Addressing biases in sliding window analysis gives new insight into the response of parturition date to weather in a wild mammal

Oikos, Volume 2026, Issue 3, March 2026.
Animal breeding phenology in temperate and high latitude regions is often predicted by weather variables, such as temperature. Much work on this topic has focused on taxonomic groups that employ adaptive plastic responses to annual variation in an environmental cue, with analytical approaches developed to determine when weather has an effect and the ...

The Impact of Feeding Organic Trace Minerals Using Advanced Chelate Technology on Reproductive Efficiency and Blood Parameters in Ghezel Ewes

Veterinary Medicine and Science, Volume 12, Issue 2, March 2026.
Supplementing the flushing diet with organic trace minerals based on advanced chelate technology enhanced the reproductive performance of ewes as compared with inorganic trace minerals. ABSTRACT Background The bioavailability of trace minerals (TM) in a diet is important for improving reproductive performance and fertility parameters.

Reproductive and Perinatal Outcomes of Embryo Transfer in Elite Hanwoo Cows

Veterinary Medicine and Science, Volume 12, Issue 2, March 2026.
Reproductive outcomes following embryo transfer in Elite Hanwoo cows differed by embryo production method. OPU‐IVF was associated with higher abortion, increased birth weight of male calves and greater dystocia risk, whereas MOET resulted in more favourable calving outcomes, highlighting the importance of embryo production strategy and periparturient ...

Short‐Term Impact of Betaine Supplementation on Ruminal Microbial Relative Abundance, Nutrient Digestibility, Serum Metabolites, and Milk Composition in Heat‐Stressed Dairy Cows

Veterinary Medicine and Science, Volume 12, Issue 2, March 2026.
Short‐term betaine supplementation (80 g/day for 4 weeks) improved thermoregulation, ruminal fermentation, and nutrient utilisation in heat‐stressed dairy cows. These effects enhanced feed intake, milk yield, and metabolic stability by modulating rumen microbiota and reducing inflammatory and oxidative stress responses.

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 ...
