<b>Chemical composition of tree and bush species occurring in pastures of three locations in Pernambuco State</b> - DOI: 10.4025/actascianimsci.v28i1.657

Abstract

The research was conducted at the Experimental Fields of Itambé, Caruaru and Serra Talhada, owned by the Agricultural Research Company of Pernambuco (IPA). The aim was to analyze the chemical characteristics of tree and bush species grown on pasture land. In each Experimental Station, data was collected from a random sampling, during the dry and rainy seasons. Samples consisted of leaves and branches up to 5.0 cm of diameter. The average MS concentrations were 38.89, 48.27 and 55.20%. As for PB, the values observed were 15.87, 14.09 and 10.19%. The NFD and ADF concentrations were 52.37 and 37.63, 46.33 and 30.33, 50.25 and 35.07%, for Itambé, Caruaru and Serra Talhada, respectively. The studied species, independent of the region, presented better chemistry composition during the rainy season. Thus, for an adequate selection of species in silvopastoral systems, besides the evaluation of qualitative characteristics, other aspects should also be taken into consideration such as propagation, adaptation to the soil and climate conditions, animal type and objective of the animal system production.
