Rape has a human victim, though. Moving away from rape is a question of human peace, collaboration and civilization. This simply isn't applicable to other species.
They are not part of humanity, even though we interact with them in some ways.
The reasonable moral concern imo is to minimize maltreatment in the industry. A lot of these problems are due to the alienation of production. We used to raise, care for and slaughter our own animals.
I don't think other species can be legally considered to have the right to life and liberty, no. I do however recognize veganism as a spiritual value.
