Abstract
Artificial insemination programs for horses usually involve ex vivo handling and transporting of sperm. The present experiment was designed to: (i) assess the effect of transportation on sperm DNA integrity at different time post semen collection, and (ii) evaluate if sperm DNA quality deteriorates rapidly beyond 24 h of cooled storage. After collection, the ejaculates were extended using INRA 96 and semen was prepared for prompt analysis (A0) or 24 h/48 h cooled-shipping (B24 and C48 respectively). Each sample was assessed for sperm DNA fragmentation index (SDFI) at time 0 and after incubation for 2, 6 and 24 h at 37 °C. There was very little difference in SDFI between freshly extended (A0) and 24 h/48 h cooled-transported semen samples (B24/C48) at time 0. After 2 h of incubation at 37 °C, there was an increase in SDFI ranging from 2.7% to 7.5% per hour in freshly extended semen samples (A0: 5.1 ± 1.5), while cooled-transported semen samples had a much greater increase in SDFI, ranging from 5.0% to 20.5% (B24: 14.7 ± 5.6) and from 8.2% to 26.8% (C48: 18.3 ± 7.2) respectively. There were not marked differences in the sperm DNA integrity between 24 and 48 h for transported samples, thus there is the possibility of desirable fertility with use of stallion sperm after 48 h of cooled storage.

Anim Reprod Sci 2016; 172:60-75. [PMID: 27449405 DOI: 10.1016/j.anireprosci.2016.07.003] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2016] [Revised: 07/08/2016] [Accepted: 07/12/2016] [Indexed: 10/21/2022]
Abstract
The objective of this study was to design an artificial insemination (AI) protocol using cryopreserved spermatozoa to obtain pregnancies in captive Indian rhinoceroses (Rhinoceros unicornis). Four methods developed varied by timing and approach, as follows; Method 1: females (n=2) were inseminated pre- and post-ovulation under general anesthesia, Method 2: females (n=2) were inseminated pre-ovulation without anesthetic via endoscopy, Method 3: females (n=1) were inseminated pre-ovulation without anesthetic via manual insertion of an insemination catheter, Method 4: females (n=2) were inseminated same as Method 3 with the addition of standing sedation. Semen deposition site varied as a result of changes in AI technology and experience. All females conceived following intrauterine AI using three methods. Four pregnancies (n=3 females) produced via Method 3 and 4 resulted in term births (n=2 male calves, n=2 female calves) at 481.8±12.8days post-AI. Unfortunately, two early pregnancy losses were documented in a fourth female conceiving via Method 2. Pregnancy rates were 0%, 22%, 17%, and 50% for Method 1-4, respectively. Method 3 and 4 rates improved to 29% and 67%, respectively when accounting for AI's conducted only on ovulatory estrous cycles. Spermatozoa (n=5 males) were cryopreserved 0.3-9.3 y prior to successful AI procedures. The lowest dose of frozen-thawed sperm resulting in conception was 500×10(6) motile sperm. Mean time from AI to ovulation in conceptive and non-conceptive cycles was 26±11.8h and 66±80.7h, respectively.
