FIELD: animal science, velvet antlers reindeer breeding.
SUBSTANCE: the capacity for successful insemination should be detected by progesterone level in blood sampled on the 1st d after estrus end. Animals at progesterone secretion level in blood being below 10 nM/l should be stated upon to be dry to be, thus, rejected. Application of the method suggested enables to perform rejection of animals excluding 2-3-yr-long period of inspection, decrease loading while carrying out selection-breeding work.
EFFECT: higher efficiency of rejection. 1 ex, 3 tbl
