Energy balance and nitrogen in cattle to the region Carrizal-Chone silvopastoral systems.

Abstract:

Today it is important to make estimations and calculations of different indicators of sustainability in livestock systems that consider all the components, which are related to the use of sources of energy, and nitrogen for the execution of the present production flows and outputs of these elements in the system products. This work was carried out with the objective of determining the influence of Silvopastoral Systems livestock using nitrogen and energy balances, data were used directly in units, which has a total area of 24 hectares, 102 cattle hybrids of Holstein-Zebu, Brown Swiss-Zebu, Gyrolando Sahiwal and Jersey. Grass species that predominate are Savoy (Panicum maximum, Jacq) and cv African Star (Cynodon nlemfuensis, Vanderyst) and other species such as Tejano grass (Paspalum notatum, flügge). Among the native creeping legumes dominated by species of the genera Centrosema, Desmodium, Macroptilium, and Teramnuz. Shrubs and forage resources include Prosopis juliflora, Gliricidia sepium, Guazuma ulmifolia, Leucaena leucocephala. The investigation was not experimental, because it is an evaluation based on productive and reproductive records of livestock of the system. It is concluded that the balance of nitrogen from the unit were positive, since the amount of nitrogen that joined the system was higher (86.01 kg of N 2/ha/year) while outputs were lower (32.47 kg of N 2/ha/yr), was also obtained good results in terms of energy balance getting an efficiency of 0.67%.
