[A new system for the quantitative evaluation of the effectiveness of an Eimeria tenella radiovaccine].
The quantitative valuation of efficiency of an Eimeria tenella radiovaccine was performed on the basis of 21 tests under floor-pen conditions and on 34 tests under the conditions of industrial broiler production using the vaccination index, the recycling index and coccidiosis protection index. The immunogenic quality of the vaccine was classified quantitatively by the indices 1 to 4, in which the classes 1 and 2 fulfilled the requirements. Under floor-pen conditions the valuation in the classes 1 and 2 was ascertained on the vaccination index with 76.2%, on the recycling index with 44.4% and on the coccidiosis protection index with 100%. Under the conditions of the industrial mast these values amounted 66.7%, 64.7% and 66.7%.
