations are unintentional acts and can result in a fine up to $500 for the first offense. Major violations can result in a fine up to $5000 dollars and depending on the severity of the violation, may include assistance from other parties to care for the animals.
