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

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).…”

Rapeseed Meal in Non-Ruminant Nutrition

“…Rapeseed meal is feed that contains plenty of protein, good amino acid composition but with low and variable amount of energy, because of its high cellulose content and low digestibility of nutrients (Tables 1 and 2). Compared with other feed protein, rapeseed meal has a good amino acid composition, high content of micro and macro elements, especially phosphorus, whose efficiency is better despite the presence of phytic acid but has a lower energy value (Nwokolo andBragg, 1977, Keith andBell, 1987;Stanaćev et al, 2002;Stanaćev et al, 2003;Stanaćev and Kovčin, 2004;Stanaćev et al, 2011). Rapeseed has a higher energy value than soybean and sunflower oil and animal fats if it comes from newer varieties with low erucic acid.…”

Lysine Supplementation of Grower and Finisher Pig Diets Based on High Protein Barley, Wheat and Soybean Meal or Canola Meal, With Observations on Thyroid and Zinc Status

“…(Frandson 1965) and time interval since the last meal (Dauncey et al 1983 reported by Yen et al (1986b) Blood serum levels of Zn (Table 9) showed that pigs fed CM had significanrly lower levels than those fed SBM. This may reflect the effects of phytate in CM (Keith and Bell 1987a) or hber (O'Dell 1984) For personal use only. …”
