Clinical Modalities for Enhancing Reproductive Efficiency in Buffaloes: A Review and Practical Aspects for Veterinary Practitioners.

This review aimed to bring a comprehensive analysis of key clinical strategies for enhancing reproductive efficiency in buffaloes, a species that exhibit low reproductive performance under conventional reproductive management compared to that exhibited by cattle. It considers key ART techniques including estrus synchronization for artificial insemination, and ovulation induction, highlighting their role in improving fertility and overall herd productivity. However, it also addresses common postpartum inflammatory and functional reproductive disorders, discussing their diagnosis and treatment protocols, stressing their impact on the overall reproductive outcome in buffalo farming.

Advancements in Understanding and Enhancing Antioxidant-Mediated Sperm Cryopreservation in Small Ruminants: Challenges and Perspectives.

Cryopreservation poses significant challenges to the preservation of sperm integrity and function, particularly in small ruminants where cryodamage is pronounced. This review explores the molecular mechanisms underlying sperm cryodamage and strategies for improving cryopreservation outcomes, with a focus on the role of antioxidants. Cryopreservation-induced alterations in proteins and RNA transcripts critical for sperm function, including motility, capacitation, fertilization, and embryo development, are discussed.

Economical implications and the impact of gonadotropin-releasing hormone administration at the time of artificial insemination in cows raised in the extensive system in North Romania.

Artificial insemination (AI) is the first and the most used biotechnologies in reproduction all over the world. Many studies reported the beneficial role of gonadotropin-releasing hormone (GnRH) administrated some hours before the AI or at the artificial insemination time. This study aimed to assess the effect of GnRH analogs given at the time of insemination on the first, second, and third AIs and to assess the economical implications of GnRH administration.
