Abstract – The objective of this work was to determine the nutritional content
and the degradability of the dry matter and protein of fruits of Chloroleucon
mangense and Acacia cochliacantha and of a 1:1 mixture of both, offered as
supplements to Rambouillet sheep. In situ ruminal degradation was evaluated
in three adult rams, fitted with a rumen cannula, with different incubation
times of 0, 6, 12, 24, 48, and 72 hours. Protein intestinal degradability was
quantified with a three-step procedure: in situ ruminal incubation, in vitro
enzymatic digestion, and abomasal-intestinal digestion. The fruits of C.
mangense and A. cochliacantha contain 21 and 12% crude protein, 47 and
56% neutral detergent fiber, 31 and 43% acid detergent fiber, and 0.9 and 6.0%
condensed tannins, respectively. The fruits of C. mangense showed a higher
nutritional value and a higher dry matter and crude protein degradability
(p&lt;0.05) than those of A. cochliacantha and the 1:1 mixture. The amount
of protein that reaches the small intestine is higher for the 1:1, which is an
indicative that its tannin concentration is enough to increase the bypass
protein that can be absorbed in the small intestine.

Resumo – O objetivo deste trabalho foi determinar o conteúdo nutricional
e a degradabilidade da matéria seca e da proteína de frutos de Cloroleucon
mangense e Acacia cochliacantha e de uma mistura 1:1 de ambos, oferecidos
como suplementos para carneiros Rambouillet. Foi avaliada a degradação
ruminal in situ em três carneiros adultos, com colocação de uma cânula
ruminal, com diferentes tempos de incubação de 0, 6, 12, 24, 48 e 72 horas. A
degradação intestinal da proteína foi quantificada por meio de procedimento
com três etapas: incubação ruminal in situ, digestão enzimática in vitro e
digestão abomasal intestinal. Os frutos de C. mangense e A. cochliacantha
contêm 21% e 12% de proteína bruta, 47% e 56% de fibra em detergente neutro,
31 e 43% de fibra em detergente ácido e 0,9 e 6,0% de taninos condensados,
respectivamente. Os frutos de C. mangense apresentaram valor nutricional
edegradabilidade da matéria seca e da proteína bruta (p&lt;0,05) maiores que
os de A. cochliacantha e da mistura 1:1. A quantidade de proteína que chega
ao intestino delgado é maior para a mistura 1:1, o que é indicativo de que sua
concentração de tanino é suficiente para aumentar a proteína não degradável
no rúmen absorvida no intestino delgado.
