The influence of trivalent cations and thermal treatment on ruminal degradability of field bean (<i>Vicia faba</i>) and rape seed (<i>Brassica napus</i>) protein

“…Although studies of these methods began in the 1960's, they have been still continued (Driedger and Hatfield, 1972;Schmidt et al, 1973;Nishimuta et al, 1974;Makkar et al, 1988). Formaldehyde was widely used in experiments both in the laboratory and on animals (Verite et al, 1977, Thomas et al, 1979Phillips, 1981;Antoniewicz et al, 1987;Kowalczyk, 1991).…”

“…A variety of chmical and l^sical Bodifications to reduce degradation of dietary protein have been studied and reviewed (Broderick, 1975;Chalupa, 1975;Ferguson, 1975;Barry, 1976;Amos, I960, Waldo, 1977;Hudson et al, 1970;Hatfield, 1973;Rodriques et al, 1973;Thomas et al, 1979).

“…Formaldehyde-treated aoybean meal waa prepared by treating aoybean meal at 0.8% of the CP with formaldehyde (Thomaa at al., 1979). The urea, aoybean meal, formaldel^de treated aoybean meal+urea and formaldei^de treated aoybean meal+oaaein aupplementa were iaonitrogeneoua (20.4% CP) and contained more CP than did tha control and formaldehyde treated aoybean meal aupplementa (Table )).…”
