[Studies on the vitamin requirement and vitamin supply in fattening turkeys. 2. Checking the vitamin supplements to state-approved mixed animal feed for fattening turkeys].
In turkey fattening experiments, the vitamin A, vitamin D3, vitamin B6, vitamin B12, niacine, pantothenic acid, folic acid, biotine and choline chloride additions to mixed feeds for fattening turkeys were checked. The vitamin A requirement of the fattening turkey is met, in all stages of growth, by adding 3,000 I.U./kg feed. For vitamin D3 the necessary supplements are 1,000 and 500 I.U./kg for starter feed and fattening mixes, respectively. The requirements for vitamins B2, B6, B12, niacine, pantothenic acid, folic acid and biotine of the fattening turkey are covered by the respective amounts contained in the ration components. To ensure adequate choline supply (optimum gain, small losses) during the starter period, the addition of 500 mg/kg feed proved necessary. On the basis of the results presented, recommendations are given for requirement norms and mixed feed supplementation that have been fully implemented in the meantime.
