[QUOTE="regolith, post: 849073, member: 9267"] I did post my measures of assessing the starting weight: weigh tape round heart girth on that large Friesian cow, and another xbred that went recently but I don't recall what her slaughter weights were, I know none of that particular group were anywhere near the 580 kg I'd 'weighed' her at. And giving those heifers a quizzical look because the smallest of my Jerseys are weighed around 1 May each year at 350, the larger ones closer to 400. An extra condition score + calf might account for 10 % of that weight, meaning skinny heifer without calf would be closer to 300. Mature cow standing next to heifer (the sort that is weighed less than 300 at the works) is much taller and bulkier. They develop a lot of capacity up to four or five years old. And then there's standard weights used in the industry for those breeds - and my cows are not small examples of the breed. I've heard it said that cows can lose a full conditon score owing to dehydration after a long truck journey - but I have watched my cows leave trucks after five or six hour journeys, and they look as fit as they did when they got on. Anyway, inbredredneck thinks 34% weight loss is quite within the realms of possibility. I'd like to know why - maybe my cows really are 30% rumen? [/QUOTE]
