Special Issue Information

Dear Colleagues,

Nowadays, artificial insemination (AI) with fresh, chilled or frozen semen is commonly performed in domestic dogs to avoid mating failure or long journeys bringing the bitch to the stud dog, but also for genetic reasons and breeding programs. In domestic cats, substantial improvements have been achieved in recent years and cat breeders are increasingly seeking to benefit from this reproductive technique. In ferrets, too, AI carries some promise. In wild carnivores, as stated by the IUCN—the International Union for Conservation of Nature—AI is a useful tool that has potential application towards maintaining the viability of in situ populations and restoring genetic connectivity within isolated individuals. Furthermore, it is less dangerous, more cost-effective and more practical to transport preserved spermatozoa than susceptible live animals. In this regard, the development of sperm cryobanking may help to retain the genetic diversity within species. Many conservation programs already include AI in wild mustelids, felids, canids and bears all over the world. More advanced inseminating techniques (trans-cervical intra-uterine or even intra-oviductal deposition of semen, coelioscopy, etc.) have been developed, linked with a reduction of inseminating doses and improvement of fertility results. We believe it is time to provide an update on the use of artificial insemination in domestic but also in wild carnivores and to consider how improvement of this technique in pets may help in the conservation of endangered species.

Areas of interest: artificial insemination; sperm collection, preservation and shipment; cryobanking; pets; dogs; cats; ferrets; felids; canids; mustelids; bears; hyenas; other carnivores; biodiversity conservation programs in endangered carnivores.

We invite you to share your recent findings through this Special Issue.

For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Animals is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs).

The Tsushima leopard cat (Prionailurus bengalensis euptilurus) is an endangered wild felid that lives solely on Tsushima Island, Nagasaki, Japan. Japan’s Ministry of the Environment is working with the Japanese Association of Zoo and Aquariums for ex situ conservation of this species. However, considering genetic diversity, it is difficult to conduct captive breeding programs by natural breeding alone; hence, assisted reproductive technologies are required. This study aimed to breed Tsushima leopard cats, which otherwise cannot be paired, using laparoscopic oviductal artificial insemination (AI). Female Tsushima leopard cats (female 1, aged 7 years; female 2, aged 6 years) were treated with 200 IU equine chorionic gonadotropin, followed by administration of 1000 IU porcine luteinizing hormone (pLH) after 96 h to induce ovulation. Laparoscopic AI was performed 32 h post-pLH administration. Females 1 and 2 were inseminated in the oviduct with 2.4 × 10⁶ and 3.3 × 10⁶ motile spermatozoa, respectively, collected from two males. Pregnancy was confirmed by radiography 45 and 51 days post-AI in females 1 and 2, respectively; one fetus was found in female 2. Moreover, female 2 had spontaneous delivery of a female kitten 66 days post-AI. This is the first successful case of AI in a Tsushima leopard cat. Full article
