There is an article about Evaluation of Sodium Nitrite for mass euthanasia of commercial pigs:
Of the feed treatment groups, 53 of 80 pigs (66%) were euthanized by SN. Each feed treatment resulted in a range of 50-80% mortality regardless of treatment. 63% of the pigs vomited during the feed treatment. Pigs on averaged consumed 0.49 g of SN per kg of body weight with a range of 0.20 to 1.09 g of SN per kg.
General timeline of clinical signs:
•0-45 minutes: good feed intake
•45-75 minutes: stop eating and huddle
•75 minutes: start to observe vomiting. Progresses to ataxia and palor and then lateral recumbency.
•90 minutes: earliest mortality. Most were 90-180 minutes.

it looks like Russian roulette, only 50 to 80 percent chances of dying
