Abstract

Taurine, an amino acid synthesized from Met, primarily functions in bile acid conjugation. Four experiments were conducted to determine whether Tau supplementation of broiler cockerels and female turkey poults to 3 wk of age would influence performance and fat retention at different levels of dietary fat. In these experiments, Tau was added at 0 or .8% to a corn and soybean meal basal diet with dietary poultry fat added at 0, 5, or 10%. Taurine did not affect BW gain of broiler cockerels; however, in one experiment feed efficiency was improved (P<.01) during the 1st wk and fat retention was improved (P<.06) at 7 days of age. In experiments with turkey poults, dietary Tau did not affect weight gain but improved feed efficiency (P<.01) during the 1st wk and decreased overall feed efficiency (P<.01) in one experiment. Improvement of fat retention by Tau at 14 days was significant (P<.02) in one experiment and approached significance (P<.07) in the other experiment. Fat supplementation of both the broiler and turkey diets significantly (P<.05) improved weight gain, feed efficiency, and fat retention. Supplementary Tau appears to have little effect on performance of broilers and turkeys.
