Why we Farm Cows and not Goats
The reason why we farm cows and not goats for dairy products is quite simple. Cows are easy to control and can live on just grass, they are grazers. Goats are browsers and are very difficult to fence in.
However that does not mean that it should stay that way.
Modern dairy cows live an average of just under three lactations, about 6 years. Yet these animals can easily have a stress free lifespan of 12 to 15 or more years.
