<b>Production and nutrition rates of piatã grass and hybrid sorghum at different cutting ages</b> - doi: 10.4025/actascianimsci.v35i3.18016

Abstract:

The influence of cutting age on yield and nutrition rates of piatã grass (Brachiaria brizantha cv. BRS Piatã) and hybrid sorghum (Sorghum spp. cv. BRS 801) under an integrated crop-livestock system was evaluated. The trial was carried out at the Embrapa Beef Cattle (20°27¢ S; 54°37¢ W) in Campo Grande, Mato Grosso do Sul State, Brazil, between April and October 2009. Experimental design consisted of randomized blocks with four replicates. Treatments were distributed across a split-plot des… Show more

“…This result is different from that reported by Moreira et al (2013) for the differences observed in the in vitro digestibility of the dry matter (IVDDM) of different Brachiaria varieties and grazing systems. Similarly, Quintino et al (2013) found that the age of the plant affected the IVDDM of B. brizantha cv. BRS and B. brizantha.…”

“…Los resultados obtenidos pueden ser atribuidos a las características bromatológicas observadas en cada pastura, ya que la edad de cosecha utilizada (cuarenta días) pudo influir en la calidad del forraje. Quintino et al (2013) encontraron que la edad de la planta afectó significativamente la digestibilidad in vitro de B. brizantha. Está bien documentado el efecto negativo de aportes deficientes de nitrógeno en la dinámica ruminal (Minson, 1990), así como también, la restricción que imponen altas concentraciones de fibra en la digestibilidad de la dieta (Van Soest, 1994).…”

“…Os teores de P, tanto no pré como no pós-pastejo não foram alterados pela altura de manejo do pastejo intermitente, mas os teores de N e K foram reduzidos com a elevação da altura dos pastos (Tabela 3). Esse comportamento nos teores N ao longo da rebrotação do capim tropical já foram observados na literatura (Quintino et al, 2013e Paula et al, 2012. Pelo menos em parte, essa resposta está relacionada com a mobilidade do nutriente na planta, pela variação na demanda do nutriente ao longo do período de rebrotação associado a um mecanismo de diluição do N e K com a maior produção de biomassa e, por fim, pela instabilidade do nutriente na solução do solo.…”
