ABSTRACT.- Questions: Degradation of facilitative interactions of native species can play an important role in the establishment and expansion of invasive plants in communities. We evaluated the relationship between the level of invasion of Cynodon dactylon and the arbuscular mycorrhizal colonization of the native Paspalum notatum in Uruguayan grasslands, which were either extensively managed (natural vegetation [NG]) or oversown with exotic legumes and fertilized with phosphorus (NG + LP). Specifically, we investigated whether increasing invasion levels were associated with reductions in P. notatum mycorrhizal colonization, growth, and nutrient content.

Abstract: Diets combining herbage and total mixed rations (TMR) are increasingly used in temperate regions for feeding ruminants,
but little information is available regarding the effects on nutrient intake and digestion of this feeding management in beef cattle.
The aim of this study was to determine the effects of combining TMR (10% CP and 13% ADF), and legume-based herbage
(14% CP and 27% ADF) on intake, nutrient digestion, ruminal fermentation, microbial N flow and glucose and nitrogen
metabolism in heifers. The experiment was a 3 × 3 Latin square design replicated three times; each period lasted 18 days
(10 adaptation days and 8 measurement days). Nine cross-bred (Aberdeen Angus × Hereford) heifers (214 ± 18 kg) fitted with
permanent rumen catheters and housed in individual metabolic cages were assigned to one of three treatments: 24 h access to
TMR ( T), 24 h access to herbage ( H) or combined diets with 18 h access to TMR and 6 h access to herbage ( T + H). Data were
evaluated using a mixed model. Animals fed T+H ( TMR 71% and herbage 29%) diets tended to have a higher dry matter intake
as a proportion of their BW than animals fed T. The T+ H diet did not change ruminal fermentation (pH, N?NH3 and volatile fatty
acids) or the N metabolism relative to the T diet, but increased the glucagon concentration and altered glucose metabolism.
Conversely, animals fed T +H had increased purine derivatives excretion, increased N use efficiency for microbial protein synthesis
and decreased plasma urea and urinary N excretion relative to animals fed H diet. The use of combined diets led to consumption
of nutrients similar to a TMR diet, without reducing nutrient use and could improve N utilization compared with the
herbage-only diet. MenosAbstract: Diets combining herbage and total mixed rations (TMR) are increasingly used in temperate regions for feeding ruminants,
