Relating to the regulation of deer breeding by the Parks and Wildlife Department.

HB 3607 requires deer breeding facilities in Texas to maintain fences at least eight feet high to contain breeder deer. It directly affects businesses holding deer breeder permits under Texas Parks and Wildlife Code, specifically those managing white-tailed or mule deer for propagation. Key provisions include amending fence height requirements from seven to eight feet for both breeding facilities and release sites, and clarifying that "breeder deer" refers to deer legally held under this subchapter. The bill updates existing regulations to standardize containment measures for these operations.
