Identificação botânica, descrição morfológica e composição bromatológica do capim paulistão cultivado em vazante no município de Paulista-PB.

Abstract

This study aims to identify botanically Paulistão the grass grown in areas of ebb in the backlands of Paraiba region as well as their morphological description and assess chemical composition , in order to gain greater knowledge of these characteristics to help the creators of the semiarid region improve the conditions of animal feed in the dry season . The material was analyzed in the laboratories of Animal Nutrition and Physical Chemistry Analysis of CVT Federal University of Campina Grande , belonging to the Center for Science and Technology Agrifood Campus of Pombal -PB . The forage was in place Collected Souls in the municipality of Paulista - CP, located 27 km from the city of Pombal -PB . The samples were placed in glass jars with the absence of oxygen for chemical analysis according to the methodology of the Instituto Adolfo Lutz (2008 ) . The grass Paulistão grown in areas of ebb in the backlands of Paraiba region it is a grass Brachiaria sp . It is noted that in relation to plant height and weight , the samples had higher mean with increased interval between cuts, from 0.99 meters, 1.68 meters 3.83 kg to 12.16 kg and 30 and 60 days of cultivation , respectively. Checking up losses in forage quality with intervals between cuts at 60 days . The average values for MS ranged from 17.41 % to 23.51 % EE 1.94% to 3.63% , CP ranged from 10.09 % to 13.67% , 8.86 % and MM 15.77% MO and ranged from 91.14 % to 84.23 % respectively. The results show that the grass Paulistão Brachiaria spp. can be provided to the animals until 60 days after planting without any significant losses in the chemical composition of the forage , with increase in biomass production with no loss of food quality.
