I don't know of any books exclusively on the subject. What are you interested in exactly? A specific culture or style of casting for further knowledge or for practical application? Blood magick is a practice so perhaps look at local occult shops, book stores, or just Google search books on the topic. Blood adds power but further personalized the spell. You don't need a lot, just a few drops, and you can add blood to any spell really [though I would avoid adding it to things meant to be consumed for health reasons]
Animal sacrifices are an ancient practice many cultures did to please their gods. Today it isn't a widely observed practice and most pagans try to stay as far away from the stereotype as possible. However, there are a handful of practiced which use either animal parts or animal sacrifices, but it is rare and I know of symbolic substitutes. [Like a stuffed animal, drawing/photo or meat from a butcher] perhaps look into voodoo since they have spells calling on animal parts [bones, cow tongue, chicken feet] but please don't use magick as an excuse to kill animals. Even animal sacrifices in ancient times were treated with dignity and were used because they were the best animal in the herd to be present before the gods.
