Comparison between the effects of feeding copper sulphate‐treated and untreated rapeseed cake containing high glucosinolates on rumen fermentation, nutrient digestion and nitrogen metabolism in steers
Abstract:Two trials were carried out to study the effects of copper sulphate (CuSO 4 ) on detoxifying glucosinolates (GLS) in rapeseed cake (RSC) and compare the effects of feeding CuSO 4 -treated and untreated RSC on nutrient digestion and nitrogen (N) metabolism in steers. In Trial 1, different concentrations of CuSO 4 solution (1.6 vs.
g CuSO 4 •5H2 O L −1 ), soaking temperatures (25 vs. 60°C) and drying methods (air drying at 60°C vs. freeze drying) were allocated in a 2 × 2 × 2 factorial arrangement in vitro. In T… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
