Aquatic plants and macroalgae as potential feed ingredients in ruminant diets

The aim of this research was to investigate the nutritive value of three aquatic plants, the seagrass ( Ruppia maritima ) and two green macroalgae ( Chaetomorpha linum and Ulva lactuca ). Biomass from three aquatic plants collected from the lagoon Ghar el melh of Bizerte (northeast of Tunisia) was w...

Description
Summary:The aim of this research was to investigate the nutritive value of three aquatic plants, the seagrass ( Ruppia maritima ) and two green macroalgae ( Chaetomorpha linum and Ulva lactuca ). Biomass from three aquatic plants collected from the lagoon Ghar el melh of Bizerte (northeast of Tunisia) was washed and dried, and tested alone (compared to barley grain and barley grass) or included at different levels in isonitrogenous concentrate mixtures. Four rumen cannulated Barbarine rams were used as donors of rumen fluid for in vitro incubations and as hosts for in situ nylon bags rumen incubations. Gas production, fermentation rate, gas produced after 24 h of incubation and apparent OM digestibility were greater for barley grain and grass than for the three aquatic plants ( P
