Livestock grazing comparison is a method of comparing the numbers and density of livestock grazing in agriculture. Various units of measurement are used, usually based on the grazing equivalent of one adult cow, or in some areas on that of one sheep. Many different schemes exist, giving various values to the grazing effect of different types of ...
A pasture wedge graph or feed wedge is a farm management tool used by dairy farmers for the purposes of managing pasture. [1] [2] [3] It takes the form of a bar graph, [4] that shows the amount of feed available in a pasture over time, and is therefore shaped as a declining wedge.
Range Condition Scoring was developed as a way to quantify biodiversity in a given rangeland system. This practice is widely used in the Sand Hills region of Nebraska, as well as the tallgrass prairie regions, as evidenced by the authoritative book on the subject, "Range Judging Handbook and Contest Guide for Nebraska."
This simple method is sometimes used for cattle. The number of animal units represented by one or more head of cattle may be calculated by dividing their total body mass in kg by 454 (or dividing their weight in pounds by 1000). Thus an 800-pound steer would be considered equivalent to 0.8 animal units. [4] Estimation based on metabolic body size.
Various formulas are used for calculating grazing fees on public lands. Some examples are: For federal rangelands of the United States, the grazing fee "equals the $1.23 base established by the 1966 Western Livestock Grazing Survey multiplied by the result of the Forage Value Index (a derived index of the relative change in the previous year's average monthly rate per head for pasturing cattle ...
When it comes to sustainable livestock production and agriculture, measurement is the first -- and sometimes most elusive -- step in the process of turning our food system from a carbon emitter ...
When stocking, a tree's basal area is measured. The basal area is a cross-sectional area of the stump taken about 4.5 feet (1.4 m) above the ground. [7] The equation for calculating the basal area of trees in a stand is Basal Area = 0.005454 DBH 2, where DBH is the diameter of the tree at the aforementioned measuring height. [7]
A more modern European system is Großvieheinheit (GV or GVE), corresponding to 500 kg in liveweight of cattle. In extensive agriculture 2 GV/ha is a common stocking rate, in intensive agriculture, when grazing is supplemented with extra fodder, rates can be 5 to 10 GV/ha.
