The aim of this study was to assess the relationships of hepatic triacylglycerol (TAG), plasma glucose, plasma cholesterol, and plasma urea nitrogen (PUN) concentrations with the morphological quality of oocytes obtained from 20 Carora breed lactating cows at days 20 and 35 postpartum in a commercial farm. Oocytes were obtained through the technique of transvaginal ultrasound-guided follicle aspiration. Change in body condition score (0.35 vs. 0.44, P = 0.02) and mean plasma cholesterol (3.59 vs. 4.35 mmol/L, P = 0.01) significantly differed between the 2 periods, whereas mean TAG tended to be higher at day 35 after calving (2.29 vs. …

This research was conducted to study hormonal and metabolic statuses and to determine ultrasound criteria for early diagnosis of fetal growth retardation syndrome (FGRS) in dairy cows of Black-motley (n = 41) and Red-motley (n = 56) Holstein breeds. Concentrations of progesterone, testosterone, 17beta-estradiol, dehydroepiandrosterone sulfate, cortisol, and triiodothyronine in blood serum were assessed by immune-enzyme analysis. Concentrations of plasma L-ascorbic acid and nitrogen oxides, serum immune globulin, middle molecular peptides, and bactericidal and lysozyme activity were determined by spectrophotometry. On days 38-40 and 60-65 of gestation, FGRS in cows was associated with hypoprogesteronemia, decrease of adrenal and thyroid gland …

The aim of this study was to investigate the effects of the use of Theranekron alone or in combination with intramammary antibiotic therapy for the treatment of subclinical and clinical mastitis on the recovery rate from mastitis. The study material was composed of 177 mammary lobes of 63 Holstein cows with subclinical (groups S1 and S2) and clinical mastitis (groups C1, C2, C3, and C4). In all of the treatment groups, excluding group S2, the California mastitis test scores were determined to have decreased after treatment (P < 0.05). In groups C1, C2, C3, and C4, which were treated for clinical mastitis, the somatic cell count (SCC) values were observed to have decreased. The decrease in SCC values was statistically significant except in group C2 (P < 0.01). While the SCC values were observed to have decreased in group S1 (P > 0.05), which was treated with Theranekron alone, the same values were found to …
