The invention relates to a method for detecting early
embryo death of cattle and sheep, which is characterized by comprising the following steps of: 1) determining the detection time of early
embryo death: when oestrus behavior characteristics of cows and ewes are observed by a
pedometer or naked eyes, determining the time as the detection time; 2) detecting early
embryo death: taking 5-10ml of cow and ewe blood, standing for 1-2 hours in a shade place, separating serum, respectively inserting bovine trophoderm
protein-1 detection test paper and sheep trophoderm
protein-1 detection test paper into the cow and ewe serum for 5-10 minutes, observing the detection test paper 15-18 minutes after the detection test paper is taken out, and when the detection test paper develops color, detecting the early embryo death; the cows or ewes are successfully fertilized and form early embryos, but still have estrus behavior characteristics, and the embryos are proved to be dead. Whether embryos die or not can be detected in time, the problems that the feeding cost is increased in the non-pregnant period, the number of fertilization opportunities caused by blind
mating is small, and wombs of cattle and sheep are injured are solved, and by reasonably waiting for
mating, the breeding efficiency is greatly improved, the yield of milk and goat milk is increased, and the income of a feeding farm is increased.
