Abstract: An experiment was carried out to determine the synergistic relationship between soybean oil and beef tallow in supplying energy in broiler diets. Four diets which were formulated to be isocaloric were arranged in a balanced factorial design experiment involving 128 broiler chicks of fat and lean lines. Beef tallow and soybean oj1 were included in the diets at four per cent level and a mixture of these at two per cent level. Control diet used sugar as the principal source of energy. Results of a S8@-day feeding period indicated that birds given the diets containing the lipid supplements performed better than birds fed the control diet. Eirdse fed the oil supplemented diets exhibited significantly greater growth rates which was attributed to improved feed efficiencies and to the higher metabolizable energy of the diets. Abdominal fat content was higher in birds given diets containing oil. A comparison of the fatty acid composition indicated a higher content of unsaturated fatty acids in birds given soybean oil and higher saturated fatty acids in birds provided diets containing beef tallow.

An experiment was carried out to determine the synergistic relationship between soybean oil and beef tallow in supplying energy in broiler diets. Four diets which were formulated to be isocaloric were arranged in a balanced factorial design experiment involving 128 broiler chicks of fat and lean lines. Beef tallow and soybean oj1 were included in the diets at four per cent level and a mixture of these at two per cent level. Control diet used sugar as the principal source of energy.

Results of a S8@-day feeding period indicated that birds given the diets containing the lipid supplements performed better than birds fed the control diet. Eirdse fed the oil supplemented diets exhibited significantly greater growth rates which was attributed to improved feed efficiencies and to the higher metabolizable energy of the diets.

Abdominal fat content was higher in birds given diets containing oil. A comparison of the fatty acid composition indicated a higher content of unsaturated fatty acids in birds given soybean oil and higher saturated fatty acids in birds provided diets containing beef tallow.
