Captive breeding of clouded leopards (Neofelis nebulosa) is challenging because of mating incompatibility, high incidence of teratospermia in males, and inconsistent ovulation patterns in females. Assisted reproductive techniques, therefore, are necessary to overcome these issues and maintain the genetic diversity in the captive population. The objective was to use laparoscopic oviductal artificial insemination (AI) to breed genetically valuable females (n = 4; aged 4.

Article Synopsis
  • - The study focuses on using IVF and embryo transfer to help sustain endangered Eld's deer populations, evaluating how FSH hormone injections affect oocyte collection and embryo development quality.
  • - Experimental results showed that while FSH stimulation increased the size of follicles, it did not significantly improve the number or quality of oocytes collected, nor the overall success rate of embryo cleavage post-IVF.
  • - Notably, the experiment led to the first successful birth of a live Eld's deer fawn from in vitro-produced embryos, highlighting potential advancements in conservation techniques for this species.

Article Synopsis
  • The Asian tapir is classified as Endangered, highlighting the need for effective conservation efforts and genetic management.
  • Researchers analyzed mitochondrial DNA sequences from 37 captive Asian tapirs in Thailand, identifying 11 distinct haplotypes through their genetic variations.
  • Phylogenetic analysis revealed three genetic clades, providing insights that can aid in the conservation of both captive and wild populations to ensure their stability.

Asian tapir (Tapirus indicus) is categorized as Endangered on the 2008 IUCN red list. The first full-length mitochondrial DNA (mtDNA) sequence of Asian tapir is 16,717 bp in length. Base composition shows 34.

Due to human activity and a reduction in the size and quality of wetland habitats, populations of the Eastern sarus crane (Grus antigone sharpii) have declined dramatically across their range in Southeast Asia. Conservation efforts in Thailand have focused on reintroduction of the founders harboring the highest genetic diversity. One of the most important requirements to ensure the persistence of the reintroduced populations is a balanced sex ratio.

A 40-yr-old male captive chimpanzee (Pan troglodytes) presented with depression and anorexia for 7 days. The tentative diagnosis, following a physical examination under anesthesia, was pneumonia with sepsis. Despite antibiotic treatment and supportive care the chimpanzee died a week following presentation.

Intergeneric nucleus transfer (ig-NT) is a promising technique to produce offspring of endangered species. The objectives of this study were to (1) investigate the in vitro development of marbled cat (MC; Pardofelis marmorata) and flat-headed cat (FC; Prionailurus planiceps) ig-NT embryos reconstructed from domestic cat (DC; Felis catus) oocytes (Experiment 1), (2) evaluate the effect of individual FC donor cell lines on NT success (Experiment 2), and (3) assess the developmental ability of FC-cloned and DC-IVF embryos in vitro and in vivo after oviductal transfer (Experiment 3). In Experiment 1, the morula rate of FC-reconstructed embryos was significantly higher than those of MC and DC embryos but lower than that of parthenogenic DC embryos.

The objective of the study was to investigate interspecies Somatic Cell Nuclear Transfer (iSCNT) techniques in marbled cats (Pardofelis marmorata), using domestic cat and rabbit oocytes as the recipient cytoplasm. The recipient oocytes were obtained from ovariohysterectomized cats and superovulated rabbits. The donor cells were collected from a male marbled cat that had died in captivity.
