In a first experiment, the effect of in vitro incubation with Aspergillus niger (An) on the chemical composition of different fibrous substrates was studied. In a second experiment, the effect of incubation time (0, 72 and 144 h) on in vitro digestion with An of dry matter (IVDMD), neutral deterg...

A mechanistic model (COWPOLL) was used to estimate enteric methane (CH4) emissions from beef production systems in Chile. The results expressed as a proportion of gross energy intake (GEI) were compared with enteric fermentation data reported in the last Chilean greenhouse gases inventory, which ...

Enzymatic extracts were prepared from rumen fluid (RF) either directly after collection or after incubation in enriched media and their proteolytic activities were measured and compared The objective of RF in vitro cultivation was to augment enzymatic activity by using diverse incubation media co...
