BACKGROUND The objective of the study was to investigate the effects of in vitro zinc sulphate additive to semen extender on sperm parameters (progressive motility, viability, membrane integrity and DNA stability) after cryopreservation. MATERIALS AND METHODS In this Prospective longitudinal laboratory study, semen samples of 5 buffalo bulls of 3-5 years old were collected at 5 different occa...

Modern livestock breeding is basically dependent on the proper use of semen for artificial insemination (AI) of females and of other reproductive biotechnologies such as the production of embryos in vitro for embryo transfer (IVP). Both these techniques have made possible not only the wide dissemination of genetic material onto breeding populations but also enhanced the selection of best sires,...

| There are several types of antioxidants which can be use in buffalo semen preservation. The current study was performed to the influence viz., Coenzyme Q10 (CoQ10), L-Carnitine (LC), or N-Acetyl-Cysteine (NAC) added extender on freezability and fertility spermatozoa. Semen Egyptian bulls (n=5) were pooled extended with tris (1:10) without addition antioxidant (E1), i.e., 0.03 mM CoQ10 (E2), 3...

The preservation quality of buffalo semen is poor. The possibility that the cause is inherent in the enzyme system of the spermatozoa and seminal plasma has not so far been systematically studied. There are a few reports on acid and alkaline phosphatase (Eapen, Shrivastava & RazaNasir, 1946; Roy, Pandey & Rawat, 1960; Sengupta, Misra & Roy, 1963; Misra, Singh & Tomar, 1969), but no reports appe...

Air tebu dapat dimanfaatkan sebagai pengencer semen karena mengandung berbagai nutrien yang menunjang kehidupan spermatozoa selama preservasi. Penelitian ini bertujuan untuk menguji kemampuan air dalam mempertahankan daya hidup kambing PE preservasi pada suhu 3-5oC. Semen ditampung menggunakan vagina buatan dan segera dievaluasi secara makroskopis mikroskopis. segar dibagi ke lima buah tabung r...

Understanding and sustaining biodiversity is a multi-disciplinary science that benefits highly from the creation of organized and accessible collections of biomaterials (Genome Resource Banks). Large cryo-collections are invaluable tools for understanding, cataloging, and protecting the genetic diversity of the world's unique animals and plants. Specifically, the systematic collection and prese...
