Nutritive value of processed feed resources from natural pastures within South-West, Nigeria

The nutritive value of forage resources from natural grazing land as dry season feed supplements for grazing animals were evaluated through their chemical composition and in vitro gas production. The forage resources include conserved forages (hay and silage), browse plant (Leucaena leucocephala lea...

Summary:The nutritive value of forage resources from natural grazing land as dry season feed supplements for grazing animals were evaluated through their chemical composition and in vitro gas production. The forage resources include conserved forages (hay and silage), browse plant (Leucaena leucocephala leaves) and the forages in the natural pasture during the dry season served as the control. Crude protein (CP) contents of the forage resources ranged from 59 to 171 g/kg dry matter (DM), with L. leucocephala leaves having the highest (p< 0.05) CP contents. Neutral detergent fibre (NDF) and acid detergent fibre (ADF) contents of the forage resources ranged from 560 to 705 g/kg DM and 363 to 440 g/kg DM, respectively. The highest in vitro gas production of 38.7 ml/200mg DM was recorded for L. leucocephala leaves which was followed by silage and hay while forages in the natural pasture during the dry season recorded the least gas production. The volume of gas production significantly (p El valor nutritivo de recursos forrajeros de pastos naturales alimenticios en la estación seca para los animales en pastoreo fueron evaluados a partir de su composición química y producción de gas in vitro. Los recursos forrajeros incluyen forrajes conservados (henos y ensilado), planta arbustiva (hojas de Leucaena leucocephala) utilizando como control los forrajes del pasto natural durante la estación seca. El contenido de proteína bruta (CP) de los recursos forrajeros osciló de 59 a 171 g/k-l de materia seca (DM), siendo las hojas de L. leucocephala las que presentaron el mayor (p
