Resumo: O objetivo deste trabalho foi avaliar o efeito da inclusão de feno de tifton (Cynodon dactylon) em substituição a casca de soja sobre a fermentação ruminal de caprinos alimentados com palma forrageira (Opuntia ficus-indica, Mill). Foram utilizados cinco caprinos fistulados no rúmen, alojados em baias individuais. O delineamento experimental utilizado foi quadrado latino 5 x 5 (5 dietas e 5 períodos). A dieta experimental foi composta por palma forrageira, níveis de feno de tifton substituindo a casca de soja (0; 6,25; 12,5; 18,75 e 25%), farelo de soja, uréia e sal mineral. A proporção dos ácidos graxos voláteis (AGVs) não sofreu influencia pela adição de feno a ração. Os valores de pH ruminal e a concentração de N-amoniacal (N-NH3) apresentaram comportamento linear crescente com a inclusão de feno às rações. A inclusão de feno de capim tifton em substituição a casca de soja em dietas a base de palma forrageira proporcionou aumento na concentração do N-NH3 e nos valores de pH ruminal. No entanto, reduziu a concentração dos ácidos graxos voláteis.

Abstract: The objective of this study was to investigate the Effects of substitution of soy husk by tifton hay (Cynodon dactylon) on ruminal fermentation of goats feeding with spineless cactus (Opuntia ficus-indica, Mill). Five goats rumen fistulated were used, housed in individual. The experimental design used was 5 x 5 Latin square (5 diet and 5 period). The experimental diets were composed of spineless cactus, tifiton hay (0; 6,25; 12,5; 18,75 and 25%), soy bran, soy husk, urea and mineral salt. The turnover rate of dry matter, there was no significant difference (P>0,05). However, the disappearance rate there was significant difference (P<0,05) with additional hay in the diets. The volatile fatty acids (VFA) concentration not was influenced by the addition of hay to the diet. The replacement of soy bean hull by tifton hay in spineless cactus increased ruminal ammonia-N concentration and ruminal pH, but decreased volatile fatty acids concentration MenosResumo: O objetivo deste trabalho foi avaliar o efeito da inclusão de feno de tifton (Cynodon dactylon) em substituição a casca de soja sobre a fermentação ruminal de caprinos alimentados com palma forrageira (Opuntia ficus-indica, Mill).

Abstract: Tree monocultures constitute an increasing fraction of the global tree cover and are the dominant tree- growing strategy of forest landscape restoration commitments. Their advantages to produce timber are well known, but their value for biodiversity is highly controversial and context dependent. Therefore, understanding whether, and in which conditions, they can harbor native species regeneration is crucial. Here, we conducted meta-analyses based on a global survey of the literature and on a database created with local, unpublished studies throughout Brazil to evaluate the regeneration potential of native species under tree monocultures and the way management influ-ences this regeneration. Native woody species regeneration under tree monoculturesharbors a substantial fraction of the diversity (on average 40% and 68% in the global and Brazilian surveys, respectively) and abundance (on average 25% and 60% in the global and Brazilian surveys, respectively) of regeneration observed in natural forests. Plantations with longer rotation lengths, composed of native tree species, and located adjacent to forest remnants harbor more species. Pine plantations harbor more na-tive individuals than eucalypt plantations, and the abundance of regenerating trees is higher in sites with higher mean temperatures. Species–area curves revealed that the number of woody species under pine and eucalypt plantations in Brazil is 606 and 598 species, respectively, over an aggregated sampled area of ca. 12 ha. We highlight that the understory of tree monocultures can harbor a considerable diversity of regener-ating native species at the landscape and regional scales, but this diversity strongly depends on management. Long- rotation length and favorable location are key factors for woody regeneration success under tropical tree monocultures. Therefore, tree monocultures can play a role in forest landscape restoration and conservation, but only if they are planned and managed for achieving this purpose.
