The aim of this research was to reveal the impact of bioelemental status of dairy cows on intrauterine growth restriction and embryo death at early gestation stages. The research included 22 Holstein cows with average annual dairy productivity of 6400-7600 kg. All animals were subjected to transrectal ultrasonography to determine corpus luteum and pregnancy status, and their blood was sampled for biochemical analyses on the 19th-22nd, 28th-32nd, and 38th-45th days of gestation. Zinc, copper, manganese, and selenium blood contents were determined by atomic absorption spectrophotometry. Serum levels of calcium, phosphorus, and magnesium were determined with an automatic biochemistry analyzer. Protein-bound …
