Two experiments, each consisting of two trials, were conducted with day-old Nicholas Large White turkey poults to compare the effectiveness of four antibiotics for growth promotion and the utilization of sulfur amino acids. A corn-soybean meal basal diet that contained no supplemental methionine, choline, or inorganic sulfate was used in order to furnish(More)
An experiment was conducted with day-old turkey poults to study the influence of virginiamycin on energy utilization. A 2 X 2 factorial arrangement of treatments was used, which included ad libitum or a 25% feed restriction and 0 or 22 ppm of virginiamycin. Virginiamycin in the diet significantly improved body weight, feed efficiency, and dietary energy(More)
An experiment was conducted with day-old Cobb feather-sexed chicks to determine the influence of virginiamycin on phosphorus. When the average of the three levels of phosphorus were combined, utilization, body weights, and bone ash at 21-days of age were improved by the addition of virginiamycin to the diet. Also the amount of phosphorus required to produce(More)
Two experiments were conducted to determine the effect of the composition of the grower diet and fat in the layer diet on Broad Breasted Large White turkey hens. In Experiment 1, the turkey hens were fed corn-soybean meal diets containing zero and 3% added fat from 12 to 32 weeks of age. In Experiment 2, they were fed a corn-soybean meal basal and a high(More)
Two experiments were conducted to determine the sodium requirement of the Large White turkey hen. A supplementation rate of 0.59 g sodium/kg diet (1.0 g sodium/kg in total) was required for maximum production when the hens were fed a maize-soyabean meal diet. The egg production of hens receiving a diet without added sodium had fallen to zero after 70 d.(More)
Two trials were conducted to compare the performance of Nicholas Large White turkey poults fed diets with three levels of copper in diets with two sources of methionine. A corn-soybean meal diet, containing 26.5% protein, was used. The two methionine sources were fed at 0 and .06% in diets containing 0, 500, and 750 ppm of copper supplied by CuSO4 X 5H2O.(More)
Two experiments were conducted to determine the influence of graded levels of salinomycin on the performance of broiler chicks. Cobb feather-sexed chicks were fed experimental diets from 1 to 21 days of age. A significant depression in body weight and feed consumption was obtained when the feed contained 77 ppm of salinomycin. Body weight and feed(More)
Two trials were conducted to determine the need for niacin supplementation of Nicholas Large White Turkey hens fed a corn-soybean meal diet from 224 to 336 days of age. Analysis of the corn and soybean meal indicated the niacin contribution to be 23.6 mg/kg diet. No supplemental niacin was required for maximum egg production, fertility, or hatchability.(More)
The effect of increasing levels of zinc methionine hydroxyl analog chelate (ZMHAC) on male broiler growth was evaluated. Three experimental treatments were used in the evaluation; 30 ppm, 40 ppm, and 60 ppm and a control that contained 100 ppm of zinc sulfate . All other trace minerals were fed at consistent concentrations. Each treatment included 15(More)
Two experiments were conducted to determine the effect of adding ipronidazole to the diet of turkey poults containing two different levels of methionine. A corn-soybean meal diet with 0 to .18% supplemental methionine was fed to Nicholas Large White poults from 1 to 21 days of age. The addition of .18% supplemental methionine significantly improved body(More)
