Parameters of fermentation and rumen microbiota of Nellore steers fed with different proportions of concentrate in fresh sugarcane containing diets
(Taylor & Francis Ltd, 2016-01-01)
The objective of this study was to evaluate the effect of a fresh sugarcane-based diet and different roughage-to-concentrate ratios (70: 30, 60: 40, 40: 60 and 20: 80) on the rumen microbiota associated with rumen fermentation ...
The effect of lipid sources on intake, rumen fermentation parameters and microbial protein synthesis in Nellore steers supplemented with glycerol
(Csiro Publishing, 2014-01-01)
The effects of glycerol with fat sources as a feed alternative were investigated in the ration for Nellore steers (Bos indicus). Eight cannulated steers at 30 months of age with initial bodyweight of 554 +/- 36.0 kg were ...
Effects of rumen fluid pre-incubation on in vitro proteolytic activity of enzymatic extracts from rumen microorganisms
(ELSEVIER SCIENCE BV, 2010)
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 ...
