Effects of Canola Meal on Absorption and Tissue Levels of Trace Minerals in Rats

Canola and Rapeseed

“…Availability to chicks of minerals in rapeseed meals was generally lower than soybean meal due to their higher PA and fiber contents (Nwokolo and Bragg 1977;. Similar observations were reported in growing pigs (Keith and Bell 1987a) and inrats (Keith and Bell 1987b ) fed canola or soybean meal in a cereal-grain-based diet, with the greatest effect seen for Zn than the other minerals such as Fe, Cu, and Mn. In general, availability of minerals including P in ruminants does not appear to be as much affected by PA as in nonruminants since PA is hydrolyzed by the phytase of the rumen microflora (Reddy et al 1982).…”

Enzyme applications for monogastric feeds: A review

“…(Jacorzynski 1987). These sugars are present at signiftcant levels in lupins and legumes (Sainu 1988 (Keith and Bell 1987) and protein (Lathia et al 1987;Carnovale et al 1988). Both phytase that is presenr in ingredients, such as wheat (Pointillart et al 1987) as well as microbial phytases (Aspergillus ficuum; Nelson et al 1968Nelson et al , 1971 al.…”

Effects of Canola Meal on Tissue Trace Mineral Concentrations in Growing Pigs

“…The sample preparation and analytical methods were the same as those described previously (Keith and Bell 1987) except for the following changes.…”

“…The data were analyzed statistically for treatment effects as a one-way classification using the methods outlined (Keith and Bell 1987 Liver, pancreas, kidney and spleen show the most rapid accumulation and turnover of Zn (Underwood 1971) and would be expected to reflect differences in the intake ofavailable Zn. Such differences have been reported (Prasad et al 1969;Lewis et al 1957) and the present data support these observations.…”
