Today i finished the immunosuppressants chain. Its a mid-hi level chain unlocked behind blue science. To have a better yield in breeding your creatures, you may want to unlock he Assisted Embryology tech. Which will allows you to take the offspring and put in a chamber for fast development into adult. For farms, its easier and faster to produce seeds, spores or cubs than wait them to grow up to a good size for harvest. With your artificial influence, you can get more per animal (for example, an ulric have 50% of change to generate a full adult ulric after some time, the cycle of life...breed, born, grow..etc. But if you only wait for breed and birth a cub, you can force maturation in the chamber and deliver an adult Ulric in half of the time it would take to grow in the corral) since breed and birth are faster and demand less care, the changes for a cub is higher too.
But introduce foreign stuff into their tissues to accelerate the growth demands immunosuppressants, make them demands exploration of sea creatures and plants. But it worth ;) if you want a boost in your production.
