The effect of triorthocresyl phosphate, a delayed neurotoxin, on the testes of young broilers.
Broiler chickens were raised in brooder batteries. At 6 weeks of age 10 chickens were given either a single oral dose of triorthocresyl phosphate (TOCP) at 500 mg/kg body wt. or corn oil as a vehicle. The testes of both groups were examined morphologically and histologically. Changes in characteristics of testicular atrophy in the TOCP-treated group were clearly evident. The results also suggest that TOCP, a delayed neurotoxin, may induce sterility in young male chickens by an unknown mechanism.
