Section 12:68:13:31 - Multiplier breeding flocks certified as S.D. pullorum typhoid clean by origin and sampling

A flock may qualify as a multiplier breeding flock when:

(1) It is composed entirely of birds that originated from S.D. pullorum typhoid clean breeding flocks or from flocks that met equivalent requirements under direct board supervision; and

(2) A sample comprised of at least 25 percent of the birds in the flock has been officially blood tested with no reactors or its progeny has been subjected to a 10-day chick mortality bacteriological examination monitoring program and bacteriological examination of a sample of down shed by chicks in the hatcher from selected hatches. When the blood testing procedure is used, the percentage of the flock included in the sample may be reduced by five percentage points following each year in which there is no evidence of infection on the premises until the required percentage is reduced to zero. The sample tested for identification of a flock under this subdivision must include at least 500 birds the first year, 400 the second year, 300 the third year, 200 the fourth year, and 100 the fifth year and all subsequent years.
