No. Blood is not to be used to sustain the body, either medically or through food use.

Blood was to be offered back to Jehovah God per Genesis chapter 9 - by either symbolically offering it back by pouring out, or as was done in the past, offering it as/in a sacrifice.

Today we do not offer animal sacrifices, but we still do "pour out" by properly bleeding our animals for food.

Re-adding that blood back into the meat in a sausage for human consumption would not be obeying the edict to "pour out".
