Hang on, folks, she didn't say she was "hoping" to breed them, or "trying" to breed them - she asked if we thought that was a good idea.
Whatever your interpretation of her question, I think it's a little more than disturbing that a person would give any consideration to purposely breeding a pig after one sow had given birth to a litter of dead babies and would presumably also have had a second sow give birth to pups that didn't survive (hence being the reason for the breeding).
In any case, I don't guess I see the harm in folks answering her question, which was "would it be ok to breed her purposely again?" with a resounding, "NO."
I also wanted to answer:
I am feeding daily kale, parsley and red pepper along with a blend food and timothy hay of course, do i still need to add alfalfa or is this enough?
I wouldn't feed any of these things daily, even to a pregnant sow or baby. You could feed kale one day and parsley the next, in small amounts. Change the red pepper to green (red pepper is higher in sugar).
Add a good mix of lettuce (endive, green leaf, red leaf, romaine, etc.) and try a little variety like cilantro, cucumber, zucchini, etc. There's a sticky in the Diet & Nutrition section that shows what veggies you can feed and how often that Ly made - check it out for some ideas and variety.
There's probably no need to add alfalfa since you're feeding good veggies that are high in calcium and protein, but Ly would be a better judge to answer that question. Hopefully she'll come along and answer.
I also wanted to ask - what is the "blend food" you are feeding?
