Digestibility, rumen kinetics, and blood metabolites in lambs fed Samanea saman and Cordia dentata

Colombian sheep production is carried out in extensive pastures with a low percentage of protein and high fiber levels that lead to low weight gains. The aim of this study was to evaluate intake, digestibility, rumen kinetics, and blood metabolites in hair lambs fed Samanea saman and Cordia dentata. Twelve hair lambs were distributed in an experimental 4x4 Latin square design, with four treatments and four experimental periods. Treatments were T1:100 % Dichanthium spp hay, T2: 80 % Dichanthium spp hay, 20 % S. saman, T3: 80 % Dichanthium spp hay, 20 % C. dentata, T4: 80 % Dichanthium spp hay, 10 % S. saman, and 10 % C. dentata. The highest nutrients intakes were obtained with diets containing tree foliage compared with the T1 diet (p
