To identify metabolic indicators in blood and urine for early pregnancy in dairy cows (32 crossbred and 12 purebred zebu cows), blood and urine samples were collected on days 0, 15, 20, 24, and 30 postbreeding. The plasma progesterone (P4) concentration was significantly (P < 0.05) higher in pregnant cows than in nonpregnant cows after day 15. The plasma blood urea nitrogen (BUN) concentration remained significantly (P < 0.05) higher in pregnant cows on day 15. The plasma concentrations of cholesterol, glucose, protein, and nonesterified fatty acid (NEFA) did not differ between pregnant and nonpregnant cows. The urine protein concentration was significantly higher (P < 0.05) in pregnant zebu cows compared to nonpregnant zebu cows. Plasma P4 was significantly (P < 0.001) and positively associated with urine glucose levels in nonpregnant crossbred cows. In nonpregnant zebu cows, the correlation between P4 was positive (P < 0.05) with plasma cholesterol, glucose, urine glucose, and protein. In pregnant zebu cows, P4 was negatively associated with plasma BUN and positively (P < 0.05) associated with both plasma and urine glucose levels. Thus, urinary proteins can be used as a noninvasive tool for early nonpregnancy confirmation in cows with very high accuracy at around 24 days after artificial insemination.

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 …

Optical density image (ODI) analysis, based on the intensity of pixels in digital images, is commonly used in orthopedic medicine. This study was conducted to quantify endometrial and luteal changes in early pregnant and cyclic cows by ODI analysis. Twenty healthy primiparous Simmental cows on days 80?120 postpartum were subjected to ultrasonography and ODI analysis on the days of estrus (day 0) and metestrus (day 4) as well as 12, 15, 18, and 21 days after insemination. The ODI values of pregnant (P) and nonpregnant (NP) cows were compared using two-way ANOVA. The P cows tended to have greater endometrial …
