> Utilitarianism is primarily about maximizing utility of a wide spectrum of the population as it pertains to humans and societies and has nothing to do with animals, wild or domestic except for the utility they provide humanity with.

Actually, utilitarianism is about maximizing the welfare (i.e., happiness minus suffering) of all beings that can be said to have a "welfare". This goes back to the father of utilitarianism, Jeremy Bentham, who argued that any being capable of suffering deserves moral consideration. (more extensive discussion can be found in https://en.wikipedia.org/wiki/Utilitarianism) More recently, the most prominent living utilitarian philosopher is Peter Singer, who has argued extensively for the moral consideration of animals. Utilitarianism in the philosophical sense is distinct from the anthropocentric economic interpretation.
