> dunmovin farms Thank you. I understand your point. I've been told another reference after MGA withdraw is "silent heat". My question is feeding MGA to feedlot cattle for a prolong period detrimental. I start feeding them MGS around 550lbs and pull the Heifers out for breeding @950lbs. My concern is withholding them from cycling that long might effect Fertility down the road. Thank you for any help!
