TRENTON - New Jersey has reportedly become the second state to approve a wildlife contraceptive for deer.

The federally developed GonaCon contraceptive works by limiting an animal's ability to produce sex hormones. However, state environmental officials say the plan is too costly and impractical.

Officials say every doe must be captured, injected, tagged and then released. Reported estimates say the program could cost as much as $1,000 dollars per deer.
