1034 watched as Mother went through her usual morning rounds, inspecting the health and output of each boy, eagerly awaiting his turn. He was still feeling jealous from watching the maintenance man have his way with the new boy across the aisle, and hoped beyond hope that Mother would be giving him special love and attention. He had already been milked twice today, but that did little to calm him down, and he idly tried to hump into his milker.
"Ah, 103...4," Mother said to herself, stepping up to the screen in front of his stall. "Increased your rate to 12 a day, yeah... hm."
She moved to his side, and then gave his balls an experimental light squeeze. "Plenty full in here, and already milked a couple of times today..." She gently rolled his testicles a bit more in her hand for a few seconds longer, before stepping back.
"Looking good, I'll be around with the biologist for observation for the last few milkings, see if those testicles hold up..." she spoke, mostly to herself.
An alarm rang through the barn, and 1034 was suddenly distracted by the sensation of a jet of cold water rushing up his ass, while simultaneously a tasty thick liquid flooded his mouth from the feeder, which he eagerly swallowed down.
"You boys sure do love breakfast," Mother chuckled to herself, before walking off to the next stall.

It was thirteen hours later and 1034 was tired, and was dozing in and out of sleep. He had been milked plenty, and was sure his work for the day was over. His cock was only half hard now in the milker, an unusual state for him.
He was jolted awake from dreaming of breeding an ample young woman in a green pasture by the click of heels down the center aisle of the barn.
"Here he is, 1034. Only the second of our stock to be moved to 12 a day, still has... " Mother looked for a second at the screen, "two more milkings for today. As you know Dr. Ammon, the first livestock we moved to twelve was overworked quickly, and corporate wants you to figure out a hormone mix for the boys to prevent that reoccurring. This lucky boy here will be our guinea pig."
The woman Mother was talking to nodded and looked up from her pad at 1034. She was wearing a white labcoat, was shorter and younger than Mother, thinner and blonde. 1034 vaguely remembered her poking and prodding him from his early days here, but his memory beyond the last few months was hazy. In fact, he realized, he could not remember his name... or had he always been 1034?
"I've been working on a compound that should not only help sustained semen production and arousal, but increase docility. I will provide the stock with a first dose now, the rest should be included daily in its liquid meals in the future," the doctor responded.
She walked up to 1034 and pulled out his feeder. He sputtered briefly, and then she shoved a gloved hand into his mouth. "Take it, swallow now," she commanded forcefully, spurting a liquid into his throat with a syringe and then shutting his mouth tight. He gulped down the gross tasting medicine, and she looked satisfied. She rather roughly shoved the feeder back into his mouth.
