making sure I heard this corectly - she said that preg cows in a NEGATIVE nutrition status had calves that ultimately marbled better ??? it sure seems counterintuitive and may be hard to accomplish on the farm since we know we need POSITIVE nut. status during 3rd trimester for healthy calveing and breedback. And a natural bred herd has 2nd and 3rd at the same bunk at the same time. I'm assuming all cavles harvested were fed out uniformly. I've dramatically changed the marbeling in my English bred cavles with out changing my bloodlines, by heavy starch feeding during the month or 6 weeks after weaning - gettem fleshy and then the fat cell is easier to reactivate during the finishing process 6 months later. . hitting a negative status for that first (when nursing) or 2nd (might be doable) trimester seems like hitting a pretty quick moving target.
