Goal: Science & Love.
>I intend to write a series of papers and books designed to help promote ethical farming methods while improving production and quality of life for both the livestock and the farmer.
Income: Milking & Breeding.
>The milking is intended as the primary source of revenue. Rather than selling her calves though the goal here would be to find the ideal way to raise them for long, healthy, happy lives as productive (and cute) milkers.
Age: Yearling.
>The perfect time to start her off to maximise both milk production and birth rate.
Origin: Europe.
>Not amazingly relevant, but I'll stick with what I know.
Skin Colour: Pale.
>For maximum cuteness, and because I'll be carefully managing her time outside of an indoors environment specially designed to promote her health, productivity, happiness, fertility, and attachment to her owner.
Hair Colour/Style: Blonde, pigtails.
>We're already maximising cuteness here.
Personality: Ditzy & Cheerful.
>I'd be very surprised if she didn't at least turn out to be heavily submissive, but I'm not looking for a masochist here.
Acquisition: Free Will.
>For the first generation at least her desire to become the best cow she can be would be important.
Living Quarters: With me.
>Do I want to get attached? Absolutely. Do I want her to get attached? Absolutely. Do I want the most convenient set up for monitoring and controlling her life? Very absolutely.
Outfit: Nude.
>She doesn't need, benefit from, or deserve privacy. This will help her get accustomed to that new reality.
Accessories: Cowbell collar (permanent), ball gag (as needed)
>Muting her with the gag will help her get used to life as an owned piece of livestock (even though she wants that life it will still be a hard step for her at first) and for cuteness. The collar acts a constant reminder of her new place and (once her training has sunk in) how much she loves it, and her owner.
Breast Hormones: Large Does (as close to overdose as possible without compromising her mobility - cumbersome is good, immobile presents problems).
>This should help maximise her milk production, looks fantastic on her, and should promote a slower pace of movement without leading to atrophy of her everything that would come from permanent lack of movement.
Transformative Drugs: Udder Growth & Extra breasts
>See above.
Surgery: Septum Piercing & Ear Tag
>The tag will help with record keeping once the herd starts to grow (say by the 3rd generation), and the septum piercing will serve as a useful place to attach a leash when she's being walked outside.
Punishments: Reprimand, Spanking, Isolation
>In that order for more and more serious infractions.
Rewards: Praise, Affection, Food.
>Praise and affection would be almost continuous while she's behaving well. As there's no option for improving her fertility in the options given so far the food would be dosed with the appropriate drugs.
