A simple spreadsheet could now create a graph for the farmer to allow informed decisions to be made, particularly about the grazing interval or rotation length. [17] By rotational grazing, a “feed wedge” is built up ahead of the stock, and it’s easy to see which paddocks are growing the most feed and can be grazed next.
Developing a grazing management plan plays an important role in the sustainability and productivity of livestock operations.
Managed rotational grazing is a key component of a regenerative agriculture system, as it functions as a constant feedback loop. [7] Rotational grazing has been said to be more environmentally friendly in certain cases. Many pastures undergoing certain types of rotational grazing are less susceptible to soil erosion. Paddocks might require ...
Animal unit months (AUMs) in a grazing area (calculated by multiplying the number of animal units by the number of months of grazing) provide a useful indicator of the amount of forage consumed. On public lands in various jurisdictions, authorized use of forage for grazing is commonly expressed in animal unit months.
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 ...
Dairy cattle grazing in Germany. In agriculture, grazing is a method of animal husbandry whereby domestic livestock are allowed outdoors to free range (roam around) and consume wild vegetations in order to convert the otherwise indigestible (by human gut) cellulose within grass and other forages into meat, milk, wool and other animal products, often on land that is unsuitable for arable farming.
Holistic planned grazing is similar to rotational grazing but differs in that it more explicitly recognizes and provides a framework for adapting to the four basic ecosystem processes: the water cycle, [6] [7] the mineral cycle including the carbon cycle, [8] [9] energy flow, and community dynamics (the relationship between organisms in an ...
In an economically optimum forest rotation analysis, the decision regarding optimum rotation age is undertake by calculating the maximum net present value. It can be shown as follows: NPV and its relationship with rotation age and revenue. Revenue (R) = Volume × Price; Cost (C) = Cost of harvesting + handling. Hence, Profit = Revenue − Cost.
