Lack of Effect of a Synthetic Poultry Feed Flavor on Chick Growth and Feed Efficiency

ASERIES of three feeding trials of four weeks duration were run to determine whether a synthetic poultry feed flavor had any influence upon chick growth and feed efficiency when incorporated into a practical chick starting ration. The poultry feed flavor contained extractives of anise, rose, cinnamon, lemon and orris with soya meal and corn sugar used as carriers. The experimental design is presented in Table 1. Fish meal was added at the 4 percent level at the expense of the total ration whereas 4 percent of pork fat was added at the expense of corn and the protein adjusted by increasing the soybean meal. The synthetic flavor was added at the rates of ¼, ½, and 1 pound per ton (125 ppm., 250 ppm., and 500 ppm. respectively). Day-old straight run New Hampshire X Silver Cornish chicks were distributed into groups of 30 chicks each in experiments 1 and 2, …
