[QUOTE="dcara, post: 41997, member: 473"] From a technical perspective, to estimate carrying capacity/stocking rate for a paticualr piece of property you first have to answer the question of what is the forage production rate of the property. From that you can determine how many AUs (animal units) the property will support. The higher the AU numbers the fewer the number of cattle the property can support. As I recall, 1 AU is defined as a 500lb steer or non breeding heffier gaining 1lb/day, or an 850lb steer gaining 0.25lb/day. Actually there are tables defining the whole range of AU definations for cattle. The defined AUs, for breeding stock such as bulls, pregnant cows, or wet cows are defined for maintenance weights as opposed to gains. A 1050lb bull has an AU of about 2. There used to be a web site with some good papers on this subject. I'll see if I can find it again and post a link to it. It also discussed some good appraoches for flexiable stocking rates to accomidate drought conditions. [/QUOTE]
