Interactions of Fats and Fatty Acids as Energy Sources for the Chick

摘要: Abstract FATS and fatty acids, like other feedstuff ingredients used as energy sources for the growing chick, have been assigned metabolizable (M.E.) values which are widely in formulation of rations. Experimental findings by Sibbald et al. (1960, 1961) seemed to raise doubts, however, about applicability published M.E. individual substances mixtures different kinds fats. They found that a 50/50 mixture weight soybean oil, having an value 8.46 Cal./g., tallow, 6.94 had 8.41 Cal./g. Simple arithmetic indicated tallow must ben raised 8.36 it was postulated non-degummed oil might contained factor, such phospholipids, increased digestibility tallow. Although reports (Pepper al., 1962; Dangoumau Debruyne, 1963) failed to…
