Interaction Between Penicillin and Grass Juice Concentrate in Turkeys

Scott (1951a) presented evidence to show that the turkey poult requires an unknown factor present in yeast, distillers’ solubles, skim milk and grass and alfalfa juices. The present study was made to determine the possible need for grass juice concentrate by turkey poults fed a practical diet in the presence and absence of penicillin. Day-old Broad Breasted Bronze poults were vent-sexed and weighed individually. They were then distributed into the experimental groups so as to equalize sex and weight. Each group was comprised of 12 males and 12 females. The poults were reared in electrically heated battery brooders with raised wire floors for the 51 days’ duration of the trial. The percentage composition of the diet fed to group 1 was as follows: corn 15, wheat 26, oat groats 5, dehydrated cereal grass 2, fish meal (68% protein) 2, meat meal 2, dried whey 2, soybean oil meal (50% protein) . . .
