Animal right to start with should be look at from creation point of view. Their been created was there a purpose for it? Animals or Humans who  was given the authority to dominate and rule over all creations by God? So by answering these questions  we will see that God created everything that man needed to live and use as a source of meat, security. Transportation, sports, Agriculture,Sacrifice....etc God made man for the purpose of Dominating and ruling over all that God created, including all animals. i did not see where God gave the animals Right, in any form, in fact when man sin against God,it was an animal  that God killed and use the skin to cover Adams and Eve's nakedness. God also require in the old testament the blood of an animals and the animals for  for sacrifices,so i did not see where the animal rights are stated or mentioned.
