The Energy Value of Fats and Fatty Acids for Chicks 2. Evaluated by Controlled Feed Intake

摘要: Abstract THE absorbability values of free fatty acid mixtures from hydrolyzed lard and beef tallow were found by Young (1961) to be significantly higher than reported Renner Hill (1958). To evaluate further the utilizable energy in fats, perhaps help explain above discrepancy, it was desirable have another procedure for evaluating fats acids poultry. The comparison response animals fed graded amounts a test material with levels standard has been used quality protein (Hinners Scott, 1957) availability dietary nutrients such as phosphorus (Gillis, Norris Heuser, 1954) zinc (Edwards, 1959). This method is limited fact that substituting fat non-digestible ingredient cellulose alters caloric density…
