Degradabilidade ruminal da matéria seca e da proteína bruta de folhas e folíolos de forrageiras tropicais

Abstract: RESUMO -Foram determinadas as degradabilidades in situ da MS e PB dos folíolos de três leguminosas tropicais -leucena (Leucaena leucocephala (Lam.) de Wit), guandu (Cajanus cajan (L.) Millsp.) e soja perene (Neonotonia wightii) -e de folhas de outras duas forrageiras tropicais -rami (Boehmeria nivea (L.) Gaudich) e mandioca (Manihot esculenta Crantz). Amostras de 3 g (guandu, soja e rami) ou 5 g (leucena e mandioca) do material foram incubadas no rúmen de quatro novilhos por períodos de 3, 6, 12, 18, 24 e 48 h… Show more

“…According to Malafaia et al (1997), crude protein can be fractionated to better characterize, with fraction B 3, the insoluble protein in neutral detergent, and Ribeiro et al (2001), suggested lower digestion rates of fraction B 3 . Veloso et al (2006) observed that pigeon pea presented a lower ruminal degradation with insoluble nitrogen content in acid detergent of 26.2% from total nitrogen, with negative correlation associated to insoluble acid detergent nitrogen levels, and with degradation components from fiber fraction. Pigeon pea presented lower degradation and crude protein degradation rate compared to other legumes, even with higher protein content.…”

“…According to Veloso et al (2006), bush legumes, such as pigeon pea, present higher proportions of antinutritional substances in their composition. Thus,the tannin and lignin (Van Soest, 1994;Broderick, 1995;Veloso et al, 2006) probably reduced the dry matter degradation that reached 49.8% in 48 hours of incubation.…”

“…Evangelista et al (2002) studied the in situ degradability of 15 alfalfa cultivars, and found similar mean values for fraction B (38.0 to 44.4%) and higher for kd rate (0.078 to 0.124/h) and potential degradation (78.4 to 81.6%). Veloso et al (2006) Sá et al (2011) for Brachiaria brizantha (12.9 to 14.6 h), with ages ranging from 28 to 54 days, and by Campos et al (2000) for corn silage (6.2 to 9.1 h) in a period of 48 hours. The fiber fraction is directly related to most of the events involved in this parameter.…”

“…Cabral Tabela 4 -Degradabilidade potencial (DP) e efetiva (DE) da matéria seca (MS), da proteína bruta (PB) e da fibra em detergente neutro (FDN Não houve grandes variações na degradabilidade efetiva da PB das silagens em cada taxa de passagem. Resultados semelhantes foram observados por Veloso et al (2006), que verificaram degradabilidade efetiva de 60% da PB em folíolos de leucena a uma taxa de passagem de 5%/ hora. Sarti et al (2005) também observaram valores de degradabilidade efetiva da PB de 66,8; 58,2 e 54,3%, respectivamente, em silagens de capim-elefante nas taxas de passagem de 2, 5 e 8%/hora.…”
