Variation in Uterine and Serum Proteins During the Reproductive Cycle in Dairy Cows Following Low and High Dietary Protein Intake

Veterinary Medicine and Science, Volume 11, Issue 6, November 2025.
This study investigates the effect of different dietary protein levels (16% and 19%) on serum and uterine fluid protein concentrations in dairy cows at various stages of the reproductive cycle. The results showed that the diet with 19% protein induced significant changes in protein profiles and may enhance reproductive health and performance.

Synchronization of Estrus in Dairy Heifers: A Field Demonstration

Journal of Dairy Science, 1986
Use of prostaglandin F2 alpha to synchronize estrus was demonstrated over 3 yr with 2966 dairy heifers in 45 herds. Reproductive status of all heifers was determined before any injections occurred. Anovulatory heifers (8.3%) were not injected or inseminated. Ovulatory heifers received one intramuscular injection and most heifers received two injections

Gut microbial‐derived 3,4‐dihydroxyphenylacetic acid ameliorates reproductive phenotype of polycystic ovary syndrome

iMeta, Volume 4, Issue 5, October 2025.
By integrating multi‐level and multi‐omics analyses, we identify 3,4‐dihydroxyphenylacetic acid (DHPAA), a gut microbiota‐derived degradation product of dietary flavonoids, as a key bioactive end‐product responsible for the beneficial effects against polycystic ovary syndrome (PCOS).
