In high school, 2nd poultry farm I worked at, farmer also raised pigs. I saw a regular large domestic boar in the pen jump a 6 foot fence during castration time. He was determined not to lose his manhood.
Here, Hogdini being smaller scaled the fence using the trap door at a slant to prop him. In my case, I saw this large bore jump it clearly, no scaling. I gained a different perspective on pigs after that.
