Abstract: Acute oral LD₅₀ of Diphacinone-Na to goat was 974.09mg per kg body weight. But its subacute oral LD₅₀ to goat and sheep were only 218.88mg and 155.63mg per kg body weight by oral. respectively.Its toxicity would be intensively increased if they were given by consecutive doses for 15 days. Oral LD₅₀ to goat was only 4.02mg(×15)per kg body weight and was 45 tinges biger than subacute oral LD₅₀. Therefore, during on a large scale rodenticidal management goat or sheep would be intoxicant when they picked up the poisonous baits for consecutive 15 days, and in that case they would run risk of intoxicating, otherwise they will not be in danger.
