Definition of grazing
1 Meaning of grazingGrazing can be defined as the direct consumption of pasture for livestock in the field. It is, therefore the system more simple and cheap convert such plant material produced by photosynthesis of autotrophs (primary producers) - that in itself same has no value mens - products directly useful for it and with economic value (meat, milk, antlers, wool, work, etc.) by the performance of the pest, or secondary producers. Obviously the process causes losses of energy and other nutritious ingredients, but manages to highlight resources that previously did not. For this reason, until recent decades, grazing focused only on those plant resources: that could not be used for human consumption; which Yes had this ability (cereals, grain legumes, and others) were reserved exclusively for their use. Currently, the improvement of the economic and social situation and the increase in the demand for food products of animal origin not only allows the use of those resources for livestock feed, but it becomes habitual, with consequent loss of power posed by the consumption of secondary rather than primary producers.
Forestry experts, pastoralism is the usual system of livestock feed, both for economic reasons as for problems of collection of biomass (low unitary production, great extension, seasonality, etc.), topography and even twice the highest quality of the products obtained by grazing. However, the most frequent is the limitations of the medium (summer drought, winter cold, seasonal yields very low or zero, for example) and those of the market impose a mixed feeding regimen: animals graze in times devoid of limitations, and in critical periods they are fed on stabling or simply supplemented with resources from own pastures (often most productive periods surplus) or products or by-products of agricultural crops. In addition, it is also usual that cattle do not paste on exclusively forestry or agricultural communities: it is normal to use during certain periods of the year and for the rest, what produces a complementarity between both categories pastables resources.
2. Definition of grazingGrazing is a concept that is used to name the process and consequences of grazing. This verb, for its part, refers to move cattle to a field where he can eat grass and plants.
Who is in charge of developing the cattle grazing is called pastor. This person is in charge of caring for and guiding the animals when they are in an open area, out of stables or similar structures.
It is usual that grazing also involves a dog, which helps the pastor to control animals. There are races which, by genetic history, are equipped with the skills necessary to contribute to the pastor in this task.
It is said that grazing was one of the first steps that made the human being to be nomadic and become sedentary. To develop this technique, he began to settle in fertile land, which allowed to graze the animals then killed to feed.
Allowing the grazing is that livestock feed directly from the soil of the field. Grass is the most economical and easy to obtain, food providing the necessary energy to the animal. You have pasture available, man can be fed to livestock, which then allows you to get from meat and leather to wool, milk and other products.
Grazing, however, may be hindered for various reasons. If it develops intensively, the grass can be exhausted. On the other hand, drought and other climatic phenomena can make that it is not available for cattle pasture.
