Serum Ionized Calcium Concentrations in Breeding Bitches Over Time in Relation to Mastitis, Metritis and Dystocia in a Guide Dog Population

Veterinary Medicine and Science, Volume 12, Issue 2, March 2026.
Serum ionized calcium concentrations were measured at breeding, pre‐whelping, immediately postpartum, and at weaning timeframes in a population of breeding bitches. Overall, ionized calcium was not associated with the incidence of mastitis, metritis or dystocia, but clinical signs of hypocalcemia were associated with ionized calcium concentrations ...

Effects of Genotype and Laying Stage on Egg Traits and Hatchability in Breeder Geese

Veterinary Medicine and Science, Volume 12, Issue 2, March 2026.
As the laying period advanced from the beginning to the end stage, dry matter, fat, protein and ash contents exhibited a progressive decline, with the highest nutrient concentrations recorded at the onset of lay. ABSTRACT Background Optimizing genotype selection and understanding laying stage‐related changes in egg characteristics are critical for ...

Lactate inhibits glucose‐induced zigzag motility and enhances linear motility in bull spermatozoa by suppressing glycolysis

Andrology, Volume 14, Issue 3, Page 933-945, March 2026.
Abstract Background Energy metabolism and substrate balance are critical determinants of sperm motility and fertility. Linear motility is necessary for sperm forward movement, whereas hyperactivated motility is a prerequisite for fertilization. The preference of metabolic pathways depends on substrate availability which controls sperm motility. However,

The Effects of Supraphysiological Estrogen Levels Observed During In Vitro Fertilization Treatment on Cardiac Electrophysiology

Annals of Noninvasive Electrocardiology, Volume 31, Issue 2, March 2026.
Supraphysiological estradiol levels during IVF significantly prolong PR, QTc, J‐Tpeak, and Tp‐e intervals on ECG, suggesting altered atrial and ventricular conduction. These findings highlight a potential pro‐arrhythmic effect of high E2 states and underscore the need for cardiac monitoring in at‐risk IVF patients. ABSTRACT Supraphysiological estradiol
