Resumo: The objective of this study was to evaluate the effect of cutting age on the production, chemical composition, degradation kinetics and anatomy of Leucena (Leucaena leucocephala). The experimental design was a completely randomized design with a factorial arrangement 2x4 (two types of tissues and four cutting ages) for the production data of dry matter and 3x4 (three degrees of degrees of digestion of tissues and four cutting ages). Observed effect (P < 0.05) for the total production of DM of Leucena in function of different ages. The tissue types grain and non-grain showed maximum production at 70 days of age, with production of 2333,00 and 716.60 kg DM ha-1, respectively. The parameters of degradation of DM evaluated decreased significantly with the increase in the maturity of the plant, in the same way the chemical composition presented behavior inherent to the advance of age. The effective degradability DM also decreased with the increase in the rate of passage (2, 5, and 8% h-1). The highest rate of degradation (c) was obtained for 30 days. With the advance in plant maturity increases the proportion of vascular tissue lignificad influencing parameters of ruminal degradation of Leucena. The ages assessed influenced the chemical composition of the Leucena (P < 0.05), where the levels of dry matter, crude protein, acid detergent fiber and lignin and ash showed increasing linear behavior. The cutting age of 70 days offers an optimal point regarding the proportion of anatomical tissues correlated with the degradation and chemical composition of the Leucena.

Utilizou-se o delineamento inteiramente casualizado com arranjo fatorial 2x4 (dois tipos de tecidos e quatro idades de corte) para os dados de produção de matéria seca e 3x4 (três graus de digestão dos tecidos e quatro idades de corte). Verificou-se efeito (P < 0,05) para a produção total de MS da Leucena em função das diferentes idades de corte. Os tecidos tipos forrageiros e não forrageiros apresentaram produção máxima aos 70 dias de idade, com produção de 2333,00 e 716,60 kg de MS ha-1, respectivamente. Os parâmetros de degradação da MS avaliadas diminuíram significamente com o aumento na maturidade da planta, da mesma forma a composição química apresentou comportamento inerente ao avançar da idade. A degradabilidade efetiva da MS também diminuíram com o aumento na taxa de passagem (2, 5 e 8% h-1). A maior taxa de degradação (c) foi obtida aos 30 dias. Com o avanço na maturidade da planta aumenta a proporção de tecido vascular lignificado influenciando nos parâmetros de degradação ruminal da Leucena. As idades avaliadas influenciaram a composição química da Leucena (P < 0,05), onde os teores de matéria seca, proteína bruta, fibra em detergente ácido e Lignina e cinzas apresentaram comportamento linear crescente. A idade de corte de 70 dias apresenta um ponto ótimo quanto à proporção de tecidos anatômicos correlacionados com a degradação e composição química da Leucena.UEL2019-09-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3265010.5433/1679-0359.2019v40n6Supl2p3133Semina: Ciências Agrárias; Vol. 40 No. 6Supl2 (2019); 3133-3142Semina: Ciências Agrárias; v. 40 n. 6Supl2 (2019); 3133-31421679-03591676-546Xreponame:Semina.
