Well, blood IS a hard look to get straight out of Maya without any plugins, I agree.
You could try reading the docs regarding the "Blobby" particle render type, as it cam be mapped with a shader like a Blinn with a medium-high specularity, and high essentricity.
Keep your reflections in check, as Human blood looses & blurs reflection as it dries.
For the animation, depending on how goopy, or fluid (splashy) you want your blood to be, try using more than one emitter to give you a variety of blob sizes, or just use a creation expression from our dynamics Expressions thread to give you a number of random blob sizes with one emitter
Also, which shot were you going for?
The "chopping-off-heads" style of blood shooting, or something less?
