Abstract

The aim of the present research was to determine the forage quality of grassland in a silvopastoral system of the Delta of the Paraná river, Argentina. For this research, there was conducted a census that showed the dominance of the species Carex riparia check for this species in other resources , Cyperus check for this species in other resources spp., Scirpus giganteus check for this species in other resources , Scirpus californicus check for this species in other resources y Polygonum check for this species in other resources spp. Other species were present in lower proportion, Panicum pernambucensis check for this species in other resources , Panicum elephantipes check for this species in other resources , Paspalum urvillei check for this species in other resources ; Lolium multiflorum check for this species in other resources , Phalaris angusta check for this species in other resources , Glyceria multiflora check for this species in other resources , Leersia hexandra check for this species in other resources , Echinochloa check for this species in other resources sp. y Alternanthera filoxeroides check for this species in other resources . Cuts and determination of nutritional value of the samples were made. The results showed the following values: for dry matter 36.6%, crude protein 9.24%, neutral detergent fiber 67.9%, and acid detergent fiber (ADF) 40.6%. Digestibility estimated based on the ADF resulted in an average of 57.3%. Values of total polyphenols were relatively low, ranging between 2.77 and 0.83%, being the average 1.99%.

 es Determinación de la Calidad Forrajera en un Pastizal Natural de la Región Del Delta Bonaerense Argentino
González, Gabriela L.; Rossi, Carlos A.; Pereyra, Ana M.; De Magistris, Alberto A.; Lacarra, Héctor R. & Varela, Eugenio A.

Resumen

El objetivo del presente trabajo fue determinar la calidad forrajera de un pastizal natural en un sistema silvopastoril del Delta del Paraná, Argentina. Para este trabajo se realizaron en primer lugar censos de vegetación que demostraron la dominancia de las especies Carex riparia check for this species in other resources , Cyperus check for this species in other resources spp., Scirpus giganteus check for this species in other resources , Scirpus californicus check for this species in other resources y Polygonum check for this species in other resources spp. Otras especies presentes en menor proporción fueron Panicum pernambucensis check for this species in other resources , Panicum elephantipes check for this species in other resources , Paspalum urvillei check for this species in other resources , Lolium multiflorum check for this species in other resources , Phalaris angusta check for this species in other resources , Glyceria multiflora check for this species in other resources , Leersia hexandra check for this species in other resources , Echinochloa check for this species in other resources sp. y Alternanthera filoxeroides check for this species in other resources . Posteriormente, se realizaron cortes y análisis de valor nutritivo de las muestras. Los resultados mostraron los siguientes valores para materia seca 36,6%, proteína bruta 9,24%, fibra de detergente neutro 67,9% y fibra de detergente ácido (FDA) 40,6%. La digestibilidad estimada en base al FDA resultó en un promedio de 57,3%. Los valores de polifenoles totales fueron relativamente bajos, oscilando entre 2,77 y 0,83%, siendo el promedio 1,99%.
