The Craftable Animals mod allows you to craft all the available mobs plus it has an add-on for the Mo’creatures mod that allows you to craft those mobs as well.

Once you create the “Animal Bow” and have the desired crafted animal in your inventory then it’s just a matter of shooting the bow in your farm or anywhere else really…

…and voila, instant animal.

There’s even a minimizer tool that will allow you to shrink or re-grow your animals. And you can even fill empty Spawner cubes with an animal of your choice.
